Weather patterns in Louisiana bring changes in barometric pressure, making it rise and fall. This affects the atmosphere, causing air to expand or contract.
Louisiana's low elevation near the Mississippi River and surrounding hills influence atmospheric pressure. The landscape allows air to move freely, making pressure changes more noticeable.
In winter, pressure is usually higher, bringing drier air. In summer, pressure is lower, bringing more humid air. This leads to common weather patterns like cold fronts and thunderstorms.
