Dissemination of ‘real time’ meteorological information to domestic aviation community

Published

on

On July 3, 1971, during the first JVP insurgency, while I was working with the then Royal Ceylon Air Force (RCyAF), based at China Bay, in Trincomalee, I reported to the squadron early morning and was told by our Officer Commanding the No. 3 Maritime Squadron, Flt Lt Denzil Fernando, that I was assigned to fly as ‘Second Dickie’ to Sergeant-Pilot Tony (Tuan Mohamed Zachariah) Dole in a de Havilland Dove with serial (registration) CS 406. We were to go to Vavuniya to pick up the then Government Agent (GA), Neville Jayaweera, and take him to Ratmalana (RMA).

Our trip to Vavuniya was uneventful, except that the runway, unused for many years, had been cleared and secured by the Army, with soldiers standing at regular intervals along the full length of the runway. After the GA boarded the plane we got airborne and set course for Ratmalana. It was a bit cloudy when we started. Soon the clouds got heavier, and we had to fly through the clouds to maintain our course. Not long afterwards, the weather became worse, and turbulence in the clouds caused our eight-seater D.H. 104 Dove to shake like a leaf in the wind.

The twin-engine transport plane didn’t have Airborne Weather Radar (AWR) to avoid rain clouds. AWR works on the principle that the more turbulent a cloud, the greater the mass of water it will support. This will ‘bounce’ off radar signals emitted by the aircraft, and will be proportional to the cloud thickness, thereby providing an image of the turbulence, within the cloud mass, as indicated on a screen in the cockpit of the aircraft.

Without AWR, our only option was to reduce speed to make the ride as comfortable as possible for the GA (and us), not unlike when driving on a bumpy road, and then ‘eyeballing’ the weather and hoping for the best by avoiding the more intense rain clouds. The only weather forecast reports available to us were for China Bay and Ratmalana airports, but no information whatsoever on observed weather en route.

By now, flying in cloud, we had lost sight of the ground and were unsure of our position. We were avoiding clouds to the best of our ability. The vertical development of some of the clouds were in excess of 10,000 ft at some places. So we decided to go below the cloud base, which was fortunately higher than existing terrain, so we could maintain sight of ground or water to pinpoint our position. In aviation parlance, this is known as a ‘visual fix’ of position.

We also flew further west towards the coast to reduce the chances of rising terrain (hills). Soon we spotted, through the rain, the unmistakable coastline, of Kalpitiya and Puttalam, enabling us to positively establish our position. We then continued to follow the coastline at low leve,l to RMA, flying under the jet aircraft approach path at Bandaranaike International Airport (BIA), Katunayake, and towards Colombo.

The air traffic control towers at Katunayake and Ratmalana were also reporting heavy rain showers. We found a patch clear of cloud, south of the Ratmalana airport, over Bolgoda Lake, and began circling there. But Sgt. Dole had an ace up his sleeve. He told me that showers present under cloud cells usually come in waves that transit the airport, and the best bet was to wait and land between the showers that we could see well from our vantage point in the south.

Sure enough, as soon as one rain shower passed the airport, we were well positioned to turn in and land in relatively clear weather with only a slight drizzle, before the next downpour hit.

This was exactly 50 years ago. We didn’t have radio navigational aid, except the Non-Directional Beacons (NDBs) at China Bay, BIA and Ratmalana that operated on low to medium frequency and were affected by bad weather (thunderstorms) and thus rendered useless in our circumstances described here. In fact, the signals emitted by Radio Ceylon were sometimes stronger! In addition, there were two Very High Frequency (VHF) Omni Radio Range stations (VORs) at BIA and RMA, but our aircraft was not equipped with a receiver that could be used in conjunction with the VORs. They were meant for the ‘big aircraft’. Other countries had Distance Measuring Equipment (DME) associated with the VOR, but not Ceylon.

Therefore, pilots had to navigate by a process called ‘Dead Reckoning’, which involved estimated ground speed and time over known ground features (cities, rivers, roads, railway lines and buildings for example). ‘If you reckoned wrong you were dead!’ To add insult to injury, we didn’t have ‘real-time’ observed meteorological information available to us in terms of cloud base and intensity of rain to help us make informed decisions as to what route to follow.

Today, technology has improved worldwide in leaps and bounds. We have ‘smart’ cellular phones and tablets with Global Positioning Systems (GPS). We have capabilities of providing better facilities to domestic air traffic, consisting of landplanes, seaplanes and helicopters. For many years we have had a radar station positioned on Pidurutalagala, the highest point in the island. In fact, we can even monitor certain areas of South India.

Unfortunately, real-time meteorological information is still not available as Sri Lanka has not invested in a communications system capable of providing such information. More than 15 years ago, Singapore installed a radar system at Changi Airport that was capable of giving information to pilots on the intensity of rainfall relative to their airports. We are told that Sri Lanka’s Meteorological Department invested Rs.200 million, in 2013, on a Doppler radar system which, in their so-called ‘wisdom’, they wanted to site at Deniyaya. But it was never installed, and the equipment is now in storage in damaged condition after it went ‘down the pallang’ while being transported there!

Today, there are many free websites which provide highly accurate satellite-based weather forecast information at a click of a button. It is also available on ground to flight dispatchers. It is therefore sad to note that the weather forecasts, produced by our Meteorological Department (who should be playing a key role) are not used by the aviation community, almost certainly due to a lack of confidence on the part of pilots and aviation operations officers. It should also be noted that in Sri Lankan domestic aviation, along with the satellite weather forecasts, the actual observed weather, must go hand in hand. Even this is still not provided by the Met’ Department. I believe that this is a major lapse.

The following incident illustrates the stark reality of what the current situation is for domestic operators. A few days ago, a commercially important passenger (CIP) was flown to Anuradhapura by a domestic air charter company to attend celebrations commemorating the two-year anniversary in office of President Gotabaya Rajapaksa. The outbound flight to Anuradhapura was uneventful. For the return flight to RMA, the flight dispatcher based at Ratmalana had to plan the flight. While the general weather forecast was rain, standard practice relied on the observed actual en route weather by police stations on the way: at Galgamuwa, Nikaweratiya, Kuliyapitiya, Divulapitiya, Palavi, Chilaw, Wenappuwa and Negombo.

All these observers are local police personnel, not qualified aviation or meteorological professionals. Consequently, their very subjective ‘met reports’ are along the lines of “the sky is dark”, “it is about to rain”, “it is now drizzling” or “heavy showers”, from which the flight dispatcher has to form a mental picture of what the en route weather is. One wonders what the insurance implications would be if an accident occurs.

To continue, the hapless pilot at Anuradhapura, who was in touch with his dispatcher on his cellular phone before departure, had to evaluate the risks and make an informed decision. Like Sgt. Dole and I did 50 years ago, he had to get airborne and ‘play it by ear’, so to speak. So, having reached the western coastline, he followed it all the way to Ratmalana. As a matter of interest, I was able to follow the progress of this single-engine light aircraft through one of the free apps on my smartphone, via satellite. That is what prompted this article.

I regard it as an absolute shame that in the last 50 years the Colombo Met’ Department has been unable to provide useful ‘real-time’ meteorological observations to domestic air operations. Yet to satisfy the international aviation community in the gathering of weather data, they have observation stations at all of Sri Lanka’s international airports. But it is a case of thus far and no further. Scrutinising the Meteorological Department’s website will reveal that they have weather observation stations in Kankesanturai (KKS), Jaffna, Mullaitivu, Vavuniya, Mannar, Trincomalee, Anuradhapura, Mahailluppallama, Puttalam, Batticaloa, Kurunegala, Kandy, Nuwara-Eliya, Badulla, Diyatalawa, Pottuvil, Ratnapura, Katunayake, Ratmalana, Galle and Hambantota. These stations are connected to the World Weather Watch (WWW) through a Global Telecommunication Network (GTS). I do not know whether they are automatic as in other parts of the world, or require a qualified human observer.

The sad part is that this real-time information is not available to domestic aviation operators (of both fixed-wing aircraft and helicopters) who have to rely on amateurish police station observations and information. If the observed real-time weather is brought online with a good communications network comprising more observation stations established at all the other domestic airports, weather updates will enhance and synergize air safety in real-time.

I do not know who is responsible for this unacceptable state of affairs, but certainly the Civil Aviation Authority Sri Lanka (CAASL), Airports and Aviation Sri Lanka (AASL), the Sri Lanka Air Force (SLAF), and the ‘keepers’ of some of the domestic airports should coordinate with the Met’ Office and have real-time weather reports available for all domestic flights.

More recently it has been reported, in the local media that the Colombo Met’ Office and Japanese International Cooperation Agency (JICA) have signed an agreement for two more weather radar stations, to be sited at Puttalam and Pottuvil, to replace the one that never ‘got off the ground’ at Deniyaya. Will JICA be able to help in establishing automatic observation stations accessible to domestic aviators, to determine and report on such vital meteorological data as cloud base, intensity of rain, wind direction and speed, and temperature, as a fundamental component of good communication?

It is sad that the ‘end users’ are never consulted in important matters such as these.

US’ anti-migrant stance set to intensify tensions in Western camp

Published

on

The announcement by the US authorities of an anti-migrant stance during a recent commemoration in France of the epochal D-Day Landings of June 6, 1944, ought to strike impartial observers as a supreme irony. Whereas what should have been expected was a vibrant celebration of the beginning of the process of Western Europe freeing itself decisively from Nazi or fascist control during the crucial stages of World War Two, this was not to be.

What the world heard instead was a call to contemporary Western Europe to arm itself against a seemingly rising and threatening migrant presence in the region. In other words, the migrant must be despised and ‘shown the door’.

Instead of a commemoration that rejoiced in the flourishing of liberal democracy and its values what one got was a strong affirmation of fascism and racial chauvinism. US Defense Secretary Pete Hegseth vented his spleen against the migrant or foreigner presence in Europe reportedly thus: ‘Sadly today different European beaches are stormed by different dangerous ideologies.’ To ‘beaches in Spain and Italy and Greece and Bulgaria, boats and men arrive. When will European capitals do something about that invasion?’

While at the outbreak of World War Two it was Nazi Germany that was doing the invading and bringing some principal European countries under its suzerainty, this time around we are being given to understand that it’s migrants to the West who are seeking to colonize the latter. It goes without saying that such inflammatory rhetoric would have the deleterious effect of keeping racial tensions alive in the West and jeopardize all possibilities of the countries concerned cementing and maintaining social stability.

The Trump administration gives the impression of taking a leaf from the politically underdeveloped regions of the South to keep the US polity stable and united. In South Asia, for instance, we are not short of ambitious demagogues who use what is referred to as the ‘race card’ to gather unto themselves a following and thereby further their political fortunes. By seeking to stir and sustain anti-migrant hysteria, the Trump administration is also essentially replicating Nazi Germany’s policy of anti-Semitism. That is, fascism is very much alive in the US under President Trump.

Such efforts at churning racial hysteria at this juncture in the US should not come as a surprise. For all intents and purposes, the Trump administration is nowhere near achieving its aims in West Asia, for instance, in the short term. It has failed to bring Iran down to its knees, as it hoped to do, but is adopting the expedient of keeping the world guessing and confused on what it is doing in the region, since it cannot withdraw from the theatre in a hurry without losing face.

While perhaps working out an escape strategy the Trump administration it seems, is hoping to maintain its following at home intact and silent by playing on their racial biases and insecurities. Hence, the anti-foreigner campaign.

Simultaneously, the Trump administration will need to keep a close eye on how economic pressures on the domestic front are panning out. Anti-administration sentiments first break to the surface at meal tables. On this score, the news cannot be good because the average US family’s spending power ought to be shrinking on account of rising energy and oil prices. Consequently, it would not be a bad idea to keep the attention of the US consumer diverted by adeptly playing ‘the race card’; once again, lessons from intellectually bankrupt Southern politicians are coming in handy.

To be sure such comparisons many politicians in vibrantly democratic countries would find quite unflattering. But the stark truth is that racism cannot be tolerated in civilized societies and those politicians who resort to it risk being branded as racists of the first degree. In fact they could be seen as being on par with the likes of German dictator Adolph Hitler and his close collaborators.

However, on the question of migrant policy the Trump administration would likely be at polar opposites with the most vibrant of liberal democracies of the West. This will be the case with the UK, France and Italy for instance. The latter continue to keep their doors open to legal migrants and they are likely to view a virtual blanket ban on migrants as reprehensible.

Moreover, in the foremost democracies of the West debates are vibrantly ongoing on the need to keep racism or any hint of it completely outlawed in the public plane. There is the case of the UK, for instance, where the authorities continue to emphatically pinpoint their adherence to the principle of anti-racism in the conduct of public affairs.

One proof of the above was the parliamentary debate relating to the killing of 18-year-old Henry Nowak in Southampton. Police handling of the victim came in for sharp scrutiny by particularly the opposition in the House of Commons but there seemed to be a consensus over the main political divide that the matter should not be politicized.

Moreover, the UK authorities stressed in the House the government’s strict adherence to the policy of non-racism. It was also pointed out that British institutions set up to manage racism at the national, county and neighbourhood levels, for example, were very much intact. In fact, Sri Lanka could gain considerably by studying and implementing locally, legislation modeled on the relevant UK laws if it is in earnest when it speaks of ‘reconciliation’.

Accordingly, it is highly unlikely that Western Europe would ‘cave in’, so to speak, to US pressure on issues related to migration. The liberal democracies of Western Europe in particular would remain for the foreseeable future migrant-welcoming, multi-ethnic and plural democracies.

Nor is it likely that Western Europe would be passively receptive to US demands that it drastically increases its defense spending to meet the latter’s aims. Within the Western fold the EU is remaining committed to backing Ukraine, for instance, in its ongoing armed resistance to the Russian invasion and it is not giving any indication of being deferent to US pressure.

However, although tensions would continue to bristle within US-Western Europe relations on the above and numerous other matters of contention it would be far too premature to announce a parting of company between the two sections of the West. In that sense, the post-World War Two order remains essentially intact. There are still many things in common between the two, particular on the economic plane, that will ensure the continuance of the partnership.

A decade among Yala’s ghosts of gold

Published

on

YM75 "James" surveys his territory from a tree-top vantage point, demonstrating the leopard's commanding presence in the landscape.

The first rays of dawn creep over the ancient rocks of Yala. The Indian Ocean glimmers in the distance, and the wilderness slowly awakens. Somewhere amid the scrub jungle, a pair of amber eyes scans the landscape.

For wildlife conservationist and leopard researcher Milinda Wattegedara, moments such as these have defined more than a decade of dedication to one of Sri Lanka’s most iconic creatures—the Sri Lankan leopard.

What began as fascination evolved into a remarkable conservation journey that has transformed the understanding of Yala’s leopard population and placed Sri Lanka firmly on the global wildlife research map.

“Long before I ever lifted a camera, leopards had already captured my imagination,” says Wattegedara. “What fascinated me was not merely their beauty but the complexity of their lives—their hunting strategies, movements, reproductive behaviour and their remarkable ability to adapt to changing environments.”

That fascination led to the birth of the Yala Leopard Diary in 2013, an ambitious long-term project dedicated to documenting individual leopards and unraveling the mysteries surrounding their lives.

For many visitors, a leopard sighting is a fleeting thrill. For Wattegedara and his team, every encounter is a chapter in an ongoing scientific story.

“Each photograph was never the end of an encounter,” he explains. “It was the beginning of deeper questions. How did a particular leopard use the landscape? How did its behaviour change with the seasons? What environmental pressures shaped its decisions?”

These questions drove years of meticulous fieldwork. Every sighting was carefully recorded with details including location, habitat, behaviour, date and time. Photographs were analysed to identify individual animals through unique spot patterns, allowing researchers to distinguish one leopard from another with remarkable accuracy.

What followed was groundbreaking.

YF77 “Shelly” pauses in quiet observation, embodying the alertness
and grace that define Yala’s leopard population.

From 2013 to 2026, the Yala Leopard Diary identified an astonishing 189 individual leopards within the Yala Block 1. The research revealed a leopard density of approximately 0.524 leopards per square kilometre, making Yala one of the highest leopard-density landscapes ever recorded anywhere in the world.

Such findings have elevated Yala’s status among global wildlife researchers.

Nestled between the Indian Ocean and a mosaic of habitats, ranging from rocky outcrops to dense scrub forests, Yala offers an ecological stage unlike any other.

Here, leopards are photographed silhouetted against ocean horizons, perched atop ancient granite formations, resting on tree branches and stalking prey across sunlit grasslands.

The images tell stories of extraordinary lives.

There is Haminee, a devoted mother navigating the challenges of raising cubs in a competitive landscape. There is Lucas, one of Yala’s most frequently documented males, striding confidently across the Gonalabba Plains with the vast ocean forming an unforgettable backdrop.

There is Ruki demonstrating the species’ incredible strength by hoisting prey onto branches, and Shelly, quietly surveying her surroundings in a moment of feline vigilance.

Together, these individuals have become familiar characters in a living wilderness drama.

YM31 “Ruki” secures prey on a branch, illustrating the remarkable strength and coordination of the Sri Lankan leopard.

Recognising the immense value of long-term documentation, Wattegedara joined forces with fellow researchers Dushyantha Silva, Raveendra Siriwardana and Mevan Piyasena to establish the Yala Leopard Centre in 2020.

Located at the Palatupana entrance to the Yala National Park, the centre is believed to be the world’s first information facility dedicated exclusively to leopards.

“The centre serves as a repository of knowledge, accumulated through years of observation and research,” Wattegedara says. “Our goal is to connect visitors with the science behind conservation and foster a deeper appreciation of these magnificent animals.”

The project’s impact extends far beyond Sri Lanka’s borders.

Research arising from the Yala Leopard Diary has been published in internationally recognised scientific journals. One study introduced an innovative framework for identifying individual leopards, while another documented an extraordinary and previously unrecorded case of a leopard cub being consecutively adopted by two different adult females—first a relative and later an unrelated leopardess.

The discovery attracted international scientific attention and highlighted the complexity of leopard social behaviour.

Yet for Wattegedara, the most important lesson remains one of humility.

“One conclusion has become increasingly clear,” he reflects. “Our understanding of these leopards remains far from complete. We are only beginning to understand how they live, adapt and persist in one of Sri Lanka’s most dynamic protected landscapes.”

YF15 “Hope” descends Rukvila Rock at dawn, showcasing the agility and adaptability of Yala’s leopards.

His words underscore an essential conservation truth: the more we learn about nature, the more mysteries emerge.

As Sri Lanka navigates growing environmental challenges, the Yala Leopard Diary stands as a shining example of what sustained observation, scientific curiosity and public engagement can achieve.

Beyond the stunning photographs and remarkable sightings lies something even more valuable—a growing body of knowledge capable of informing future conservation decisions and ensuring that future generations inherit a wilderness where leopards continue to roam free.

For more than a decade, Wattegedara and his colleagues have followed the tracks of Yala’s elusive predators through dust, rain and scorching heat.

Their work has revealed that every leopard has a story, every sighting has significance and every photograph can contribute to conservation.

And perhaps, most importantly, it has reminded us that the golden ghosts of Yala still have many secrets left to share.
