Verification of East Pacific ghost storm tracks of June-July 2019


I falsely detected tropical cyclogenesis in East Pacific (north of the equator and east of 140W longitude) 19 times in June and July of 2019. Tracks were made of five systems.

In the calculations, crossover into Atlantic as a tropical cyclone is considered equal to dissipation, and crossover from Atlantic as a tropical cyclone is considered equal to formation or regeneration. Exiting the East Pacific tracking map through its left edge is also considered equal to dissipation.
At the lead time of 1 day (24 hours), there were 0 false detections.
At the lead time of 2 days (48 hours), there was 1 false detection.
At the lead time of 3 days (72 hours), there were 0 false detections.
At the lead time of 4 days (96 hours), there was 1 false detection.
At the lead time of 5 days (120 hours), there was 1 false detection.
At the lead time of 6 days (144 hours), there was 1 false detection.
At the lead time of 7 days (168 hours), there was 1 false detection.
At the lead time of 8 days (192 hours), there were 4 false detections.
At the lead time of 9 days (216 hours), there were 5 false detections.
At the lead time of 10 days (240 hours), there were 4 false detections.
At the lead time of 11 days (264 hours), there were 9 false detections.
At the lead time of 12 days (288 hours), there were 9 false detections.
At the lead time of 13 days (312 hours), there were 5 false detections.
At the lead time of 14 days (336 hours), there were 6 false detections.
At the lead time of 15 days (360 hours), there were 7 false detections.
At the lead time of 16 days (384 hours), there were 8 false detections.
