Abstract:

The influence of the stratosphere on the troposphere is an important issue to accurately evaluate and predict tropospheric cli-mate changes． Stratospheric chemical compositions，especially the stratospheric ozone,could influence the dynamic and thermal processes by changing the radiation balance in the stratosphere as well as the troposphere． Studies on the influence of the stratospheric ozone on the tropospheric climate via the radiative and dynamic processes are reviewed in this paper． The stratospheric ozone can affect the tropospheric temperature by infrared heating，and the radiative forcing of the stratospheric ozone can be calculated using Chemistry－ Climate Model (CCM) ． However the shortages of radiation scheme in the CCM bring large uncertainties for the estimation of radiative forcing． From the perspective of dynamic processes，the variations in the stratospheric ozone can change the vertical and meridional temperature gradient and further influence the refractive index of planetary waves as well as the propagation and reflection of planetary waves in the stratosphere and even the troposphere． Thus，the climate systems in the upper troposphere and lower stratosphere are affected through wave － mean flow interactions． In addition，many previous researches have documented that ozone depletions over the Antarctic regions can influence the synoptic and climate systems during spring and winter in the middle and high latitudes in the South-ern Hemisphere through the annular modes． But the quantitative contributions and physical mechanism associated with them are worthy of investigation． It should be pointed out that the relationship between the stratospheric ozone variations and climate changes in the mid-dle and high latitudes over the Northern Hemisphere is more complicated than that over the Southern Hemisphere，which requires more researches in the future．
