Why can the typhoon make the highest temperature in Xiamen reach 39.6 degrees Celsius?

The rare high temperature weather in summer is closely related to the location of typhoon "Lichima" No.9 this year. Typhoons don't always bring clouds and rain, but they can also bring hot weather. This has a lot to do with the structure of the typhoon. There is a strong upward movement area of airflow near the typhoon eye, while the circulation around the typhoon is a downward movement area of airflow, and the upward airflow is easy to condense clouds and cause rainfall.

It will cause heavy rain in the affected areas, but when it flows downward, it will make the heat of the sun reach the ground unimpeded, leading to heat accumulation and high temperature weather. Therefore, when the periphery of the typhoon downstream dominates Xiamen, this typhoon has become a "fire typhoon" in Xiamen. Super typhoon "Lichima" is such a fire typhoon.

Since the day before yesterday, its peripheral downward airflow has affected Xiamen, causing the temperature to rise. Today, it continues to advance to the northwest, pointing directly to the coast of Zhejiang. Around noon, its center moved to the sea surface more than 500 kilometers northeast of Xiamen, and the downdraft reached its strongest stage in Xiamen, thus giving birth to a high temperature record.

The meteorological department predicts that Xiamen will still be affected by the downward airflow of "Lichima" in the next two days, and the weather will continue to be hot and summer, so citizens should pay attention to heatstroke prevention and cooling. Experts remind that outdoor activities at noon should be avoided in hot weather, and the sun is fierce during the day, so it is best to prepare for sun protection when going out; Pay attention to the safety of household electricity use and strengthen the prevention of accidents caused by overload of power equipment caused by high temperature weather; In summer, the weather is hot, the capillaries dilate, and it is easy to be attacked by pathogenic wind, cold and dampness. It is not advisable to use a fan to blow directly at the body when sleeping. In an air-conditioned room, the temperature difference between indoor and outdoor should not be too large. When sweating all over, it is not advisable to take a bath with cold water immediately to prevent the cold from invading the skin and getting sick.
