Clouds

Cloud terms

Alto – tall

Strato – spread out

Nimbus – precipitation

Cumulus – heap

Cumulonimbus - column of rain

Cirrus - curl, curly hair

Types of weather masses

- cold -warm-stationary-occluded

Cold front

Forms when a cold air mass pushes under a warm air mass

warm air risesthunderheads, cool fair

weather

Warm Front

Forms when a moist, warm air mass comes up and over a cold air mass

cloudy, little rain/snow & warmer weather

Stationary front

Forms when warm and cold air meet and neither air mass has the force to move the other – stand still

clouds, fog, could rain/snow

Usually many days of clouds and precipitation

Occluded Fronts

Forms when warm air mass gets stuck between 2 cold air masses. The warm air mass rises as the cool air masses push and meet in the middle

temp drops, heavy winds & precip.
