目前国内的建筑美术教育,可以归纳为“传统技法训练”“结构素描训练”以及更符合当下趋势的“视知觉训练”三大体系。通过分析它们的发源和特点,对比不同学者的教学总结,可以归纳出现今国内建筑美术教育概况及其革新方向。同时,在深入分析“视知觉训练”体系之具体教学构架、特性及不足的基础上,针对地方院校建筑美术教育现状,从“在地性”“课程联动”“个人情感”等方面入手能够提出某种批判视角下的“视知觉训练”新构想,并据此进行相应的教改实验。

采用中尺度天气预报模式WRF(Weather Research Forecast)对广东省阳江地区2019年5月26日00时—28日00时暴雨事件进行数值模拟,并通过一系列的地形敏感试验,讨论地形对暴雨发生和发展的影响。结果表明:地形对暴雨的影响显著,地形的高度影响暴雨的强度和位置;与未作任何改变的控制试验相比,地形降低试验和细网格地形高度取平均试验无山脉的阻挡,阳江地区无爬流和绕流运动及相对涡度减小,南风将低层水汽和能量带到更北的位置,暴雨中心随之北抬;增高地形试验,由于山脉阻挡,更多水汽和能量堆积,以及地形的阻挡产生绕流和爬流运动,绕流有利于局地涡旋生成,爬流运动会增加垂直运动速度,正涡度中心增强,低层的水汽辐合上升凝结,造成更大暴雨。

Variations in Dissolved Methane in the yellow Sea During the Spring Algal Blooms of 2009

引用

Journal of Ocean University of China 2019年第4期18卷 896-912页

作者： ye Wangwang ZHANG guiling LI Peipei ZHOU Feng LIU Chenggang Key Laboratory of Marine Chemistry Theory and Technology Ministry of Education Ocean University of China Qingdao 266100 China Laboratory for Marine Ecology and Environmental Science Qingdao National Laboratory for Marine Science and Technology Qingdao 266071 China State Key Laboratory of Satellite Ocean Environment Dynamics Second Institute of Oceanography Ministry of Natural Resources Hangzhou 310012 China

Methane (CH4) is an important greenhouse gas and oceans are net sources of atmospheric CH4. The effects of environ- mental factors on the CH4 variation during different phases of the spring algal blooms were examined during two cruises conducted in the yellow Sea (YS) from February to April of 2009. During the pre-bloom period from February to March, low CH4 saturation (< 134%) was observed in the surface water, except at two nearshore stations where the CH4 levels were above 140% in March due to mixing with the coastal water. During the bloom period, CH4 increased obviously at two bloom-tracking stations, especially at the surface with mean saturations of 140% and 170%. The increase in CH4 concentration/saturation is thought to be the result of in situ CH4 production. The particulate organic carbon (POC) and chlorophyll a contents were believed to be important factors that influ- enced the CH4 production. In addition, the presence of different dominant phytoplankton species and the grazing pressure may have stimulated the CH4 production by supplying potential methanogenic substrates (such as dimethylsulphoniopropionate (DMSP)). Both the incubation data and the in situ estimations further evidenced the significant influence of the spring blooms on the CH4 production. The calculated sea-to-air CH4 fluxes during the bloom period were not significantly higher than those during the pre-bloom period despite the bloom-increased CH4 saturation. This is due to the variation in physical forcing (such as wind speed), which is the main driver for determining the CH4 flux. Finally, we estimated the annual CH4 flux in the YS as 9.0 μmol m 2 d 1;the findings suggest that the YS is a natural source of atmospheric CH4.

使用ERA-Interim和ERA5两套再分析资料分别驱动东亚区域再分析系统(East Asia Reanalysis System,EARS),并输出2015年一年期试验再分析资料,通过评估其中3次代表性的华南登陆台风降水过程,对比不同驱动场对该系统的影响,研究发现以ERA5驱动的EARS输出结果较ERA-Interim驱动的结果更准确,尤其在丘陵和山地等复杂地形下的降水模拟改进明显。进一步用ERA5驱动的EARS输出结果与欧洲中期天气预报中心(European Centre for Medium-Range Weather Forecasts,ECMWF)新一代陆面再分析资料ERA5-Land对比分析,发现ERA5-Land对于台风大尺度降水的把握更好,而EARS对中小尺度降水过程的再现更完整,特别是对沿海降水的模拟更准确。相较于ERA5-Land,EARS目前同化的观测资料有限,对物理过程参数化方案的选择仍欠准确,后续需要有针对性地改进。
