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....
