The weather in Jasper, Alabama, makes the barometric pressure rise and fall. This happens because of the movement of high and low-pressure systems in the atmosphere. When a low-pressure system moves in, the pressure drops. When a high-pressure system comes, the pressure rises.
Jasper's elevation, 484 feet above sea level, and surrounding mountains affect the atmospheric pressure. The mountains block or redirect winds, causing pressure changes. The valley shape of Jasper also helps trap air, making pressure changes more noticeable.
During the summer, the pressure is usually higher in Jasper due to high-pressure systems. In the winter, low-pressure systems bring lower pressure. In the spring and fall, pressure changes are more frequent due to the clash of warm and cool air.
Jasper has a humid subtropical climate, which means it has hot summers and mild winters. This leads to bigger pressure fluctuations between seasons, making the weather feel more changeable.
