What are the climatic characteristics of the northern hemisphere?

China is located in the northern hemisphere of the earth, where most of the land and population are located. The northern hemisphere refers to the hemisphere north of the equator of the earth. In this hemisphere, land accounts for 39.3% and ocean accounts for 60.7%.

1, the characteristics of the northern hemisphere

Most of the land on the earth (most of Asia, the whole of Europe, the northern half of Africa, the northernmost part of North America and South America) and population are in the northern hemisphere. The northern hemisphere is home to most economically and militarily developed countries in the world, such as China, the United States, Japan, Britain, Germany, France, Denmark, Norway, Sweden, Italy, the Netherlands, Spain and Portugal. In the northern hemisphere, winter 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 oceans in the northern hemisphere include the North Pacific Ocean, the North Atlantic Ocean and the Arctic Ocean.

2. Climate in the Northern Hemisphere

According to the inclination of the earth's axis, winter in the northern hemisphere begins in beginning of winter in the twenty-four solar terms and ends in March 2 (about March 20). Summer begins in the long summer and ends at the vernal equinox in September (about September 2 1). The northernmost part of the northern hemisphere is the Arctic Circle, and the North Pole is the northern end of the Arctic Circle. Its seasons can be roughly divided into winter and Leng Xia is cold, and the average temperature is lower than other areas.

In winter, the Arctic will encounter the situation that the sun is below the horizon for one day or more, which is called extreme night. In summer, the sun will be above the horizon for one or more days in a row, which is called an extreme day. This situation lasts at least one day in the Arctic Circle, and it can last for several months in areas close to extremes.

The area south of the Arctic Circle and north of the Tropic of Cancer is a temperate zone in the northern hemisphere. Compared with the Arctic region, its temperature changes are mild, and extreme cold and extreme heat are rare. However, this mild climate is also prone to unpredictable weather. The climate in the tropical region of the northern hemisphere (south of the Tropic of Cancer and north of the equator) is often very hot all year round.

Generally speaking, it is rainy in summer and dry in winter. In the northern hemisphere, large objects passing through or above the ground level will move clockwise under the action of Coriolis force. Large air currents or ocean currents will do the same in the northern hemisphere, and the ocean currents in the North Pacific Ocean and the North Atlantic Ocean are the best examples. In the southern hemisphere, the direction is just the opposite.
