About 70% of WNP tropical cyclones (TCs) formed in or 39 entered the Philippine region during 1945-2011. Here, a climatology of Philippine TC metrics is 40 developed, including mean annual frequencies, landfalls, TC days, season lengths, season earliest 41 and latest start/end dates, genesis locations, and tracks. Two distinct TC seasons, the less active 42 (LAS; January 1-May 31) and more active (MAS; June 1-December 31) seasons, are evident.
