What is the Arctic like in spring, summer, autumn and winter?

The North Pole, like the South Pole, has extreme days and nights, and the closer you get to the North Pole, the more obvious it is. Winter in the Arctic is long, cold and dark. From165438+1October 23rd every year, there will be days when the sun can't be seen at all for nearly half a year. The temperature will drop to MINUS 50 degrees Celsius. At this time, all the waves and tides disappeared, because the coast was frozen, and only the wind swept around wrapped in snow.

In April, the weather gradually warms up, the snow and ice gradually melt, and large pieces of ice begin to melt, break and collide, making a loud noise; There is gurgling water in the stream; The sky becomes bright and the sun shines on the earth.

In May and June, plants are covered with the green of life, and animals become active and busy reproducing. In this season, animals can get enough food and accumulate enough nutrition and fat to spend the long winter.

Autumn in the Arctic is very short. In early September, the first snowstorm is coming. The arctic soon returned to the cold and dark winter.

In the Arctic, the sun will never rise high in the sky, even in midsummer, its rising angle will not exceed 23.5 degrees. The annual precipitation in the Arctic region is generally 100 ~ 250 mm, and the Greenland sea area can reach 500 mm. Precipitation is concentrated in offshore land, and the most important form is summer rain.

Winter in the Arctic Ocean lasts for six months from June 1 1 to April of the following year. May, June, September and 65438+ October belong to spring and autumn. In summer, it only lasts for seven or eight months. The average temperature in June+10/October in 5438 was between -20℃ and -40℃. The average temperature in the warmest August is only MINUS 8 degrees. The lowest temperature measured by the drifting station near the pole of the Arctic Ocean is -59℃. Due to the influence of ocean currents and Arctic anticyclones, the coldest place in the Arctic is not in the middle of the Arctic Ocean. The lowest temperature recorded in Yansk, Vilho, Siberia was 70℃ below zero, and the prospectors in Alaska also recorded 62℃ below zero.

The closer to the pole, the more obvious the meteorological and climatic characteristics of the polar region. There is only one day and one night a year. Even in midsummer, the sun just hangs on the distant southern horizon, with a bleak white light. The sun never rises more than 23.5 degrees, and it moves slowly around this endless white world quietly. A few months later, the sun's trajectory gradually approached the horizon, so the evening season in the Arctic began.
