In the past two days, North China, Huanghuai and other places have ushered in the first large-scale rain and snow weather process since this winter. This rain and snow has turned many places into a world covered in silver, and it has also made many people feel the warmth and romance of winter. However, this rain and snow has also had a great impact on transportation, agriculture, life and other aspects, and has also made many people worry about the next weather changes.
You may not know that this rain and snow is just an appetizer for us in winter. Starting tonight, the rain and snow in the new ** range will start again!The strongest cold air of the winter beginsWhat does this mean?How does this affect us?
To understand the causes of rain and snow, we must first know how rain and snow are formed. The formation of rain and snow is mainly due to the collision of cold and warm air currents. When cold air meets warm, moist air currents, condensation occurs, forming clouds. When the water vapor in the cloud reaches a certain saturation, it will turn into raindrops or snowflakes, which will fall to the ground and form rain and snow.
So, why has there been a wide range of rain and snow in my country recently?This is mainly due to the fact that China is under the influence of the winter monsoon, and the cold air frequently moves southward and meets the warm and humid airflow from the south, resulting in atmospheric instability and the formation of multiple low-pressure systems, which triggers the rain and snow weather process.
According to the forecast of the ** meteorological observatory, from December 13th to 15th, the central and eastern regions of China will also usher in a range of rain and snow weather processes. Among them, there is light to moderate rain or sleet in the central and southern parts of North China, Huanghuai, Jianghuai, Jianghan, Jiangnan, and the eastern part of Southwest China, and there is heavy rain or snow locally. In Northeast China, the central and eastern parts of Inner Mongolia, and the eastern part of Northwest China, there is light to moderate snow or sleet, and there is heavy snow or blizzard locally.
This round of rain and snow weather process is due to the development of a strong cold air from the Siberian high pressure center, meeting with the warm and humid airflow in the south of China, forming an eastward moving low pressure trough, which pushes eastward along the middle and lower reaches of the Yangtze River, driving the development and diffusion of rain and snow.
The most direct impact of rain and snow is cooling. Rain and snow will consume a lot of heat, causing the ground temperature to drop, and the cold air will also cause the temperature to drop further. According to the forecast of the ** Meteorological Observatory, the strongest cold air since this winter is also "gearing up", and the rain and snow weather will bring drastic cooling to most parts of our country in the next few days, and it is necessary to pay attention to precautions.
It is expected that from the 13th to the 15th, the temperature in the central and eastern parts of China will generally drop by 6 10, locally more than 12, the minimum temperature in North China, Northeast China and other places will drop to minus 10 20, locally below minus 30, and the minimum temperature in the northwest region, the Qinghai-Tibet Plateau and other places will also drop to minus 20 30. Such low temperature will have a certain impact on the health and physiological function of the human body, especially the elderly, children, patients with chronic diseases, etc., should pay attention to keeping warm to prevent the occurrence of colds, frostbite and other diseases.
Another important impact of rain and snow is traffic. Rain and snow can lead to slippery roads, poor visibility, and frozen snow, which brings great difficulties and risks to transportation. According to statistics, in the past two days, there have been large-scale delays, cancellations, and closures on highways, airports, and railway stations in many provinces across the country, affecting the travel plans of millions of people.
With the arrival of a new round of rain and snow, the traffic situation may further deteriorate, especially in some mountainous areas, bridges, tunnels and other accident-prone areas, special attention should be paid to safety, avoid speeding, overloading, fatigue driving and other behaviors, try to choose public transportation, or arrange travel time reasonably to avoid rush hours.
The impact of rain and snow is also related to agriculture. Rainy and snowy weather will bring certain advantages and disadvantages to agricultural production. On the one hand, rain and snow weather is conducive to increasing soil moisture, improving drought conditions, and laying a good foundation for next year's spring ploughing.
On the other hand, rain and snow weather will also bring certain damage to crops, especially some winter crops, such as wheat, rape, vegetables, etc., if you encounter extreme weather such as low temperature, snow, freezing, etc., there will be frost damage, lodging, pests and diseases, etc., affecting the growth and yield of crops. Therefore, the agricultural sector and farmers should pay close attention to weather changes and take protective measures in a timely manner, such as mulching, drainage, snow removal, warming, etc., to reduce the adverse effects of rain and snow on agriculture.
The impact of rain and snow weather will eventually be implemented in life. Rainy and snowy weather will bring some inconvenience and trouble to our daily life, such as the increase in demand for water, electricity, gas, heating, etc., and the pressure on the first side will also increase, and there may be a shortage of supply, resulting in water outages, power outages, gas outages, heating and other phenomena in some areas, causing trouble to the lives of residents.
In addition, rain and snow will also affect our leisure and entertainment activities, such as travel, shopping, sports, etc., making our lives monotonous and boring. Therefore, we should arrange our lives reasonably according to the changes in the weather, make emergency preparations, maintain a good attitude, and enjoy the good times in winter.
With the arrival of the strongest cold air this winter, widespread rain and snow have returned, bringing a series of impacts and challenges to our lives. In the face of the uncertainties of cooling, transportation disruption and agricultural production, we need to pay more attention to the weather dynamics and adjust our life plans reasonably to ensure a safe passage through the cold period. At the same time, bravely welcome the winter warmth brought by rain and snow, and make life more colorful through reasonable arrangements for leisure and entertainment. In this cold season, stay optimistic, face challenges together, and believe that a warm spring is coming.
