Are the seasons the same?

It's different. Different regions have different seasons.

1. In temperate zones, especially in China, there are four seasons in a year, namely spring, summer, autumn and winter.

In the tropics, there are only dry season and rainy season.

In the cold zone, not only in winter, but also in the north and south poles, four seasons can be divided.

In addition to temperate seasons, other climatic zones often use other climatic factors to divide climatic seasons because of their special climate. In tropical and sub-tropical areas, the annual change of temperature is small, and the seasons are often divided by the change of precipitation or wind direction, so there are dry seasons and rainy seasons; Northeast trade wind season and southwest trade wind season, etc. This method of dividing seasons is particularly common in the South Asian subcontinent. In most parts of North Africa, a year is divided into three seasons: cool season, hot season and rainy season. Near the polar regions, it is divided into two seasons, namely, summer with eternal days and winter with long nights.

Extended data:

Because the earth's axis of rotation is inclined to its orbital plane around the sun (i.e. ecliptic plane), the variation of solar radiation on the earth's surface circulates regularly once a year. Every year in the same month, all localities generally have their own climate characteristics.

1. In temperate regions, the hottest period is usually called summer, the coldest period is called winter, and the transitional period between them is called spring and autumn. For example, in temperate regions of the northern hemisphere, March-May is spring, June-August is summer, September 9- 10/October is autumn165438+1October, and 12- February is winter. In temperate regions of the southern hemisphere, September ~165438+10 is spring, June ~ August is summer, March ~ May is autumn, and June ~ August is winter.

2. In ancient China, beginning of spring, Changchun, beginning of autumn and beginning of winter began the four seasons, while many countries in Europe and North America took the vernal equinox, summer solstice, autumn equinox and winter solstice as the first days of the four seasons. Although the astronomical season has climatic significance, it does not consider geographical and weather factors.
