What weather phenomenon is called the natural enemy of aircraft?

Thunderstorm weather is called the natural enemy of aircraft.

Thunderstorm is a local strong convective weather visible in tropical and temperate regions. Thunderstorms may be accompanied by lightning, lightning, strong winds and heavy precipitation, such as rain or hail. Thunderstorms can occur in spring and summer, and common examples are summer afternoons, or they may occur together with winter snowstorms. This is called thundersnow.

The duration of thunderstorm is usually less than 2 hours, and its life cycle includes cumulus stage, maturity stage and dissipation stage. Mature thunderstorms are characterized by highly developed cumulonimbus clouds. The convection center moves strongly upward and the surrounding area moves downward, which can form downburst and squall front. Thunderstorms bring about drastic changes in the weather and may become meteorological disasters.

generative mechanism

Cumulonimbus clouds that form thunderstorms develop vigorously, and there are often ice crystals on the upper part of the clouds. The attachment of ice crystals, the breaking of water droplets and air convection make clouds generate charges. The distribution of charge in the cloud is very complicated, but in general, the upper part of the cloud is mainly positive charge, the middle and lower part of the cloud is mainly negative charge, and there is a small positive charge area in the strong updraft in front of the lower part of the cloud.

There is a potential difference between the top and bottom of the cloud. When the potential difference reaches a certain level, discharge will occur, which is the usual lightning phenomenon. In the process of discharge, the temperature in the flash path suddenly rises, which makes the air volume expand rapidly, thus generating shock waves and leading to strong lightning. When the clouds are very low, sometimes a discharge between clouds can be formed, which is lightning strike. Therefore, thunderstorm is the product of atmospheric instability, and it is the general name of cumulonimbus clouds and their accompanying disastrous weather.
