Experts say that it is particularly cold in Shaanxi this winter or now. Is there any scientific basis for this conclusion?

In fact, Shaanxi enjoys a superior geographical position, which is located in the middle of Chinese mainland. China's north-south dividing line, the Qinling Huaihe River, does not pass through the south of Shaanxi, so Shaanxi is a northern province as a whole, but a small part belongs to the south.

Because Shaanxi is inland, the four seasons are quite distinct. Although it is a northern province, the temperature in winter will not be so low because the latitude is not particularly high. However, because there may be a northwest wind blowing from Siberia in a few days, the temperature will drop very low, and the overall global temperature has been rising in recent years, so the winter in Shaanxi is not particularly cold in recent years. In summer, the temperature in Shaanxi is relatively high. Because it is inland, there is less precipitation, and once there is precipitation, it will be particularly concentrated. Another obvious feature is that its spring and autumn are particularly short. Generally, it takes less than ten days in spring or autumn.

But it often rains in Shaanxi from August to September this year, and it lasts for many days. People often say that an autumn rain brings a cold. Of course, the more rain in autumn, the faster winter. Therefore, the rainfall in Shaanxi during that period also had a great impact on the recent cooling. Recently, people in many places in Shaanxi have put on down jackets, and citizens in cities a little farther south have also put on thick clothes.

What is particularly different from previous years is that the cooling has come very quickly. According to the historical data of previous years, such cold weather will not appear until 165438+ 10. Therefore, according to the climate change a while ago, meteorologists speculate that it may be very cold in winter in Shaanxi this year, which is certainly scientifically based. Therefore, under such cold conditions, the elderly and children should do a good job of keeping warm.
