新华社北京12月12日电 题:北方多地遭遇沙尘天气 冬季发生沙尘暴正常吗? 新华社记者高敬 12日,冷空气裹挟着沙尘影响北方多地,中央气象台继续发布沙尘暴蓝色预警。气象预报显示,未来十天,冷空气活动频繁且势力较强,除青藏高原外,我国大部地区平均气温较常年同期持续明显偏低。 中央气象台高级工程师花丛在接受记者采访时介绍,这次沙尘天气过程影响范围较广、强度较强。截至12日下午,内蒙古中西部和东南部、甘肃、宁夏、陕西中北部、山西中北部、河北中北部、北京、天津、山东北部、辽宁、吉林西部、黑龙江中部以及新疆南疆盆地等地的部分地区有扬沙或浮尘天气,其中,内蒙古中西部部分地区有沙尘暴。 花丛表示,对于北京来说,这是近10年以来在12月份影响北京的最严重的一次沙尘天气过程。12日,北京地区空气质量严重污染,局地PM10浓度超过1700微克/立方米,能见度降至2公里。 在人们的印象里,春季沙尘天气多发,12月发生这样强度的沙尘暴正常吗? 花丛介绍,从2013年到现在的10年里,有8年都在秋冬季也就是在10月到12月这个阶段出现过大范围的沙尘天气。其中,2017年和2018年两年的12月份北方地区都出现过较大范围的沙尘天气过程。因此,虽然跟春季相比,秋冬季沙尘天气的发生频率会少一些,但也并不算罕见。 中央气象台预报显示,12日夜间至13日,北京、天津、河北中东部、山东、江苏北部、黑龙江南部、吉林中部、辽宁、新疆南疆盆地等地的部分地区仍有扬沙或浮尘天气。 花丛说,影响华北地区的沙尘天气预计13日上午基本结束。但是随着冷空气南下,黄淮、江淮的部分地区会受到沙尘输送的影响。 沙尘从何而来,后期是否会“卷土重来”?…
