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.
Air masses build over source regions that have relatively similar ground surface characteristics. Air masses that build over the land are called continental air masses while air masses that build over the open ocean are called maritime air masses. Air masses cover 100 s to 1000 s of kilometers of distance. What causes these huge regions of air to move? Air masses build when the air stagnates over a region for several days/weeks. To move these huge regions of air, the weather pattern needs to change to allow the air mass to move. One major influence of air mass movement is the upper level winds such as the upper level winds associated with the jet stream.
