Air Masses ► An air mass is a defined as a large body of air with very similar characteristics. ► Air masses are generally defined by temperature and moisture ► Air masses are named based on the source region of the air mass itself
![Types of Air Masses Continental Polar cold and dry Continental Tropical warm Types of Air Masses ► Continental Polar, “cold and dry” ► Continental Tropical, “warm](https://slidetodoc.com/presentation_image_h/d6d6c946449e86fad87eb539677bac59/image-3.jpg)
Types of Air Masses ► Continental Polar, “cold and dry” ► Continental Tropical, “warm and dry” ► Maritime Polar, “cold and damp” ► Maritime Tropical, “warm and humid” ► Arctic, “very cold” § Originates closer to the Poles over land -locked regions. § Originates closer to the Tropics over land-locked regions. § Originates closer to the Poles over water. § Originates closer to the Tropics over water. § Originates in the very cold land-locked areas

What is a Front? ► The boundary where two air masses meet. ► Commonly associated with. . § Moisture gradient § Temperature gradient § Wind shift

Types of Fronts ► Cold ► Warm ► Stationary ► Occluded § Noted by cold air advancing and displacing warmer air that exists. § Noted by cold air retreating from an area. § While differing air masses exist along a boundary, little movement is analyzed of the air masses. § A complicated process where the surface low becomes completely surrounded by cooler/cold air. Occlusion processes can be a “cool type” or “cold type” (more later. )

Cold Front ► Marked on a map with a blue line and blue triangles pointing towards the warm air. ► Associated with cumulus & cumulonimbus clouds ahead of the front in the warm air, producing showers and thunderstorms.

Warm Front ► Marked on a map by a red line with red semi-circles pointed towards the cool air (in the direction the warm air is retreating to. ) ► Generally associated with stratus type clouds, overcast skies, fog, and general rain or snow.

Stationary Front ► Marked by alternating blue lines & blue triangles (pointed in the direction of the warmer air) and red lines & red semi-circles (pointed in the direction of the cooler air) ► Usually noted as *quasi*-stationary as it is rarely ever completely stationary. It tends to meander a bit.
