2020 Pacific typhoon season
The 2020 Pacific typhoon season is a slightly below-average event in the annual cycle of tropical cyclone formation. The season runs throughout the year, though most tropical cyclones typically develop between May and October. The first half of the season was unusually inactive, with only four systems, two named storms and one typhoon at the end of July. It is the fifth-latest start in the basin on record, slightly behind 1973.
About 2020 Pacific typhoon season in brief
The 2020 Pacific typhoon season is a slightly below-average event in the annual cycle of tropical cyclone formation. The season runs throughout the year, though most tropical cyclones typically develop between May and October. The first half of the season was unusually inactive, with only four systems, two named storms and one typhoon at the end of July. It is the fifth-latest start in the basin on record, slightly behind 1973, and the first to start this late since 2016. This was due to the fact that the El Niño–Southern Oscillation was seeing neutral conditions across the Pacific, and could persist until midyear. 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 tropicalcyclones which can often result in a cyclone having two names. The Japan Meteorological Agency will name a tropical. cyclone should it be judged to have 10-minute sustained wind speeds of at least 65 kmh anywhere in the. basin, whilst the Philippine Atmospheric, Geophysical and Astronomical Services Administration assigns names to. tropical cyclONES which move into or form as a tropical depression in their area of responsibility. The PAGASA predicts that only 0–4 tropical. Cyclones are expected to form or enter the Philippine Area of Responsibility between January and March, while 5–8 tropical cyclONE are expected. to form between April and June. On July 9, the TSR issued their forecast for the season, predicting a well-below average season with 26 tropical storms, 15 typhoons and 8 intense typhoons.
On August 6, TSR lowered their numbers to 21, lowering their numbers for the third and final months of the year. They predicted that 6–10 tropical cycloned are expected between the months of July and September, while 4–7 tropical cycloning are expected in December. In October and November, a slew of tropical disturbances and cyclones hit Central Vietnam triggering severe flooding and killing more than 270 people. In August, Typhoon Hagupit and Severe Tropical Storm Mekkhala struck Eastern China while Typhoons Bavi, Maysak, and Haishen struck the Korean Peninsula in a span of only two weeks. In November, Typhoon Goni became the strongest typhoon in the season surpassingHaishen, and the world’s strongest tropicalcyclone on record in 2020. It then hit Cambodia causing more severe flooding, affecting tens of thousands of homes and over 180,000 hectares of farms. Later that month, Typhoon Saudel formed, hitting the Philippines. It then caused more severe. flooding and affecting tens- thousands of houses and farms, with 44 deaths were confirmed in that nation. In December, Typhoon. Goni hit Cambodia and killed more than270 people, with more than 300,000 people affected by the flooding in Central Vietnam and Cambodia. In January 2020, the Tropical Storm Risk Risk Consortium of University College London, PAGasA and Taiwan’s Central Weather Bureau released their monthly seasonal climate outlook.
