  climate feedback
     There exist varieties of feedback mechanisms in climate system, and the different description of these climate feedback mechanisms within climate models is one of the major causes for the different responses of these models to the same direct radiative forcing (e.g., doubling CO2).
     气候系统中存在着各种各样的气候反馈机制,而气候模式对这些反馈机制描述的差异,正是造成不同模式对同一直接辐射强迫(如二氧化碳加倍)的响应不同的主要原因。

     Then the role of feedback in regional climate changes and persistence is studied theoretically. Finally, the feedback relationships between soil moisture and air tern perature in land is also investigated by utilizing this model. The results obtained are important to deeply understand the cause of regional climate changes and the feedback processes between regional climate variables.

     However,RCMs still face many challenging issues due to the complicated scale interaction over a large-range temporal and spatial scales(e.g.,from mesoscale to synoptic and planetary scale disturbances),the interaction of individual climate sub-systems(e.g.,atmosphere,biosphere,water,ice-snow,land-surface),and the lack of understanding of some complex physical processes,especially clouds and soil moisture.
     然而,区域气候是多尺度扰动(如中尺度、天气尺度、行星尺度扰动)和多圈层系统(如大气圈、生物圈、水圈、冰雪圈、陆面)相互作用的结果,同时物理过程本身具有不确定性,人们对一些复杂的物理过程,特别是土壤湿度作用以及云-气候反馈过程也缺乏深刻的理解,因此该领域的研究还面临着很多挑战。

Non-linear climate feedback analysis in an atmospheric general circulation model
      
The "constant" of proportionality is a measure of the overall strength of climate feedback processes and hence of global climate sensitivity.
      
The effective climate feedback/sensitivity, including its components, is a robust first order feature of the Canadian Centre for Climate Modelling and Analysis (CCCma) coupled global climate model (GCM) and presumably of the climate system.
      
The importance of processes which determine cloud properties and distribution is again manifest both in determining first order climate feedback/sensitivity and also in determining its second order variation with climate state.

Variations of the global mean and zonal mean net radiation in various surface conditions are analysed quantitatively with a changing cloud cover. The sensitivity of net radiation to the cloud cover and the variation of this sensitivity with the changes of other climatic variables are discussed. In addition, the feed-back of cloud cover in global climate system and its variation with other climatic variables are also dealt with qualitatively. It is found that net radiation is sensitive to cloud cover and only...

Variations of the global mean and zonal mean net radiation in various surface conditions are analysed quantitatively with a changing cloud cover. The sensitivity of net radiation to the cloud cover and the variation of this sensitivity with the changes of other climatic variables are discussed. In addition, the feed-back of cloud cover in global climate system and its variation with other climatic variables are also dealt with qualitatively. It is found that net radiation is sensitive to cloud cover and only when climatic variab!es are near their critical values, can the variation of cloud cover be omitted in climatic medeling. Because of the feed-back of cloud cover, the stability of a climatic system may change substantially when climatic variable are changing.

本文对全球平均、各纬带平均和几种特殊下垫面条件下大气顶和地表面的净辐射随云量变化的情况进行定量分析,并讨论了净辐射对云量变化的敏感性随各参数改变的情况。另外还定性地讨论了云在全球气候中的反馈作用以及这种反馈作用随各参数变化的特点。指出:一般条件下,净辐射对于云量变化是敏感的,只有当气候参数变化到临界值附近时,对气候的模拟可以不考虑云量的变化。从云量对气候的反馈来看,在气候参数发生变化时,气候系统的稳定性会发生本质的改变。

Ozone is one of the most important trace gases in the atmosphere. The greenhouse effect of the stratospheric ozone on the lower atmosphere and the'ground surface, and its feedback effect on the global climate are analysed in this paper. The cloud radiative forcing and its importance for the greenhouse effect are pointed out. The remarkable phenomenon of the Antarctic Ozone Hole is further discussed.

Synthesizing the available data at home and abroad, the authors concluded that the global climate change controlls the desertification and de-desertification by its effect on the variation in dry-wet climate over sand area; on the other hand, the desertification and de-desertification have a feedback effect on global climate change in the way of its impact on the radiation equilibrium, condensation nucleus, moisture and convection. If the global climate became warming due to the man-made CO_2 and other greenhouse...

Synthesizing the available data at home and abroad, the authors concluded that the global climate change controlls the desertification and de-desertification by its effect on the variation in dry-wet climate over sand area; on the other hand, the desertification and de-desertification have a feedback effect on global climate change in the way of its impact on the radiation equilibrium, condensation nucleus, moisture and convection. If the global climate became warming due to the man-made CO_2 and other greenhouse effect gases, the developing tendencies of desertification in northern China sand area would be that when the precipitation in the eastern China sand area increased, the desertification process would be retarded, even reversed; and the precipitation in western China decreased, the desertification would be accelerated.
