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...
