Wuhan precipitation 15 years at least recently to increase rain conditions clazziquai

Wuhan precipitation 15 years at least recently to increase rainfall yesterday was the second day of the Mid Autumn Festival holiday. Jiangcheng Akitake, everywhere, blue sky and white clouds floating, from one side reflects the air quality in Wuhan greatly improved. Hankou Zhang embankment fitness lane over the blue sky and white clouds. Correspondent Li Changlin photo reporter correspondent Fu Ying Zhao Zhao, the Mid Autumn Festival holiday in autumn, the festival brings comfortable, blowing autumn dryness. The day before yesterday, some parts of Wuhan and floating point showers, but the rain did not really moisten Wuhan. In the past month, Wuhan has spent the most thirsty month in 15 years. In the next 35 days, it is difficult for our city to meet the thirst of precipitation, so please pay attention to the prevention of dryness. From late August to early September, Wuhan rainfall of 15 years at least if you look at the data, August precipitation in Wuhan is not small, there are about 163.8 mm, earlier than normal about 46.4 mm. However, nearly 90% of them were in early August. After entering mid August, our city encountered hot and sunny high temperature, and after the high heat wave, Wuhan is still a long time with rain, occasional drop of light rain can not moisten Wuhan. In early August -9, only 20 millimeters of rain fell in Wuhan, "since 1951, Wuhan has only 5 years of rainfall less than this year."." Meteorological science expert Xiao Yuan said, the latest trace back to 2001, in August 11th of that year, -9 10, Wuhan precipitation is only about 1 millimeters, is the same period of rainfall at least one year. In fact, Wuhan is not the most thirsty in Hubei at present. In August, the average precipitation in the province was 120 millimeters, nearly 20% less than that of the same period of the year. Except for the southwest of Hubei, the southwest of Jianghan Plain and the northeast, and the southwest of Hubei Province, the precipitation in other parts of the area was less than two to 70%. After September, more precipitation in our province is still less, the northwest of Shiyan, Xiangyang, Shennongjia and other places, now there have been moderate to severe drought. Weak cold air, water vapor is not sufficient to rain this year in Wuhan about the summer season, the typhoon force is not strong, the north and inland typhoon is less than normal, southerly position, leading to "master of building heat" of subtropical high, long time control including Wuhan, the Yangtze River area, and a strong performance in August mid Wuhan and surrounded by the heat, no rain. Wuhan volt say goodbye to the summer, cold air is not active, arrive cold air in Wuhan, power is not strong, and the water vapor condition is poor, it is difficult to form an effective precipitation, which also caused me to continue a little rain for nearly a month. In addition, after the end of super El Nino, La Nina phenomenon has emerged, and has the characteristics of precipitation in north south of La Nina in our performance. Less rain also makes our city relatively hot in the near future. In early September, the average temperature in Wuhan was about 26.5 degrees Celsius, which was about 0.8 degrees higher than that of the same period of the year. Since mid September, the average temperature of our city is hovering at 25 -27 C. The Mid Autumn Festival holiday, affected by the strongest typhoon "Meranti" peripheral flow since the beginning of this year, the city increased temperatures or decreased, but still difficult to achieve.

武汉降水量15年来最少 近期难有増雨条件   昨天是中秋小长假的第二天。江城秋高气爽,随处可见蓝天白云飘,从一个侧面反映了武汉空气质量大大提高。汉口张公堤健身车道上空的蓝天白云。通讯员李长林 摄   本报记者符樱 通讯员赵赵   中秋小长假的秋风,带来了节日的舒爽,也吹来了秋天的干燥。前天到昨晨,武汉一些地方断断续续飘了点阵雨,可这雨水没能真正滋润武汉。近一个月来,武汉度过了15年来最“渴”的一个月,未来三五天,我市也难遇能“解渴”的降水,请大家要注意防燥。   8月下旬到9月上旬   武汉降水量15年来最少   如果只看数据,8月份武汉的降水量不算少,有163.8毫米左右,比常年同期偏多约46.4毫米。不过这其中近九成下在了8月上旬。进入8月中旬后,我市遭遇晴热高温,而高温热浪结束后,武汉仍然长时间与雨水无缘,偶尔飘落的些许小雨无法滋润武汉。   8月中旬-9月上旬,武汉一共只下了20毫米的雨,“1951年以来,武汉只有5年的同期雨量比今年少。”气象科普专家肖远说,距今最近的一次要追溯到2001年,当年8月11日-9月10日,武汉降水量仅约1毫米,也是同期雨量最少的一年。   其实,眼下武汉还不是湖北最干渴的。8月份全省平均降水量120毫米,比常年同期偏少近二成,除鄂西南南部、江汉平原西南部和东北部、鄂东北西南部外,其他大部地区降水偏少二到七成。进入9月后,我省多地降水仍偏少,西北部的十堰、襄阳、神农架等地,眼下已经出现中到重度的干旱。   冷空气弱、水汽不充分   武汉难赴雨水之约   今年盛夏时节,台风势力不强,北上并深入内陆的台风较常年偏少,位置偏南,导致“造热高手”副热带高压,长时间掌控包括武汉在内的长江中下游地区,且表现强势,8月中旬被热浪包围的武汉与雨水无缘。   武汉出伏告别盛夏后,冷空气不活跃,南下抵达武汉的冷空气少,势力不强,加上水汽条件也不佳,难以形成有效的降水,这也造成近一个月来我市持续少雨。   此外,超强厄尔尼诺事件结束后,拉尼娜现象已现端倪,而拉尼娜在我国的表现有降水北多南少的特点。   少雨天气也使得我市近期比较燥热。9月上旬,武汉旬平均气温26.5℃左右,比常年同期偏高0.8℃左右。9月中旬以来,我市平均气温徘徊在25℃-27℃。   中秋小长假,受今年以来最强台风“莫兰蒂”外围气流影响,我市北风增强,气温或有所下降,不过仍难达到入秋标准。气象学上,连续5天的滑动日平均气温稳定降至22℃以下,才意味着秋天来了,武汉常年平均要等到9月下旬才入秋。   未来三五天多云为主   近期难有増雨条件   根据气象部门预计,未来三五天,我市仍是多云或晴天,暂时难有一场酣畅淋漓的降水,这也意味着武汉可能还会继续“渴”下去。   能否人工増雨来给武汉“解渴”?气象科普专家表示,人工增雨并非人工降雨,不可能凭空就让天下雨,必须等待合适的天气条件。比如,要有很厚的云,且是能下雨的积雨云,云还要有较广的范围。也就是原本就有下雨条件,通过人工增雨催化,让雨下大、下多点。目前看来,近期武汉多是多云天气,可能暂时难有合适的増雨条件。   气象科普专家还分析,人工增雨要综合考虑的因素很多,除了要看天气条件是否符合,还要考虑其他方面,比如是否因高温出现大面积干旱急需雨水等情况。   在无雨燥热的日子里,请大家注意补水防燥,可以适当多喝些白开水、蜂蜜水,还可以多吃些滋阴润燥的蔬菜水果,如银耳、莲藕、百合、梨等。相关的主题文章:
