| Abstract | Analysis and measurement of wind characteristics are essential elements for examining the potential of coastal breeze across the shore. In this paper, the daily wind data for Pak Phanang (Lon 8?18.010 N / Lat: 100?15.842 E), over a period of 12 months (Sep 2011 August 2012), is modeled in terms of the Weibull distribution function, in order to determine wind characteristic of the location. The hourly, daily, monthly and annual wind speed probability density distributions at 100m, 80m and 60m meteorological height were focused using the data from theobservation mast installed at sea level. The annual mean wind speed, air density and annual mean temperature are determined with values of 5.18 m/s, 1.165 kg/m? and 26.6?c respectively at 100m height. The results confirm that while the wind speed is more concentrated during May to September, the distribution of turbulence occur during April and October which dramatically impact the overall wind speed that result in wind shear and gust along with major change in flow direction of wind. Further statistics suggest that this information can be used, with acceptable accuracy, for prediction of wind energy output needed for preliminary design assessment of wind turbine for the location. |
