MANILA, Philippines – The country had its first tropical cyclone of 2020 in May, when the Ambo tropical depression formed in Mindanao.
The Philippines receives an average of 20 tropical cyclones per year.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) gives local names to tropical cyclones when they enter or form within the Philippine Area of Responsibility.
These are different from the international names assigned by the Tokyo-Typhoon Center Specialized Regional Meteorological Center. (READ: QUICK FACTS: tropical cyclones, rain warnings)
In the case of PAGASA, it has 4 sets of tropical cyclone names that are used every 4 years. These names were previously listed, but the list is updated when certain names are removed or no longer used.
Below are the names for 2020, which will also be used in 2024, 2028 and 2032.
If the 25 names on the original PAGASA list for the year are exhausted, the names of the next tropical cyclones will be taken from an auxiliary list, which is also already prepared.
Why are certain names removed? PAGASA removes a tropical cyclone name from the list when it is particularly deadly or destructive.
If a tropical cyclone causes at least 300 deaths and / or P1 billion in damage to agriculture and infrastructure, it is replaced by another name that begins with the same letter.
For example, two names from 2019 are the last to be dismantled: Tisoy and Ursula. The new name for T under that set is Tamaraw, and for U, Ugong.
Typhoon Tisoy (Kammuri) hit parts of Luzon in early December 2019, causing 4 deaths and P6.6 billion worth of damage to agriculture and infrastructure.
Typhoon Ursula (Phanfone), which crossed the Visayas and parts of Luzon during the Christmas season, left 57 dead and P4.3 billion worth of damage to agriculture and infrastructure. – Rappler.com
