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...

WX 201 - Exam 2 Chapter 6-10 Questions and Answers The elevation where clouds form is called ____ level. condensation If the environmental lapse rate is 5 ° C per 1,000 m and the temperature at Earth's surface is 25 ° C, then the air temperature at 2,000 m above the ground is 15°C. What transfers heat upward into the atmosphere? thermals Just above cumulus clouds, you would expect to find a stable layer. If an air parcel is given a small push upward and it falls back...
