Why is it always so sunny before the storm comes?

If you don't go out at sunrise, you will travel thousands of miles at sunset. In a relatively stable climate, the sunset will travel thousands of miles, which indicates fine weather. When the morning glow is all over the sky, there is a great possibility of rain. Cirrus clouds appear in the sky, that is, the clouds show a pure white ponytail shape, but gradually turn dark, which means that it is sunny now, but it may rain a day later. Cumulus clouds appear in the sky, that is, the clouds are dark and thick, which indicates that there will be thunderstorms and strong winds. There is a thin cirrostratus in the sky, and it may rain after half a day. If there are no more clouds around the hills, people will feel less depressed, indicating that it will not rain in the short term.

distinguish the weather from the behavior of animals.

Signs of fine weather 1. A sparrow is very sensitive to weather changes when it chirps in Massachusetts in the morning. The better the weather, the worse the barking. 2. An increase in lark calls indicates a sunny day-a lark's brisk call from a distance can prove that it is a good weather with dry air. 3. In the morning, there are water droplets on the spider's web, which means it is sunny-on a sunny day, the temperature is low in the morning, which makes the water vapor in the air condense into small water droplets and flicker on the spider's web. Usually it won't rain.

a sign of rain. Frogs chirping and swallows flying low are omens before rain. There are also several kinds: 1. Ants cross the road-ants who dig holes in the ground and live, feel that it will rain and the holes will flood, that is, they will run away before it rains. 2, the earthworm out of the hole-the ground is wet and soft, and the earthworm will climb out of the ground, indicating that it will rain. Before it rains, there are signs that mosquitoes cluster, rain ants appear in groups, and cats wash their faces.

Signs of bad weather:

1. The wind in the valley blows from the top of the mountain to the valley during the day and from the valley to the top of the mountain at night

2. Silk clouds appear in the morning, and then black clouds increase, and slowly sink

3. Clouds move quickly and tend to increase, which is a precursor to the storm

4. The wind direction suddenly changes and blows harder. Suddenly, the visibility improved

6. The fog filled the valley in the morning, but it didn't dissipate at night

7. There was a big halo around the sun during the day and a small halo around the moon at night, which was a sign of strong wind

8. The stars flickered before dawn

9. The temperature increased in the evening, and it was warm at night, with a sultry feeling

1. Clouds in the semi-valley rose, which may be. Nature and wildlife will also change, and if you pay attention to observation, you can also predict the future weather conditions

Sound and smell: when the air humidity increases, the sound will travel farther and the smell will be easier to distinguish-saturated wet air is like an amplifier, which is a good conductor. For example, you can't hear the sound of the train running in some places, but you can clearly hear the sound of the train before it rains on a certain day.

Physical changes: When the weather gets worse, curlers will feel that their hair is getting tighter and harder to comb-just like animal hair, if it becomes easy to wind or is not as straight and easy to comb as usual, it will probably be a storm. Anyone with rheumatoid arthritis, corns or related symptoms will feel pain and discomfort when the air humidity increases.

Observe the bonfire: If the fireworks rise steadily, it means that the weather will not change much, and it will still be fine. If the fireworks flicker, or rise and fall, there may be a storm on the right.

when the weather is fine, the temperature difference between day and night changes greatly, and the water vapor in cold air will turn into small water droplets or frost, so the colder the night, the better the weather will be the next day, and there will be dew at night. If you see water droplets on the spider web in the morning, it will clear up, and if you see frost in the morning, it will indicate another good weather.
