A Synoptic and Statistical Description of the Gulf Stream and Subtropical Gyre Using SOFAR Floats

摘要: Abstract Trajectories of 17 SOFAR floats ballasted to nominal depth 700 and 2000 m tracked for 15 months have been analyzed produce synoptic statistical descriptions the Gulf Stream subtropical gyre. launched in near along with positions surface satellite buoys demonstrate strong baroclinic shear. Nevertheless, horizontal patterns meanders rings are same at depth. Above thermocline, particle speeds greater than propagation speed cause parcels water move flow pattern. At depths, velocities most equal deep trajectories free pass through or ring. Strong temporal variability is found tail Grand Banks. Instances both southward into a narrow recirculation northward North Atlantic Current can ...
