The invention provides a calculation method for an independent hill terrain wind speed correction coefficient. The calculation method is characterized in comprising the following steps that: S1: measuring massif total height H, wherein unit is m; S2: measuring a windward slope massif slope [Alpha], wherein unit is angle; S3: measuring windward slope building position earth surface altitude heightz, wherein unit is m; and S4:substituting the massif height, the massif slope and the building position earth surface altitude height into a formula, and carrying out calculation to obtain a wind degree correction coefficient. The invention aims to provide the calculation method for the independent hill terrain wind speed correction coefficient by aiming at a calculation way that a correction coefficient is directly one in the prior art, the deficiency of an existing specification is made up, and the calculation accuracy of the hill terrain is improved.
Description
technical field [0001] The invention relates to the technical field of mountain wind research, in particular to a method for calculating wind speed correction coefficients on windward slopes of independent hill topography. Background technique [0002] Among all kinds of micro-topography in nature, terrain such as independent hills, uplifts, passes, and canyons will have a greater impact on wind speed. Scholars at home and abroad have done a lot of research and discussion on the acceleration effect of mountain wind in terms of observation, theoretical analysis and numerical simulation calculation, and have also achieved many meaningful results. [0003] It is the most direct and effective method to conduct wind observation experiments in the real natural wind environment. In the 1980s, a number of on-site wind measurement experiments were carried out abroad, mainly including the Montenegro experiment, Blashaval Hill experiment, Askervein Hill experiment, Kettles Hill and Hj...
