- •
Microwave radiometric observations are used to nowcast convective rain events.
- •
Brightness temperatures of 22.24 GHz and LI show definite change before convection.
- •
These two parameters indicate impending convective growth much before rain.
- •
The prediction technique generates alarm 75 min before rain for 80% of cases.
