| 摘 要： | 本文利用2006年3~5月珠江口的海气热通量观测资料,结合NCEP再分析资料,分析了块体动力学在不同天气系统影响下计算海气热通量的特点,以及相对较准确的涡旋相关法的相对误差估计。结果表明,在海面为相对低压控制区域时,块体动力学计算的通量异常偏低,相对误差约为潜热通量95.8%;感热通量205.8%;在高压控制下,计算有所高估,相对误差约为潜热通量275.6%;感热通量156%。因此,利用块体法计算海气通量时,应注意根据不同天气系统特点对块体通量系数进行调整。

| Abstract: | This paper analyzed the air-sea heat flux on Maoming observation platform in the South China Sea,and NCEP re-analyzed data,studied the features of flux gradient method in different weather system and found out the relative error compared with eddy correlation method.The results showed that the air-sea heat flux was small in low pressure region,and it was larger than that in high pressure region by flux gradient method.The relative error was concerned with wind speed and temperature difference between air an... |
