Why are typhoons frequent this year?

Under the global background, the annual frequency of typhoon weather is still high, but according to the report of the meteorological department, the frequency of typhoon this year is higher than usual, the main reasons are as follows:

First, the global temperature is rising year by year, and even the temperature can reach 27 or 28 degrees, which leads to the typhoon meeting the basic requirements of the sea surface. The vast sea level, driven by heat, provides basic kinetic energy for the occurrence of typhoons, making the sea water churn gradually. Second, the formation of tropical vortex leads to the decrease of central air pressure and the formation of typhoon eye, and the airflow moves up one by one, bringing strong convective weather. Third, at the beginning of the typhoon, the wind speed difference directly above the weak pressure is small, which will drive the heat in the air to condense.

This year's higher temperature than normal is an important factor of frequent typhoons, which provides thermal kinetic energy for the development of strong typhoons. Some experts have shown that every degree of sea level temperature rise will bring about an increase in typhoon wind speed.

Although typhoon is one of the common atmospheric phenomena, it can gather the heat in the air and release it to all parts of the world. It is an important way of water circulation and atmospheric circulation, which can ensure the heat transfer between land and ocean. However, according to the meteorological monitoring results, this year's typhoon is very destructive, and its speed is reduced under the condition of constant intensity, and it also brings super rainfall, which is also the root cause of recent floods in many provinces and cities in the south. Frequent typhoon weather seriously affects everyone's daily life, so the meteorological department needs to be vigilant, predict in advance, and inform residents of the basic hedging methods.

In a word, typhoon is one of the important weather that affects the production and life of Chinese residents. Under the influence of the warming weather, the frequency of its occurrence gradually increases, becoming a bad way of high temperature release. In order to prevent unnecessary damage to people and property, everyone should pay attention to protecting the environment, reducing greenhouse gas emissions, adopting green travel mode and avoiding the warming of the weather.
