UMM discipline’s thermal imager: clouds of a warm front

Layer of warm clouds, looking west

High-contrast palette

View west. Note layer of warm clouds

Stratocumulus transporting convective heat upwards, underneath a layer

of altostratus

Note the higher temperatures on cloud bottoms, indicating liquid rather than

ice crystals

Altostratus is colder than -22°F.

Warmer stratocumulus growing underneath altostratus

Convective layer of stratocumulus. Mixing and heat transport is visible

Note the apparent layer of very warm air close to the ground. The boundary marks

A temperature inversion under the limited convective layer.
