Will Kanu go to Fujian?
On August 8, 2023 10, the Central Meteorological Observatory continued to issue a typhoon blue warning. The center of the No.6 typhoon "Kanon" (a severe tropical storm) this year is located at 8 o'clock today (8th) in the northwest Pacific Ocean about 285 kilometers south of Kagoshima, Kyushu, Japan, which is 29.0 degrees north latitude and 0/30.9 degrees east longitude. The maximum wind force near the center is 1 1 (30m/s), the lowest air pressure in the center is 975 hectopascals, the radius of the seventh-level wind ring is 320km, and the radius of the tenth-level wind ring is 120- 160km.
"Kanu" will move to the northwest at a speed of about 10 km per hour, and its intensity will be enhanced, and it will gradually approach the southern coast of the Korean Peninsula. On August 8, 2023 18, the Central Meteorological Observatory continued to issue a typhoon blue warning. The center of this year's No.6 typhoon "Kanon" (a strong tropical storm) is located on the northwest Pacific Ocean about 225 kilometers south of Kagoshima, Kyushu, Japan at 5 pm today (August 8).
That is, 29.5 degrees north latitude and 0/30.7 degrees east longitude. The maximum wind force near the center is 1 1 (30m/s), the lowest air pressure in the center is 970 hectopascals, the radius of the seventh-level wind ring is 320km, and the radius of the tenth-level wind ring is 120- 160km. "Kanu" will move to the north-north direction at a speed of about 15 km per hour, and its intensity will be enhanced, and it will gradually approach the southern coast of the Korean Peninsula.
Life cycle of typhoon development:
After a day of sun exposure, strong cumulonimbus clouds will form on the sea surface. The hot air in these cumulonimbus clouds rises, and the surrounding cold air is constantly replenished, and it rises again when it meets heat. This cycle makes the air above warm and the air below cool. The evaporation of water vapor in the hot air above expands the range of cloud belt, and the expansion of cloud belt makes this movement more intense. Affected by the geostrophic bias, the expanding cloud cluster rotates counterclockwise (clockwise in the southern hemisphere), forming a tropical cyclone.
The centrifugal force generated by the rotating air in the tropical cyclone throws the air outward, and the air in the center becomes thinner and thinner, and the pressure becomes smaller and smaller, forming the initial stage of tropical depression-typhoon. Because the air pressure in the tropical depression center is lower than that outside, the surrounding air rushes into the tropical depression and rises when it encounters heat, which provides more energy to the tropical depression, exceeding the output energy. At this time, the air in the tropical depression rotates more violently, the maximum wind force in the center increases, and the central air pressure further decreases.
When the maximum wind force near the center reaches a certain standard, it will be upgraded by one level. Tropical depression rises to tropical storm, then to strong tropical storm, typhoon, and sometimes to strong typhoon or even super typhoon, depending on the ratio of energy input and output. If the input energy is greater than the output energy, the typhoon will strengthen, otherwise it will weaken. After a long road of development, typhoons have become powerful and capable of causing disasters. If you land at this time, it may cause great losses.
A typhoon has two dead ends. The first one is that after the typhoon lands on land, it will weaken and die quickly due to the joint influence of ground friction and insufficient energy supply, and the residual cloud system after its death can bring heavy rainfall to a certain place for a long time. The second is that after a typhoon lands, it is easy to degenerate into an extratropical cyclone to the north, and after it degenerates into an extratropical cyclone, it will generally die out.
