Changes of temperature and bio-optical properties in the South China Sea in response to Typhoon Lingling, 2001

A large patch of enhanced chlorophyll a concentration (Chla), lower sea surface temperature (SST), and lower sea surface height (SSH) was revealed in the central South China Sea (SCS) in November 2001 after the passage of typhoon Lingling. Maximum SST reduction of 11 degrees C occurred one day after Lingling's passage on 11/11. Subsequently, against a background level of 0.08 mg/m(3), average Chla within the area of 12.60-16.49 degrees N, 112.17-117.05 degrees E increased to 0.14 mg/m(3) on 11/12 and then to 0.37 mg/m(3) on 11/14. Dissolved organic matter and detritus were differentiated from Chla using a recent bio-optical algorithm. They contributed 64% to the increase of total absorption immediately after Lingling, while most of the changes later (74%) were due to phytoplankton. The area under Lingling's impact covered ca. 3 degrees latitude and 4 degrees longitude, which is much greater than the two summer cases previously observed in the northern SCS. This event lasted for ca. 15 days, and resulted in carbon fixation in the order of 0.4 Mt. Such a drastic response was attributed to the coupling of typhoon-induced nutrient pumping with the pre-established cyclonic gyre in the central SCS driven by the prevailing northeast monsoon

高温高压准一维喷管流动的计算

本文首先给出了平衡气体的熵和音速的计算方法,并由此建立准一维定常等熵流动解析方法,应用于求解驻室条件为高温高压空气的喷管平衡流动。然后，考虑到喷管可以有很大的出口和喉道面积比,在喉道前及喉道后密度较大处,认为流动是平衡的,采用解析方法,在喉道后密度较小处,考虑非平衡效应,采用差分方法求解。气体状态方程采用了两种:混合完全气体状态方程和采用拟合维里系数的修正状态方程。并对两种状态方程得到的结果作了比较。结果表明,本文的解析计算方法快速直接,适用于准一维平衡等熵流动。两种状态方程的结果比较显示出分子间作用力,在高温高压流场中表现为斥力,使气体更快地膨胀与加速,其影响随着压强的增加而增加。当喷管有很大的出口和喉道面积比时,在喉道后密度较小处,考虑非平衡效应是必须的

Intrusion of Warm Water into the Taiwan Strait during Winter Monsoon of 1998 and its Ecological Response

就 1998年 2— 3月台湾海峡AVHRR表层水温和SeaWiFS叶绿素数据以及当年 2月 2 0日至 3月 8日在台湾海峡北部海区所实施的多学科现场调查资料进行综合分析 ,着重探讨暖水入侵的过程及其生态响应。结果表明 ,1998年冬季由澎湖水道北上进入台湾海峡的高温高盐黑潮入侵水强度大于往年 ,在 2月 8日— 3月 13日期间不断增强 ,直至侵占整个海峡东侧海域 ,迫使低温低盐且富含营养盐的闽浙沿岸水主流顺大陆沿岸南下。这一过程向海峡西侧海域输入营养盐并使之达到适宜的水温 ,极可能是西侧海域出现叶绿素高值区、呈现出与往年相反的叶绿素分布态势的主控机制。分析这一现象与 1997— 1998年的E1Nino事件可能存在着某种关联。Taiwan Strait is a shallow shelf channel linking the East China Sea (ECS) and the South China Sea (SCS). During winter monsoon, cold Min-Zhe Coastal Water (hereafter MZCW) rich of nutrients generally dominates the northern Taiwan Strait; warm oligotrophic Kuroshio water (hereafter KW) and Soiuth China Sea Water (hereafter SCSW) from SCS intrude into the southern Taiwan Strait. Nevertheless, Kuroshio intrusion into the Taiwan Strait was found to be stronger than usual during winter monsoon of 1998, as observed by a satellite instrument, AVHRR, and a CTD in situ. In situ data were obtained in the northern Taiwan Strait during a winter cruise of 1998 from February 20th to March 8th, which suggested that warm streamer as indicated by 18℃ isotherm approached as north as 26°N. A series of AVHRR SST daily images covering the whole Taiwan Strait region, which were got on Feb.8th, Feb.25th and Mar.13th, respectively, confirmed that warm water mainly intruded into the Taiwan Strait from the southernmost tip of Taiwan, heading northeastward along the Penghu Channel. There were also some evidences hinting that warm water coming from the Kuroshio mainstream off Taiwan in the Pacific ocean, intermittently influenced the northern Taiwan Strait from the northernmost tip of Taiwan. This effect seemed to be weakening while the northeastward Kuroshio intrusion was strengthening from February to March. The mainstream of Min-Zhe Coastal Water was thus forced to go southwestward along the Mainland coast into the southern Taiwan Strait. This process probably heated Min-Zhe Coastal Water and led to the injection of nutrients into the southern Taiwan Strait, enabling unusual high winter Chla along the Mainland coast, especially in the southwestern Taiwan Strait, as shown by a single SeaWiFS Chla imagery on March 27th. Observation in situ from February to March also confirmed Chla enhancement in the northwestern Taiwan Strait. Chla content reached as high as ca. 5 mg/m+3, which were 4 times greater than that was observed in 1995. It was suspected that the unusual strong Kuroshio intrusion and the corresponded Chla enhancement in the Taiwan Strait during winter 1998 were probably related to the very strong tropic E1 Nino of 1997～1998.国家自然科学基金重点项目 496362 2 0 ;; 国家自然科学基金 4990 60 0 8资

ON THE POTENTIAL RELATIONSHIP OF FISHING GROUND POSITION SHIFT WITH THE VARIABILITY OF SEA SURFACE TEMPERATURE IN THE TAIWAN STRAIT IN SUMMERS OF 1997 AND 1998

针对台湾海峡中上层鱼类中心渔场的变动问题 ,通过对1997～1998年夏汛期间AVHRR遥感表层水温 (SST)的分析 ,发现相应于北部和西南部中心渔场在1998年范围缩小、南界大幅北移0.5个纬度的现象 ,1997年渔场南界一线的SST ,在1998年升高可达1℃。推测SST的这种变化 ,是中心渔场出现明显位移的原因之一 ,并且与此期间发生的ElNino事件可能存在着某种关联。The areas of fishing grounds for the upper water species located in the northern and southwestern of the Taiwan Strait were found much smaller in summer of 1998 than in 1997. From 1997 to 1998, the southern borders of them shifted northward as far as 0.5 degree latitude. AVHRR SST in this region was observed, showing that mean SST along the southern borders of 1997 grounds increased in 1998. Mean SST could be 1 ℃ higher in 1998 than in 1997 at most. Thus warming of water was suggested to be one of the reasons resulting of the shift of fishing ground positions. The El Nino of 1997 to 1998 was suspected to be somewhat responsible for this phenomenon.厦门市科委项目3502Z2000101号 ;; 国家自然科学基金49906008号资助

Primary Validation of AVHRR/MODIS/TMI SST for Part of the Northwest Pacific

选取[10～35°N,110～165°E]的西北太平洋海域,利用2002年7月～2005年12月Argo浮标数据对AVHRR/MODIS/TMI SST的daily(升轨)数据进行验证.结果表明:AVHRR/MODIS/TMI daily SST与Argo浮标5～6 m层温度总体的均方差rms在0.6～0.9℃,平均偏差bias在-0.2～0.2℃,平均绝对偏差bias_abs在0.3～0.7℃.这与三传感器全球范围的SST反演目标相当,说明在本区域SST反演不存在显著偏差.各遥感SST与浮标温度的差异存在季节变化,夏季偏高,很可能与夏季垂直混合较弱,比对采用的实测水温与海表温度差距较大有关.在3种遥感SST中,TMISST偏离实测值的程度最高,且偏离范围较大.作者认为这与该区域黑潮经过,产生诸多涡旋和锋面,SST时空变化剧烈而TMI空间分辨率较低有关.本研究将为此西北太平洋海域的多源SST融合提供一个比较可靠的依据.We used Argo data during the period of July 2002 to December 2005 to validate the consistency of AVHRR/MODIS/TMI SST(Sea Surface Temperature) at daily scale in the region of [10~35°N,110~165°E].The statistic showed that between AVHRR/MODIS/ TMI SST and Argo temperature at 5～6 m depth,their rms ranged from 0.6～0.9℃ and the bias was-0.2～0.2℃.It was consistent with the accuracy of SST retrieval of 0.6～0.7℃ on global scale.However the differences between AVHRR/MODIS/TMI SST and Argo temperature varied in different seasons.TMI showed the most significant deviation from Argo data,which was probably resulted from its low resolution and the dynamic feature of SST in this specific region which had abundant eddies and fronts induced by the passage of Kuroshio.Further efforts for remote sensing SST merging in theis region would be possible based on the result we presented.国家自然科学基金(40376031,40331004,40521003);; 863计划(2006AA09A302);; 教育部创新群体计划;; 厦门大学新世纪人才计划联合资

Remote Sensing Study of Sea Surface Wind Field Around Taiwan Island During Typhoon Periods

利用1999~2005年QuikSCAT卫星遥感资料,对台风期间三种台风路径下台湾岛周边海域海面风场变化特征及成因进行了分析.结果表明,尽管台风强度被不同程度低估,台风中心附近风向反演受降雨影响明显,但遥感海面风场的大致形态仍较为合理.地形对风场特征的形成有着显著作用,它导致了台湾海峡内大风(>10 m/s)天气提前出现、中央山脉两侧背风槽(或诱生低压)形成、中央山脉两端下风面“角流”形成等现象.海峡内大风天气是否提前出现与台风中心的位置有关.不同台风路径下,“角流”和背风槽的位置和范围不同.The QuikSCAT remote sensing data from 1999 to 2005 were used to study the features and mechanisms of sea surface wind fields around Taiwan Island during typhoon periods.Twelve westward or northwestward typhoons were selected,and separated into three categories due to the situation of typhoon track and Taiwan Island.Three typhoons were analyzed in detail as typical cases of three categories.The result showed: The strength of typhoons were underestimated to different extent and the wind direction retrieval near the typhoon center was influenced seriously by rain,however the general pattern of remote sensing wind fields were reasonable.Terrain had prominent effects on the formation of wind field features;it caused some interesting phenomena,such as strong wind(>10 m/s) appearing earlier in Taiwan Strait,the formation of leeward trough and "corner flow" to the flanks of Center Mountain Range(CMR) and downstream of the tips of CMR respectively.Whether the strong winds appeared earlier still depended on the location of the typhoon center.Along different category of tracks,the location and scope of "corner flow" and leeward trough were different.福建省科技厅重大专项(2004NZ03);; “863”计划重大专项(2003AA604)福建示范区资
