In this paper,decadal variability of the Pacific-South America (PSA) Mode is examined from year1871 to 2008 based on the newly developed ocean and atmosphere reanalysis products.The PSAmode,mirroring the Pacific-North America (PNA) Mode in the Northern Hemisphere,emerges as thesecond EOF mode of 500mb geopotential height anomalies.

本文利用珠江口2014 年2 月和2014 年5 月的高光谱遥感反射率和实测悬浮泥沙质量浓度数据进行了两波段悬浮泥沙遥感反演模式的研究.通过分析和对比发现,冬季2 月悬浮泥沙质量浓度和光谱遥感反射率相关性较低(=0.422),春季5 月悬浮泥沙质量浓度和光谱遥感反射率相关性好=0.716.2 月为珠江口枯水期,径流量小,含沙量低,潮汐作用,涨潮泥沙输入量大于落潮,含量低..而5 月为珠江口春季丰水
资料显示廉州湾水下浅滩总体向湾外缓慢推进,但潮流深槽水深基本维持不变.为研究自然状态下潮流深槽维持其现有状态的动力学机制,基于ECOM (Estuarine and Coastal Ocean Model)模式建立了廉州湾数值模型.结果表明:南流江河口处存在一个逆时针环流,使得南流江的水沙主要向西输运,同时有一沿岸流自东北方向途经深槽而后转向西北流出湾外,使得淡水携带的泥沙不易在深槽附近发生堆积;
海-气温差是研究海-气界面交换特征的重要参数之一,对沿海地区海雾、海陆风乃至风应力的变化等具有重要影响.近百年来,在气候变暖的背景下,全球气温、海温逐渐升高,海-气温差也在不断地发生变化.在不同领域内,学者们针对海-气温差做出了多方面的研究.但以往的研究多着力于探讨海-气温差对某种大气或海洋过程的影响,对于确切海域内海-气温差时空分布的基础性研究较少.基于ICOADS、ERA-Interm、《南海
