In response to Xuan Lannuo, China Eastern Airlines tied up a plane at Hongqiao Airport. How bad will this typhoon be?

This year's typhoon Xuanlannuo (1 1) is the super typhoon 1 in 2022. The typhoon with such a strong wind is inseparable from our extreme high temperature weather around the world this year. The extremely hot weather has spread all over the world this year. Not only in China, but also in many western countries, it is deeply affected by extreme high temperature weather.

This year's hot weather is particularly prominent in Sichuan and Chongqing. High temperature weather, under the atmospheric circulation situation, the negative high pressure anomaly from the northwest Pacific is the main reason for the continuous high temperature weather. The influence of this extreme high temperature weather also easily leads to a cautious downward flow, which makes the sea surface temperature rise to a certain extent. At this time, a lot of heat will gather at sea, which will form good thermal conditions for this year's typhoon. In other words, this year's typhoon "Xuanlannuo" has such a strong wind, such a long duration and such a wide range of risks, which are inseparable from extreme high temperature weather. In response to Xuan Lannuo, China Eastern Airlines tied up a plane at Hongqiao Airport. How bad will this typhoon be?

Affected by typhoon 1 1 this year? What about Xuan? As a result, more than 100 flights in and out of Shanghai were cancelled.

With the strong promotion of super typhoon "Xuanlannuo" in the eastern waters of China, all aspects of China are strengthening their response to the Hongqiao maintenance base of China Eastern Airlines at Shanghai Hongqiao Airport. According to the requirements of the technology company, the Boeing 737 aircraft discontinued at Hongqiao Airport has implemented current limiting measures, and some facilities on the apron have been repaired. ? Tied? The operation is mainly to connect and fix the ground anchor on the tarmac ground with the connection point of the aircraft landing gear through the mooring line, so that the aircraft fuselage can be kept stable under the action of the ground anchor and the mooring lock. Simply put, it is to tie the plane to the ground with a rope.

The impact of typhoon on aircraft is enormous. Airplanes fly by the lift generated by air flowing over the upper and lower surfaces of wings. Even if the plane weighs tens of tons, more than a dozen strong winds blowing on the wings will generate huge lift to move the plane, causing risks such as suspension and bumps. Therefore, aircraft mooring is a very critical protective measure.
