Cities with rainfall across the country these days

Zhang Mingying, a senior meteorological engineer at the Beijing Meteorological Observatory, analyzed that the abnormal climate changes this winter are mainly due to the influence of solar radiation, atmospheric circulation, geographical characteristics and human activities. The trend of global warming has not changed. The reporter learned that this winter, the precipitation in the Beijing area was significantly higher. The precipitation at the observatory was 14.7 mm, 40% more than normal (10.4 mm). The total number of snowfall days in winter was 14, which was 14.7 mm. Year-round (9.6 days) is obviously more. Meteorological experts said that excessive snowfall plays a role in keeping winter wheat and pasture warm and increasing moisture; it suppresses sand and dust, purifies the air, reduces pollution, and at the same time suppresses viruses and bacteria in the air, which is beneficial to people's health. But at the same time, periodic low temperatures have a greater impact on urban heating, and excessive snowfall has also tested urban traffic conditions. Regarding this phenomenon, Zhai Panmao, deputy director of the Department of Prediction and Disaster Mitigation of the China Meteorological Administration, said that although the temperature this winter is slightly lower than the average annual average, the trend of global warming has not changed. There will be fewer sand and dust days this spring. According to the climate trend prediction of sand and dust weather in the spring of 2005 by the China Meteorological Administration, in the spring of 2005, the cold air activity affecting my country will be weaker than the same period of normal years. The overall trend of the number of sand and dust weather days in northern China is close to that of the same period of normal years or The number of sand and dust weather days in the eastern part of North China and Northwest China is close to the same period of the year or less. In addition, the frequency of sand and dust storms in northern China is close to the same period of the year or less than the same period of the year. It is the same as or slightly less than the same period in 2004. Li Weijing, deputy director of the National Climate Center of the China Meteorological Administration, explained: "Since most areas in northern my country have not yet thawed, and there has been no strong cold air intrusion recently, the dust weather in the spring of 2005 will be less than in previous years." Related news There will be strong winds of level 6 tomorrow. According to the latest meteorological data, Beijing will turn from sunny to cloudy today. Due to the influence of cold air, there will be northerly winds of level 4 to level 5 during the day, and there will also be strong winds of level 6 in some areas. Today, the maximum temperature during the day is 4℃ and the minimum temperature at night is minus 3℃. Due to strong winds, the meteorological department reminded people who went out to pay attention to wind and fire prevention. According to Zhai Panmao, deputy director of the Department of Prediction and Disaster Mitigation of the China Meteorological Administration, it is expected that in the next 10 days, cold air activities will be more frequent in northern my country and the temperature will rise and fall significantly. In March, there were three main cold air processes that affected our country: It is expected that there will be three main cold air processes that affected our country during the month. The time and intensity of their occurrence are roughly: the beginning of the first ten days (moderate), the end of the first ten days (moderate), and the beginning of the last ten days (moderate to moderate). weak).
