The 1983 Pacific typhoon season was the latest start for a Pacific typhoon season on record, and also slightly below-average in terms of named storms. It ran year-round in 1983, but all tropical cyclones formed between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. A total of 32 tropical depressions formed this year, of which only 23 became tropical storms and were assigned a name by the Joint Typhoon Warning Center. Additionally, tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names. This year, a total of 23 storms were named this way.
The season had a late start, as the first system did not form until early June for the first time since 1973.[1] The last tropical cyclone dissipated in mid-December. Of the 23 tropical storms, one formed in June, three formed in July, five formed in August, two formed in September, six formed in October, five formed in November, and one formed in December. Ten storms reached typhoon intensity according to the Japan Meteorological Agency, of which four reached super typhoon strength. Fifteen of the tropical cyclones made landfall, with six moving through the Philippines, six striking China, six moving into Vietnam, and three moving in Japan. Vera, Wayne, Kim, and Lex led to over half of the fatalities from tropical cyclones this season. Forrest became the fastest-developing tropical cyclone on record for the western Pacific Ocean, with a pressure drop of 92 hectopascals (2.7 inHg) in a 24‑hour period.[1]
The scope of this article is limited to the Pacific Ocean to the north of the equator between 100°E and 180th meridian. Within the northwestern Pacific Ocean, there are two separate agencies that assign names to tropical cyclones which can often result in a cyclone having two names. The Japan Meteorological Agency (JMA)[nb 1] will name a tropical cyclone if it has 10-minute sustained wind speeds of at least 65 km/h (40 mph) anywhere in the basin. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones which move into or form as a tropical depression in the Philippine Area of Responsibility (PAR), located between 135°E and 115°E and between 5°N–25°N, regardless of whether or not a tropical cyclone has already been given a name by the JMA. Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center (JTWC)[nb 2][nb 3] are given a number with a "W" suffix.
