Weather bubble

Let's take a look at the incident first: On July 13, Cape Town, South Africa was hit by a strong wind, accompanied by strong winds and huge waves, and the coastline appeared quite spectacular? Wave foam? . The video shows that some cars are tightly wrapped by the foam that comes from the face, as if they were caught in the fermented dough, which attracted passers-by to stop and take pictures.

So why do waves bubble when they are blown by strong winds? What is the reason? How windy was it then? As we all know, the waves will have white splash after being blown by the wind, and usually unclean water will have foam after being stirred. By analogy, high-intensity rotation or strong wind is very likely to foam the waves. 7. 12, a continuous cold front hit Cape Town, accompanied by heavy rain and floods. The wind speed is as high as 100 km per hour and the wave height is as high as 10 m. Wave foam? Created conditions for the emergence. Under the condition of high wind speed and huge waves, Shanghai has a high content of organic matter, so the sea water is very easy to turn into foam, and then it is brought to the shore by the huge wind, which has a serious impact on people on the other shore.

In addition to the above speculation, some netizens have provided another statement, that is, there are many microorganisms in seawater, so the content of protein is high. The strong wind stirred it and made it fully mix with the air, forming a large number of? Protein foam? . Generally speaking, the two statements are similar. Microbes and organic matter are prone to foam after stirring, especially under the strong wind with speed 100 km. In fact, besides South Africa, there are also cities in China? Wave foam? . The salt lake in Yuncheng, Shanxi Province, also produces many bubbles when it is windy, just like snow. So what? Wave foam? It's not unusual, and because the sea water is not clean, it's best not to take pictures or touch fresh ones in this situation. For the sake of your health, it is better to go out less and get together less in bad weather and spend the disaster weather at home with peace of mind.
