The barometric pressure in Sullivan, Indiana is constantly changing. It rises and falls throughout the day. This change affects the weather patterns in the area. Shifts in pressure bring different types of weather.
Sullivan is situated in a valley surrounded by rolling hills. The landscape plays a significant role in shaping the atmospheric pressure. The hills block and redirect wind patterns. This, in turn, alters the pressure. The valley also traps cold air, leading to colder temperatures in winter.
The surrounding landscape also influences the precipitation in Sullivan. Moist air from nearby Lake Michigan moves over the hills. As it rises, it cools, and the water vapor condenses, resulting in precipitation. This leads to increased rainfall and snowfall in the area.
