Cyclone Dolphin hits China at 150 km/h: Highest rainfall in 150 years, 1 million people evacuated

After causing havoc in Japan, Cyclone Dolphin has now reached China. It made landfall in the coastal areas of eastern China late on Sunday night. At that time, its speed was about 150 km per hour. After this, heavy rains started in many cities. The worst impact was seen in Shanghai, which recorded the highest rainfall in the last 150 years. According to Chinese officials, more than 10 lakh people have already been evacuated to safer places in view of the threat. According to Chinese media SCMP, the storm is now weakening. So China's Meteorological Agency has lowered the warning level. However, the threat of flooding due to incessant rains remains. There have also been incidents of landslides and landslides in some places. Here are 5 photos of the storm. As many as 943 flights were cancelled, local trains were also closed. As many as 943 flights were cancelled on Monday at the city's two major airports. A flight from Chengdu in southwest China to Shanghai failed to land in Shanghai on Sunday due to rain. The plane was diverted to Beijing after circling Shanghai for a while. After landing there, the plane returned to Chengdu at night. Apart from this, transport services for many general public, including local trains, were also closed. Flights resumed at Zhejiang's Ningbo International Airport on Monday afternoon. However, the airport said the impact of the storm was not yet completely over. In such a situation, some flights may be delayed or may have to be cancelled. Beijing, the capital of China, is also on alert. A red alert for heavy rains was issued in five districts of the city on Monday. The threat of landslides and floods was reported in some areas. The Beijing Meteorological Department has warned of rain continuing for the next three days. People have been advised not to venture out except for essential work and avoid outdoor activities. According to the China Meteorological Department, the storm is now moving in a northwesterly direction at a speed of 15 to 20 km per hour. According to the National Meteorological Centre, the dolphin's cloud system is spread over about 1,300 km. Why do cyclones occur frequently in China? 1. Located near and north of the equator, the western Pacific Ocean receives 25 to 30 hurricanes every year. This accounts for about 30% of the total hurricanes that hit the world. This is because the region is located near the equator (in the tropics). Due to the rotation of the earth, the force that rotates the winds (Coriolis effect) is very strong. After becoming a hurricane, it moves towards Japan, Taiwan, China, Korea and the Philippines with wind gusts. This is the reason why these countries have the highest number of hurricanes. 2. The warming of the ocean rapidly is the biggest reason for the formation and strengthening of cyclones. When the sea surface temperature rises, the water rises rapidly as evaporation. This steam acts as fuel for storms, making both winds and rain extremely intense. In 1901, the average temperature of the world's oceans was about 15.2°C to 15.3°C. In the last few years, the average global sea surface temperature has exceeded 21.1°C, the highest in history.
