This is a float reachability forecast, for a planned release on 03 June 0000Z, starting from a 4-day PE forecast (which covers the period May 30 - Jun 12).
Starting points are located in cyclonic Loop Current (LC) Frontal Eddy (FE) centers on 03 Jun 0000Z, as determined from water mass analyses. All runs assume 3 cm/s velocity unc., and run for 9 days.
In the plots below, the overlaid velocity vectors are those that the float "sees". This is a single velocity field constructed assuming that the float does two up/down profiles a day (0 to 1500m), each taking 8.5 hours and spends the rest of the day (7 hours) "parked" at 1500m. The resultant velocity field consists of the 17/24*(0-1500m vertically averaged velocity) + 7/24*(1500m velocity) field.
The float starting in the northwest cyclonic LCFE is forecast to slowly move SE but remain in the LCFE on the northwest flank of the LC, while the float starting in the east LCFE is forecast to move slightly SE but also remain entrained in the eddy.
