This paper, the progress in scientific investigations and research regarding the atmosphere in the polar regions over the last 30 years by Chinese scientists is summarized. Primary understanding of the relationship between the polar regions and global change, especially, the variations in time and space in the Antarctic and Arctic regions with respect to climate change is indicated. Operational weather forecasts for investigation of the polar regions have also been established. Moreover, changes in sea ice and their impact on the atmosphere of polar regions have been diagnosed and simulated. Parameterization of the atmospheric boundary layer of different underlying layers and changes in the atmospheric ozone in the polar region has also been experimented. Overall, there has been great progress in studies of the possible impact of changes in the atmospheric environment of polar regions on circulation in East Asia and the climate of China.展开更多

In this case the conventional policy of “Sustainable Development” is not sufficient to avert the impact of diminution of precipitation on Israel’s water supply. Instead, a policy of “Progressive Development” is proposed, which aims to exploit, stage by stage, first the water resources most available and at lowest cost until they are ex-hausted. Once this stage is under execution, progressive steps are taken to develop more costly resources by advanced methods of exploitation. A case study of such a development plan is the controlled deterioration of the water quality of the coastal plain aquifer of Israel.展开更多
