Study Notes
- Air masses have consistent temperatures and water content.
- Polar air masses are cold and form near the Earth's poles.
- Tropical air masses are warm and form near the Earth's equator.
- Maritime air masses form over oceans and contain moisture.
- Continental air masses form over land and have lower water content.
- Air masses form by remaining stationary over a geographical area until the water molecules and heat become evenly distributed.
- Weather fronts are associated with low pressure systems, where less dense warmer air rises above denser cooler air.
- Moisture in air masses can lead to cloud condensation and precipitation.
- Front types include warm, cold, stationary, and occluded, each resulting in different weather patterns.
Stationary Fronts
- Stationary fronts occur when warmer and cooler air masses move towards each other at the same speed or not at all.
- The boundary remains stationary over its geographical location
- Represented on weather maps as a line with blue arrows on one side and red half-circles on the other.
- Associated with days of rain and clouds due to its stationary nature, assuming moisture is available.
- End when moisture is depleted, or one air mass begins to advance.
Cold Fronts
- Cold fronts occur when a cooler air mass advances into a warmer air mass.
- Represented on a weather map as a blue line with blue arrows or triangles pointing in the direction of movement.
- Typically associated with cumulus cloud formations and thunderstorms.
- Warmer air is forced upward, causing moisture condensation in tall clouds.
- Can lead to cumulonimbus clouds, resulting in intense thunderstorms, hailstorms, and squalls.
Warm Fronts
- Warm fronts occur when a warmer air mass advances into a cooler air mass.
- Represented on a weather map with a red line with red half-circles pointing in the direction of movement.
- Typically associated with stratus clouds or fog due to the gradual rising of warm air over the cooler air mass.
- Usually results in drizzles or steady, gentle rain.
Occluded Fronts
- Occluded fronts occur when a cold front overtakes a warm front.
- Represented on a weather map as a purple line with alternating purple arrows and half circles.
- Associated with large amounts of precipitation.
- The cold front forces the warm air upward, causing condensation and cloud formation.
- Weather patterns resemble a cold front behind the occluded front and a warm front ahead of it.
U.S. Weather Fronts
- Warm fronts typically form in the southern regions of the United States.
- Cold fronts typically form in the mid and heart lands, advancing further south in winter.
- Stationary fronts can form anywhere along these regions.
- Occluded fronts are more likely to form in the mid-United States due to the collision of cold fronts from the northwest and northeast.
