What's the difference between the weather in the United States and that in China?

There is not much difference. The four seasons are the same, belonging to the northern hemisphere, with similar latitudes and the same seasons, but there are some differences in climate types. China has subtropical monsoon and temperate monsoon. However, the Gulf Coast in the south of the United States and the Atlantic Coast in the southeast belong to subtropical humid climate.

However, the time difference between US Eastern Time and China Beijing Time is only 12 hours, and the time difference between US Western Time and Beijing Time is 15 hours.

Seasonal reasons:

The fundamental reason for the seasonal change is that the earth's axis of rotation is not perpendicular to its orbital plane, and the deflection angle is 23 degrees and 26 minutes (the angle of ecliptic). In different seasons, the solar illumination received by the northern and southern hemispheres is unequal and changes periodically.

The sunny hemisphere is summer and the other half is winter. Spring and autumn are transitional seasons. When the direct point of the sun is close to the equator, the sunshine conditions in the two hemispheres are similar, but the trend of seasonal development is still opposite-when it is autumn in the southern hemisphere, it is spring in the northern hemisphere.

The division of astronomical seasons is determined strictly according to the position of the earth's revolution, but due to the climate, the actual seasons in different regions are different. There are many ways to divide the four seasons, and the following four are the most common (taking the northern hemisphere as an example):

In China, the tradition of dividing the four seasons into four stops is the starting point, beginning of spring is the starting point of spring, and so on. In the west, bisection is the starting point of dividing the four seasons, vernal equinox is the starting point of spring, and so on.

According to the standard of climate itself-waiting temperature (average temperature of five days), summer is divided into continuous periods with average temperature above 22℃. Winter-a continuous period when the average temperature is below 10℃. The period between Spring and Autumn-10 and 22℃.
