Gulf Stream path analysis
§ Isotherms typical of Gulf Stream
signature at different depths are
used to obtain frontal location.
§ Nearest neighbor connected
component  theory is used to
ascertain to continuity of the front
§ Frontal location derived from
every 3 day model output are
averaged to obtain mean frontal
position
