【摘要】 通过对广东省阳江市海陵岛地区为期一年的铁塔观测资料进行分析,发现当风向为海风风向和陆风风向时,当地的风速廓线有很大差异,陆风风向阶段风随高度的切变较大,而海风风向阶段切变较小。因此在利用模式进行近海风能评估时,若能较好的利用风速廓线的性质,将大大提高近海风能评估的精确性,弥补观测资料不足所带来的缺憾。更多还原

【Abstract】 By analyzing the observation data of wind tower at Hailingdao in Yangjiang city of Guangdong province,the great difference of wind profile between blowing from sea and land was found.The wind speed shear when blowing from sea is smaller than blowing from land,so when calculate the wind resource along coastal areas using mesoscale model, the precision of wind resource assessment can be improved if the characteristics of wind profile can be better used.更多还原
