2004, (1): 73-82.
Abstract:
The relationship between sea surface temperature anomaly (SSTA) in the domain from the northwest of thc Pacific to Chinaseas (NWP-CS) andclimate (precipitation and surface temperature) anomaly in winters over east of Chinese Mainland (ECM) are invest...

JIANG Tao, LIU Yun, WANG Wenzhi
2004, (1): 83-90.
Abstract:
Based on the output data from 1997 to 2000 obtained by the MITgcm's (general circulation model) adjoint assimilation method, volume, heat and salt transports through the Luzon Strait are calculated. The results indicate that there are obvious differe...
