Verification of tracks made of Kevin

Image
I made ten tracks of Tropical Storm Kevin, before it was assessed as a tropical cyclone. I made two more tracks after cyclogenesis. Additionally, within 504 hours of cyclogenesis, there were seven instances, when I missed cyclogenesis entirely. As of this analysis, best track positions are available August 5, 18Z thru August 12, 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 ten tracks (made before operationally recognized cyclogenesis), formation times ranged between August 4, 12Z and August 9, 12Z. Average was August 7, 10Z and median was August 7, 18Z. In the eighteen cases (11 tracks...

Verification of tracks made of Ignacio

I made ten tracks of Tropical Storm Ignacio, before it was assessed as a tropical cyclone. I made two more tracks after cyclogenesis. Additionally, within 504 hours of cyclogenesis, there were seven instances, when I missed cyclogenesis entirely. As of this analysis, tropical cyclone report or best track positions are available July 30, 12Z thru August 4, 06Z, 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 ten tracks (made before operationally recognized cyclogenesis), formation times ranged between July 30, 12Z and August 3, 00Z. Average was August 1, 08Z and median was August 1, 15Z. In th...

Verification of tracks made of Jimena

Image
I made five tracks of Tropical Storm Jimena, before it was assessed as a tropical cyclone for the first time. I made three more tracks after the first cyclogenesis. Additionally, within 504 hours of the first cyclogenesis, there were fourteen instances, when I missed cyclogenesis entirely. As of this analysis, best track positions are available July 25, 12Z thru August 8, 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". In the five tracks (made before operationally recognized initial cyclogenesis), formation times ranged between July 29, 00Z and August 1, 00Z. Average was July 31, 05Z and median wa...

Verification of tracks made of Hilda

Image
I made twelve tracks of Hurricane Hilda, before it was assessed as a tropical cyclone. I made three more tracks after cyclogenesis. Additionally, within 504 hours of cyclogenesis, there were seven instances, when I missed cyclogenesis entirely. As of this analysis, best track positions are available July 28, 06Z thru August 6, 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 twelve tracks (made before operationally recognized cyclogenesis), formation times ranged between July 26, 12Z and July 31, 00Z. Average was July 28, 17Z and median was July 28, 21Z. In the nineteen cases (12 tracks, ...
