Lecture 9 : pollutant transport by the wind. Mechanism for the transportation of pollutant in the arctic- wania and macky(1993) Arctic haze: history of arctic haze, first noted in the 1950s by aircraft pilots, seasonal variation-peaking in spring. In spring, march, april and may peak of pollutants. For sulfate aerosol, major constituent of arctic haze. Arctic ocean and surrounding water sinks of sulfate: pooling appears to occur, sinks are likely the arctic ocean and surrounding waters. Arctic haze: 1972- glen shaw, suggested long range transport as likely mechanism for source of arctic haze, global circulation carries in pollutants from industrialized pars of the globe, wind is carrying pollutants through global circulation near arctic. Arctic haze: why do they pool in the arctic, when you have unstable surface and stable on top then it is inversion, stable atmosphere; temperature inversion, little precipitation (no washout)
