The horse latitudes, or torrid zone, [20] is roughly at the 30th parallel and is the source of warm high pressure systems. As the hot air closer to the equator rises, it cools, losing moisture; it is then transported poleward where it descends, creating the high-pressure area. [ 21 ]
[9] The Köppen climate classification system was modified further within the Trewartha climate classification system in 1966 (revised in 1980).

A common track of a Panhandle Hook winter storm as it curves from Texas, northeastward towards the Great Lakes region. A panhandle hook (also called a pan handle hook [1] or Texas hooker [2]) is a relatively infrequent winter storm system whose cyclogenesis occurs in the South to southwestern United States from the late fall through winter and into the early spring months.
