tái fēng台风bī jìn逼近：wèi shén me为什么qiū tiān秋天de的tái fēng台风zhè me这么qiáng强？
Recently, this year's 30th typhoon, “Kammuri,” has been approaching the waters off southeastern China.
Many people think that typhoons occur only in summer.
In fact, typhoons that occur from September to November are called “autumn typhoons.”
There is also a saying among Chinese people: “Autumn typhoons are fiercer than tigers,” meaning that typhoons in autumn are often more severe than those in summer.
Meteorological experts explain that autumn typhoons are so strong mainly for several reasons.
First, after receiving sunlight throughout the summer, ocean water temperatures remain high, providing typhoons with plenty of energy.
Second, most autumn typhoons form far out at sea and have more time to develop over the ocean, so they can easily become strong typhoons.
More importantly, cold air from the north begins moving south in autumn.
When cold air meets a warm, moist typhoon, the two collide. This not only brings heavier rainstorms but also expands the area affected by strong winds.
Under the influence of Typhoon Kammuri, some areas of Taiwan, Fujian, Zhejiang, and Shanghai will experience strong winds and heavy rain.
To reduce the danger brought by the typhoon, Fujian, Zhejiang, and other places have already made preparations. Many fishing boats have also returned to port early to shelter from the wind.
Meteorological experts remind everyone not to underestimate the power of autumn typhoons.
Residents in affected areas should pay close attention to the latest weather forecasts, avoid dangerous places, and stay safe.
