characteristics and weather of warm fronts at the surface and aloft.
OUTLINE Surface characteristics Weather Upper air characteristics Warm fronts aloft THE WARM FRONT A warm front is the line of discontinuity where the forward edge of an advancing mass of relatively warm air is replacing a retreat-ing relatively colder air mass. The slope of the warm front is usually between 1:100 and 1:300, with occasional fronts with lesser slopes. Therefore, warm fronts have characteristically shallow slopes caused by the effect of surface friction that retards the frontal movement near the ground. Learning Objective: Describe the characteristics and weather of warm fronts at the surface and aloft. |
