Abstract : During the past few years the existence of tropical cyclones of typhoon intensity, but lacking the vertical extent of the classical model, have been reported. Five such shallow systems were investigated by compositing reconnaissance and rawinsonde data with respect to the center. Although emphasis was placed on POLLY (1968), a composite model was derived from the five storms. Some of the characteristics found in the model were the lack of convective activity, the existence of a warm core in the lower levels but very little warming aloft, and an open eyewall rather than the closed eye found in classical typhoons. Some comparisons with the classical model are made but detailed reconnaissance data are needed to explain the differences between shallow and normal typhoons. (Author)
