Based on analyzing the challenges faced by Hubei meteorological science popularization work,the suggestions of Hubei meteorological science popularization work during the " 13 th five-year" period are proposed from four aspects: further optimize operation mechanism of meteorological science popularization work,and improve work efficiency; combine full-time and part-time teams,and promote the fighting capacity of the science popularization team; adapt to the demand of multimedia publicity,and expand the connotation of popular science creation; build brand,and create a stereoscopic science popularization network.展开更多

Firstly,launching periodical meteorological science popularization into campus,village and community,and holding meteorological science forum; secondly,cooperating with municipal science association and Science and Technology Bureau,and jointly issuing the related documents of carrying out the propaganda of meteorological science popularization;thirdly,co-constructing campus weather station and meteorological science popularization demonstration community; fourthly,setting up special meteorological science lecture and report meeting; fifthly,integrating meteorological science with studies of Chinese ancient civilization based on innovation. In the form of recreation and loved by the masses,the propaganda of meteorological popular science knowledge is done well,and people recognizing,understanding,grasping and applying meteorological science is improved,thereby reaching the target of decreasing the damages of meteorological disaster to social economy and human life and property.展开更多

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
