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.
Because of a warm air massâs higher temperature and thus lesser density, mixing between the two air masses is unlikely. Being light, the warm air mass is unable to displace the cooler air mass and instead is forced upward along the upper boundary of the colder air in a process known as overrunning.arm fronts lie within broader troughs of low pressure than cold fronts, and move more slowly than the cold fronts which usually follow because cold air is denser and less easy to remove from the Earth's surface.
