查询词典 sea wind

It becomes the research focus of navy all over the world. Owing to the anomalous distribution of sea and land、coast landform、offshore wind and shoreward wind in shore, it often causes the alongshore effect of the evaporation duct. This effect will debase the veracity of the evaporation duct diagnosis.

然而由于其形成机制复杂，且在近岸沿海地区由于海陆分布不均，以及海岸地形和海陆风等因素的作用，会造成蒸发波导的近岸效应，这种效应会影响蒸发波导高度诊断的准确率。

They were, says Mr Stephen, and the end was that the men of the island seeing no help was toward, as the ungrate women were all of one mind, made a wherry raft, loaded themselves and their bundles of chattels on shipboard, set all masts erect, manned the yards, sprang their luff, heaved to, spread three sheets in the wind, put her head between wind and water, weighed anchor, ported her helm, ran up the jolly Roger, gave three times three, let the bullgine run, pushed off in their bumboat and put to sea to recover the main of America.

此语不差"，斯蒂芬先生曰，"其结果，本岛男子发现负情女子异口同声，无可救药。遂建造舟筏，携家财登船，桅杆尽皆竖起，举行登舷礼，转船首向风，顶风停泊，扬起三面帆，在风与水之间挺起船首，起锚，转舵向左，海盗旗迎风飘扬，三呼万岁，每次三遍，开动舱底污水泵，离开兜售杂物之小舟，驶至海面上，航往美洲大陆。""

The conclusion of this article contains:(1) The climatology symmetric index and antisymmetric index which represent the uniform system of ocean and atmosphere is defined according to the unique kinetic character of the large-scale fluid. The symmetric mode, a state mode, and antisymmetric mode, a propagate westward mode, of ocean and atmosphere are distinguished clearly from each other. Also, the primary part which determines the symmetric mode emerges from non-divergenct wind and the dominant part which contributes to the antisymmetric mode mostly is irrotational wind. The article also compares the disparity of the climatology distribution of SST and sea surface wind field between 1948-1975 and 1976-2005. The SST of both the tropical Indian Ocean and the tropical Pacific after 80's is warm than before 80's .

Low cloud and thunderstorm weather phenomena obvously increase, and the land and sea breeze and terrain obviously affect the precipitation distribution.

The relationships between wind field at low level and convection activities over the South China Sea are investigated based on pentad wind and OLR data from NCEP. The onset time and intensity of SCS summer monsoon are determined by area-averaged zonal wind component over central and south SCS. So we possess long-term time sequence of SCS summer monsoon activities for the period of 1949～1998. Interannual and interdecadal variations are examined by using this time series.

Therelationship between the turbulent kinetic energy and its dissipation rate,whichis widely used to parameterize the dissipation rate in turbulence closure models,is found to hold well for both reversing and rotating flows,but with differentcoefficients.Microstructure profiling measurements at two comparative stations (a deepercentral basin and a local shelf break) in the stratified Yellow Sea are analyzed,with emphasis on tidal and internal-wave induced turbulence near the bottomand in the pyenocline.The water column has a distinct three-layer thermohaline structure,consisting of weakly stratified surface and bottom boundary layers anda narrow sharp pycnocline.Turbulence in the surface layer is controlled by thediurnal cycle of buoyancy flux and wind forcing at the sea surface.while thebottom stress induced by barotropic tidal eurrents dominates turbulence in thebottom boundary layer.The maximum level at which the tidally enhanced mixingcan affect generally depends on the magnitude of the tidal current,and it canbe up to 10-15 m in the Yellow Sea.This suggests that,in the deeper regionsof the shelf seas,turbulent dissipation and mixing are very weak at the levelsbetween the near-bottom tidally enhanced layer and the pycnocline.Therefore,these levels provide a significant bottle neck for the vertical exchanges.In theshallow regions,however,the tidally-induced turbulence can occupy the wholewater colum below the pycnocline.A quarter-diurnal periodicities of the turbulentdissipation rate and eddy diffusivity are found at different heights with evidenttime lag.In the relatively flat central basin,the pycnocline is essentially non-turbulent and internal-wave activity is very weak.Therefore,vertical fluxes acrossthe pycnocline decreased to molecular levels.In contrast,internal waves of variousperiods can be always found near the local shelf break.

对强层化季节黄海两对比性站位(分别位于中央海盆区与局地陆坡区)处层化、内波以及湍流混合特征的研究结果表明：1、强层化季节的陆架海水体一般呈现显著的三层热盐结构，在水体近乎混合均匀的上混合层与潮流底边界层之间为强跃层；2、近表层水体的湍流混合强度主要由海表浮力通量的日变化与海表风强迫控制，而在潮流底边界层内，潮混合是水体热量、物质、动量与能量垂直交换的主要机制；3、潮混合影响的深度由潮流大小决定，在黄海，一般可达10-15 m，因此，在水深较深的区域，在跃层与潮混合所至深度范围的上界之间存在湍流混合非常弱的区域，这显著抑制水体内物质的垂直通量，为物质垂直交换的瓶颈，而在水深较浅的区域，潮混合影响范围可至跃层底部，因此物质在跃层以下整个水体中混合非常均匀，当跃层内间歇性强混合发生时，可以产生显著的跨跃层物质输运；4、近底潮致强湍流耗散缓慢地向上传播，底上不同深度处垂直湍扩散系数也具有显著的位相差异，且二者均随时间呈现四分之一周日周期的变化；5、在地形较为平坦的中央海盆区，内波活动非常微弱，因此跃层内湍流混合非常弱，垂直扩散系数为分子扩散水平，跨跃层物质通量受到显著抑制，而在地形变化较为显著的局地陆坡区，内波活动非常活跃，除内潮的影响外，高频内波与内孤立波的影响也很显著，因此跃层内存在很强的间歇性强混合，内孤立波存在的区域，水体湍流混合显著增强。

The glacier grows against wind. The larger the glacier grows on slope facing wind, the less the moisture air is advected to another side. The glaciers are hard to grow on another side. Thus, the snow line on the slopes facing wind is lower than on the opposite side.For the ice sheets at LGM, the climate drivers are the surface air temperature, relative sea level change and ELA at LGM. Two ELA were reconstructed. One is the altitudes of ancient cirques, and another is the height difference at 0oC level between July and May.

构建了2种ELA，一种为古冰斗、冰碛陇的高度，另一种为由7月、5月0oC层的高度差得到的ELA，分别与复原的该时期的年平均空气温度和该时期的海平面高度，构成2种外部强迫方案，对LGM时期青藏高原冰川的覆盖程度进行了模拟，对有无统一大冰盖重新进行了评估。2种模拟结果发现，尽管高原的东南部和西北部冰川分布较集中，但仍有独立的冰川中心存在，并未形成统一大冰盖。

ABSTRACT Rough sea surfaces are formed with the interaction, which is nonlinear, of seasurface wind and gravity and surface-tension of sea water. Also nonlinear is the interaction of sea surfaces with electromagnetic waves. So nonlinear theory and method should be employed in the study of EM scattering from rough sea surfaces.

粗糙海面是在海面风、海水的重力和海水表面的张力的相互作用下形成的，这种相互作用是非线性的；电磁波照射到海面后，电磁波与海面的相互作用也是非线性的；因此采用非线性的理论和方法研究电磁波与海面的相互作用更能反映其物理本质。
