What causes the blue tears in Pingtan Island?

2065438+09 April 26-28 Blue tears can be seen even at Longfengtou Beach, and the magnitude is very large, which is rare in recent years. After returning home on May Day, Xiaobai learned from her mother that it was not only southerly wind but also foggy weather in those days, which caused blue tears. During May Day, every day is a day to the north, which greatly reduces the probability of blue tears. In addition, the weather and temperature are not very suitable, and the weather around 20 degrees is the most prone to blue tears, so it is also expected that there will be no blue tears during May Day.

Blue tears usually appear after 10 at night, and they can't be seen too early. Friends who want to wait had better go after 10, and then nothing will happen before 1 in the morning. During the May Day holiday, many netizens left messages on Xiaobai's official WeChat account. Most of them want to know if there were any blue tears that night. In fact, this is really fate. We can only judge from the weather and other factors, and the probability of its appearance at night will be greater, so it is impossible to accurately predict its appearance time.

Tip: Blue tears are actually a kind of microorganism, a kind of organism with its own fluorescence, also known as "ocean fluorescence". Because its body contains light-emitting glands, which is a relatively rare structure, coupled with the beating of the waves, it will produce blue light. Blue tears can only survive for dozens of seconds after being washed ashore, which can be said to be a flash in the pan. Once the light disappears, it means the end of its life.
