The appearance of tsunami clouds

20 10 on may 28th, a tsunami cloud appeared in Changchun, and the weather was gloomy. Experts from the Municipal Meteorological Bureau explained that this is not an "earthquake cloud" or a "tsunami cloud" at all, but a very common "stratocumulus cloud" and "altocumulus cloud". It should have nothing to do with the earthquake. The so-called tsunami cloud, the popular saying at present is that the rising cloud is forced to hang in mid-air due to the resistance of the atmospheric inversion layer, occasionally forming a strange natural phenomenon; It should be said that it is extremely rare. If you see this kind of cloud, you should feel lucky. Often, after the local "tsunami cloud" appears, it will turn from sunny to cloudy for more than half a month.

20 12 on February 28th, it was sunny in Zhongli, Taoyuan, Taiwan Province, but there was a terrible spectacle like a tsunami. A large cloud swept in and moved slowly, as if to "swallow whales" in the middle of the cave. Just like the sandstorm in the movie special effects scene, it is staggering. The film triggered a hot discussion among netizens: Is it the end of the world? According to Lin Peilian, director of the Department of Atmospheric Science at Central University, on February 28th, the north wind was originally blowing, but it suddenly turned to the south wind, and the temperature suddenly rose by 2℃ and then dropped by 4℃. Cold air meets warm wet air near the ground to produce fog, and there is a frontal convection system behind it, which constantly blows the cold air downward, and then the clouds roll, causing a scene similar to sandstorm, which is actually just a tsunami cloud formed by the frontal surface.

However, tsunami clouds are only a natural phenomenon, not a sign of a tsunami.
