What are the "southern hemisphere" and "northern hemisphere" of FGO? Why are they called "Southern Hemisphere" and "Northern Hemisphere"?

Look at the solar terms first. If it is a dichotomy, it is divided into east, west, north and south by longitude and latitude. If it is the solstice, it depends on whether it is the solstice in winter or the solstice in summer. If it's the solstice in summer, it's the Antarctic where the polar night happens. At this time, the days in the southern hemisphere are short and the nights are long. If it's the solstice in winter, it's the North Pole where the polar night occurs. At this time, the days in the northern hemisphere are short and the nights are long.

The dividing line between the northern and southern hemispheres: the equator (0 parallel) is the boundary. That is, the latitude of the northern hemisphere is: 0 latitude, north latitude10 to 90 north latitude; The latitude of the southern hemisphere is 0 latitude, and the south latitude10 is 90 south latitude. The dividing line between the eastern hemisphere and the western hemisphere: it is bounded by the longitude coil of 20 west longitude and160 east longitude. That is, the longitudes of the Eastern Hemisphere are: 20 W, 0 W 10, 0 E, 0 E 10 to 0 E160; The longitudes of the western hemisphere are: 20 W, 30 W, 40 W,180 e,170 e to160 e. ..

The southern hemisphere is half the earth between the Antarctic and the equator, and the southern hemisphere is south of the equator. Antarctica lies near the South Pole. Brazil and Australia are the two largest countries in the southern hemisphere. Most of Oceania and South America are in the southern hemisphere. Indonesia in Asia is located in the southern hemisphere because more than 70% of its territory is located in the southern hemisphere. East Timor is the only Asian country whose entire territory lies in the southern hemisphere. Africa is the continent with the largest number of countries in the southern hemisphere.

The northern hemisphere refers to the area north of the equator of the earth. All the people in the northern hemisphere are North America and Europe. In this hemisphere, land accounts for 39.3% and ocean accounts for 60.7%. Winter in the northern hemisphere is usually 65438+February to February, and summer is usually June to August, which is contrary to the four seasons in the southern hemisphere. The two most widely distributed climates in temperate regions of the northern hemisphere are: temperate continental climate and sub-frigid coniferous forest climate.
