Applied hydromechanics, Vol. 10 (82) ¹ 4, (2008) |
| The mathematical model is proposed and a stream function approximated a meandering jet of Gulf Stream is found. This function is a modification of the stream function describing the Karman's vortex street. The modification which is introduced allows to approximate main patterns in a meandering jet of Gulf Stream. This stream characterizes by the following coherent structure elements in a coordinate frame moving with a speed of the meander: 1) an eastward-propagating meandering jet; 2) regions of recirculating fluid below and above meander crests and troughts; 3) regions of westward-propagating fluid below and above the jet and recirculation regions. |
