自动观测系统中VRB风向不定问题的探讨

Study on VRB variable wind in automatic meteorological observing system

风向不定是民航地面气象观测的一个重要组成部分。自动观测取代人工观测后可以更精确的测量记录风向数据,从而提高了对风向不定判定的准确度。探寻一个更科学、更完善的计算方法成为现阶段的要点。经过大量的实践和研究,总结出了几种算法,以供参考。

Wind direction is an important component in civil aviation meteorological observation. After automatic observation replacing the manual one, more accurate survey record data of wind direction were obtained, so as to enhance the accuracy of variable wind. To explore a more scientific, better algorithm becomes the point at present. After a lot of practice and research,several of algorithms were summed up,which made a reference for others.
