The synoptic situations which bring serious freezing weather to the Florida Peninsula are discussed generally by presenting various weather charts for an average of 41 freezing days which occurred during four winters. More specifically and individual freezing situation is compared with the four-year average and the three-dimen sional motion, temperature distribution and time changes of temperature are dealt with in some detail. A speculative scheme is presented which might permanently eliminate serious freezing in the Florida Peninsula. Before any solution can be reached, it t necessary to be able to define the problem with more accuracy. An observational program is proposed as a first steetin this direction. (Author).
