| 摘 要： | 利用2009年东莞市气象台涡动能量平衡观测系统的观测数据和常规观测数据,利用一元线性回归的方法对感热交换系数进行估算。结果表明,感热交换系数具有明显的季节变化,春季的感热通量交换系数相对较大,而夏、秋两季的感热交换系数则相对较小。近地面风速越大,感热交换系数越小。华南地区感热交换系数一般在(3.26±1.55)×10-3的范围。 |
| 关 键 词： | 感热通量 感热交换系数 华南 |

| Abstract: | The data collected by the eddy covariance energy balance observation system and the conventional meteorological data of Dongguan Observatory in 2009 are used in this paper to estimate the transfer coefficient of sensible heat (Ch) through the simple linear regression method. The result shows that the Ch has conspicuous seasonal variation. The Ch value is large in spring and small in summer and autumn. When the near surface wind speed gets larger, the Ch becomes smaller. The range of Ch in southern China is (3.26±1.55) ×10-3 |
| Keywords: | sensible heat flux transfer coefficient of sensible heat flux southern China |
