The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line. Storms that form east of the date line and north of the equator are called hurricanes; see 2004 Pacific hurricane season. All tropical storms that develop in the western Pacific Ocean are assigned a name by the Japan Meteorological Agency (JMA). Tropical depressions in this basin have a "W" suffix added to their number by the Joint Typhoon Warning Center (JTWC). This can often result in the same storm having two names.
The 2004 season was a very active season. 29 storms were named in this year and 19 of them reached typhoon intensity. The accumulated cyclone energy (ACE) index of this season amounted to 60% above the normal level for Pacific typhoon seasons, at 464. This makes 2004 season the third most active season in recorded history, only after 2015 and 1997.[3]
