The invention discloses an early warning method for rapidly identifying sudden decrease of visibility, and belongs to the technical field of meteorological early warning. Comprising the following steps: S1, selecting low clouds, wind directions, wind speeds, rainfall, absolute values of warm water differences, haze, floating dust and special weather as main meteorological factors influencing sudden reduction of visibility; s2, determining a threshold value and a coefficient of the influence of each meteorological element on the visibility sudden drop; s3, establishing a visibility sudden drop early warning model; and S4, obtaining current meteorological element observation data by using observation equipment, substituting the current meteorological element observation data into the early warning model to obtain a result, and performing disposal according to an early warning result. According to the invention, by establishing the early warning model, the trend of sudden reduction of visibility can be identified more quickly and accurately, and the test flight safety and efficiency are effectively improved.

    本发明公开了一种快速识别能见度突降的预警方法,属于气象预警技术领域。包括S1、选取低云、风向、风速、降水、温水差的绝对值、霾、浮尘、特殊天气作为影响能见度突降的主要气象因素;S2、确定各气象要素对能见度突降影响的阀值和系数;S3、建立能见度突降预警模型;S4、使用观测设备获取当前的气象要素观测数据,将其代入预警模型中得出结果,根据预警结果进行处置。本发明通过建立预警模型,可以更加快速、准确的识别能见度突降的趋势,有效的提升试飞安全和效率。
