Satellites · Satellite images are used for seeing cloud patterns and movements. · For example, hurricane clouds and movement can be observed using satellite images. Radar · Radar images can be used to detect cloud cover, rainfall or storm location, intensity, and movement, as well as the potential for severe weather (for example, hurricanes or tornadoes).

A front is the boundary separating air masses of different densities Fronts extend both vertically and horizontally in the atmosphere

In U.S., cold fronts usually move from northwest to southeast Air gets drier after a cold front moves through

In U.S., warm fronts usually move from southwest to northeast Air gets more humid after a warm front moves through

Stationary Front: When either a cold or warm front stops moving When the front starts moving again it returns to either being a cold or warm front

High pressure causes air to sink Usually results in several days of clear sunny skies Air rises in low pressure areas and forms water droplets Can results in rain and storms

High pressure systems usually signal more fair weather with winds circulating around the system in a clockwise direction. Low pressure systems with counterclockwise circulating winds often result in rainy and/or stormy weather conditions. LIFT HEAVY
