ABOUT THIS ISSUE n the past decade, many I countries of Asia have been repeatedly struck by extreme heat and heat waves. Many scientists have attributed this trend of rising heat wave incidents to climate change.

This include a) strengthening of observational network (over land, sea and air); b) installing the state-of-the-art weather and climate prediction systems based on coupled models; c) acquiring faster computing resources; and d) investing in human resources development. Ministry has the computing capacity of about 8.0 petaflop, which is the best in the country and fourth best among the weather prediction centers in the world. The dramatic reduction in the lives lost due to high impact weather events in the last few years has been largely attributed to the significant increase in accuracy of weather http://citiscope.org/story/2017/lessons-and-challenges-indian-cities-step-planning-heat-waves October 2018 southasiadisasters.net 3 appreciable improvements during 2007-13 for 24, 48 and 72 Nina and climate prediction during the past 4 years.
