At the end of December, the mainland is about to usher in a weather upheaval. Between the 28th and 29th, moderate rain and heavy snow will wreak havoc in many places, including northwest Heilongjiang, northeast Inner Mongolia, western and northern Sichuan, northern Xinjiang, eastern Tibet and other places will experience rain and snow.
This rain and snow not only adds a touch of mystery to the cold winter, but will also bring surprises to local areas with temperatures rebounding by up to 8°C.
Strong cold air hits and local temperatures rebound
And on the 28th, strong cold air has begun to approach. Light to moderate snow will occur in northern Xinjiang and along the Tianshan Mountains, and even moderate to heavy snow will occur in some areas.
This snowfall is a harbinger of impending cold weather and a gorgeous show of nature. The arrival of strong cold air caused the local temperature to rebound by 8°C in a short period of time, bringing a hint of warmth.
From the 30th to January 1st, 2024, strong cold air invaded rapidly
However, this is not the end of the cold air. From the 30th to around January 1, 2024, another strong cold air will quickly enter the market, and the scope of influence will expand to many places in the central and eastern regions.
The temperature dropped by about 6°C, and some areas in northeast Jiangnan, central Inner Mongolia, and most of Shanxi were hit by cold air with a temperature drop of more than 8°C. This time, the cold air is menacing, and the chill will be felt more deeply.
The vagaries of such weather make us wonder about the knowledge behind the weather. Cold air refers to a relatively cold air mass that usually accompanies changes in the weather. When cold air hits, the sky becomes clearer due to the increased density of the air, the temperature plummets, and the chance of precipitation increases comparatively. This is due to the condensation of water vapor into rain and snow due to the stability of the cold air.
The formation of cold air is mainly due to the movement of cold air from the polar regions to lower latitudes, forming a relatively stable cold air mass.
When these cold air masses move to warmer areas, they are prone to cooling, rainfall, or snowfall due to the large temperature difference. This explains why when cold air arrives, the weather becomes cold, accompanied by rain and snow.
This weather change is also closely related to the alternation of solar terms. The end of December coincides with the lunar wax moon, which is the last month of winter, marking the peak of cold weather. With the arrival of the cold wave, the transition between the solar terms also makes the weather show a changeable state. This is also what the agricultural proverb says: "The winter moon is like a plate in fifteen months", and the weather in the wax moon shows the brightness of a plate, and at the same time indicates the unpredictable weather.
In this time of changeable weather, we can see the wisdom of the agricultural proverb. This sensitivity to celestial phenomena and meteorology is not only the crystallization of the wisdom of the ancients, but also the inheritance of agricultural culture. Through observation and summary, they have formed a lot of experience on weather and climate, which provides a valuable reference for agricultural production. Like an ancient mirror, the proverb reflects the farmer's deep understanding of the laws of nature and provides a unique perspective on how the weather changes.
In the face of the coming strong cold air, we need to prepare in advance. It is an effective means to cope with cold air by strengthening the work of keeping warm, preventing the freezing hazards that may be brought about by the cold wave, reasonably arranging life and rest, and enhancing the body's immunity. At the same time, transportation and electricity also need to be handled carefully to ensure the normal progress of life.
Overall, the weather at the end of December was unusually varied. From moderate rain and snow to the arrival of strong cold air, we see the variability and complexity of the weather. The wisdom of agricultural proverbs and solar terms provides us with another perspective on understanding weather phenomena. Through continuous learning and Xi, we can better adapt to the natural environment and meet various meteorological challenges in the future.
