2004), A Modeling Study of the Export Pathways of Pollution from Europe
Abstract. We present a study of the seasonal and interannual variations of the export pathways of pollution from Europe for eleven years, 1987-1997, using the GEOS-CHEM model of 3-d trace gas/aerosol chemistry and transport. The dominant export pathways in winter are advection to i. the middle and h...

We present a study of the seasonal and interannual variations of the export pathways of pollution from Europe for eleven years, 1987-1997, using the GEOS-CHEM model of 3-d trace gas/aerosol chemistry and transport. The dominant export pathways in winter are advection to i. the middle and high latitudes of the North Atlantic Ocean, including the European Arctic; ii. Russia and the Russian Arctic; and iii. the middle and low latitudes of the North Atlantic Ocean from western Europe and from northern Africa via the Mediterranean Basin. In summer, export occurs by both advection and convection. Transport by advection occurs predominantly to Russia and the Mediterranean Basin/northern Africa. There are two major regions of convection in summer that loft European pollution into the free troposphere, one centered over Germany and the other over the Ural Mountains in Russia. Another region of lofting, not associated with moist convection, occurs in northwestern Africa by the quasi-permanent Western Saharan Low. Summertime ozone in our model is enhanced by European pollution (~5 ppbv on average) in the middle troposphere near these three regions of lofting. In addition, European pollution causes summertime, surface ozone levels in northern Africa and the Near East, regions with a total population of about 200 million people, to exceed regularly the European Council’s human Text Arctic North Atlantic ural mountains Unknown Arctic |
