Louie Jane Eleccion, LPT

This document defines typhoons and their development. It explains that typhoons form over warm ocean waters through the process of cyclogenesis, where converging winds and rising humid air lead to the formation of clouds and rotating storm systems. The Philippines is prone to typhoons because it is located in the western Pacific Ocean, an area where typhoons frequently develop and make landfall due to its warm waters and location within the typhoon belt.
