Cyclone Forecasting
-
The IMD has considerably increased its efforts in recent years in the areas of Tropical Cyclone forecasting and verification.
-
Many facilities have been developed to enable a detailed assessment of the global model’s performance in the forecasting of TCs as well as operational TC forecast performance.
-
Three major factors that have enhanced IMD’s capabilities in cyclone forecasting are
-
Doppler weather radars
-
International collaborations with Japanese meteorological agency, US National Hurricane Centre etc.
-
Increased deployment of ocean-buoys that help track variations in sea surface characteristics.
-
Doppler weather radar
-
The Doppler Weather Radar (DWR) provides advance information, enhancing the lead-time so essential for saving lives and property, in the event of natural disaster associated with severe weather.
-
Though the conventional radars are able to track and predict cyclones, the DWR provides detailed information on storm’s internal wind flow and structure.
-
The severity of the weather systems can thus be quantitatively estimated more accurately than ever before and more precise advance warnings can be generated for saving human lives and property.
-
There is a network of 27 doppler weather radars (DWR) in India with 12 of them being on the coast.
