Total verification of tracks done in 2021 in Eastern Pacific

Image
Above: Possibly the most ridiculous Eastern Pacific track of 2021. No, Kevin didn't reach 215 mph winds... These tracks, or lack of those, have been earlier discussed in separate blog entries system-wise or time-wise: Andres Blanca Carlos Dolores Enrique Felicia Guillermo Hilda Jimena Ignacio Kevin Linda Marty Nora Olaf Pamela Rick Terry Sandra ghost storms Jan-May ghost storms Jun-Jul ghost storms Aug-Oct ghost storms Nov-Dec In 2021, I analysed 328 model cycles. I made 158 tracks of storms, that actually formed later. I made 105 tracks of ghost storms. I missed 150 times cyclogenesis, which actually happened within 504 hours. At the lead time of 1 day ( 24 hours), there were 30 hits, 15 false detections and 5 misses. 43 available position comparisons produce an average error of 53 nautical miles. At the lead time of 2 days ( 48 hours), there were 41 hits, 17 false detections and 2 misses. 49 available position comparisons produce an average error of 82 nau

  Above: Possibly the most ridiculous Atlantic track of 2021. Yes, Sam became strong. But 200 mph? Nah.

I made 60 tracks of storms, that actually formed later. I made 110 tracks of ghost storms. I missed 249 times cyclogenesis, which actually happened within 504 hours. At the lead time of 1 day ( 24 hours), there were 22 hits, 9 false detections and 7 misses. 31 available position comparisons produce an average error of 59 nautical miles. At the lead time of 2 days ( 48 hours), there were 20 hits, 22 false detections and 12 misses. 39 available position comparisons produce an average error of 92 nautical m

Verification of East Pacific ghost storm tracks of November-December 2021

I falsely detected (sub)tropical cyclogenesis in East Pacific (north of equator and east of 140 degrees west) 3 times in November thru December of 2021. Tracks were made of 1 system. 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 0 false detections. At the lead time of 3 days ( 72 hours), there was 0 false detections. At the lead time of 4 days ( 96 hours), there were 0 false detections. At the lead time of 5 days ( 120 hours), there were 0 false detections. At the lead time of 6 days ( 144 hours), there were 0 false detections. At the lead time of 7 days ( 168 hours), there were 0 false detections. At the lead time of 8 days ( 192 hours), there were 0 false detections. At the lead time of 9 days ( 216 hours), there were 0 false detections. At the lead time of 10 days ( 240 hours), there were 0 false detections. At the lead time of 11 days ( 264 hours), there was 1
