in this study, the capabilities of wawewatch-iii and mike21-sw for predicting the characteristics ofwind-generated waves in hormuz strait are evaluated. the numerical models have been set up using input data including gfs wind with 5° spatial resolution and 6 hours time intervals, along with the etopo1 bathymetry data with 2 arc-minute spatial resolutions. the results of the two model simulatio...

Retrieval of wind fields from a single-Doppler lidar with small azimuthal sectors is challenging. Both simpler retrieval algorithms such as Velocity Azimuth Display (VAD) or Volume Velocity Processing (VVP), and more sophisticated techniques such as Four Dimensional Variational Analysis (4DVAR) using VAD for mean velocities have limitations on small sectors of data. Narrow datasets may result i...

In this research paper, a 10 minute period measured wind speed data at 10 m, 30 m, and 40 m heights are presented for one of the major provinces of Iran. Four stations in Khuzestan- Abadan, Hosseyneh, Mahshahr, and Shushtar- are analyzed to determine the potential of wind power generation in this province. From the primary evaluation and by determining mean wind speed and also the Weibull f...

At present, the assimilation of u and v wind vector components calculated from wind speed (SP) and wind direction (DIR) observations (obs) is used as the only scheme for assimilating wind observations into the Weather Research and Forecasting Data Assimilation (WRFDA) three-dimensional variational data assimilation (3D-Var) system. The observational error of the u and v components is assigned b...

Understanding some of the basic wind engineering concepts helps one understand the chimney’s response. The circular cross section of the steel chimney characteristically provides aerodynamic lift perpendicular to the wind direction. Knowing how to predict and prevent these adverse responses is of critical importance to steel chimney design. I. STATIC WIND FORCES The force exerted by wind varies...

the main objective of this study is evaluation and wind statistic analysis, investigation of wind regime role on discharge flow and direction of sediments transferring in the case study. thus, sabzevar station anemometer data duration 10 years statistic period (1996-2005) analyzed. sand drift potential amount of study area is 160.9 v.u and result drift directionâ is west as well as sand flux is...
