Satellite-derived three-hourly IR temperatures for the
past four days. Green shading indicates warmer cloud-top temperatures and possible
stratiform precipitation and red shading indicates cold cloud-top temperatures and
possible convective activity. IR temperatures are obtained from a merge of GOES 8,
METEOSAT 7, and METEOSAT 5 satellites, and have latitudinally and seasonally dependent
zenith angle corrections. |
