2009年11月汕尾红海湾海面风场的观测分析
AN OBSERVATIONAL STUDY OF SEA SURFACE WIND FIELD AT RED BAY,SHANWEI IN NOVEMBER, 2009
摘要
Abstract
The sailing events of the 16th Asian Games Guangzhou 2010 will be held at the Guangdong Ocean Sports Training Centre, Red Bay, Shanwei in November 2010. Based on the buoy observation data in November 2009, the characteristics of wind field and its diurnal variation are examined. Combined with the pressure difference between sea and land, an indicator for surface wind forecasting is sought. The results showed that in November the prevailing winds over the venue of Red Bay are northerly and easterly winds and the average wind speed can reach 6.8m/s or so; the sea surface wind field at night is mainly associated with northerly winds, the easterly wind is prevailing during the day, the diurnal variation of wind direction is similar to the variation of cosine function. Wind speed does not show a significant diurnal variation, but in the afternoon between 1400-1800 LST it has fewer opportunities for weak or strong winds, which is the most suitable time for the contest. In November the surface wind at the venue can be divided into sea-land-, systematic turn- and cloudy-type, the percentages for the three types of wind field are 46.7%, 33.3% and 20%, respectively. The pressure difference between the buoy and Haifeng observation site has close relationship with the north-south component of the wind. It could be used as an effective forecasting indicator for the wind field.关键词
