Explanation:
Low-pressure systems in the Northern Hemisphere have counterclockwise wind circulation due to the Coriolis effect. They are associated with rising air, cloud formation, and precipitation.
Explanation:
The troposphere is characterized by decreasing temperature with altitude (normal lapse rate) due to adiabatic cooling, and it contains most of the weather phenomena.
