局地PM10浓度破2000 北方遇今年来最强沙尘
稿源: 中国新闻网   2019-05-22 16:55:00报料热线:81850000

  中新网5月4日电综合消息,中国北方今日遭遇今年最强沙尘天气,目前黄沙足迹遍布包括新疆、甘肃、宁夏、陕西、内蒙古、山西、河北、北京、天津、辽宁、吉林、黑龙江在内的10余省(市、区),影响面积超过150万平方公里。据中央气象台预测,明天夜间开始,受冷空气东移和降水的共影响,沙尘天气将逐渐减弱。

  影响面积超150万平方公里明天夜间将逐渐减弱

  今天凌晨,来自内蒙古和蒙古国的沙尘天气到达北京。这不仅是北京近2年最严重的一次沙尘天气过程,也是北方今年遭遇的最强沙尘天气。

  中央气象台今日6时发布沙尘暴蓝色预警,4日8时至5日8时,新疆南疆盆地、内蒙古中西部、甘肃中西部、宁夏、陕西北部、山西中北部、河北北部、北京、吉林西部和黑龙江西南部等地的部分地区将有扬沙或浮尘天气,其中内蒙古中西部等地的部分地区将有沙尘暴,局地强沙尘暴。

  据中央气象台官方微博消息,目前黄沙的足迹已遍布包括新疆、甘肃、宁夏、陕西、内蒙古、山西、河北、北京、天津、辽宁、吉林、黑龙江在内的10余省(市、区),影响面积超过150万平方公里。

  在风云四号卫星云图上已经出现一条明显的黄沙带。此次沙尘覆盖范围广、强度惊人。内蒙古、北京、河北等地PM10持续保持在1000微克/立方米以上。北京空气质量跌至严重污染级别。

  据中央气象台预测,明天夜间开始,受冷空气东移和降水的共影响,沙尘天气将逐渐减弱。

5月4日,呼和浩特空气严重污染,市内9个监测点的空气质量指数(AQI)均为最严重的500,指数爆表。上午9时数据显示,细颗粒物PM2.5为398,首要污染物PM10为1581。 中新社记者 刘文华 摄

  沙尘是啥?

  沙尘到底是啥?“吃土”都叫沙尘暴吗?其实,按照对能见度影响的由轻到重,沙尘天气可分为浮尘、扬沙、沙尘暴、强沙尘暴和特强沙尘暴。

  据中国天气网的梳理,浮尘程度最轻,是指尘土、细沙均匀地浮游在空中,使水平能见度小于10公里的天气现象;扬沙天气时,风将地面尘沙吹起,使空气相当混浊,水平能见度在1公里至10公里以内的天气现象;当达到沙尘暴级别,大风会将地面大量沙尘吹起,使空气变得很浑浊,水平能见度小于1公里;强沙尘暴则是强风将地面沙尘吹起,空气模糊不清,浑浊不堪,水平能见度小于500米;而最恐怖的特强沙尘暴出现时,狂风将地面沙尘吹起,空气特别浑浊,水平能见度不足50米。

  据气象专家介绍,本次沙尘天气的成因有三点:近期北方地区降水偏少,气温偏高,气象条件有利于沙尘天气的生成;本次影响北方地区的气旋发展强盛,沙源地风速大,易造成沙尘天气发生。

  也有不少人表示疑问,既然有三北防护林等防沙手段,为何还会有沙尘天气。中央气象台环境气象中心高级工程师张碧辉表示,三北防护林等措施主要是改善局地气候、起到防风固沙的作用,但是对于远距离、高空传输的沙尘作用有限。就以本次影响北京的沙尘来说,是通过高空5000米的偏西气流传输而来,防护林的高度难以阻挡沙尘。

5月4日,天津遭遇浮尘天气,空气质量急剧下降,PM10浓度暴增。天津市气象台预测,5日天津的沙尘天气将由浮尘加重为扬沙,到6日之后,沙尘天气可能会结束。图为天津地标建筑之一的“天塔”在沙尘中若隐若现。中新社记者张道正摄

  如何防范四招保护自己

  面对沙尘天气,该如何防范呢?中央气象台发布了防御指南:做好防风防沙准备,及时关闭门窗;注意携带口罩,纱巾等防尘用品,以免沙尘对眼睛和呼吸道造成损伤;做好精密仪器的密封工作;把围板、棚架、临时搭建物等易被风吹动的搭建物固紧,妥善安置易受沙尘暴影响的室外物品;由于能见度较低,驾驶人员应控制速度,确保安全;机场、高速公路、轮渡码头采取措施,保障交通安全。

  据新京报报道,以下4招可以保卫呼吸道:外出戴口罩,回家快洗脸;多喝水;多吃富含维生素蔬果;家中勤除尘。
