平流层臭氧对地表有机氯排放的多耦合响应
Stratospheric Ozone in Response to Increased Surface CFCs Emissions
摘要
Abstract
To evaluate the stratospheric process in the response to the increased surface CFCs emissions, some simulations were carried out by the NCAR interactive chemical, dynamical and radioactive two-di-mensional (SOCRATES) model. The investigation shows that when the surface CFCs emissions is re-duced by 30%, which leads to changes of concentrations of various active chemical components in the mid-upper stratosphere, through transportation, diffusion and a series of chemical reactions;after the e-quilibrium of the various components,the relative change rate of active components In the layer from 40 km to 48 km is-20% for CIO_x ,2% for HO_x ,2% for NO_x and 5% for O_3 ,respectively. Those chan-ges result in the increase in radiation heating rate in the mid-upper stratosphere ,thus the cooling trend of the stratosphere is reduced by 0. 6 K.关键词
