1Model simulations of the annual cycle of the landfast ice thickness in the East Siberian Sea显示文摘The annual cycle of the thickness and temperature of landfast sea ice in the East Siberian Sea has been examined using a one-dimensional thermodynamic model. The model was calibrated for the year August 2012–July 2013, forced using the data of the Russian weather station Kotel'ny Island and ECMWF reanalyses. Thermal growth and decay of ice were reproduced well, and the maximum annual ice thickness and breakup day became 1.64 m and the end of July. Oceanic heat flux was 2 W.m–2 in winter and raised to 25 W.m–2 in summer, albedo was 0.3–0.8 depending on the surface type(snow/ice and wet/dry). The model outcome showed sensitivity to the albedo, air temperature and oceanic heat flux. The modelled snow cover was less than 10 cm having a small influence on the ice thickness. In situ sea ice thickness in the East Siberian Sea is rarely available in publications. This study provides a method for quantitative ice thickness estimation by modelling. The result can be used as a proxy to understand the sea ice conditions on the Eurasian Arctic coast, which is important for shipping and high-resolution Arctic climate modelling.YANG Yu Matti Leppranta LI Zhijun Bin Cheng ZHAI Mengxi Denis Demchev 2015Advances in Polar Science2015,26,2:5
2Validation of the Model Obtained Ice Drift Fields Based on Satellite Derived Data Using a Vector Correlation Indexes in an Invariant Form显示文摘文章考虑在向量代数学上用新奇方法论为数据建模的海冰的确认的结果理论底。vectorial 代数学的途径发展了并且在在为向量 valueswind 的时间系列的分析的俄国的使用,水流冰飘移等等。vectorial 代数学的途径显著地允许压缩起始的信息并且最足够地描述向量时间系列照原尺寸并且模型数据在不变的表格由一套统计特征限制了。为当模特儿的数据并且在 situ 的关联的快速的分析(或导出的卫星) 数据简化关联的一个系统不变的指示物被使用。这方法论被申请向量的确认在第一次珍视域。方法给一个机会描述向量关联的域并且检测一有在模型之间并且在 situ 的关联的不同层次的区域(或另外的引用) 向量数据。工作在框架被执行我的海洋工程(FP7 ) 。Vladimir Aleksandrovich Volkov Denis Mikhailovich Demchev Nikolay Evgenievich Ivanov 2017Journal of Shipping and Ocean Engineering2017,7,6:0
