A deep borehole up to a distance of three kms would be drilled in the Laxmi Basin, Arabian Sea, in 2015 to get information about the origin of the monsoon, said Dr Shailesh Nayak, secretary, Ministry of Earth Sciences. He was speaking at the at the inaugural function of four-day International Tropical Meteorology Symposium on Monsoons-Observations, Prediction and Simulation (MOPS) organized by the SRM University Kattankulathur.
“Under the Indian Ocean Deep Drilling Program, we will be drilling a deep borehole that is expected to provide information about the origin of the monsoon as well as its variability in the past,’’ he said.
Since the variability of Indian Summer Monsoons was critical to agriculture, water resources and economy of the country, he said that understanding the variability of monsoon and prediction was vital for the well-being of the population of India. “We have made significant progress in improving the five-day forecast, the accuracy of which has been around 70-75 per cent,” he said.
‘’There was lot of media attention about Uttarakhand floods. The specific forecast for Kedarnath, Badrinath, Joshimath, Gangotri and Jamanotri was provided to all concerned before three days,’’ he pointed out. This was apart from the good forcast of Phailin Cyclone, Mahasen, Helen, Lehar and Madi cyclones
He also added that cyclone track, landfall, associated rainfall and storm surge prediction has been improved considerably.
