Document Summary
Wind week 9: pollutant transport by the wind measuring wind. Long range transport of pollutants in the arctic: arctic haze, persistent organic pollutants (pop, 1972 glen shaw. Causes for pollutants pooling in the arctic: stable atmosphere due to persistent temperature inversion (winter, spring solar radiation destroys the temperature inversion and pollutants mix vertically and dissipate. Source of the pollutants: coal plants in eurasia located further north than n america and china. Impact of arctic haze: reduced visibility in spring, snow and ice in the arctic become contaminated, this can be stopped by reducing the emissions of sulfates from coal plants. Pops still significant in the arctic since: global distillation: pops rise in the warm air and condensates in the cooler temperatures, lower temperature leads to direct deposition and absorption on matter. Remedy: many countries have ceased the production of pops, western countries have banned. 4 cups 90 deg apart the cups rotate to measure the wind speed.
