沙漠变“雪海”是怎么回事 沙漠变“雪海”原因是什么

 据媒体报道,1月14日晚间到1月15日,新疆吐鲁番市鄯善县迎来2020年的第一场降雪,据当地气象局消息,本次降雪的降雪量达9.8毫米,雪深10厘米,是该县40多年来最大降雪量。而就在该县附近的库木塔格沙漠由于降雪的影响,雪花覆盖在沙漠上,沙漠变成了雪海。

According to media reports, from the evening of January 14 to January 15, Shanshan County, Turpan City, Xinjiang ushered in the first snowfall in 2020. According to the local meteorological bureau, the snowfall reached 9.8mm, with a depth of 10cm, which is the largest snowfall in the county for more than 40 years. In the Kumutag desert near the county, snow covers the desert and the desert becomes a snow sea due to the impact of snowfall.

大雪后的库木塔格沙漠,过往单调的黄沙披上银白的衣裳,雪漠无垠宛如画卷。但这场大雪对鄯善县人民群众生产生活城市运行、工农业生产、交通运输、旅游等造成一定影响。鄯善县气象局天气预报员哈里旦·喀迪尔说:“预计此次降雪过程将持续至傍晚时段,该天气过程降雪较强,对交通安全和设施农业带来不利影响。鄯善县气象局及时发布了道路结冰黄色预警信号,提醒相关部门做好应对措施。”

The kumutage desert after the heavy snow, the monotonous yellow sand in the past covered with white clothes, the snow desert is boundless like a picture. However, the heavy snow has a certain impact on people's production and life, urban operation, industrial and agricultural production, transportation, tourism, etc. in Shanshan county. Haridan Kadil, weather forecaster of Shanshan Meteorological Bureau, said: "it is expected that the snowfall will last until the evening, and the heavy snowfall will have a negative impact on traffic safety and facility agriculture. Shanshan Meteorological Bureau issued yellow warning signal of road icing in time to remind relevant departments to take countermeasures. "

强降雪天气也使供热部门启动供热应急预案。据鄯善县供热公司副经理董富强介绍,供热公司在少拉慢跑、保证安全的前提下,增派车辆备足燃料,人员24小时在岗,维修人员全部在位及时抢修,保证全县各族人民过冬温暖。

Heavy snowfall also made the heating department start the heating emergency plan. According to Dong Fuqiang, deputy manager of Shanshan County heating company, on the premise of less jogging and ensuring safety, the heating company will send more vehicles to prepare enough fuel, and the personnel will be on duty 24 hours a day, and all the maintenance personnel will be on duty in time for rush repair, so as to ensure the winter warmth of the people of all ethnic groups in the county.

鄯善县居民凯丽曼·艾合买提说:“我们打算下班后一起打雪仗、堆雪人、吃火锅,纪念一下这场特别的大雪。”市民帕日扎提·排力丁说:“我们鄯善很久没有下过这么大的雪,我刚带着孩子从库木塔格沙漠回来,白茫茫的雪,景色非常非常漂亮,瑞雪兆丰年,我希望今年是一个丰收之年。” 

"We plan to have a snowfight, make snowmen and eat hot pot after work to commemorate this special snow," said kailiman ahimati, a resident of Shanshan county "We haven't had such a big snow in Shanshan for a long time. I just came back from Kumutag desert with my children. The snow is white and the scenery is very beautiful. The snow is a good year. I hope this year will be a good harvest year," said parizati pailiding, a citizen  

从气象角度来看,降雪需要冷空气和水汽的配合,二者缺一不可,如若其中一方“配合不到位”,降雪量也就随之较少。此次降雪是东移的冷空气与充足的西南水汽完美配合的结果。

From the meteorological point of view, snowfall needs the cooperation of cold air and water vapor, both of which are indispensable. If one of them "does not cooperate in place", the snowfall will be less. The snowfall is the result of the perfect combination of the cold air moving eastward and sufficient water vapor in the southwest.
