elioe's tracks

I made seven tracks of Tropical Storm Bertha, before it was assessed as a tropical cyclone. I made two more tracks after that point. Additionally, within 480 hours of cyclogenesis, there were 45 instances, when I missed cyclogenesis entirely. All the detections of cyclogenesis were at excessively large lead times. As of this analysis, best track positions are available May 25, 18Z thru May 28, 12Z, 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". In the seven tracks (made before operationally recognized cyclogenesis), formation times ranged between May 22, 18Z and May 25, 18Z. Average was May 23, 2

I made 20 tracks of Tropical Storm Arthur, before it was assessed as a tropical cyclone. I made eight more tracks after that point. Additionally, within 480 hours of cyclogenesis, there were 37 instances, when I missed cyclogenesis entirely. At long lead times, non-detection was consistent, while at short lead times, detection was consistent, mostly with good timing of cyclogenesis. After detections began, assessment of peak intensity was very good. Position accuracy was also good. As of this analysis, best track positions are available May 13, 18Z thru May 19, 18Z, and as such, position comparisons are possible only for this timespan.
