Air masses and fronts:
- Air masses originating from tropical latitudes are warmer, while air masses from the poles are cooler.
-Air masses that form over the ocean have more moisture then those over land.
-Air masses can be identified by the area of origination and the moisture.
1. continental air mass: very cold and dry
maritime tropical air mass: warm and moist
arctic air mass: very cold and dry
Fronts:
- there are four types of fronts
- it's a boundary and it is created when 2 different air masses of different temperatures and humidity collide; this causes a change in weather
- COLD FRONTS: rain occurs, separates fast-moving air, violent weather can occur if there is a significant difference in the two air masses' temperatures.
- WARM FRONTS: occurs when slow moving warm air replaces retreating cold air while this occurs there is light moderate rain, warmer front cause higher humidity and temperatures
- STATIONARY AND OCCLUDED FRONTS: if the air masses aren't moving, a stationary front forms. It's a boundary between nonmoving cold air masses and warm air masses; they do not advance or retreat. Occluded fronts occur when cold fronts take over warm fronts.
