IMD to install DRS in NE region

In a bid to accurately predict forecasts of rainfall intensity, direction of storms and even hailstorms the Indian Meteorological Department will be installing eight doppler radar systems in the Northeast.
The radar systems will be installed at Jorhat, Guwahati, Dhubri and Tezpur, Lengpui and one each in three other state capitals– Imphal, Kohima and Itanagar in the current financial year.
The purpose of a doppler radar is to identify the presence, speed, distance or direction of objects. It sends out radio waves, which reflect off surfaces and return to be detected by the same device. Northeast which is mainly covered by hills and forests poses a barrier in the weather forecast, however, the installation of the doppler radars will eliminate this impediment and the weather department will be able to accurately predict forecasts.
Head of the Regional Meteorological Centre of IMD here in Guwahati, KN Mohan told TOI that the barriers created by the hills in the North Eastern states would not hinder weather forecasts after these radars are installed and start functioning.
“Each of the new radars will cover a radius of 150 km and will be able to give proper updates on weather concentration within this range. With all the eight radars, the human habitations in the entire northeast will be covered. Most importantly, hailstorms, which are a major cause of crop damage over vast areas, will also be predicted now,” said Mohan.
He said that these radars are also capable of predicting the probable direction of a storm, which claimed several human lives in Assam this month. “These radars will assess the amount of water inside clouds. Issuing forecasts of rainfall with its probable intensity will be much more accurate,” he added.
Moreover, these radars can be shifted from one place to another to give timely updates in case of more adverse weather conditions in a particular zone. They can be run on generators. Each radar costs Rs 5 to 6 crore and the installation of these in Phase I will be completed by December this year, Mohan said.
He added that installation of all the eight radars will be completed by March 31 next year. RMC, Guwahati had sent the proposal to upgrade the weather forecasting radar system to its headquarters in 2018 for the region, which is hit by incessant rain, floods and landslides every year.
