Universal Earth System mode ( cesm ) is the newly launched Earth system coupling mode of the National Center for Atmospheric Research , on Solutionno climate ( Earth ) The new challenges and issues involved in system modeling are of great help . first describes cesm mode knot Framework and important updates for the latest version ; and then combine specific instances of application and experience , focuses on how to make the high performance meter on-machine porting mode and reasonable CPU configuration , and compare the pros and cons of different configurations , To determine the mode best negative load balancing and optimal efficiency , The has great help with the use of schema new users ; The finally sets a series of stability tests on the pattern and validation , results show better stability for schemas , can be numerically simulated and scientific research . Summary of the Earth System coupling mode development , and gives some suggestions for the problems that exist in pattern development .

determine the local sea - The characteristics of the gas interaction to the sea - What type of is applied in the gas-coupled mode Forces Impersonation has important guidance action . This article is based on the correlation between sea surface heat flux anomaly and sea surface temperature anomaly and sea surface temperature variability , To the global ocean season inner scale sea - A comprehensive analysis of the characteristics of gas interaction . results show :(1) South ,Northern Hemisphere subtropical region sea - gas interaction The characteristics of the are mainly manifested by the atmospheric forcing of the Ocean , and in summer ( Northern Hemisphere : 6- 8 Month , The Southern hemisphere is - The following year 2 Month ) To Force with the widest range , Winter forced range minimum ;(2) equator , East Pacific and Equatorial Atlantic region Sea - gas Interaction special Levy for the entire year the ocean is forced on the atmosphere , Indian Ocean Somalia Coast , Arabian Sea and Bengal, B. Of area only 6- 8 Monthly Performance the phenomenon of forcing the atmosphere out of the ocean , and Bengal,B. Of 9 One one Month performance for atmospheric forcing Ocean ; (3)\°n(S ) above high latitudes The anomaly and variability of the regional sea surface temperature cannot be explained by the exchange of local geothermal fluxes. , This is because the sea surface temperature changes in the area are mainly from the advection and other ocean internal power process decisions , therefore sea - The interaction between the gas and the seasonal scale is not obvious . in certain seaareas , season internal scale sea - The relationship between gas interaction and the time scale above the season may be significantly different from .

The nutrients in atmospheric wet deposition to Zhanjiang Bay and their on the impacts marine E studied based on the rainwater investigation from May 2015 to April 2016. The results showed the rainfall during the year of investigation was significantly higher the than the average annual Rai Nfall due to the influence of El Nino. In rainwater, NOand SiO 3 2 concentrations were relatively high in summer and autumn, while NO B20>3 and PO4concentrations were Relatively high in spring and winter. The deposition fluxes of these nutrients were all highest in autumn, with a high average contribution (larger than 50%) to The wet deposition fluxes in a whole year. These seasonal variations were affected by rainfall, different sources to air masses, local human activities. A Super typhoon passing by in autumn, which brought heavy rains, contributed more to the highest deposition fluxes of Nutr Ients in autumn. The wet deposition could bring 2.04, 292.4, 8.13 and 45.8t/a of NO2-<b113 >-N, NO3-N, PO43- - p and SiO32--si into the Zhanjiang Bay. Their deposition in autumn might cause phytoplankton to increase in seawater in short period Phenomenon might be absent.

I During th Chinese National Antarctic Expedition ( ( chianre), individual particle samples were collected from South-to-Antarctic during L 2013. A transmission electron microscopy with energy-dispersive X-ay spectrometry (tem-eds) is employed to analyze the Morpholo GY, mixing state, composition, and relative abundances of individual aerosol. Atmospheric particles were classified into four types:sea salt, mineral, s ' ich and C-ich. Sea salt Aerosols (SSA) were dominant in marine particles from South to Antarctic, and they were further into three Sub-types:fresh SSA, partially aged SSA, and fully SSA. Partially and fully aged SSA accounted for 86% The total SSA number. Interestingly, surface of partially aged SSA and fully aged SSAcontained abundant rod-iike Na2</b20 >S 0 4. Mineral dust particles increased in the coastal areas, which were by influenced air. In addition, we found this s-ich particles were abundant at two sampling sites (the Middle Eastern of Indian Ocean and Ant Arctic inland). The back trajectories of air masses indicated that this s-ich particles were mainly formed via the oxidation of dimethyl Sulfide (DMS) emitted from the marine phytoplanktons. Our study suggests this SSA aging process in the South hemisphere atmosphere was controlled by the DMS which is differ ENT from the SSA aging under the influence of anthropogenic pollutants in the North hemisphere.
