Subject: Physical Geography Session: Chapter 7 - Storms at 04:58 PM Storms temporary and limited as compared to broad scale pressure and wind systems • discussion about storms includes • air masses • fronts • atmospheric disturbances - major and minor air mass - contains uniform temperature and humidity characteristics • fronts - boundaries between unlike air masses • Formation of Air Masses • topographically uniform area • surface conditions transfer to overlying air • moisture content - maritime (high), continental (low) • Temperature - tropical, polar, or artic • continental arctic (cA), continental polar (cP), maritime polar (mP), contiental tropical (cT),

Unformatted text preview: maritime tropical (mT) • Front - transition zone between two air masses of different temperature and moisture content (their densities are different) • locating fronts - criteria • sharp temperature changes - warm air front, then cold air front • sharp dew point changes • wind shifts • pressure changes • presence of clouds and precipitation • four types of fronts • warm front - stratiform clouds, long duration, light precipiations, gentle frontal slope, during summer can get storms, slowly rises over cooler air...
