沙尘天气影响全国半数省份 覆盖面积超200万平方公里

这次大范围影响北方地区的强沙尘天气,可谓来势汹汹,大气能见度不断降低。针对沙尘来袭,4日,中央气象台两次发布沙尘暴蓝色预警。

最新的气象预报显示,4日夜间至5日,北方大部将先后出现4~6级风,阵风8~9级。

这个时段内,内蒙古中东部、华北北部、东北地区西部等地局地阵风风力可达10级,新疆南疆盆地、内蒙古、甘肃东部、宁夏、陕西中北部、山西大部、河北大部、北京、山东大部、河南、吉林西部、辽宁西部、苏皖北部、湖北西北部等地的部分地区将伴有扬沙或浮尘天气,其中内蒙古中东部部分地区有沙尘暴。

根据上述预报,沙尘天气将影响全国15个省份,按照中央电视台4日晚间《天气预报》节目的介绍,沙尘波及的面积已达到217万平方公里,这也意味着,超过五分之一国土遭遇了沙尘过程。

多地PM10“爆表” 北京局地PM10浓度破两千

受这次强沙尘天气影响,北方多地空气质量达到重污染或者严重污染程度,一些城市的PM10浓度陡增,甚至“爆表”。

据监测,3日23时,内蒙古的呼和浩特、乌兰察布,PM10的浓度达到或超过了2500微克/立方米。根据中国天气网的报道,4日早上8点,中国北方出现横跨西北到东北的沙尘区,多地局部地区最低能见度仅300米。齐齐哈尔、锡林浩特、张家口、大同、鄂尔多斯、金昌多地PM10浓度均超过1000微克/立方米。

在受此次强沙尘天气影响较重的内蒙古,内蒙古环保厅数据显示,4日内蒙古呼和浩特市、包头市、巴彦淖尔市、乌海市等地AQI(空气质量指数)均在500以上,为严重污染。

就北京来看,4日凌晨4点多,沙尘主体到达北京,4日清晨,北京多个监测站点的PM10浓度破千。根据监测,4日8时,北京城六区的PM10浓度已达到1582微克/立方米,西北部、东南部和西南部的PM10均已超过2000微克/立方米。这也是北京近两年来遭遇的最严重沙尘天气过程。

三北防护林挡不住强沙尘?专家释疑

对于此次强沙尘的起源地,据报道,中央气象台环境气象中心高级工程师张碧辉表示,前期,沙源地气温偏高、降雨偏少,为起沙提供了有利条件;同时,3日蒙古国和内蒙古大风天气,引发了大范围沙尘天气。沙尘最初从蒙古国开始,逐渐向中国传输。在传输过程中,中国的沙源地也会起沙,在高空气流引导下共同影响下游地区。

对于舆论中有关三北防护林为何挡不住强沙尘的疑问,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。

据统计,截至目前,今年北方地区已出现7次沙尘天气过程,少于近十年同期平均次数(8.4次),与去年同期持平(7次)。

今日北京阵风可达8~9级 明起沙尘或影响南方地区

沙尘天气何时散去?根据上述气象预报,今天,北方大部分地区仍将是大风和扬沙相伴,根据预报,北方大部将先后出现4~6级风,阵风8~9级。

北京市气象台4日16时35分发布大风黄色预警信号,受冷空气影响,预计5日白天北京将有5、6级偏北风,阵风可达8、9级。

就空气质量来看,根据环境保护部宣传教育司官方微博“环保部发布”的消息,未来三天(5日-7日),大气扩散条件总体有利,全国大部空气质量优良,北方部分地区以良至轻度污染为主。

受强北风影响,沙尘主要影响地区逐步南移,6日起华北地区沙尘天气将逐步结束,但受沙尘传输影响,6日-7日南方部分地区可能出现短时中至重度污染。

针对北方沙尘的传输影响,以上海为例,上海市环境监测中心、上海中心气象台4日发布气象提醒,预计5日傍晚起,上海市空气质量将受到北方沙尘污染输送影响,5日夜间至6日上午沙尘将明显影响上海,空气质量以轻度至中度污染为主,短时可达重度污染,首要污染物为PM10。(完)

据新华社报道,3日以来,我国北方地区遭遇今年以来最强沙尘天气过程。中央气象台环境气象中心高级工程师张碧辉介绍,北京市环保监测中心数据显示,4日8时,北京城六区PM10浓度为1583微克/立方米,西南部为2092微克/立方米,北京全市空气质量为最高级别“6级严重污染”,能见度约2公里。

北京市预警中心、北京市气象台4日5时30分发布“沙尘蓝色预警”信号,受上游沙尘暴和扬沙天气影响,预计4日早晨到白天,北京有浮尘或扬沙天气,能见度明显下降;4日16时35分发布“大风黄色预警”信号,受冷空气影响,预计5日白天北京市将有5、6级偏北风,阵风可达8、9级,局地伴有扬沙。

据介绍,“沙尘天气”主要分为“浮尘”“扬沙”“沙尘暴”“强沙尘暴”四类。

北京为“浮尘”或“扬沙”。“浮尘”是尘土、细沙均匀地浮游在空中的现象;“扬沙”是风将地面尘沙吹起,使空气相当混浊,水平能见度在1公里至10公里以内的现象。

北京受到上游“沙尘暴”和“扬沙”天气影响,“沙尘暴”是强风将地面大量尘沙吹起,使空气很混浊,水平能见度小于1公里的天气现象。此外,“强沙尘暴”是大风将地面尘沙吹起,使空气很混浊,水平能见度小于500米的天气现象。

北京市气象台首席预报员马小会说,本次影响我国北方地区的气旋发展强盛,沙源地风速大、容易造成沙尘天气发生,随着气旋东移发展,携带上游的沙尘影响到北京地区。

张碧辉说,在垂直方向的风场高度上,北京地区在3000米高空基本是偏南风,不受沙尘影响,但5000米左右的高空是偏西气流,因此,北京的沙尘粒子,主要是5000米高度输送过来,因为压场的变化,在北京上空有个沉降过程,导致北京地区的“浮尘”天气。

北京何时结束“下沙”?马小会说,4日傍晚,沙尘天气有所减弱,但不会结束,5日,伴随着冷空气,北京将出现6级大风,阵风可达8级,为今年入春以来最强的大风过程,伴随大风,北京本地会出现“扬沙”天气,这不同于4日外来输送导致的“浮尘”。预计5日北京的能见度在5公里左右,好于4日的2公里能见度。
