Verification of tracks made of Ana
I made no tracks of Tropical Storm Ana, before it was assessed as a subtropical cyclone. I made three tracks after cyclogenesis. Additionally, within 504 hours of cyclogenesis, there were 28 instances, when I missed cyclogenesis entirely. As of this analysis, best track positions are available May 19, 00Z thru May 24, 00Z, and as such, position comparisons are possible only for this timespan. Since I give only SSHS categories in my tracks, I don't calculate intensity errors in units of speed, but in categories. For this purpose, I define tropical or subtropical storms as "Category 0", tropical or subtropical depressions as "Category -1" and non-existence of a tropical or subtropical cyclone as "Category -2". Statistics about formation time are not applicable. In the 28 cases (0 tracks, before the tracks and data agreed, that (sub)tropical storm would remain the peak intensity, and 28 complete misses), range, average and median of peak inte...
