Abstract

Simulation is the imitation of the operation of a real-world process or system which is a common method for scientific analysis. A model is required here to represent the key characteristics, behaviors and functions of the selected physical or abstract system or process. The global 3-D atmospheric model (GEOS-Chem) we use in this paper can show the mercury concentrations for elemental mercury (Hg(0)), divalent mercury (Hg(II)) and primary particulate mercury (Hg(P)). We do the simulation of mercury in the atmosphere for two 3-year periods (1999-2001 and 2049-2051), with the first 3 years (1999-2001) used for getting the 3-year average value of Hg(0), Hg(II) and Hg(P), respectively in 2000 and the last 3 years (2049-2051) used for getting the 3-year average value of Hg(0), Hg(II) and Hg(P), respectively in 2050. From the model results, we can see that the climate change from 2000 to 2050 would decrease Hg(0) surface concentration in most of the world, only except in couple very small parts, for example north-eastern of China, south-eastern of South Africa and central part of Europe. The climate change from 2000 to 2050 would increase Hg(II) surface concentration in most of mid-latitude continental parts of the world, such as the whole Africa continent and the major part of south Asia. At the same time, decrease Hg(II) surface concentration in most of high-latitude part of the world.
