Interest and activity in tropical meteorology have increased substantially within the past few years, in relation to other areas of the atmospheric sciences. Some af this growth has been stimulated by the Global atmospheric Research Program (Garp), which has placed strong emphasis on the need for understanding largescale motion systems in the tropics and their interaction with organized cumulus convection. This emphasis has keen reflected in plans for a vigorous tropical field program built on the experience of the Line Island Experiment (LIE) and the Barbados Oceanographic and Meteorological Experiment (Bomex). The first major Garp undertaking in this area will be an experiment in the tropical Atlantic during the summer of 1973 or 1974. A large portion of the tropical meteorology community has been involved in the implementation of the previous experiments and in the planning for the Garp tropical subprogram.
