Why doesn't it snow in Shandong?

In recent years, precipitation in Shandong Peninsula is scarce, and rivers often dry up. It is common that it doesn't rain for a month in summer. It hardly snows in winter, and I didn't see it during the Spring Festival. It has only rained a little since autumn this year, and it is not expected that there will be too much snow in the east today. From the meteorological analysis, what is the cause?

Let's take a look at the recent situation. In the past 30 days (65438+1October 28th-65438+1October 26th), the precipitation in the whole North China Plain is red, which means that the precipitation in the above areas is less than 80% compared with the normal period. Therefore, the recent precipitation in Shandong is seriously less.

As of today (165438+1October 27th), the first snow in the second half of this year has not come to Shandong. The Shandong Peninsula, that is, Yantai and Weihai, ushered in the snow in early winter this year on June 165438+ 10/8, and even some sunshine fell. This is a typical cold current snowfall. What is cold current snowfall? Generally speaking, we say that rainfall and snowfall are a combination of cold and warm air currents. The reason why it doesn't snow in Shandong is mainly because of poor water vapor conditions. However, this problem does not exist in Shandong Peninsula. When cold air blows through the Bohai Sea, it brings wet air from the sea surface to the land, resulting in snowfall. Therefore, Yantai and Weihai have their own water vapor due to their unique topography. Didn't the water vapor in your south reach me? There is a sea in the north of Laozi, and it can snow! Therefore, Yantai and Weihai, also known as snow nests, are very spectacular, windy and snowy, although they are covered with ice and snow.

On 28th-30th, a cold air affected the north. This time, Shandong mainly drinks wind to cool down. It may snow in two areas. The first one is the peninsula, especially Weihai, so there is light rain and snow on Peninsula 28. 65438+February, 1, there was a snow shower on the peninsula. The second film is in the west of Shandong. This time, the water vapor can attack Henan, but it is basically boring in western Shandong. So there may be light rain and snow in Heze and Liaocheng around the 29th.

It can be seen that in the coming week, a province-wide rain and snow will still not land, and a small amount of rain and snow will only fall in the corner and will not change the general trend. Looking forward to a hearty snowfall coming to Shandong, the so-called auspicious snow is a good year, and sufficient rain and snow are the guarantee for next year's harvest.
