Ranking of 2022 Atlantic hurricane season predictions

As I'm writing this, post-season analysis has advanced to the point, that any changes in seasonal totals (14-8-2) are unlikely. The winner is clear: Congratulations Telford Holmes !!!!! The combined error is calculated as follows: sqrt( (E_ns)^2 / 12.1 + (E_hu)^2 / 6.4 + (E_mh)^2 / 2.7 )   where E_ns is error in number of nameable storms, E_hu is error in number of hurricanes and E_mh is error in number of of major hurricanes. The following has the format of ranking. / predicted named storms / predicted hurricanes / predicted major hurricanes / combined error / and Disqus/Twitter handle at time of giving prediction (possible Twitter account name in parentheses)  1. / 14   /  8 /  3   /  0.60858 / Telford Holmes  2. / 14   /  7 /  3   /  0.72569 / Rommel Gomez Vera (@habboerwin98)  3. / 16   /  8 /  3   /  0.83723 / elioe (@elioeFIN)  4. ...

Total verification of tracks done in 2021 in Eastern Pacific

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...

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

Image
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...
