PPT-Warm, Occluded, and Stationary Fronts

Warm Fronts occurs when a warm air mass slides over a cold air mass Relatively stable Moves slower than a cold front Long transition from cold air to warm air warm air moves slowly Temperature gradually rises. and fronts.

Definition. Weather front – The area where two air masses meet and do not mix.. Front and Weather. Different types of fronts produce different patterns of weather. . There are four types of weather fronts:. Lab. Fronts!. Fronts!. What are fronts?. A narrow transition zone, or boundary, between differing synoptic scale air masses whose primary discontinuity is density. Fronts highlight . baroclinic. zones, where temperature advection and atmospheric energy is at work. We will go over how to upload your file into canvas together.. Wanted Poster Requirements.
