Document Summary
Weather is affected by temperature, pressure, humidity. cloudiness, and wind: climate is what we expect but weather is what we get, weather can change due to the air masses. Front: boundary between air masses that differ in temp. and moisture. Warm front: boundary where a warmer mass replaces a mass of colder, drier air. Cold front: cold, dry air gets replaced by warm, moist air. High-pressure systems: contains air that move outwards from the centre of high pressure as it descends. Low-pressure system: air moves towards the low atmospheric pressure 2 the center of the system and rises upwards (air expands and cools) Thermal inversion: the normal direction of the movement of air is switched: the cooler air is now @ the bottom while the hotter air is at the top so it is able to re- sist vertical mixing.
