Heat Bursts
A special, and much rarer, kind of downburst is a heat burst, which results from precipitation-evaporated air compressionally heating as it descends from very high altitude, usually on the backside of a dying squall line or outflow boundary. Heat bursts are chiefly a nocturnal occurrence, can produce winds of up to 100 mph (160 km/h), are characterized by exceptionally dry air, and can suddenly raise the surface temperature to 100 °F (38 °C) or more, sometimes persisting for several hours.

Famous quotes containing the words heat and/or bursts:
“Nowadays men cannot love seven night but they must have all their desires: that love may not endure by reason; for where they be soon accorded and hasty, heat soon it cooleth. Right so fareth love nowadays, soon hot soon cold: this is no stability. But the old love was not so.”
—Thomas Malory (c. 1430–1471)
“Cracks and reforms and bursts in the violet air
Falling towers
Jerusalem Athens Alexandria
Vienna London”
—T.S. (Thomas Stearns)
