潮汐对瞬态气候响应模拟的影响研究

In this study, the impact of oceanic processes on the sensitivity of transient climate change is investigated using two sets of coupled experiments with and without tidal forcing, which are termed Exp_Tide and Exp_Control,respectively. After introducing tidal forcing, the transient climate response(TCR) decreases from 2.32 K to 1.90 K,and the surface air temperature warming at high latitudes decreases by 29%. Large ocean heat uptake efficiency and heat storage can explain the low TCR in Exp_Tide. Approximately 21% more heat is stored in the ocean in Exp_Tide(1.10×10~(24) J) than in Exp_Control(0.91×10~(24) J). Most of the large ocean warming occurs in the upper 1 000 m between 60°S and 60°N, primarily in the Atlantic and Southern Oceans. This ocean warming is closely related to the Atlantic Meridional Overturning Circulation(AMOC). The initial transport at mid-and high latitudes and the decline in the AMOC observed in Exp_Tide are both larger than those observed in Exp_Control. The spatial structures of AMOC are also different with and without tidal forcing in present experiments. The AMOC in Exp_Tide has a large northward extension. We also investigated the relationship between AMOC and TCR suggested by previous studies using the present experiments.     

Mesoscale eddies in the South China Sea and their impact on temperature profiles

Some life history statistics of the mesoscale eddies of the South China Sea (SCS) derived from altimetry data will be further discussed according their different formation periods.A total of three ATLAS (autonomous temperature line acquisition system)mooring buoys data will be analyzed to discuss eddies‘ impact on temperature profiles.They identify that the intraseasonal variation of SCS thermocline is partly controlled by mesoscale eddies.

台湾海峡海流结构及海水通量

主要根据台湾海峡的实测海流资料，以夏、冬为代表季节，分析了台湾海峡２—３个纬向断面的海流结构，计算出各断面的海水通量。结果表明：夏季，台湾海峡中、北部海域各层的海流一般偏Ｎ向流动，Ｎ向的海水净通量为３．３２×１０６ｍ３·ｓ－１；冬季，高温高盐的黑潮水和南海水由南向北经南部断面进入台湾海峡，其海水通量分别为１．６９×１０６ｍ３·ｓ－１和０．５９×１０６ｍ３·ｓ－１；而东海水由北向南通过北部断面进入台湾海峡，其海水通量为１．０２×１０６ｍ３·ｓ－１，其中，有０．４０×１０６ｍ３·ｓ－１的海水沿着福建和广东近岸流进南海，其余０．６２×１０６ｍ３·ｓ－１的海水在台湾海峡北部混合后随同黑潮水和南海水流入东海。总之，流经台湾海峡的Ｎ向海水净通量为１．７４×１０６ｍ３·ｓ－１。     

等高线自动绘制中断层处理的新方法

提出了一种断层处理新方法——分块法与断层恢复法合成算法，这种方法兼有分块法与断层恢复法的优点同时又克服了其不足，较好地解决了含逆断层时煤层底板等高线自动绘制及任意边界的构网问题，使绘出的等值线图误差较小，更加符合实际。
