季节因素对长期订正的影响十分重要，随测风时间增加，风速订正不确定度会明显降低。 The influence of seasonal factors on long-term correction is important. As the wind measurement time increases, the wind speed correction uncertainty will be significantly reduced. 在进行长期订正时，不仅要注意风速的变化值，同时要注意K值的变化幅度，避免造成风功率密度产生较大差异。 In the long-term correction, to avoid a large difference in the calculation of the wind power density. Pay attention to the variation of the K value while paying attention to the change value of the wind speed.
