| 摘 要： | 对来自于美国国家环境预报中心公布的NCEP1、NCEP2 再分析资料和来自于定点布放在黄海北部的浮标观测资料进行了比较和分析。结果是： NCEP 再分析资料中的海表气象参数（风速、湿度、气温、海表温度）是可信的。在统计意义上, NCEP2 给出的海表气象参数比NCEP1 与浮标观测值更接近,而净辐射通量则是NCEP1 ...

Comparison of air-sea heat fluxes calculated from national centers for enviromental prediction (NCEP) reanalysis data and moored buoy measurement data |
| |
| Abstract: | In this paper, the U.S. national centers for enviromental prediction (NCEP 1 and 2) reanalysis data and the data come from measurement of the moored buoy located in the north of the Yellow Sea are compared and the analysis shows that the NCEP reanalyzed marine meteorological parameters including the wind speed, humidity, air temperature and the ocean surface temperature are reliable. The marine meteorological parameters come from NCEP2 are more close to those come from the buoy measurement, while the net radiation flux computed from NCEP1 is more close to that comes from the buoy measurement. A more appropriate bulk algorithm to recalculate air-sea heat fluxes is recommended. The NCEP1 recalculated net heat flux is underestimated by 42% while the NCEP2 recalculated net heat flux is overestimated by 5% compared with buoy measurement data. The recalculated turbulent heat flux calculated using the combined wind field (the high wind speed is from NCEP1 while the low wind speed is from NCEP2) is much closer to the buoy measurement data. All these provide valuable information for how to select proper reanalysis data for Chinese ocean research. |
