Will the recent cold weather affect the take-off and landing of aircraft?

Cold wave weather is different from ordinary weather, which has a great impact on civil aviation flight and passengers' personal safety and cannot be taken lightly. The first is the influence of cold wave and strong wind. When there is a cold wave, the first manifestation is cold wave and strong wind. Because of the strong cold air going south, there are strong winds everywhere. Generally, the average wind speed can reach more than 15m/s, the gust can reach more than 25 m/s, and the wind direction is mostly from northwest to west wind, which lasts for a long time, usually for several hours to more than ten hours, and sometimes for more than two days. If the cold wave and strong wind form an angle of more than 45 degrees with the runway, the large crosswind angle will complicate the take-off and landing of the aircraft. When taxiing in the crosswind, the forces on the two wings of the aircraft are different. The lift of windward wing increases, while that of leeward wing decreases, resulting in the tilting moment. In addition, because the crosswind pressure center does not coincide with the center of gravity of the aircraft, it will also produce a turning moment that makes the aircraft rotate in the headwind direction. When the crosswind is very strong, and the reaction force of the runway to the wheels is opposite to the turning moment, which is not enough to keep the plane balanced, the nose will deflect to the crosswind direction. Therefore, when the plane is running in the crosswind, the captain always presses the joystick in the crosswind direction to eliminate the tilting moment, and boards the rudder in the opposite direction to eliminate the turning moment. It is more difficult for an airplane to land in a crosswind than to take off. At this time, the captain must pay attention to correct the drift. If it is not corrected properly, the plane will be grounded in different places. When an airplane lands in a strong crosswind, accidents such as tire breakage and landing gear breakage are likely to occur, which seriously endanger the safety of the airplane and passengers. Therefore, because the crosswind is too strong and exceeds the conditions, the airport is closed from time to time. Secondly, the influence of cold wave precipitation. Due to the sudden invasion of strong cold air and the violent impact on the warm and humid air in front, there are often heavy showers or snowfall at the front of the cold wave. Due to precipitation, the humidity in the lower layer increases sharply, which is easy to produce low-broken clouds, sometimes only tens of meters, and the height of the cloud bottom fluctuates greatly, which seriously affects the take-off and landing of aircraft. At the same time, due to the sudden precipitation, the visibility at the lower level quickly deteriorated. When the visibility is lower than the captain's takeoff and landing standard, the plane cannot take off and land. In addition, in southern China, due to the active warm and humid air in spring, when there is a cold front, it is easy to produce strong convective weather, and thunderstorms pose a great threat to flight routes and aircraft take-off and landing. There is also icing on the runway that endangers the safety of aircraft taking off and landing. As the cold wave just invaded, it produced precipitation, and then strong cold air came, and the temperature dropped sharply, which quickly frozen into ice on the runway. The friction between aircraft tires and ice is very small, so it is difficult to keep the direction of aircraft taking off and landing on the icy runway surface, and it is easy to rush out of the runway. The flight manual stipulates that when the runway is frozen, it is forbidden for planes to take off and land. Due to the invasion of cold wave, it is often accompanied by heavy snowfall. If it is not cleared in time, it will also affect the take-off and landing of the aircraft.
