As it occurred within the newest case, the train even then was met with a modest response. The primary distinction between the current and the previous experiments was that whereas the southern State was desperately in want of water to fulfill its ingesting water and farming necessities, Delhi tried its luck with the trials to handle the issue of air pollution.
In January 1970, P. Koteswaram, Director General (DG) of the India Meteorological Department (IMD), (the put up then referred to as Director General of Observatories), dropped the primary trace of experiments in synthetic rain-making, for which he would maintain dialogue with the Tamil Nadu authorities. Koteswaram, who acquired Padma Bhushan (1975) and was the primary Indian to be elected as Vice-President of World Meteorological Organisation throughout 1971-1975, referred to the profitable trials in Delhi, Agra and Jaipur areas within the earlier 10 years by seeding clouds with salt injected from turbines on the bottom.
Earlier, a report in The Hindu dated August 18, 1968 mentioned, the Union Ministry of Food and Agriculture in session with the Council of Scientific and Industrial Research and the IMD had ready a five-year scheme to conduct experiments on an intensive scale, utilizing plane in an acceptable area. The report mentioned the experiments, confirmed a rise in rainfall by about 20% within the focused areas which included, Munnar (Kerala) and Tiruchi (TN).
As the early Seventies weren’t that sort to Tamil Nadu when it comes to rainfall, the federal government confirmed a eager curiosity within the idea of synthetic rain. The Indian Institute of Tropical Meteorology (IITM) did trials in and round Tiruvallur for 3 months from July 1973. But Koteswaram went on report saying no particular conclusion was arrived that the rain that occurred was as a result of seeding of the clouds in view of “inadequate variety of observations and a few sensible difficulties,” this newspaper reported on May 11, 1974.
In the meantime, the Union authorities, on the behest of the Tamil Nadu authorities, had approached a Canadian agency in Mumbai for taking over a venture to induce rain from monsoon clouds over Chennai and the Nilgiris. Giving particulars to this each day on April 30, 1975, the then Chief Secretary of Tamil Nadu, P. Sabananayagam, put the estimated price of the venture at ₹1 crore together with the international change element of ₹ 80 lakh.
About two months later, information was out that the substitute experiments would begin shortly over the catchment areas of water sources of Chennai and the hydel areas of the Nilgiris district. The operation would start after July 12 and proceed until mid-November. A 3-member staff of Americans, consisting of a floor engineer, a pilot and a meteorologist, “would spot the rain-bearing clouds with the assistance of the radar gear on the bottom, fly over the clouds, seed them with chemical substances and make them shed the rain within the catchment areas,” acknowledged a report in The Hindu on July 8, 1975. It added the Americans had performed comparable operations of their nation and in Africa. The venture price was reduce to ₹ 12 lakh, together with ₹ 10 lakh in international change for which the Union authorities had given the clearance.
After the launch of the operations, the catchment areas acquired rainfall. For occasion, Poondi recorded 3.7 cm on July 21. Ok. Chockalingam, then Special Secretary within the State Agriculture division, sounded cautious concerning the one-to-one relationship concerning the experiments and the rainfall, whereas saying the stretch between Poondi and Red Hills too bought rain. After finishing the primary leg of operations on July 29, Fred Clarke, engineer-member of the American staff, claimed about 20% extra precipitation occurred due to the seeding. Chockalingam acknowledged there had been some influx subsequently into the Satyamurti Sagar in Poondi.
In an interplay with journalists in Pune every week later, Y.P. Rao, IMD’s DG, disapproved the claims that “the substitute rain-making experiment was profitable instantly after a single flying into the clouds”. Writing an editorial, The Hindu, on August 13, 1975, acknowledged that “in his (Rao’s) view, such on the spot analysis just isn’t potential and scientific exams have to be carried out over a reasonably lengthy interval earlier than any verdict on the experiment might be pronounced. Yet the difficulty concerned within the Madras [now Chennai] experiment relates primarily to giving reduction to a water-starved place someway or the opposite.”
A fortnight earlier than the dismissal of his authorities in January 1976, the then Chief Minister M. Karunanidhi, defined to journalists concerning the failure of northeast monsoon within the composite districts of Madurai, Ramanathapuram and Tirunelveli districts. The State authorities was considering approaching the American firm for cloud seeding operations over the districts.
Again, within the early Nineteen Eighties, the spell of drought hit the State, particularly Madras and surrounding areas. This time, the regime was headed by M.G. Ramachandran with Chockalingam because the Chief Secretary. In July 1983, the operation was carried out by a four-member American staff, led by Thomas Henderson. A “reasonable rainfall” was recorded by Poondi. The experiments went on until October, on the completion of which the State authorities mentioned the train had price ₹26 lakh, in response to a report of this newspaper on November 18, 1983. Eight months later, the federal government sanctioned ₹62 lakh for cloud-seeding operations [which began in July 1984] over the town’s reservoirs. As the state of affairs was grim, the authorities went to the extent of enlisting the providers of the violin exponent Kunnakudi Vaidyanathan, who stuffed the air on the shores of Red Hills tank with the strains of Amritavarshini [a raga said to have been composed by Muthuswami Dikshithar], imploring the rain gods to reply.
The State authorities’s buy of an plane in 1983 for the aim got here in for criticism of the Comptroller and Auditor General, whose report was tabled on the ground of the Assembly in November 1987. “The State Government not solely didn’t undertake the same old tender process but additionally paid a value far in extra of the one prompt by Hindustan Aeronautics Limited (HAL) which inspected the second-hand plane,” reported this newspaper on November 10, 1987. Six years later, one other report acknowledged that “the plane remained idle for need of spares for someday and needed to be despatched for obligatory overhauling at HAL at a value of practically ₹13 lakh and at last needed to be disposed of.”
In 1993, when Chennai was within the grip of yet one more spell of water scarcity, the trials have been achieved. But, by then, a consensus had emerged among the many scientific neighborhood that no space bought any greater than 20% of rainfall over and above the traditional. Ten years later, the then Chief Minister Jayalalithaa made an announcement however the authorities didn’t translate her determination into motion in view of the absence of “conducive circumstances.”
The addition of Krishna water and Veeranam tank as sources to Chennai water provide coupled with many seawater desalination crops has made the town’s water provide place much better than what it was previously, rendering cloud-seeding operations out of anybody’s thought at the same time as an choice to sort out the scarcity of ingesting water.
