Why does the sun rise in the east and set in the west every day?

Time flies so fast, and before we have time to count them, the 24 solar terms are about to usher in the hottest heat of the year. The weather of the solar term is always unpredictable, sometimes sunny and sometimes rainy, the scene of half sunny and half rainy is constantly staged in different places almost every day, and the famous literary scholar Liu Yuxi of the Tang Dynasty has made a poetic description of this scene - "the sun rises in the east and rains in the west, and the road is sunny but sunny."

Seeing this, many people feel puzzled, this rain will rain, the sun will come out of the sun, how can there be this situation of half rain and half sunny, today we will talk with you about the special weather phenomenon of "sunrise in the east and rain in the west".

However, to solve the mystery of "sunrise in the east and rain in the west", we must first start with thundershowers, which are the "hotbed" for this phenomenon. Thundershowers, unlike ordinary rainfall, often "show up" in the middle of the hot summer. Because in the summer, due to the high temperature, fast evaporation, and a lot of water vapor in the air, the air will rise upwards when the temperature rises under the strong sunlight.

When water vapour rises to an altitude of more than 7-10 km, it is easy to form cumulonimbus clouds.

Cumulonimbus clouds contain a large amount of water vapor, small water droplets and ice crystals, some of which increase in size as the cloud develops, and when the updraft cannot support them, they descend. When they pass through warmer clouds, large water droplets become raindrops, and large ice crystals become snowdrops, which melt into showers. Thundershowers often occur in summer because of the intense thermal convection that produces cumulonimbus clouds, which is only prone to occur in summer.

Because of the small size of this cumulonimbus cloud, when it moves and produces precipitation, it can only form a small rain area, so that there is rain under the clouds, even heavy rain, and the rest of the clouds, because there is no cumulonimbus cloud, the sun is still shining.

Thundershowers usually occur in the summer afternoon to evening, so it is also possible to see the sunrise in the east and rain in the west, when it rains and the sun is high.

Of course, because the cumulonimbus clouds are pushed by the wind to move slowly, the corresponding rainfall areas on the ground will also move, and the positions of the rainy and sunny areas will change constantly, not one layer at a time.

It's not easy to see this change in a city full of skyscrapers, but if you have the opportunity to go to an open area, especially on a hilltop that is not covered by the surrounding area, you can clearly see the direction in which the cumulonimbus clouds are moving.

According to relevant information, because the rotation of the earth is from west to east, the sun always rises in the east and sets in the west, and if it is on Venus, it is the opposite, because the rotation of Venus is from east to west.

Because the rotation of the earth is from west to east, relatively speaking, standing on the earth, the sun rises in the east and sets in the west.

In the solar system, the earth not only revolves around the sun, and one revolution is a year, but the earth itself is also rotating, and one rotation is one day.

The direction of the earth's rotation is from west to east, because we humans live on the earth, we often do not feel this movement of the earth, but feel that all celestial bodies revolve around the earth from east to west.

The earth rotates from west to east, and people on the earth think that the sun and other celestial bodies revolve around the earth from east to west, so people living on the earth always feel that the sun rises from the east and sets in the west when the earth rotates from west to east.

The sun does not always rise due east and set due west. There are only two days of the year, the spring and autumn equinoxes, when the sun rises due east and sets due west, not the rest of the year.

Most of our country is north of the Tropic of Capricorn, and the sun rises in the east and sets in the west depending on the season and latitude. Specifically, during the winter half of the autumn equinox to the spring equinox of the following year, the sun rises from south-east; During the summer half of the year from the spring equinox to the autumn equinox, the sun rises from north-east.
