More on cloud seeding

On Monday, March 21, 2022, Minister of Energy, Pavithra Wanniarachchi, complained to reporters that all of the island’s reservoir levels are depleted, therefore reducing their ability to produce hydro-electricity, which in turn results in frequent power cuts. The next day, data produced by the National Oceanic and Atmospheric Administration (NOAA), USA, showed that skies over the catchment area were covered by cloud. (See photo).
How do these clouds form inland? Mainly by evaporation of water in the reservoirs (90%), and by transpiration from trees (10%) and agricultural plants in the area. Western studies reveal that “an acre of corn gives off about 3,000-4,000 gallons (11,400-15,100 litres) of water each day, and a large oak tree can transpire 40,000 gallons (151,000 litres) per year.” Deep roots can extract water from the water table.
A search of the Internet fails to reveal any data for Sri Lanka. Unplanned tree cutting in the past, and removal of topsoil purely for economic benefit by local ‘robber barons’, have done untold damage in the central hills.
Usually, evaporated and plant-transpirated water vapour moves upwards in the atmosphere, then expands due to low pressure and cools down in keeping with a phenomenon known as adiabatic cooling. It amounts to approximately 2 degrees Celsius per thousand feet. The water vapour then condenses around minute particles of dust, releasing latent heat in the process and making the moist air warmer than the surrounding atmosphere. This moist air is unstable and produces clouds rising to a height of 50,000 ft or more in the tropics.
Many years of research have shown that at this stage of cloud development, if the number of these minute solid particles can be artificially increased by aerial spraying a mixture of dry ice (carbon dioxide), salt (sodium chloride) and silver iodide, the volume of rain could be enhanced significantly. This is known as ‘cloud seeding’.
Two researchers, Arvind Kumar and Amitha Tripathi, confirm through mathematical analysis that cloud seeding not only increases rainfall, but also increases the agricultural crops as well as clouds in the atmospheric environment. Therefore, it is a self-sustaining cycle of nature.
Although it is now March/April and the sun is fast reaching overhead on its east/west passage, the so-called ‘inter-monsoon’ period, between the northeast and southwest monsoons, actual rainfall is scanty. In earlier times the inter-monsoons sometimes brought more rain with thunderstorms than the monsoon itself. Now, there is hardly any wind, and one feels ‘muggy’ due to high relative humidity in the atmosphere.
I am at a loss to understand why our so-called scientific community and meteorologists are slow to react. It is all a matter of timing. Drastic times need drastic actions. The Sri Lanka Air Force is equipped to carry out these activities, but seems to have got its priorities mixed up and become involved in farming instead.
First, we must have enough water for agriculture and electricity. The cost of the cloud seeding operation would be less than refurbishing their old MiG fighters in the Ukraine or Russia, for which they have reportedly obtained government permission. There is, however the ‘small matter’ of those two countries being currently engaged in a war which could postpone that project indefinitely.
Undoubtedly the SLAF is equipped with men and machines. We are repeatedly told that the authorities are so ‘pig headed’ that they don’t listen to reason. After all, the proof of the pudding is in its eating.

HW Cave saw Nanu Oya – Nuwara rail track as “exquisite”

Plans to resurrect the Nanu Oya – Nuwara Eliya rail track are welcome. The magnificent views from the train have been described by H W Cave in his book The Ceylon Government Railway (1910):
‘The pass by which Nuwara Eliya is reached is one of the most exquisite things in Ceylon. In traversing its length, the line makes a further ascent of one thousand feet in six miles. The curves and windings necessary to accomplish this are the most intricate on the whole railway and frequently have a radius of only eighty feet. On the right side of the deep mountain gorge we ascend amongst the tea bushes of the Edinburgh estate, and at length emerge upon a road, which the line shares with the cart traffic for about a mile. In the depths of the defile flows the Nanuoya river, foaming amongst huge boulders of rock that have descended from the sides of the mountains, and bordered by tree ferns, innumerable and brilliant trees of the primeval forest which clothe the face of the heights. In this land of no seasons their stages of growth are denoted by the varying tints of scarlet, gold, crimson, sallow green, and most strikingly of all, a rich claret colour, the chief glory of the Keena tree’.
However, as in colonial times, the railway should be available for both tourists and locals so that splendid vista can be enjoyed by all.

LG polls, what a waste of money!

If the people of this country were asked whether they want elections to the local government, majority of them would say no! How many years have elapsed since the local councils became defunct? And did not the country function without these councils that were labelled as ‘white elephants’?
If the present government’s wish is to do the will of the people, they should reconsider having local government elections. This way the government will not only save a considerable amount of money on holding elections, but also save even a greater amount by not having to maintain these local councils, which have become a bane on the country’s economy.
One would hope that the country will be able to get rid of these local councils and revert back to the days of having competent Government Agents and a team of dedicated government officials been tasked with the responsibility of attending to the needs of the people in those areas.

What not to do

By Dr Upul Wijayawardhana
It is immaterial whether you like him or not but one thing is crystal clear; Donald Trump has shown, very clearly, who is the boss. Surely, presidents of two countries are equal; perhaps, that is the impression Volodymyr Zelensky had when he went to the White House to meet Trump but the hard reality, otherwise, would have dawned on him with his inglorious exit! True, the behaviour of President Trump and VP Vance were hardly praiseworthy but Zelensky did what exactly he should not do. Afterall, he was on a begging mission and beggars cannot be choosers! He behaved like professional beggars in Colombo who throw money back when you give a small amount!!
Despite the risk of belonging to the minority, perhaps of non-Americans, I must say that I quite like Trump and admire him as a straight-talking politician. He keeps to his words; however atrocious they sound! Unfortunately, most critics overlook the fact that what Trump is doing is exactly what he pledged during his election campaign and that the American voters elected him decisively. When he lost to Biden, all political commentators wrote him off, more so because of his refusal to admit defeat and non-condemnation of his supporters who rioted. When he announced his intention to contest, it only evoked pundits’ laughter as they concluded that the Republican Party would never nominate him. Undaunted, Trump got the party to rally round him and won a non-consecutive second term; a feat achieved only once before, by Grover Cleveland around the end of the nineteenth century. His victory, against all predictions, was more decisive as he got more collegiate votes and, even though it does not matter, won the popular vote too which he did not get when he got elected the first term. Even his bitterest critics should accept this fact.
Zelensky was elected the president of Ukraine after the elected pro-Soviet president was deposed by a ‘peoples revolution’ engineered by the EU with the support of USA. After this, the EU attempted to bring Ukraine to NATO, disregarding the Munich agreement which precipitated the Russian invasion. He should have realised that, if not for the air-defence system which Trump authorised for Ukraine during his first term, Russian invasion would have been complete. It may well be that he was not aware as when this happened Zelensky may still have been the comedian acting the part of the president! Very likely, Trump was referring to this when he accused Zelensky of being ungrateful.
Zelensky also should have remembered that he disregarded requests from Trump, after his defeat by Biden, to implicate Biden’s son in some shady deals in Ukraine and that one of the last acts of Biden was to pardon his son and grant immunity to cover the alleged period. Perhaps, actions of the European leaders who embrace him every time they see him, as a long-lost brother, and invitations to address their parliaments has induced an element of the superiority complex in Zelensky that he behaved so combative.
Trump wanted to be the mediator to stop the war and spoke to Putin first. Instead of waiting for Trump to speak to him, egged on by EU leaders Zelensky started criticising Trump for not involving him in the talks. His remark “He should be on our side” demonstrated clearly that Zelensky had not understood the role of a mediator. His lack of political experience was the major reason for the fiasco in the White House and the subsequent actions of Trump clearly showed Zelensky where he stands! PM Starmer and President Macron seem to have given some sensible advice and he seems to be eating humble pie. In the process Trump has ensured that the European nations pay for their defence than piggy-backing on the US, which I am sure would please the American voter. By the way, though Macron talks big about defence France spends less than 2% of GDP. Trump seems vindicated. Of course, Trump could be blamed for being undiplomatic but he can afford to be as he has the upper hand!

Ranil on Al Jazeera
Zelensky has shown what not to do: instead of being diplomatic being aggressive when you need favours! Meanwhile, Ranil has shown what not to do when it comes to TV interviews. God only knows who advised him, and why, for him to go ‘Head to Head’ with Mehdi Hasan on Al-Jazeera. Perhaps, he wanted to broadcast to the world that he was the saviour of Sri Lanka! The experienced politician he is, one would have expected Ranil to realise that he would be questioned about his role in making Sri Lanka bankrupt as well, in addition to raising other issues.
The interview itself was far from head to head; more likely heads to head! It turned out to be an inquisition by Tiger supporters and the only person who spoke sense being Niraj Deva, who demonstrated his maturity by being involved in British and EU politics. The worst was the compere who seems keen to listen his own voice, reminding me of a Sinhala interviewer on a YouTube channel whose interviews I have stopped watching!
Ranil claims, after the interview was broadcast, that it had been heavily edited reduced from a two-hour recording. Surely, despite whatever reason he agreed to, he should have laid ground rules. He could have insisted on unedited broadcast or his approval before broadcast, if it was edited. It was very naïve of Ranil to have walked in to a trap for no gain. Though his performance was not as bad as widely reported, he should have been more composed at the beginning as he turned out to be later. Overall, he gave another opportunity for the Tiger rump and its supporters to bash Sri Lanka, unfortunately.
Medhi Hasan should watch some of David Frost interviews, especially the one with Richard Nixon, and learn how to elicit crucial information in a gentle exploratory manner than shouting with repeated interruptions. He does not seem to think it is necessary to give time for the interviewee to respond to his questions. I will never watch Al-Jazeera’s “Head to Head” again!
Ranil’s best was his parting shot; when asked by Hasan whether he would contest the next presidential election, he said “No, I will retire and watch Al-Jazeera and hope to see you better mannered”!
