Will the typhoon express stop?
Typhoon has a great impact on the logistics industry, from customer delivery and parcel safety to delayed delivery time and personnel safety. The wind speed of typhoons is mostly above 17m/s, even above 60m/s ... According to the measurement, when the wind reaches 12, the wind pressure per square meter on the plane perpendicular to the wind direction can reach 230kg. Therefore, when the super typhoon comes, the strong wind and the huge waves caused by it can throw up or even smash the coastal ships, and also push the huge ships inland.
If you encounter extreme weather, the express delivery will be affected. For example, if a place encounters bad weather and the main traffic roads are controlled or affected, then the express delivery cannot be transported normally. Therefore, when weather factors such as lightning, rainstorm and typhoon affect the delivery, it is likely to be delayed. In this bad weather, traffic trunk lines will be affected, from temporary traffic control to infrastructure damage. Therefore, the impact on express delivery is inevitable.
Brief introduction of typhoon
According to its intensity, typhoons can be divided into six grades: tropical depression, tropical storm, strong tropical storm, typhoon, strong typhoon and super typhoon. The formation of typhoon requires the following conditions: the sea surface water temperature is above 26.5℃, the initial disturbance of positive vorticity is certain, the vertical shear of environmental wind is small, and the low pressure or cloud disturbance is at least several latitudes away from the equator. Typhoon is a deep low-pressure system, and its central air pressure is very low. There is an air flow converging towards the center at the lower level, and the air flow at the upper level mainly diverges outward.
Typhoons often bring strong winds, heavy rains and storm surges, which not only bring disasters to human beings, but also bring benefits to human beings. Typhoon has brought abundant fresh water resources to human beings, which is of great significance for improving fresh water supply and ecological environment. In addition, typhoons also keep the global cold and heat relatively balanced; The climate in the equatorial region is hot. If the typhoon does not disperse this heat, the tropics will be hotter, the frigid zone will be colder and the temperate zone will disappear from the earth.
