Document Summary
Weather refers to the state of the atmosphere at one location and at one time o. Climate considers the average temperature, moisture, precipitation, and winds for a broader region over longer periods of time. These masses are characterized by its temperature and moisture characteristics. Source regions of air masses: air masses pick up their characteristics in source regions, where the air moves more slowly or stagnates, air masses are classified by the latitude and surface type of their source regions. It holds less water vapor than the maritime tropical air masses, so the mp air mass yields only moderate precipitation. Much of this precipitation occurs over mountain ranges on the western coasts of continents. The maritime tropical air mass and maritime equatorial. These air masses originate over warm oceans in the tropical and equatorial zones. They are quite similar in temperature and water vapor content. With their high values of specific humidity, both can produce heavy precipitation.
