TEXAS-WEST GULF CYCLONES*

Abstract From a study of 388 extratropical cyclones originating in the Texas-West Gulf region during a 40-year period various characteristics of their formation and early life history are determined. Some of the common synoptic sequences leading to the formation of these cyclones are derived from a more thorough study of recent synoptic charts and are described from the standpoint of the upper-air circulation. The 388 selected cyclones are summarized in terms of variations in frequency, favored regions of origin, motion, deepening, and relation to the rainfall of the central Gulf coast. The relatively great frequency of cyclone formation near the Texas coast is considered to result from the interaction of the general circulation on the unique physiographic environment of the region.
