Abstract:Base on the TITAN products of SWAN and Technology of SafeShot Areas, the ground weather modification command system is build. In order to make the warning products and operational recommendations more timely and accuracy, the system improved the warning and operational product algorithm: (1) improved early warning algorithm to reduce the probability of missing warning, with the warning of the TITAN storm path extrapolation instead of TITAN area identification; (2) for the areas without weather radar, where there is a time lag in using the wholeprovince radar mosaic data, the data delay setting function is introduced to improve the timeliness and accuracy of weather modification operations. By improving the algorithm, the system can satisfy the demands of ground weather modification operations and has a certain popularization value.
