Continental Tropical : These are the hot, dry air masses which originate over northern Mexico and the southwestern United States. This air mass enters the United States through New Mexico, Arizona and western Texas and frequently moves eastward to northeastward bringing hot, dry air to Texas.
A tropical maritime airmass will be very warm and humid. A tropical continental airmass usually covers much of the United States in the summertime. Other airmass types include arctic, equatorial, and monsoon. Fronts are the boundaries between air masses of different temperature. Extratropical cyclones (low pressure areas) also form along these fronts and draw their energy from the temperature difference between air masses. On average, warm air masses tend to flow poleward, and cold air masses tend to flow equatorward, helping to cool the tropics and warm the polar regions. (page last updated 11/27/2010)
