3 Main Types of Clouds • Cirrus – high level clouds, high altitude – Isolated clouds – stable – no rain – Dense clouds – often indicate a storm • Stratus – low - level – layered clouds that usually bring a drizzle • Cumulus– neutral weather clouds • Video

Cloud Prefixes • Nimbo & nimbus– precipitating cloud – Ex: Cumulonimbus & Nimbostratus •

Cloud Prefixes • Nimbo & nimbus– precipitating cloud – Ex: Cumulonimbus & Nimbostratus • Alto – means tall mid level clouds – Ex: Altostratus & Altocumulus • Cirro – means high – Ex: Cirrostratus & Cirrocumulus

Clouds that produce Weather • Cumulonimbus – heavy dense clouds produce thunderstorms and hail

Clouds that produce Weather • Cumulonimbus – heavy dense clouds produce thunderstorms and hail • Nimbostratus – continuous rain cloud – blots out the sun

Rotational Hurricane • Coriolis Effect - The rotation of the Earth causes an interesting phenomena on free moving objects on the Earth. Objects in the Northern Hemisphere are deflected to the right, while objects in the Southern Hemisphere are deflected to the left. • The coriolis effect thus tries to force winds to shift towards the right or left.

Traveling Air Masses • Air mass in a valley travels up a mountainside –

Traveling Air Masses • Air mass in a valley travels up a mountainside – Caused by solar energy warming the air after it is re-radiated from the ground

What does Ozone do to temperature? • As you increase altitude in the Stratosphere the temperature increases because of Ozone
