Atmosphere & Weather Intro

Sunlight enters the atmosphere, is converted to infrared radiation and is trapped by gasses in air

• Ozone layer depletion
• Ultraviolet radiation absorption
• Temperature Inversion

• Greenhouse effect

Cold air moves in forcing warm air up

• Cold front

• Warm front

• Stationary front

• Occluded front
