Traveling Cyclones and Anticyclones Cyclonic storm : intense weather disturbance within a moving cyclone generating strong winds, cloudiness, and precipitation Three types of cyclones (low pressure) 1. Wave cyclone midlatitudes, Arctic, Antarctic zones 2. Tropical cyclone tropical and subtropical zones 3. Tornado An anticyclone (high pressure) is a fair-weather system. Mid-latitude cyclones ** Storms, neither tropical nor hurricanes, form along a front in the middle and high latitudes. ** Synoptic scale low pressure system that has cyclonic (counter-clockwise in the northern hemisphere) flow. ** Characterized by the presence of frontal boundaries. ** It travels great distances bringing precipitation and sometimes severe weather

Unformatted text preview: to wide areas. Polar Front Theory- provided insight into the development, movement, and dissipation of middle latitude cyclones. Cyclogenesis Life cycle of a typical mid-latitude cyclone (wave cyclone). They are guided along a path reflecting the configuration and speed of the upper air westerlies or the jet stream. A general west-to-east pattern prevails. Life cycle based on polar front theory. Stage 1- Trough of low pressure with high pressure on both sides (of the Polar Front) . The two anticylones come into contact on the polar front. One contains a cold dry air mass, and the other a warm, moist maritime air mass....
