The Thinking on Further Impelling Hubei Meteorological Science Popularization Work under New Situation

In this paper,new situation faced by meteorological science popularization work of China is analyzed. 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.

Extending Science Popularization Base Construction and Promoting Meteorological Science Popularization Ability

In recent years,Kaifeng Meteorological Bureau and Kaifeng Municipal Meteorological Society seriously think how to strengthen the construction of science popularization base,and take below measures improving the influence of ＂ national science popularization education base＂ and further increasing the propaganda of meteorological popular science knowledge. 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.

PROGRESS OF MARINE METEOROLOGICAL OBSERVATION EXPERIMENT AT MAOMING OF SOUTH CHINA

The coastal area of southern China is frequently affected by marine meteorological disasters,and is also one of the key areas that influence the short-term climate change of China.Due to a lack of observational facilities and techniques,little has been done in this area in terms of operational weather monitoring and scientific research on atmospheric and marine environment.With the support of China Meteorological Administration (CMA) and Guangdong Meteorological Bureau (GMB),the Marine Meteorological Science Experiment Base (MMSEB) at Bohe,Maoming has been jointly established by Guangzhou Institute of Tropical and Marine Meteorology (GITMM) and Maoming Meteorological Bureau (MMB) of Guangdong Province after three years of hard work.It has become an integrated coastal observation base that is equipped with a complete set of sophisticated instruments.Equipment maintenance and data quality control procedures have been implemented to ensure the long-term,steady operation of the instruments and the availability of high quality data.Preliminary observations show that the data obtained by the MMSEB reveal many interesting features in the boundary layer structure and air-sea interaction in such disastrous weather as typhoons and sea fog.The MMSEB is expected to play an important role in the scientific research of disastrous weather related to marine meteorology.

Review of China's scientific research progress in polar meteorology in the last 30 years

The Antarctic and Arctic are sensitive to global climate change; therefore, they are key regions of global climate change research. 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.

An Assessment of CAMS-CSM in Simulating Land–Atmosphere Heat and Water Exchanges

The Chinese Academy of Meteorological Sciences(CAMS)has been devoted to developing a climate system model(CSM)to meet demand for climate simulation and prediction for the East Asian region.In this study,we evaluated the performance of CAMS-CSM in regard to sensible heat flux(H),latent heat flux(LE),surface temperature,soil moisture,and snow depth,focusing on the Atmospheric Model Intercomparison Project experiment,with the aim of participating in the Coupled Model Intercomparison Project phase 6.We systematically assessed the simulation results achieved by CAMS-CSM for these variables against various reference products and ground observations,including the FLUXNET model tree ensembles H and LE data,Climate Prediction Center soil moisture data,snow depth climatology data,and Chinese ground observations of snow depth and winter surface temperature.We compared these results with data from the ECMWF Interim reanalysis(ERA-Interim)and Global Land Data Assimilation System(GLDAS).Our results indicated that CAMS-CSM simulations were better than or comparable to ERA-Interim reanalysis for snow depth and winter surface temperature at regional scales,but slightly worse when simulating total column soil moisture.The root-mean-square differences of H in CAMS-CSM were all greater than those from the ERA-Interim reanalysis,but less than or comparable to those from GLDAS.The spatial correlations for H in CAMS-CSM were the lowest in nearly all regions,except for North America.CAMS-CSM LE produced the lowest bias in Siberia,North America,and South America,but with the lowest spatial correlation coefficients.Therefore,there are still scopes for improving H and LE simulations in CAMS-CSM,particularly for LE.
