A Method of Extracting Post - Event Storm Tracks

3 Although existing storm tracking algorithms have been designed to operate in real-time, 4 they are also commonly used to carry out post-event data analysis and research. Real-time 5 algorithms can not use information on the subsequent positions of a storm because it is 6 not available at the time that associations between frames are carried out, but post-event 7 analysis is not similarly constrained. Therefore, it should be possible to obtain better tracks 8 for post-event analysis than what a real-time algorithm is capable of. In this paper, we 9 describe a statistical procedure to determine storm tracks from a set of identified storm cells 10 over time. We find that this procedure results in fewer, longer-lived tracks at the potential 11 cost of a small increase in positional error. 12
