Chapter 541: There are a few dark clouds floating in the sky
"There are many fun places, but..."
He looked up at the sky and saw a few dark clouds floating in the sky:
"Today's weather is not very good. I'm afraid it will rain. It's not a good day for fun. It's better to play close by. When the weather clears up another day, can I accompany you to visit Liaodong City?"
"Humph, lie, you don't want to go with me? How can it rain today? Even if it does rain, it will only rain at night, or else in the middle of the night. Anyway, it won't rain during the day."
"how do you know?"
He started to quarrel with me on the street and said proudly: "I am... but... I specialize in studying this with a teacher. I am very knowledgeable about the weather. You have to believe me."
"What did you study?"
"Astrology and Divination."
"Then do you know what astrology is? What is divination? What does astrology divination have to do with the weather?"
"Hey, are you going to ridicule me again for not being good at academics?"
"I didn't say that. However, it will definitely not rain during the day."
How can I convince this ancient man? It seems I have to show off some of my knowledge!
"Do you know how rain is formed? Well, you will definitely say that the Rain God brings rain, or else it is the Dragon King of the East China Sea or something...wrong. Rain is caused by the sun shining on rivers, lakes, and seas, and the water turns into water.
steam.
Water vapor rises, turns into small water droplets, and finally turns into clouds. The small water droplets or small ice crystals that make up the cloud are supported by the air flow below, and the rising air flow also continuously transports water vapor from below into the cloud.
Small water droplets and small ice crystals in the clouds collide with each other during movement, and the volume will increase. The water droplets in the lower layer of the cloud gradually become larger. After the ice crystals in the upper layer of the cloud increase in size, they fall between the water droplets in the lower part of the cloud layer, and the water droplets will become larger and larger.
Come bigger.
When these water droplets are so large that the updrafts cannot support them, it will rain; when it rains, how much it rains, and many factors in all things have an impact on each other.
In the absence of scientific weather detection, people generally predict the weather based on experience. They can predict the sky by looking at the wind, clouds, thunder, fog, stars, plants, etc. "
It would take three days and three nights to finish all this.
