Haze over Eastern China 華北/華東的空氣污染

Across eastern China, the increased use of coal and wood for heating in the winter often leads to widespread haze, such as that seen in this Moderate Resolution Imaging Spectroradiometer (MODIS, [1]) image from the Terra satellite [2] on February 9, 2004. The topography contributes to the effect, as this region is very bowl-like and ringed by mountainous terrain to the west, which prevents the pollution from dispersing.

在整個華東地區，因冬季取暖而燃燒的煤炭和木材越來越多，經常引起廣泛分布的霧霾，譬如這張2004年2月9日從Terra衛星拍攝的照片所示。地形也是該現象的成因之一，因為這個地區地勢較低，西面又環繞了山地，從而阻止了污染的疏散。
