Abstract: Tropical cyclones (TCs) show diverse spatial patterns of rainfall, which is an important factor in damage caused by TCs. This study classifies rain patterns of TCs over the North Atlantic using a Convolutional AutoEncoder (CAE) trained with precipitation estimates from satellite observations. We found six clusters of TC rain patterns and confirmed that they showed distinct characteristics in their spatial patterns and geographical locations of occurrences. The characteristics of each cluster are closely related to storm intensity and their surrounding environmental conditions such as moisture supply and vertical wind shear. In addition, we found four types of intense TCs (maximum wind speed > 64 knots) according to the spatial patterns of moisture around TCs using the CAE. The four clusters of intense TCs present significant differences in time evolution of TC intensity, landfall region and frequency between them.
