Document Summary

Chapter 10 (continued part 3): thunderstorms and tornadoes. Supercell thunderstorms: made of a single, very powerful cell, vertical heights extend to 20km(65,000ft, storm persists for many hours, diameters reach 12-30 miles across, rotation occurs in the updraft due to strong vertical wind shear. Downbursts: a localized downdraft that hits the ground and spread horizontally in a radial burst of wind, much like water pouring from a tap and striking the sink below. Microbursts: a downbursts with winds that extend only 2. 5 miles or less across. The downdrafts are accelerated by a great deal of evaporative cooling (cold air, (cid:373)ore de(cid:374)se, will (cid:862)fall(cid:863) faster). This can cause winds in excess of 100mph. Multiple thunderstorms in a region: mesoscale convective complex (mcc): many individual thunderstorms organized into a large oval to circular cluster. This usually occurs over the plaints where a group of afternoon air-mass thunderstorms are enhanced by a strong low-level of very warm, moist air.
