In response to Xuan Lannuo, China Eastern Airlines tied up its aircraft at Hongqiao Airport. How powerful will this typhoon be?

This year’s Typhoon No. 11, Xuanlannuo, is the first typhoon with super strong winds in 2022. The formation of such a powerful typhoon is inseparable from the extreme high temperatures we have experienced around the world this year. This year's extreme high temperatures are spreading across the world. Not only our country, but also many Western countries are also deeply affected by extreme high temperature weather.

This year’s high temperature weather is particularly prominent in places such as Sichuan and Chongqing in my country. High-temperature weather. Under the atmospheric circulation situation, the negative high-pressure anomaly in the northwest Pacific is the main cause of persistent high-temperature weather. The influence of this extreme high temperature weather can also easily lead to cautious downdrafts, causing the sea surface temperature to rise to a certain level. At this time, a large amount of heat will accumulate in the sea, and this heat will form the basis for this year's typhoon. Very good thermal conditions, which means that this year’s Typhoon Xuanlanno has such strong winds, lasts for such a long time, and involves a wide range of risks, all of which are inseparable from extreme high temperature weather. In response to Xuan Lannuo, China Eastern Airlines tied up its aircraft at Hongqiao Airport. How powerful will this typhoon be?

Affected by Typhoon No. 11 this year, Xuanlannuo, more than 100 flights in and out of Shanghai have been cancelled.

As the super typhoon Xuanrano advances strongly in the eastern sea area of ​​​​my country, all aspects of our country are strengthening response. At the Shanghai Hongqiao Airport Eastern Airlines Hongqiao maintenance base, according to the requirements of the technology company, for the Hongqiao Airport The Boeing 737 aircraft that have been discontinued have implemented flow restriction measures, and at the same time, some facilities on the apron have been fixed. The mooring operation is mainly to connect and fix the ground anchor on the apron ground and the connection point of the aircraft landing gear through mooring cables, so that the aircraft body can be kept stable under the action of the ground anchor and mooring rope lock. To put it simply, it is to tie the aircraft to the ground with ropes.

The impact of typhoons on aircraft is huge. Aircraft fly by relying on the lift generated by air flowing over the upper and lower surfaces of the wings. Even if the aircraft weighs dozens of tons, strong winds of more than ten levels blowing over the wings will generate huge lift and move the aircraft, causing risks such as collisions. Therefore, aircraft tethering is a very critical protection measure.
