A derecho (pronounced similar to deh-REY-cho in English, or pronounced phonetically as ) is a widespread, long-lived wind storm associated with a band of rapidly moving showers or thunderstorms variously known as a squall line, bow echo, or quasi-linear convective system.
Rear inflow jet â the teeth of the derecho. Under the right set of atmospheric conditions, the cold pool develops a feature called a rear inflow jet. The rear inflow jet is what gives the derecho its punch. It's a low-level jet of air that moves from the back of the derecho to the front. The jet can exceed 100 MPH by the time it reaches the front of the squall line and dives down to the surface.
