Extreme weather situations such as thunderstorms and lightning can arise within minutes. If we knew more about the local state of the atmosphere, the genesis of extreme weather could be better forecast. Meteosat Second Generation is equipped with instruments suited for higher resolution and frequent imaging in 12 channels. It observes the processes in the atmosphere in shorter sequences and even distinguishes between water and ice crystal clouds. This data input is essential in the provision of more accurate local weather forecasts.
