Typhoon No. 19 expected course

Typhoon No. 20 expected course

Many of the typhoons that have occurred so far this month have headed west in the South China Sea, with No. 19 expected to take a similar course this time after Typhoons 15, 16, 17. and 18. .. In addition, another tropical low pressure that followed No. 16 took a similar course.

It appears that the bias of the high pressure of the Pacific has influenced the course of the typhoon. The high pressure from the Pacific that covers Japan in the summer is already far south of the main island, but this year the typhoon that occurred near the Philippines is difficult to move north because it protrudes further west than usual. And, thanks to the flow of the wind around this high pressure from the Pacific, it is often heading west in the near latitude of the Philippines.

This situation is expected to continue until November, and even if a typhoon occurs, it will be difficult to get close to Japan. On the other hand, Vietnam, which has been hit by heavy rains since early October, remains susceptible to typhoons and there are concerns that the damage will spread.

Typhoon No. 19 is expected to travel west across the South China Sea, passing through the Philippines and losing power.

Typhoon No. 20 moves slightly north of No. 19 and slow down over the sea east of the Philippines after Tuesday the 3rd. After that, as you can see from the large forecast circle, the course has yet to be decided at this stage. Check back frequently for the latest information and stay tuned for future changes to your course.

Typhoon number in normal years

Typhoon No. 20 is the seventh typhoon to occur in October this year. Since the average number of typhoons in October is 3.6, it is roughly double the average number and, along with 2013, 1992 and 1984, it is the highest number of typhoons in October.

Typhoon season in the South Sea is not over yet, as two or three typhoons occur each year in November.

Regarding the names of typhoons, 140 names proposed by the member countries of the international organization “Typhoon Committee” are prepared in advance and given in the order of appearance.

Typhoon No. 19’s name “Goni / 고니” was proposed by South Korea and is taken from the Korean word for swan (Kohakucho).
Typhoon No. 20’s name “Atsani” is a name proposed by Thailand and means thunder.
