Belleville, Arkansas has changing air pressure because of its location. The Gulf of Mexico's warm air and the Rocky Mountains' cool air clash, making the air pressure go up and down. The Ozark Mountains surrounding Belleville block some air, making it harder for air to move, which changes the pressure. In spring and fall, the air is not too hot or cold, so the pressure is more stable. In summer, the hot air expands, making the pressure lower. In winter, the cold air is denser, making the pressure higher. Belleville has a humid subtropical climate, which means it has hot summers and mild winters, causing air pressure to change with the seasons.
