When did the convention of hurricane naming begin?
Tropical cyclone naming
Tropical cyclones that occur within the Northern Hemisphere between the anti-meridian and 100°E are officially named by the Japan Meteorological Agency when they become tropical storms.[2] However, PAGASA also names tropical cyclones that occur or develop into tropical depressions within their self-defined area of responsibility between 5°N–25°N and 115°E-135°E.[3] This often results in tropical cyclones in the region having two names.[3]
