Is it expected to be cold in winter 2018? Another winter, there has been a large area of snowfall in the northern region. Many people think that this year's snowfall is so early, will it be cold this year? The meteorological department analyzed the winter temperature in 2018. In theory, this year is a warm winter.
There was an El Nino this year
At present, most of northern China has entered winter. In terms of the current climate, the winter in 2018 is not cold, it is a normal climate, and may be warm.
Because of the El Nino phenomenon in the Pacific this year, some people think that La Nina is coming, and the climate will be very cold this year. However, there is no basis for this conjecture. You may not know these two phenomena very well. The duration of these two kinds of sites will be relatively long, so even if they are affected, they will also affect climate warming. That is to say, the temperature in most areas of China is expected to be high in winter, and the possibility of cold winter is unlikely.
Generally speaking, when the average temperature of the whole winter in a certain region from December to February of the next year is 0.5 ℃ higher than that of the whole year (the annual value is generally taken as nearly 30-year average, and China started to use the 30-year average value from 1971 to 2000 as the annual value according to the WMO regulations since 2002), it is called warm winter, and it is called cold winter if it is higher than 0.5 ℃. When the temperature of this period is 0 ℃ - 0.4 ℃ higher than that of the whole year, it is called "slightly higher" in meteorology, and "slightly lower" when it is 0 ℃ - 0.4 ℃ lower.
Therefore, warm winter and cold winter refer to the temperature of the whole winter, rather than the temperature change of a certain day or a certain period. Warm weather may occur in cold winter, and very cold weather may occur in warm winter.
Recent weather conditions after winter in North China in 2018
From 15th to 17th, the strong cold air moved eastward and southward and affected the North China, Northeast China and Huanghuai region.

There are 4-6 northerly winds in the east of Inner Mongolia, Gansu, north of Shaanxi and north of North China. The temperature drops 6-8 ℃, and the local cooling range can reach more than 10 ℃. From the day of 15th to the night of 16th, there will be 6-7 class winds and 8 class gusts in the sea area of the south of Yellow River and the north of the East China Sea.
