A tropical cyclonic storm with sustained winds of 119 km/h (74 mph) or greater. A periodic change in the state of Earth’s climate caused by the slackening and temporary reversal of the Pacific equatorial trade winds and increased sea surface temperatures off coastal Peru. A thunderstorm with a rotating cylindrical updraft that usually produces severe weather. A cumulonimbus cloud that produces lightning and thunder. An electrical discharge produced by thunderstorms. A typeof midlatitude cyclone that brings blizzard- A type of thunderstorm that forms under conditions of moderate wind shear, is organized in squall lines or clusters, and often produces severe weather. Heavy snowfall that results as cold air moves overlarge, relatively warm bodies of water, such as the Great Lakes. A thunderstorm that produces eitherhail sized 2.54 cm (1 in) in diameter, a tornado, or wind gusts of 93 km/h (58 mph) or greater. A system used to rank tornado strength based on damage done to the landscape. A region where cold air advances on relatively warm air; sometimes associated with severe weather. A glassy hollow tube formed where lightning strikes sand. A rise in sea level caused by the strong winds and low atmospheric pressure of a hurricane. An alert issued by the National Weather service when conditions are favorable for tornadic thunderstorms. A line of multicell thunderstorm cells that typically forms along a cold front. An acoustic shock wave produced when lightning rapidly heats and expands the air around it. A region where warm air advances on and flows over cooler,heavier air; not associated with severe weather. (or extratropical cyclone) A large cyclonic storm at midlatitudes. A tropical cyclonic storm with sustained winds between 63 and 118 km/h (39 to 73 mph). A name used for tropical cyclones in Southeast Asia. A violently rotating column of air that descends from a cumulonimbus cloud and touches ground. Changes in wind speed and direction with altitude. A type of thunderstorm that is short- A large region of air that is uniform in temperature and humidity. The rotating cylindrical updraft within a supercell thunderstorm.
