Abstract：The monthly changing characteristics of aerodynamic roughness z0 and the re-lationship between z0 and the average wind speed at 10 meters above the ground are in-vestigated by using the wind data observed on a 100-meter-high wind energy tower loca-ted at the Caofeidian Port on the northern coast of the Bohai Bay from June 2012 to May 2013.The results have indicated that because of the influences of seasonal changes in land and sea breeze and surrounding environment the z0 on the northern coast of the Bo-hai Bay varies monthly and significantly.By using fitting methods,equations are built up between the z0 and the 10min average wind speed at 10 meters above the ground in the sea-land and the land-sea breeze directions.The gradient wind speed calculation tests have indicated that the above two equations are stable and practicable.Based on all the above conclusions,a fixed point and quantitative horizontal wind load forecasting model for port cranes is designed and established for the requirements of fine weather service support for safety operation dispatching of the port.The results from the tests of the forecasting model and the program developments have shown that the forecasting model thus established is correct,feasible and even more suitable for the risk forecasting service.
