The invention relates to the technical field of flexible direct current power transmission, and particularly provides a method and a device for identifying turning weather causing wind power output characteristic change, comprising the following steps: substituting meteorological characteristic parameter data of a to-be-analyzed area in an analysis period into a pre-fitted turning weather identification function, calculating a turning weather identification coefficient of the to-be-analyzed area in the analysis time period; and identifying whether the weather of the to-be-analyzed area in the analysis time period is turning weather or not based on the turning weather identification coefficient of the to-be-analyzed area in the analysis time period. The technical scheme provided by the invention has the characteristics of simplicity, rapidness, high accuracy, good universality and good robustness. 本发明涉及柔性直流输电技术领域，具体提供了一种引发风电出力特性改变的转折性天气识别方法及装置，包括：将待分析区域在分析时段的气象特征参数数据代入预先拟合的转折性天气识别函数，计算待分析区域在分析时段的转折性天气识别系数；基于所述
