Fronts and Clouds I can predict the cloud type that will results from various types of fronts.

Cold Front Cold air mass overtakes a warm air mass Move very quickly because cold air is very dense Associated with cumulus & cumulonimbus clouds ahead of the front in the warm air, producing heavy showers and thunderstorms. Fast, gusty winds Areas of low pressure Followed by cooler temperatures

Warm Front A warm front overtakes a cold front Generally associated with stratus type clouds that are high in the atmosphere Clear weather at first, but rain and thunderstorms may follow Warm fronts have higher air pressure but are followed by warmer temperatures

Stationary Front Blue triangles point toward warm air Red circles point toward cold air Warm front and cold front meet, and neither overpowers the other Marked by longer periods of rain, snow, or other precipitation Wind often blows parallel to front rather than against it Often occur in low pressure areas

Occluded Front Two cold air masses overtake one warm air mass, pushing it up in between them Usually form in low pressure areas Cause extreme weather including a lot of precipitation and bring cumulonimbus or nimbostratus clouds Wind often changes directions
