India has been designated as a nodal centre for preparing flash-flood forecasts by the World Meteorological Organization (WMO).
According to an official release, means India will have to develop a customised model that can issue advance warning of floods in Vietnam, Sri Lanka, Myanmar and Thailand.
Speaking on the eve of the Earth Sciences Foundation Day, Dr. Rajeevan said the IMD would be working to customise a weather model, developed by the United States and donated to the WMO, to warn of flash floods at least six hours in advance. A test version of this, according to Dr. Rajeevan, was being tried out by the IMD, and that was able to give a flood warning about an hour in advance. Using a combination of satellite mapping and ground-based observation, this system — called the Flash Flood Guidance System — aims to provide forecasts six hours in advance.
Like India, several southeast Asian countries depend on the monsoon and are prone to its vagaries. The proposed model would provide forecasts by computing the likelihood of rainfall and the soil moisture levels to warn of possible floods, he said. Though Pakistan was among the list of countries that would benefit from the forecast, it had refused to participate in the scheme, Dr. Rajeevan added
