I can help with that! An **air mass** is a large body of air with generally uniform temperature and humidity. Air masses are classified based on their source region and can cover vast areas of the Earth's surface. They play a significant role in shaping weather patterns when they move into a region with different characteristics.
For example, a continental polar air mass originating over northern Canada would be cold and dry, while a maritime tropical air mass from the Gulf of Mexico would be warm and moist. When these air masses collide, it can lead to the formation of fronts and various weather phenomena like thunderstorms or snowstorms.
Understanding air masses is essential in meteorology as it helps predict weather changes and patterns based on the characteristics of the air masses present in a region.
