What’s Day Convective Storm RGB? R : B08(WV6.2) – B10(W3 7.3) Range : -35～5 [K]　Gamma : 1.0 G : B07(I4 3.9)-B13 (IR10.8) Range : -5～60 [K]　Gamma : 0.5 B : B05(NIR1.6)-B03(VIS0.6) Range : -75～25 [%]　Gamma : 1.0

Interpretation of Colors for “Day Convective Storms” Deep precipitating cloud (precip. not necessarily reaching the ground) High level Cloud Large ice particles Deep precipitating cloud (Cb cloud with strong updrafts and severe weather)* High level Cloud Small ice particles *or thick, high-level lee cloudiness with small ice particles Thin Cirrus cloud Large ice particles Thin Cirrus cloud Small ice particles Ocean Land Note: Based on SEVIRI/EUMETSAT interpretation
