DEVELOPMENT OF THE 2-D COUPLED STRATOSPHERICTROPOSPHERIC DYNAMICAL-RADIATIVE-CHEMICAL MODEL—PART Ⅱ:THE RESULTS AND DISCUSSION OF SENSITIVITY EXPERIMENTS
By using the 2-D stratospheric-tropospheric dynamic-radiative-chemical coupled model,somesensitivity experiments have been done,which are interactions among ozone,radiation andtemperature,vapor effects,as well as effects of source and sink.The result of temperatureexperiment shows that feedback interaction among ozone,radiation and temperature,mainlyoccurs in the upper and middle stratosphere,the maximum of ozone concentration decrease is 1ppm,the maximum of temperature change is 6 K,and the maximum of total ozone change is 20DU.From the experiment of water vapor,we can see that the area of the middle and high latitudesof the Northern Hemisphere is sensitive to vapor change.When the maximum difference betweenboth surface sources is in the Antarctic,the maximum of ozone change is also there.Because thecharacter of surface varies with latitude,dry deposition is different in different latitudes.Thechange of dry deposition makes ozone in boundary layer quite obvious,especially in both poles.The maximum change of total volume ozone in experiments of vapor,source and sink is more than12 DU.
