India currently has 47 Doppler Weather Radars (DWRs) deployed across the country for weather monitoring and forecasting, as informed by the Ministry of Earth Sciences.

🌧️ What is Doppler Weather Radar?
A specialised radar that uses the Doppler Effect to measure:
• Position of rain and clouds
• Speed & direction of storms
• Wind movement inside weather systems

⚙️ How DWR Works
1️⃣ Radar emits radio waves
2️⃣ Waves hit raindrops/ice particles
3️⃣ Signals scatter back
4️⃣ Time delay → distance
5️⃣ Doppler shift → speed & direction
6️⃣ Stronger signal → higher rainfall intensity

⚡ Unlike conventional radars, DWR provides wind speed and wind direction data, essential for cyclone & thunderstorm forecasting.
