The 2020 Pacific typhoon season is a late-starting event in the annual cycle of tropical cyclones in the western Pacific Ocean . The season runs all year round, but most tropical cyclones develop in this basin between May and October. The first named storm of the season, Vongfong, formed on May 10th.
In the northwestern Pacific - the area north of the equator between 100 ° east longitude and 180 ° east longitude - there are two meteorological institutions that give names to tropical storms, which means that some storms have two names. The Japan Meteorological Agency (JMA) gives a name when a storm somewhere in the western North Pacific reaches wind speeds of at least 65 km / h for ten minutes. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical depressions or storms that arise or migrate between 135 ° and 115 ° east longitude and between 5 ° and 25 ° north latitude, even if the JMA has already given a name. Tropical weather is also monitored by the United States' Joint Typhoon Warning Center (JTWC) . Their warnings are aimed primarily at US military facilities.

During the year, several meteorological services and institutes predict how many tropical storms and typhoons will form during a season and / or how many will hit a particular country. Among them are the Tropical Storm Risk Consortium (TSR) of University College London , PAGASA and Taiwan's Central Weather Bureau . The first forecast of the year was published by PAGASA on January 22nd for the first half of the year. PAGASA predicted that between January and March 0 to a maximum of four tropical depressions or storms will form in their area of responsibility, PAGASA expected five to eight systems between April and July. PAGASA justified this with neutral terms of the El Niño-Southern Oscillation , which lasted until mid-year.

On May 9th, the JTWC first reported the formation of a low pressure area in Micronesia , and the next day the JMA found that it had developed into a tropical depression east of Mindanao . Convection gradually began to obscure the center. PAGASA gave the system the local name Ambo , as it was the first system of the year to reach their area of responsibility. The system slowly began to drift westward and did so for the next few days, steadily intensifying, with occasional convective bursts on the edge of the slightly rolled-out circulation. On May 12, the JTWC also classified Ambo as a tropical depression and assigned the designation 01W . Over the course of the day the system intensified further and took a more northerly direction. A well-defined rain band formed on its northwest side. At this point, the JMA upgraded the depression to a tropical storm and gave the first name on the list of names, Vongfong. A little later, the JTWC also upgraded the system to a tropical storm.
Due to favorable conditions with low wind shear , sea surface temperatures of 29 to 30 ° C and an excellent discharge, Vongfong began a rapid intensification early on May 13th . Shortly thereafter, the JMA upgraded the system to a severe tropical storm and the JTWC upgraded it to a typhoon equivalent to Category 1 on the Saffir-Simpson wind scale, with sustained one-minute winds of 130 km / h. PAGASA and JMA upgraded the system to a typhoon later in the day, while the JTWC upgraded the system to a Category 2 typhoon as the eye would be more noticeable. A few hours later, Vongfong intensified equivalent to Category 3. At 12:15 p.m. PST (04:15 UTC ) on May 14, Vongfong landed in San Policarpo , Eastern Samar . After landfall on Samar , Vongfong weakened, passed through the Ticao Pass and approached Sorsogon .
Storm signal number 3 was given for the whole of Eastern Samar and parts of Northern Samar in preparation for the typhoon . Tens of thousands of residents of the island were forced to seek shelter, which because of the COVID-19 pandemic in the Philippines only accepted half of the otherwise permitted number of people seeking protection, who also had to wear face masks.

Storm names
In the northwestern Pacific Ocean, both the Japan Meteorological Agency (JMA) and the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assign names to tropical cyclones in their area of responsibility, so that individual storms are given two different names. The RSMC Tokyo - Typhoon Center he JMA assigns the international names on behalf of the Typhoon Committee of the World Meteorological Organization , provided it comes to the conclusion that the continuous ten-minute wind speeds have reached 65 km / h. PAGASA assigns names to all tropical low pressure areas or tropical storms that form or migrate into their area of responsibility between 135 ° and 115 ° east longitude and 5 ° and 25 ° north latitude, even if the system already has an international name. Both WMO and PAGASA delete the names of particularly momentous tropical cyclones. Names that have not yet been used are marked in gray (unused) .
International names
The JMA chooses the name of a storm from a list of 140 names, ten of which have been proposed by the states and territories that make up the ECAP / WMO Typhoon Committee. Any deletions of names of particularly serious cyclones will be announced by the WMO in 2021; their replacement names will be published in 2022. The next 28 names on the list before the season are below; they are supplemented in brackets by the respective four-digit numerical designation as soon as a name is used. The numerical designation 2001 consists of two digits for the year (2020 → 20 ) and two digits for the consecutive numbering.

The names used in 2020 are from the same list of names that was last used in 2016 and that will be reused in 2024 . These names are unchanged, with the exception of Kristine, Leon and Nika, who have replaced the deleted names Karen , Lawin and Nina . The names from the replacement list are used when all the names on the list scheduled for 2020 have been used up. The storms, which are also named by the RSMC, are given the international numbering in brackets.
