The term maritime tropical (mT) refers to a warm, moist air mass that originates over the tropical oceans. This air mass is characterized by its high temperatures and significant humidity, which are both crucial for weather patterns, especially when it moves over land and interacts with cooler air.

Maritime tropical air masses are formed in regions where the sea surface temperatures are warm, usually in the tropics, allowing them to gather moisture as they form. When these air masses migrate towards land, they can lead to the development of various weather phenomena, including thunderstorms and heavy rainfall, particularly in the summer months.

The characteristics of maritime tropical air masses play a vital role in the climate of adjacent coastal regions, as well as influencing larger meteorological events. Understanding these air masses is important for predicting weather patterns and preparing for changes in atmospheric conditions.
