डॉप्लर रडार

डॉप्लर रडार क्या है?

Doppler radar measures the frequency shift of returned microwave pulses to determine the velocity of rain droplets. This reveals wind patterns inside storms, including rotation (potential tornadoes), convergence (strengthening updrafts) and divergence (downdrafts). Dual-polarization Doppler radar can also distinguish rain from hail, snow and debris. Most Southeast Asian national weather services operate Doppler radar networks.
