warm pool

(Also called warm drop, warm-air drop.) A region, or "pool," of relatively warm air surrounded by colder air; the opposite of a cold pool.

The common application of this term is to warm air of appreciable vertical extent isolated in high latitudes when a cut-off high is formed. Warm pools can be identified as thickness maxima on thickness charts.
