What factor contributes to the humidity levels in Mississippi?

The proximity to the Gulf of Mexico is a significant contributor to the humidity levels in Mississippi. The Gulf of Mexico is a warm body of water that evaporates moisture into the atmosphere. This moisture-laden air is often transported over the state, leading to higher humidity levels. As warm, moist air moves inland, it can create conditions typical of humid subtropical climates, characterized by hot, steamy summers and milder winters.

In contrast, high elevation tends to lead to drier conditions as cooler air can hold less moisture. Lack of vegetation can also result in lower humidity since plants contribute to moisture through a process called transpiration, where they release water vapor. Cold ocean currents, while they may lower temperatures, generally do not contribute to increased humidity and can promote drier air masses along coastal regions. Therefore, proximity to the Gulf of Mexico stands out as the primary factor influencing humidity levels in Mississippi.
