Through El Niño–Southern Oscillation

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) named tropical cyclones that were judged to have 10-minute sustained wind speeds of at least 65 km/h (40 mph) anywhere in the basin, whilst the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigned names to tropical cyclones which moved into or formed as a tropical depression in the Philippine Area of Responsibility (PAR) located between 135°E and 115°E and between 5°N and 25°N regardless of whether or not a tropical cyclone has already been given a name by the JMA. Tropical depressions that were monitored by the United States' Joint Typhoon Warning Center (JTWC) were given a number with a "W" suffix.

Seasonal forecasts

During the year, several national meteorological services and scientific agencies forecast how many tropical cyclones, tropical storms, and typhoons will form during a season and/or how many tropical cyclones will affect a particular country. These agencies included the Tropical Storm Risk (TSR) Consortium of University College London, PAGASA and Taiwan's Central Weather Bureau. The first forecast was released by PAGASA on December 22, 2021, in their monthly seasonal climate outlook predicting the first half of 2022. They predicted that only 0–3 tropical cyclones were expected to form or enter the Philippine Area of Responsibility between January and March, while 1–4 tropical cyclones are expected to form between April and June. PAGASA also stated that ongoing La Niña conditions could last until it transitions back into ENSO-neutral conditions by the second quarter of 2022.

On May 5, Tropical Storm Risk (TSR) issued its first forecast for the 2022 season with ongoing La Niña still anticipated until roughly the third quarter of the year, TSR predicted that tropical activity for 2022 will be slightly below average predicting 23 named storms, 13 typhoons and 7 intense typhoons. TSR remained constant with their prediction in their second forecast in July. On August 9, TSR released their third and final forecast for the season, with the only changes is increasing their typhoon numbers by 14, and decreasing the intense typhoon numbers down to 6. The ACE Index forecast was significantly lowered to 166, and was based on the then-current index as of early August and the reduction of cyclonic activity in the month of June.
