The notice stated that according to the recent weather forecast, the temperature will still fluctuate greatly after March 15. In order to ensure the heating needs of the general public, the centralized heating time for the 2020~2021 heating season in Jinan’s central urban area has been initially determined to be extended to March 23. 0 o'clock, the specific heating stop time will be determined based on temperature changes. In addition, no additional heating fees will be charged to residential heat users during the extended heating period. In addition to Jinan, heating hours have been extended in many places in Shandong. Weifang, Heze, the urban areas of Yantai, Zhaoyuan, Qixia, Penglai, and Mengyin County, Linshu County, Lanling County, and Fei County in Linyi have all officially announced The notice to extend heating makes the general public feel very heart-warming. But why did the Shandong region suffer from cold springs several times in succession after this winter? The temperature did not recover quickly, but there were multiple large-scale cooling phenomena. In fact, spring is the transition season from winter to summer, and it is inevitable that there will be sudden cold and warm periods, because our country's temperature returns relatively quickly at this time, but strong cold air will affect our country in areas such as Siberia, and cold and warm air often invade alternately. , causing frequent high and low air pressure activities, causing the weather to be hot and cold, and the temperature difference between day and night to be large. This confrontation between cold and hot will cause the temperature to rise and fall sharply, which is what people call "late spring cold". According to the Comprehensive Meteorological Observation Product System of the Meteorological Observation Center of the China Meteorological Administration, affected by the return of sand and dust, PM10 concentrations have increased in many places in the north, causing severe pollution. With the arrival of cold air and rainfall in the north, sand and dust gradually settle, and the air quality Things got better, and the PM10 particulate matter concentration dropped to about 100. However, with the arrival of the all-powerful cold air that is about to debut, it may once again bring terrible weather of strong winds, cooling, rain, snow, and dust, which will cause people to suffer a series of physiological abnormalities and various diseases. Therefore, citizens and friends are reminded to pay close attention to weather and meteorological changes, maintain good living habits, and protect their health.
