Cold pool
In
evaporates during intense precipitation e.g. underneath a thunderstorm cloud. Typically, CPs spread at 10 m/s and last 2–3 hours.[1]
Characteristics
CPs spread radially away from the rain event along the surface as a moving
air temperature. In large-eddy simulations, they reach 10 km in radius, whereas, in reality, they can become as large as 50–100 km in radius.[2] Collisions between multiple CPs can trigger the formation of a new thunderstorm event, and thereby form a new CP.[3]
