8 Storms hit Philippines in just 33 days

[Shance]

Good day,

Alam ko hindi lang ako yung nagulat sa sunod sunod na bagyo na tumama sa Pilipinas. Nagresearch ako tungkol dito at ito ang resulta.

In context, in just 33 days 8 Storms/Typhoon ang tumama sa Pilipinas listed below;


Tropical Storm Nangka (Nika) - formed October 11, 2020
Tropical Depression Ofel - formed October 13, 2020
Typhoon Saudel (Pepito) - formed October 16, 2020
Typhoon Molave (Quinta) - formed October 23, 2020
Typhoon Goni (Rolly) - formed October 26, 2020
Severe Tropical Storm Atsani (Siony) - formed October 28, 2020
Tropical Storm Etau (Tonyo) - formed November 7, 2020
Typhoon Vamco (Ulysses) - formed November 8, 2020

As per PAGASA ang usual peak typhoon season natin is July - August and slowly decreased activity in month of September to October. But in this October six Storm formed and entered in PAR which is unusual.

Even I compare the most active season in West Pacific in year 1993 only 3 storms entered in PAR in month of October.

Now let's move to the reason kung bakit sunod sunod yung Bagyo in past few months. (Discretion: Hindi ako Meteorologist ang mga opinyon sa baba ay base lang sa research at pwede rin mali ang mga ito)

1. La Nina - Pag may La Nina mas madaming bagyo ang nafoform sa West Pacific due to low wind sheer and high sea temperature. In La Nina, ang cold waters ay nag eextend hanggang sa Central Pacific Ocean at tinutulak nito yung warm ocean papuntang West Pacific. Take note once na may La Nina mas wetter sa West Pacific including Philippines and drier naman sa eastern Pacific Ocean like Chile.

2. Madden-Julian Oscillation (MJO) - isa sa mga complex na weather season, ito ay mga eastward moving disturbance of clouds, rainfall and pressure and precipitation na umiikot sa mundo simula sa Indian Ocean at magtatapos din sa Indian Ocean in 30 to 60 days in average. May mga phases ito from Phases 2 to 8 and it will end to Phase 1. Notable dito yung Phase 5 to Phase 6 which is yung phase na mataas na precipitation sa West and Central Pacific Ocean. Have to types Convection type (Wetter) and Suppressive type (Drier)

3. Above Sea Surface Temperature - ang Philippine sea temperature ay above average ranging 31 to 32 degrees celcius. Ang normal SST is 30 degree.

4. High Pressure Area - Also known as typhoon killer. Ang HPA ay kadalasan nasa northern and southern hemisphere. Also isa mga driving force ng mga bagyo.


Because of La Nina the sea temperature in Philippine sea raised above average and more precipitation and low wind sheer + MJO is in Phase 5 Starting October 3, 2020 providing pressure, percipitation and cloud disturbances + Above Average Sea Surface Temperature and HPA in above Philippines driving the typhoon to Philippine instead of moving to north north east. It all happen in October 2020.

Still may La Nina pa i hope na wala nang maform na bagyo this remaining months.

Quite long sorry.

last few years iba yung angle trajectory - track path nang mga bagyo, dadaan muna sila sa south pacific ocean papuntang east of mindanao tapos biglang tataas 45-90 degress papuntang Luzon.

late 90s early 2000s iba rin yung route nang bagyo between October to early January, dumadaan sa Visayas mga 1-3 na bagyo. Yan yung naalala ko.

Also I remember bagyong Roping 1994 ata yun di ko na matandaan, pero category 4 or 5 ata yun, dumaan dito sa Visayas.
