The forecast shows that on the 27th, the southeastern part of Beijing-Tianjin-Hebei and surrounding areas will be dominated by southerly winds, and the northwest wind will gradually strengthen in the north. Affected by the sand and dust weather process in the upstream areas, severe and above pollution may occur in central Inner Mongolia; in the central and northern parts of Beijing-Tianjin-Hebei and western Shandong are dominated by light to moderate pollution, while other areas are dominated by good to mild pollution, and the primary pollutant is mainly inhalable particulate matter (PM10).
