PPL – Weather Questions and Answers Graded A+ General characteristics of air flows around high/low pressure systems in the Northern Hemisphere Low Pressure - inward, upward, and counterclockwise High Pressure - outward, downward, and clockwise What is a trough? An elongated area of relatively low atmospheric pressure. At the surface when air converges into a low, it cannot go outward against the pressure gradient, nor can it go downward into the ground; it must go upward. Therefor...

What is the pressure gradient defined as? - -The rate of pressure change in a direction perpendicular to the isobars What type of vertical atmospheric circulation is associated with a low-pressure system? - Air will ascend (insufficient pressure to keep air at the surface) and try to converge at the center of the lowpressure, which also produces wind Define Atmospheric Pressure (Barometric Pressure) - -Pressure exerted on a surface by the atmosphere due to the weight of the column of air di...
