根据1994年9月18~30日南沙群岛海域渚碧礁的近海面大气湍流观测实验资料,分别计算了该海域光滑海面和粗糙海面上的空气动力粗糙度(z0 )、中性曳力系数( C D N)。利用 Butsaert 的假定,推导了求取标量粗糙度(z T、z Q)、整体输送系数(感热交换系数 C H N、水汽交换系数 C E N )的一组公式。在此基础上,分别计算和分析了该海域光滑海面和粗糙海面上空气动力粗糙度(z0 )、标量粗糙度(z T、z Q )、中性曳力系数( C D N)、整体输送系数(感热交换系数 C H N、水汽交换系数 C E N)及其关于水平风速分量的分布,并得到了一些有益的结论。
According to the observation data of near-surface atmospheric turbulence in Zhubi Reef, Nansha Islands waters from 18 to 30 September 1994, the aerodynamic roughness (z0), the neutral drag coefficient C D N). Based on Butsaert’s assumptions, a set of formulas for determining the scalar roughness (z T, z Q) and the overall transport coefficient (sensible heat exchange coefficient C H N, water vapor exchange coefficient C E N) are derived. On this basis, the aerodynamic roughness (z0), scalar roughness (z T, z Q), neutral drag coefficient (C D N), the overall transport Coefficient (sensible heat exchange coefficient C H N, water vapor exchange coefficient C E N) and its distribution about horizontal wind speed components, and some useful conclusions are obtained.
