Abstract
The effect on climate due to seasonal variation of vegetation and roughness length was simulated in Part Ⅰ of this essay.In Part Ⅱ,the individual effect of albedo and the joint effect of all those factors (vegetation,roughness length and albedo) were calculated by numerical sensitivity experiments.The results showed that: (1) There is no significant effect on precipitation if the albedo of 4 seasons is used to replace the CRCM's climate average data,but the effect on land surface temperature can be seen clearly.And the effect also can be seen in adjacent regions.(2)If all these three factors are used to replace the CRCM's climate average data at the same time,the effect on precipitation is significant,the most variation value is 300mm.And the effect on temperature is similar to what we can see if only one of these factors in CRCM is replaced by monthly or seasonal data.(3)Seasonal variation of land surface parameters has important effect not only on regional climate,but also on global environment.
