Hi

This is a normal satellite picture and you can't see any sudden temperature changes on those. You see the temperature of the closest cloud, water or ground surface which can be seen by the satellite. Warmest over subtropical waters or hot land in the afternoon, coldest on cloud tops. But these varying temperatures vary with altitude, so what you don't see is a horizontal change in temperature. And BTW, the stories in this forum about temperature changes of 20-30 degrees (what degrees?) horizontally and at short notice are not realistic. We are talking about a few degrees centigrade with a difference in cloud or out of cloud.

The temperature differences met vertically in SEV TURB may be much bigger than those horizontally, just by the up and down of the aircraft. In a cloud, the the horizontal temperature is quite uniform.
