NEW DELHI, FEB. 1. Could the tsunami that hit the Indian coast impact global climate? Scientists at ISRO have found that the temperature over a vast stretch of the Indian Ocean had cooled significantly around the same time the tsunami struck, raising the question whether it could have a cascading impact on the atmosphere and consequently the climate across the world. Speaking to The Hindu , Vijay K. Agarwal of ISRO's Space Application Centre in Ahmedabad, said data collected by a satellite operated by the U.S. and Japan, which were consequently corroborated by information from a data buoy on the surface of the Indian Ocean, have shown that the sea surface temperatures had come down by between one and 2.5 degree Celsius around the same time the tsunami struck. The temperature change was found over a large block of the Indian Ocean from the central Bay of Bengal to the Equator, which would be about 200 million sq.km. The anomaly had persisted for about a week.
Wind speed doubled
The scientists at SAC, he said, have also found that the wind speed on the surface of the Indian Ocean had doubled from 20 km to 40 km an hour around the same time as the tsunami waves sped across the sea. The findings, however, need to be further analysed to know whether the cooling of the sea surface and doubling of the wind speed had been caused by the tsunami or whether any other factor was involved, he said. "... The findings are interesting as this is for the first time there has been a report of any change in temperature or wind speed about the same time as a tsunami anywhere in the world.''
