What is the cause of Weiterson?

(English: severe tropical storm Vicente, international code: 1208, joint typhoon warning center: 09W, Philippine Atmospheric Geophysics and Astronomy Administration: Ferdie) is the eighth named storm in the 20 12 Pacific typhoon season. "Vicente" is a Chamorro name provided by the United States.

The reason why Wittson appeared

On July 22, 2002, at 0/.2010, the center of Tropical Storm No.8 "Vicente" was located in the northern part of the South China Sea, about 530 kilometers southeast of Zhanjiang City, Guangdong Province, that is, north latitude 19.3 degrees and east longitude 1 15.0 degrees. It is estimated that "Vicente" will move to the west-northwest direction at a speed of about 10 km per hour, and gradually approach the western part of Guangdong to the eastern coast of Hainan, and its intensity will gradually increase. It will land in the coastal area from Yangjiang, Guangdong to Lingshui, Hainan from the evening of 23rd to the morning of 24th. At 8: 00 on the 23rd, the South China Sea Forecasting Center of the State Oceanic Administration issued an orange warning of waves and a yellow warning of storm surge, and there will be 8 meters of wild waves in the northern part of the South China Sea.

2. With the strengthening of solar radiation, the weather is getting warmer and warmer, and the warm and humid airflow from the south carries a lot of water vapor and heat, so it is easy to accumulate energy in the atmosphere. When the cold air in the north invades the warm and humid air mass in a proper way, various strong convective weather systems will be formed in some areas, which will release the accumulated water vapor and energy in the air in a short time, thus forming strong lightning, short-term rainstorm, strong wind and even hail, tornado and other strong convective weather. In addition, due to the relatively active and strong warm and humid air flow this year compared with the same period in recent years, severe convective weather in the south appeared many times during this period, and caused some secondary disasters. Many natural disasters, especially high-grade and high-intensity natural disasters, often induce a series of other disasters, which is the disaster chain. The earliest disaster in the disaster chain is called primary disaster; Disasters induced by primary disasters are called secondary disasters. Sometimes, the casualties and losses caused by secondary disasters are even greater than those caused by primary disasters.
