It's summer in the northern hemisphere, why is it winter in the southern hemisphere?

In summer, the sun in the northern hemisphere shines directly into the northern hemisphere. The sun in the northern hemisphere is high, the days are long and the nights are short, and the temperature is high. At this time, the height of the sun in the southern hemisphere is small, the days are short and the nights are long, and the temperature is low, so it is winter.

First of all, summer is one of the four seasons. In most areas, summer is a season of hot climate and possible water shortage. In addition, since most students in the world spend their summer holidays in summer, it is also a very strong tourist season. In the north temperate zone, the meteorological summer is from May 2 1 day (Xiaoman) to August 22 (midsummer); In the south temperate zone, the meteorological summer is165438+1October 2 1 (light snow in the northern hemisphere) to February 18 of the following year (rain in the northern hemisphere).

Second, winter is one of the four seasons, between autumn and spring. Astronomically speaking, it was from February to March in 65438. China used to refer to the three months from beginning of winter to beginning of spring, and also referred to the "October, November (winter) and December (wax) months" of the lunar calendar. The time in the northern and southern hemispheres is different. According to the meteorological significance, in the temperate and cold regions of the southern hemisphere, winter is in June, July and August (or May 2 1 to August 22 according to the constellation standard), in the temperate and cold regions of the northern hemisphere, winter is in the solar terms of 12, 1 and February (or according to the constellation standard/kloc-0) Westerners generally call winter the solstice and spring the winter. From the climatological point of view, it is winter when the average temperature is lower than 10℃ for five consecutive days.
