Energy distributions of the large-scale horizontal currents caused by wind in the baroclinic ocean   总被引：3，自引：0，他引：3

Wind is the main energy source for the generation of the internal waves and the ocean mixing. Wunsch[1] estimated that about 1 TW (1 TW = 1012 W) energy was transported into the ocean from the winds by us-ing the altimeter data. Watanabe et al.[2] numerically calculated that the mixing processes obtained 0.7 TW energy from the global wind, which afforded most of the energy needed by the maintenance of the Merid-ional Overturning Circulation (MOC). During the past 50 years, in the Norther…  相似文献

Diverging Narratives: Evaluating the Uses of the Ideal-Typical Sequence of Transport Network Development     

《The Journal of geography》2012,111(5):211-217

Abstract

The development of new transport systems has been an important and highly visible component of economic development and spatial reorganization in the past two centuries. The Ideal-Typical Sequence of network development has been a widely used model of transport development. This paper shows that this model has been used in several different ways, with different notions regarding the appropriate use, interpretation, and limitations of the model over time. Students must therefore think critically about ongoing changes to transport and communications systems and their impacts on economic and social conditions, as well as how these impacts are represented in models.  相似文献   

中国煤炭资源供应格局演变及流动路径分析   总被引：1，自引：0，他引：1  

高卫东  姜巍 《地域研究与开发》2012,31(2):9-14

利用1949—2008年的相关统计数据,分析中国煤炭资源供应格局和流动路径,结果表明:(1)国家政策变动对中国煤炭资源消费规模影响深刻,每一次政策变化都会造成能源消费规模的波动,近年来强烈的能源需求使得我国煤炭供应不得不面临进口的现实;(2)受能源需求和资源禀赋的双重压力,大规模、跨区域、长距离的煤炭运输成为我国能源运输体系的重要特征;(3)尽管煤炭运输方式在向铁路、水路和公路组合并用的多元化发展,但仍然不能满足旺盛的能源需求,煤炭运输瓶颈始终存在,变输煤为输电是缓解当前煤炭运输困难的一个途径。  相似文献   

沙尘暴过程中沙尘对流层-平流层输送的数值模拟初步分析     

姜学恭  陈受钧  顾润源  陈磊 《气象学报》2012,70(6):1223-1234

在初步明确东亚沙尘气溶胶对流层-平流层输送监测事实的基础上,利用观测资料、NCEP再分析资料以及基于中尺度天气模式MM5的数值模拟方法,对一次蒙古气旋沙尘暴过程中沙尘对流层-平流层输送问题进行了初步分析.结果表明:斜压不稳定是本次蒙古气旋发展的主要强迫要素,伴随气旋发展成熟,高空切断低涡的形成引导高空急流下落并诱发对流层顶折叠和高空位涡下传.对流层顶折叠区呈漏斗状,底部达500 hPa左右.高空急流产生近似垂直的下落,并在高空切断低涡的南侧和东侧达到最强.在对流层顶折叠区周边的300-500 hPa,上升气流与低涡区偏西、偏南、偏东气流叠加,或水平横穿折叠的对流层顶,或斜升并准垂直地穿过下落的对流层顶到达平流层,且随时间的推移,空气质点能够进一步抵达平流层中部(100 hPa).轨迹分析表明,沙尘天气区对流层低层的空气质点在气旋涡旋上升气流的驱动下呈气旋式盘旋上升,并在对流层高层形成分支,一支穿过对流层顶到达平流层,并在平流层向下游进行反气旋式螺旋运动,另一支则留在对流层高层并向下游进行准水平的气旋式螺旋运动.在高空位涡下传过程中,主要产生平流层到对流层的净输送;高空位涡停止下传之后则出现对流层到平流层的净输送,且强度随时间呈指数型增长.这一特征有利于形成更强的沙尘对流层平流层输送.  相似文献   

湖南6月区域持续性暴雨的强信号及预报概念模型     

张超  罗伯良  彭莉莉  谢傲  李易芝 《湖北气象》2021,40(1)

基于湖南汛期区域持续性暴雨典型环流分型,利用1961—2016年NCEP/NCAR再分析资料和异常度方法对湖南6月区域持续性暴雨环流型进行客观识别,并结合动力和水汽输送条件,确定湖南6月区域持续性暴雨强信号并客观量化表征,建立湖南6月区域持续性暴雨预报定量化概念模型。结果表明:43次历史区域持续性暴雨过程的回报准确率达到81%,2017—2018年3次区域持续暴雨过程试报准确率为2/3,说明该概念模型有一定预报能力,能为湖南暴雨预报业务服务提供技术支持。将该概念模型与各类模式预报产品相结合,还可开展区域持续性暴雨的中期和延伸期预报。  相似文献   

东亚地区夏季水汽输送特征   总被引：2，自引：0，他引：2  

张雪梅  江志红  刘晓东  兰博文 《热带气象学报》2009,25(6):733-739

利用1950—2002年NCEP/NCAR再分析逐日平均资料,计算全球格点整层水汽输送通量,分析东亚地区夏季水汽输送在推进过程中逐候的气候特征。研究发现：第25—44候是水汽输送变化最为明显的时段,也是水汽输送的集中期;东亚地区各个经度带的偏南风水汽输送在出现时间、北抬进程速度、北界位置、南撤速度等方面均表现出不同的特征;副高边缘的东南风水汽输送具有迂回西扩和快速东撤的特点,并且在强盛期能够到达青藏高原的东南部。  相似文献
