What season is winter?

Winter is one of the four seasons. The northern hemisphere usually appears in 65438+February, 65438+ 10 and February, and the southern hemisphere appears in June, July and August. Winter is characterized by low temperature and cold weather. In most areas, the days get shorter and the nights get longer in winter. Due to the inclination of the earth's orbit, a certain area of the earth is far away from the sun in winter, so it receives less solar radiation, which leads to the temperature drop. Due to different geographical locations, the climate characteristics in winter are also different. In cold areas, winter can be very cold, the temperature is below freezing point, and there is a lot of snowfall and freezing. In warm areas, the temperature in winter may still be higher, but it is still cooler than other seasons. Winter is the season when everything is dormant and collected. The growth activities of plants slow down or stop, and animals also enter the stage of hibernation or migration. People usually wear heavy clothes to keep warm in winter, and at the same time increase their calorie intake to cope with the cold weather.
