据生态环境部官方微博消息,生态环境部今日通报5月中下旬全国空气质量预报会商结果:5月中下旬,京津冀及周边区域大气扩散条件总体一般,空气质量以良至轻度污染为主。长三角区域中北部空气质量以良至轻度污染为主,局部可达中度污染。新疆南疆盆地、甘肃河西地区等可能受沙尘影响,出现中至重度污染。

中国环境监测总站联合中央气象台和北京市环境保护监测中心以及长三角、东北、华南、西南、西北区域空气质量预测预报中心开展5月中下旬全国空气质量预报会商,结果如下:

京津冀及周边区域大气扩散条件总体一般,空气质量以良至轻度污染为主。其中,16日,区域整体大气扩散条件一般,空气质量以良至轻度污染为主;山东东部、河北南部、山西北部受可能的降水影响,污染物可能得到一定程度的清除;区域中南部受持续湿度较大影响,可能出现轻至中度污染,受影响的城市包括北京、唐山、廊坊、石家庄、保定、太原等,首要污染物为PM2.5和O3。17~18日,大气扩散条件逐步改善,区域大部空气质量以良至轻度污染为主,中南部部分城市可能出现短时中度污染,首要污染物为PM2.5和O3。19~24日,大气扩散条件总体有利,区域大部空气质量以良至轻度污染为主,局地可能出现中度污染,首要污染物为O3。

其中,北京大气扩散条件总体较好,空气质量以良为主。其中,16日,大气扩散条件较一般,空气质量为轻度污染,首要污染物为PM2.5。17~21日,大气扩散条件持续较好,空气质量以良为主,首要污染物为PM2.5和O3。22日,大气扩散条件略有转差,空气质量为良至轻度污染,首要污染物为PM2.5和O3。23~25日,受较强冷空气影响,大气扩散条件较好,空气质量以良为主,首要污染物为O3。

东北区域整体大气扩散条件一般,空气质量以良至轻度污染为主,首要污染物为PM2.5和O3,局部地区可能出现中度污染。其中,16~17日,区域整体大气扩散条件较好,区域大部空气质量以优良为主,局部地区轻度污染。18~20日,区域整体大气扩散条件一般,区域大部空气质量以良至轻度污染为主。21~23日,区域整体大气扩散条件不利,区域大部空气质量以良至轻度污染为主,辽宁中西部可能出现中度污染。24~25日,大气扩散条件有利,区域大部空气质量以优良为主,局部地区轻度污染。26~28日,大气扩散条件一般,区域大部空气质量以良至轻度污染为主。29~31日,大气扩散条件好转,区域大部空气质量以优良为主,局部地区轻度污染。

长三角区域中北部空气质量以良至轻度污染为主,局部可达中度污染,首要污染物为O3,南部地区以良为主。其中,16日,中北部空气质量良至轻度污染,局部中度污染,首要污染物为O3,南部以良为主。17~18日,局部地区有降水,整体空气质量良至轻度污染,首要污染物为O3和PM2.5。19~20日,大气扩散条件好转,受降水过程影响,区域大部空气质量以良为主。21~23日,大气扩散条件略有转差,中北部空气质量以良至轻度污染为主,首要污染物为O3和PM2.5,南部以良为主。24日,大气扩散条件较差,中北部空气质量以轻度污染为主,局部可达中度污染,南部空气质量良至轻度污染,首要污染物为O3和PM2.5。25~26日,大气扩散条件一般,区域大部空气质量以良至轻度污染为主,首要污染物为O3和PM2.5。27~31日,大气条件有利于臭氧生成,区域大部空气质量以良至轻度污染为主,中部局部达中度污染,首要污染物为O3。

华南区域大气扩散条件总体有利,空气质量以优至良为主。其中,16~17日,大气扩散条件一般,区域大部空气质量以优至良为主,湖北中部和福建沿海轻度污染。18~20日,湖北和湖南可能出现大范围降雨,区域空气质量为优至良。21~24日,大气扩散和湿清除条件有利,区域空气质量为优至良。25~28日,大气扩散条件转不利,区域大部空气质量为优至良,湖北中部、广东大部和福建沿海可能出现轻度污染。29~31日,受强降水影响,大气扩散条件逐步转好,区域大部空气质量以优至良为主,首要污染物为O3或PM2.5。

西南区域大部空气质量以良为主。受四川盆地高温和少云影响,四川盆地在中旬和下旬分别有一次臭氧污染过程,云南、西藏、贵州局部可能出现轻度污染。其中,16~18日,四川盆地大部空气质量轻度污染,局部中度污染,区域其他地区空气质量以良为主,云南、西藏局部轻度污染,首要污染物为O3。19~22日,四川盆地、重庆、贵州、云南大部有区域性降水,区域空气质量优或良。23~24日,区域大部空气质量以良为主,四川盆地部分、重庆、云南局部为轻度污染,首要污染物为O3。25~26日,四川盆地、重庆、贵州、云南大部有区域性降水,区域空气质量优或良。27~31日,区域大部空气质量以良为主,四川盆地部分、重庆、云南、贵州局部为轻度污染,首要污染物为O3。

西北区域大部以良至轻度污染为主,新疆南疆盆地、甘肃河西地区等可能受沙尘影响,出现中至重度污染。其中,16~18日,区域大部地区空气质量以良至轻度污染为主,陕西关中局部地区可能出现中度污染,首要污染物为PM10和O3;南疆盆地、甘肃河西地区可能出现沙尘天气,部分时段可能达到重度污染,首要污染物为PM10。19~23日,区域大部空气质量以良为主,局地为轻度污染,首要污染物为PM10和O3;南疆盆地受沙尘影响,可能出现短时重度及以上污染,首要污染物为PM10。24~26日,区域大部地区空气质量以良至轻度污染为主,首要污染物为PM10和O3;新疆南疆地区及青海局部地区可能出现短时中度以上污染,首要污染物为PM10。27~30日,区域臭氧污染突出,大部地区空气质量以良至轻度污染为主,局部可能出现中度污染,首要污染物为PM10和O3;新疆局部受沙尘影响可能出现中度以上污染,首要污染物为PM10。
