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.
The same reaction happens here, except the two forces slam into each other. The cold air forms a wedge underneath the warm air, allowing it to basically ride up into the troposphere on its back and generate rain clouds. There are four main kinds of fronts, classified by airflow momentum. In a warm front, a warm air mass moves into a cold air mass. In a cold front, the opposite occurs. In a stationary front, neither air mass advances. Think of it as two fronts bumping into each other by accident. In an occluded front, a cold front overtakes a moving warm front, like an army swarming over a fleeing enemy. Convergence: When two air masses of the same temperature collide and neither is willing to go back down, the only way to go is up.
