[Proof of a cold wave] A vortex cloud called "Kalman Whirlpool" appears in the East China Sea!


2025/02/18 15:57

TOPICS IMG

Starting today, the 18th (Tuesday), the second "strong cold wave" of this month has been hit.


Today, the first day of the cold wave, a "Kalman Whirlpool" appeared in the East China Sea.

If you look at the image of the weather satellite Sunflower True Color reproduction at 10am today, Tuesday the 18th, you can see swirl-shaped clouds lined up regularly in the East China Sea.

This is the "Kalman Whirl."

A Kalman vortex is a sequence of vortices formed behind an obstacle located perpendicular to an object in the flow.

This vortex row can also be seen in clouds, and when topography and weather factors overlap, two rows of vortex clouds line up in a regular manner.

The length of the cloud vortex is approximately 500-1000km, and can be seen from the
weather satellite.

Kalman vortices often occur in
+When northwest winds are strong in
+When there is a strong northwest wind,
+Downwinter mountains (over 1000m above).



It is often seen in downwinds such as Jeju Island in Korea, and
/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/B/



/Basically, the cold air will be inhabited over the next three-day holiday, and this time it will be a "long-term stay cold wave."

There will be many times when the cold waves will peak over next week, so you may be able to see the "Kalman Whirlpool" again when the cold air is getting stronger.








Even after the cold wave hit, the sea surface temperature was "very high" and the "first day of drift ice" was the slowest recorded history in Abashiri [Marine Summary February 9th - 15th, 2025]

#Air pressure arrangement And Wave
On the 9th, there was a strong winter pressure system around Japan.
The waters near the Ogasawara Islands and off the coast of the southeastern Hokkaido were wide, and the Sea of Okhotsk was large, with a wave height of over 6m.

From the 10th to 11th, high pressure systems began to rise from the continent, but
Isbar lined in northern Japan continued to be crowded, and
Steaks continued to occur in the Sea of Okhotsk and off the coast of Sanriku.

On the 12th, the center of high pressure systems moved south to Japan, and the front reached the East China Sea.
At night, the waves rose to 3m in the East China Sea.

On the 13th, a low pressure system accompanied by a front rapidly developed in the waters near the Kuril Islands, and the winter pressure system arrangement increased along the 14th.
The waves were still high off Sanriku, and rockets were over 4m high.

On the 15th, the waves were covered in mobile high pressure, and the high waves from the west subsided.

# Sea surface temperature
Sea surface temperature in the Sea of Japan continued to be higher in the central and western continental areas, with a maximum of 3 C higher than normal.


The waters near the East China Sea and the Southwestern Islands continue to be slightly lower than normal.
On the Pacific side, it was offshore Ashizuri Cape to Shio Cape, where the Kuroshio Current is ripped, and
The situation continued to be slightly lower than normal.

The Kuroshio Current continues to travel north as far as Sanriku off the coast of Sanriku.
It was quite high off Sanriku, with a maximum temperature of 6 C.


The offshore off the coast of Hokkaido was also significantly higher than normal, with the maximum temperature being 5 C higher.

Sea ice is moving south in the Sea of Okhotsk.

There is a risk of heavy snowfall at the warning level on the Sanin, Tokai, northern Kanto, Hokuriku, and the Sea of Japan side of Northern Japan.
Please be careful of traffic disruptions caused by heavy snowfalls and blizzards.
It is also likely to cause heavy snow on flat lands on the Pacific Ocean, where there is usually little snow. There are some areas where snow is piled up even in flatlands in Osaka Prefecture, causing heavy snow to occur in northern Mie Prefecture, and snow clouds will flow into southern Mie Prefecture.
Please be careful of the latest weather and traffic information as it may affect transportation.

#Sanin~ Hokuriku: Even after the first wave, the enemy is left unguarded due to the influence of JPCZ
Although the first wave passes on the 20th (Thursday), the next day, the mountain passes over the first wave, but due to the influence of JPCZ formed in the Sea of Japan, it will be on the Sanin-Hokuriku Sea of Japan side. The developed snow clouds will flow into the air.
JPCZ is expected to be heading towards Sanin in the morning on the 20th (Thursday) and towards Wakasa Bay through the evening.
If snow clouds flow into the same location, there is a risk of heavy snowfall of the warning level, so even if the first wave passes, it seems that you cannot let your guard down.

#The second wave hits the ground during the three-day holiday
Super strong cold air has continued to flow over Japan, and the winter pressure arrangement is expected to last for several days.

Snow is especially noticeable along the mountains in the Tohoku and Hokuriku regions. It is likely to intensify, and snow may continue to fall in the same place and cause a sudden increase in snow. In the Kanto, Koshin, Tokai and Kinki regions, there are many areas around the mountains, with 50cm of snowfall 24 hours a day, until 6am tomorrow.
In Tokai, some of the snow clouds will pass from Wakasa Bay to Ise Bay, and there will be some areas where snow will accumulate on flatlands in Mie and Aichi Prefectures. There is a risk that snow will suddenly increase in places where there is usually not much snow, which could affect transportation. Please check the latest traffic information frequently.
