The lines and opening remarks of the weather forecast host

An autumn rain and a cold, the four seasons are sunny and cold, all in the "Meteorological Encyclopedia", hello everyone, I am today's meteorological anchor _ _, from the first experimental primary school in wuxiang new district, Nanning; Today is Sunday, 10, 18, the second day of the ninth lunar month. Today, let's talk about foggy days. First of all, I will share with you a short story about foggy days: "Grass Boat Borrows Arrows".

It is said that Zhou Yu was jealous of Zhuge Liang's talent over himself and came up with a plan to kill Zhuge Liang by surprise, demanding that Zhuge Liang build 100,000 arrows within ten days. Zhuge Liang accepted it gladly and made a written pledge to fulfill a military order, shortening the time to three days. In fact, Zhuge Liang has answers. He has calculated that there will be heavy fog on the Yangtze River in three days.

According to meteorology, there are two kinds of common fog: one is advection fog, which is the fog formed when warm air meets cold air. It is characterized by a wide range and is not easy to disperse. The second is radiation fog, which is the fog formed by rain during the day and clear at night, high ground humidity and air heating flow radiating to the ground. It is characterized by a small range, and the sun will disperse when it comes out.

Compared with the north, the winter climate of the Yangtze River is rainy, humid and hot, and it is easy to form radiation fog.

Zhuge Liang used radiation fog as a bunker. Seeing that Cao Cao did not dare to attack rashly in the fog, he could only "shoot arrows at random" and "borrowed" 100,000 arrows from Cao Cao with great confidence.

Well, I believe that through the sharing of this short story, everyone will know more about "fog". Finally, I hope everyone has a warm coat and a warm heart this winter.
