Document Summary
Weather: air masses, atmospheric lifting mechanisms, midlatitude cyclonic systems, violent weather. Air mass modification lake effects: air previous sitting on great lakes moves over land masses, cools and precipitates, when moving air mass across land masses they can change their characteristics. Not nearly as rapid as cold front. Warm air moves up and over cold air. Life cycle of a midlatitude cyclone: cyclogenesis. Starts with a low-pressure system: open stage. Warm and cold fronts are separated: occluded stage. Warm front has caught up to the cold front. Cools over time and system disappears: storm tracks. Midlatitude cyclone: spirals into a low-pressure system (counter clockwise) Tornadoes: low pressure systems, high velocity, strong winds, tornado alley (air moving over the rocky mountains, general occur when the ground begins to heat up (apr-jun, incredible damaging. Tropical cyclones: do(cid:374)"t co(cid:374)fuse with (cid:373)idlatitude cyclo(cid:374)es, different names for them: hurricanes (north america), typhoons (japan),
