Is there a pattern of Artest Pool on the meteorological cloud picture?

On June165438+1October 1 1 day, the cloud image of FY-4 high-definition visible satellite showed that the weather pattern in the western Pacific and the South China Sea changed again. Typhoon Ai Tao in the South China Sea and Typhoon Ai Tao east of the Philippines danced in circles before, but now Typhoon Ai Tao quickly weakened and dissipated after landing in Vietnam. 165434

However, the enhancement of typhoon ring height is not very smooth. From the infrared cloud picture, the convection in the core area is actually divided into two parts, twisted into a ball similar to the "Taiji Eight Diagrams" with a twisted "eye of the wind" structure in the middle. This form is still chaotic, indicating that although the typhoon ring height is increasing rapidly, the structure is still relatively poor, so the Central Meteorological Observatory thinks that it is only 13.

From the current point of view, the reason why the typhoon ring height has the shape of "Tai Chi Eight Diagrams" is because it is very close to the Philippines. The warm water area to the east of the Philippines and the terrain near the land make the convection in the core area of typhoon Aitao erupt violently, but the integration efficiency of typhoon ring height is limited, and the convection accumulates in the center in chaos, forming the present situation.

However, according to the forecast of the Central Meteorological Observatory, although the typhoon ring height is close to the Philippine Islands, it may actually continue to strengthen until landing, so there is still half a day to strengthen. According to the Central Meteorological Observatory, it may be strengthened to 15 typhoon level before landing, and it is likely to land in the Philippines at the most, which poses a great threat to the Philippines.

Another dangerous situation is that the rapidly increasing typhoon ring height may pass directly near Manila, the capital of the Philippines. As the capital of the Philippines, Manila is densely populated, with complex geological conditions, fragile ecology and insufficient disaster prevention capacity. The frontal attack of typhoon may cause great disaster. Therefore, China friends in Manila and surrounding areas must pay attention to safety, and coastal areas should pay special attention to destructive winds and storm surges.
