UPSC Notes

A Doppler Weather Radar (DWR) is a meteorological radar used to detect precipitation and study atmospheric conditions. It uses the Doppler effect to estimate the movement of precipitation particles.

Key Pointers

  • Used for weather monitoring and forecasting.

  • Detects rainfall, storms and precipitation systems.

  • Doppler effect helps estimate radial velocity of targets.

  • Can provide information about:

    • Rain intensity

    • Wind movement

    • Storm structure

    • Severe weather

  • Useful for forecasting:

    • Cyclones

    • Thunderstorms

    • Heavy rainfall

    • Hailstorms

  • Important for early warning and disaster management.

Prelims Focus: DWR → Doppler effect → precipitation → radial velocity → severe-weather warning.
