The sketch diagram of cloud/precipitation features for Tropical Depression (Left panel) and Tropical Cyclone (right panel) under the intensification stages.
We want to know if there are unique features of deep convective cloud (DCC), rain, and cloud properties that can be used to predict the rapid intensification (RI) of a tropical cyclone. RI can be predicted using DCC in all storm categories. Precipitation is also useful in anticipating RI but for weaker storms only. The deep convection, rain, and cloud properties near the center of rapidly intensifying storms suggests that clouds within that region has deepened already as compared to the clouds that far away from the center. All storms that are rapidly intensifying share the same DCC, rain, and cloud properties characteristics near the center. The different characteristics observed at the beginning and at 24 hr of RI are more related to their intensities and intensification rates (or the size of their radii of maximum wind).
