The truth about the weather

The scientific principles involved are as follows:

Domestic chickens like to be dry. Before it rains, the water vapor is thick, and the chicken cage is particularly humid and sultry, so they don't want to enter the cage early.

Every time the weather gets worse, the water vapor in the air increases and the air pressure decreases. Too much steam makes the soil wet again, so the ant nest is particularly wet. Because the air pressure decreases, the dirty air accumulated in the original dust in the soil escapes, so ants rarely live in their nests.

Proverbs containing scientific truth:

1, early rainbow rain and late rainbow sunny.

The rainbow appears in the opposite direction to the sun. In the morning, the sun is in the east and the rainbow is in the west. In the afternoon, the sun is in the west and the rainbow is in the east. Because the weather system moves regularly, it moves from east to west and a rainbow appears in the west. It shows that the thunderstorm area in the west will move, there will be rain in the local area, and there will be rainbows in the east, which means that the rain area will move eastward and will not affect the local area. So it is also called "East Rainbow Sun, West Rainbow Rain".

2, fish scales, no rain and no wind.

In the blue sky, you can sometimes see neat and tight white clouds, like fish scales, which are called cirrocumulus in meteorology. Cirrocumulus usually appears at an altitude of more than 5,000 meters, and can only last for a few minutes to more than an hour after its formation. The appearance of this cloud indicates that a trough of low pressure is moving above the ground. The weather affecting the ground generally depends on the atmospheric movement at high altitude. Therefore, when cirrocumulus appeared, it was the time when sunny days turned to rainy days. "Fish-scale days, even if it doesn't rain, the wind will jump", which is a sign of wind and rain. Usually there will be wind and rain in a day or two.

3, "tripterygium wilfordii" sing first, there is not much rain.

In summer, when the sun is shining in the sky, the ground is exposed to strong sunlight, which makes the air in some areas expand and become lighter, carrying a lot of water vapor to rise. Water vapor rises to the sky and cools, then condenses into clouds. This kind of cloud is called local convective cloud, which has a small range and moves. When convection develops violently, charged thunderstorm clouds are formed. This cloud thunders and rains in the distance, and we can only hear thunder. There were only showers nearby, but they passed quickly, and it cleared up after the rain, so there was "not much rain". Also known as "there is thunder before the rain, but it doesn't rain much".

Dark clouds catch the sunset, not today, but tomorrow.

In the evening of spring and summer, in the west of the sky, there are dark clouds standing like stone mountains to meet the sun. When the sun falls into the clouds, they can't see. The masses call it "dark clouds see the sunset." Such dark clouds refer to cumulonimbus clouds or cumulonimbus clouds, which are mostly caused by high and low pressure systems. Its movement law is generally from west to east, so it will affect local areas. So it moves at different speeds, mostly slowly, and it won't rain until tomorrow, so it's called "if it doesn't fall today, it will fall tomorrow".
