The IMD is bolstering बढ़ा रहा है  its observational network with the

1“We have put up six radars in the northwest Himalayas and four more will be installed this year. 

 2 The procurement process is on for eight radars in the northeast Himalayan region.

3 “There are certain gap areas in the rest of the country that will be filled up with 11 radars.

4  The number of radars will increase from 34 at present to 67 by 2025,” the IMD chief said.

Radars are preferred because they have a higher resolution and can provide observations every 10 minutes.

The Ministry of Earth Sciences (MoES) also plans to upgrade its high-performance computing system —

 from a capacity of 10 petaflops currently to 30 petaflops in the next two years —

 which will help assimilate more data into the model that can then be run at higher resolutions.

The lower the range of a weather model, the higher its resolution and the greater the precision. 

At present, the IMD-MoES weather modelling system has a resolution of 12 kilometres. 

The target is to make it six kilometres. 

Similarly, the resolution of the regional modelling system will be improved from three kilometres to one kilometre

1 “A study by the Indian Institute of Tropical Meteorology, MoES says the frequency of mini-cloud bursts (five cm or more rainfall in an hour) is increasing in the Himalayas. And it can also cause damage,”

2 The IMD head explained that climate change has increased the surface air temperature, which in turn has increased the evaporation rate. Since warmer air holds more moisture, it leads to intense rainfall.
