Hazardous weather, such as thunderstorms, is one of the primary causes of airspace congestion in summer. A scientific and accurate assessment of the dynamic capacity of the terminal area is required to promote the balance between airspace capacity and traffic flow. First, the dense inverse search (DIS) optical flow algorithm was selected for thunderstorm echo extrapolation over the next 0~2 h. Based on this prediction, restricted flight areas were delineated dynamically. Subsequently, a terminal area network was established. Control transfer points, the airport, and restricted areas were set as nodes, and flyable paths were defined as arcs. The maximum flow of the network was determined using the max-flow min-cut theorem. Finally, the capacity in various directions and the total capacity were calculated by altering the positions of source and sink points. The results indicate that the DIS optical flow algorithm effectively captures the random generation and dissipation of thunderstorms. Combined with the semi-Lagrangian extrapolation scheme, the method quantifies the impact of weather evolution on airspace capacity. The predicted flight restricted areas are more precise than those from traditional methods, enabling a rolling assessment of dynamic terminal capacity for the next 0~2 h at 6-minute intervals.

当前危险天气的临近预报多采用主客观结合模式,其中主观依赖人工经验,客观包括风暴单体识别与跟踪(storm cell identification and tracking,SCIT)、雷暴识别、跟踪、分析与临近预报(thunderstorm identification, tracking, analysis and nowcasting,TITAN)、相关回波跟踪连续性(continuity of tracking radar echoes by correlation,COTREC)、光流法及深度学习等识别与外推算法。其中,DIS算法由Kroeger等[25]于2016年提出,是一种改进的稠密光流法。相比传统质心或相关追踪等算法,该算法引入了多尺度分块逆向搜索策略,可快速模拟接近理想的稠密运动矢量场,更适合危险天气的识别、追踪与雷达回波外推[26-27]。
