The beginning of winter season information on books

The beginning of winter to introduce

"The beginning of winter" throttle on November 7 or 8, China's ancient folk habits at the beginning of winter to the beginning of winter, our country is vast, in addition to no annual winter in the south China coastal and the qinghai-tibet plateau long summer without winter, winter is not all around in winter at the same time began.

According to the classification standard of the four seasons of climatology, syndrome in the second half of the average temperatures fall below 10 ℃ for the winter, is "the beginning of winter for the beginning of winter" climate law of huanghuai region.Most at mohe and north of the greater hinggan mountains in the north of China, has already entered the winter, in September in late October the capital, Beijing has also is a scene in the winter, and the Yangtze river in winter to "light snow" before and after the throttle really begins.

date

"The beginning of winter" throttle on November 7 or 8, a formula (Y * D + C) - L

Formula interpretation: Y = 2 after years, D = 0.2422, L = number of leap year, C = 7.438 in the 21st century, the 20th century = 8.218.

For example: in 2088, the beginning of winter date = [88 x 0.2422 + 7.438] - [88/4] = 28-22 = 6, November 6, is the beginning of winter.

Exception: the calculation results and 1, 2089.

The climate characteristics

Astronomy, "the beginning of winter" as the beginning of winter, in accordance with the climatology classification, our country should hold off winter 20 days or so.The beginning of winter season, the sun has reached 225 degrees longitude, we are in the northern hemisphere receive the sun's radiation is less and less, but due to the surface in summer half year at this time there is a certain energy storage quantity of heat, so usually isn't too cold, but the temperature gradually decreases.On a clear there is no wind, often appear beautiful, warm and comfortable "Indian summer" weather in October.

Before and after the beginning of winter, a significant reduction in precipitation in most areas of China.Frozen earth northeast area, the crops into the over-wintering stage;Jianghuai region "sowing and ploughing" is nearing an end.Jiangnan is busy busy planting crop system later, grasping the transplanting rapeseed;While southern China is right "the beginning of winter wheat planting" best time.The stand or fall of water condition and crop seedling stage growth and the winter has a very close relationship.North China and huanghuai region should in down to 4 ℃, the average daily temperature field of frozen soil eve day disappear, take time to water the good of winter wheat, vegetables, and orchard, water supply insufficient soil moisture, improve the field microclimate environment, prevent "drought help cold", reduce and avoid the happening of the cold.In south China and south China region, a good field "FengChanGou", good drainage, prevent freezing winter waterlogged and harm of the important measures.In addition, after the beginning of winter air generally become dry, less soil water, forest fire prevention work should also be on the agenda.

Tropical air turning a spent force

According to statistics, the average every year in November have 2-3 tropical air generated by turning.Especially in the northwest Pacific Ocean turning generated gas, still possible to develop the typhoon intensity.Almost 55 years, November 11 tropical air turning coastal login in our country, login location mainly in Taiwan, guangdong and hainan.If the prevalence of mid-latitude zonal circulation, tropical air turning is more active, if the prevalence of mid-latitude meridional circulation, is the strong cold air, it is not easy to have a typhoon.

South China autumn and summer

During the beginning of winter in the north of south China, even the wind swept, the temperature quickly recover, sunny, no wind is "the October Indian summer, warm wind".Here are 12 month will enter the winter.

South China, Taiwan as well as in the south of hainan island in southern district, has yet to enter the winter in November.But the temperature is not high in November, the highest temperature is generally below 30 ℃.In addition, does not rule out a strong cold air, the influence of a strong cooling, just less frequent in recent years.

Late autumn winter easy to frost

In a normal year in November, north qinling mountain and huanghuai south and west, south to northern jiangnan will gradually appear first frost.Slant cold years, in mid-november, also can appear first frost north of nanling.

November north, along with the cold air forward out of the local, feng began to warm the cold air group's side after the degeneration, if there is no subsequent air added, after a few days, the temperature has rebounded, air quality has worsened.Especially in big cities, the accumulation of water vapor in the atmosphere and pollution particles in combination with coagulation, smoke or fog formation, influencing the health of people and traffic.In China's southwest, south, water vapor condition is better than the north, if temperature is low in the morning, into the fog often occur.

The first snow in north China rainfall varied

After November, precipitation decreased significantly across the country.Melting snow is no longer on the plateau snow mountain.Tend to appear first snow in places such as north China, Beijing's first snow difficult to forecast, the influence is big, often require special attention.At this point, the precipitation in the form of diversification: rain, snow, sleet, hail, ice, etc.When there is a strong cold air influence, the jiangnan alsoIt snows。

In the southwest of typical huaxi sounds over, but relative to the national basic less rain, it rains a lot in it's place.According to the time distribution of precipitation, southwest into the dry season of the year in November.The characteristics of the southwest northwest dry season more obvious.Southwest sichuan basin, eastern guizhou, yunnan, in November and rainfall of more than 50 mm.In yunnan, the warmth of sunshine, rain, cold, there is "four spring-like, a rain and winter".If you encounter strong cold air invasion, warm moist air flows have echo, southern region the process of rainfall will also bigger.At this point, the north of the Yangtze river and the rain days and rainfall in south China, fewer than in the jiangnan region, three rare south China for a year, the drought in November, there are still negative effects on crops growth.

Drop in temperature change is obvious

Along with the strengthening of the cold air, the temperature decline faster.The cooling in the north, people become accustomed to.Starting in late October, heating, people may have a cold weather.For at this time in the late autumn "enjoying" the people of the middle and lower reaches of the Yangtze river region, the average temperature is usually 12 ℃ to 15 ℃.Continous rain is over, if you have strong cold air moved quickly, sometimes less than a day time, cooling can nearly 8-10 ℃, and more.But, after all, after the wind, the sun shines, cold quickly degeneration, the rise of temperature quickly.Temperature recovery and the accumulation of heat, make the next round of bring strong cold air cooling.At this point, the autumn weather is pleasant, draws to a close, obvious cooling make in this area into the frost season at the beginning and at the same time, also entered the red leaves best viewing period, and at the end of November winter in succession.

Northerly winds more wind to strengthen

As a long winter, north China, northeast, northwest, cool wind, can be said to be used at this time.In south-central north China to huanghuai, the cold air during the beginning of winter, often not of wind swept the mountains in this area and the red light, is the city tree is blown into the polished rod, let people have a feeling of suddenly into the winter.If encounter force strong, the speed of the cold air, and it ran all the way, make the mountain pass north and south of the river's lake river wind, wind blows to the southeast coast and Taiwan strait.Especially in the northern, eastern waters, the sea wind is easy to make homework suffer heavy loss at sea.

Temperature difference between the koreas

Our country is a large country, and north and south across dozens of latitude, and consequently existence north-south temperature difference.But after the beginning of winter more widening north-south temperature difference.In November, China's most of the qinghai-tibet plateau, Inner Mongolia and heilongjiang north, the average temperature has reached - 10 ℃ or so.The most northern at mohe and hainan haikou, the temperature difference can be up to more than 30 ℃ to 50 ℃.Many places in the north is dry dry, dreariness and chill;And is still the mountains of southern China, charactizing a fine spring day, warm and pleasant.
