中文摘要: 本文应用三种不同地表粗糙度条件下所取得的风、温廓线资料,计算了在大气近地面层中风廓线曲率β和理查孙数Ri的值。Ri和β的关系表明:在农田、草原和林网内1/2倍树高以下,虽然离散,但一致性较好;而林网内两倍树高处,在稳定层结时结果明显偏小。

Abstract:In this paper, values of Richardson Number (Ri) and the curvature of the wind profile(β) in the atmospheric near to the ground are calculated with the data obtained under three surface roughness conditions .The results show that the values of Ri and β appear scattering but agreeable over farmland, grassland and at the height to the middle of the tree within the forest-net, and the values are obviously smaller at the height twice of the tree within the forest-net as well as in the stable stratification
