Research on Synop eddy currents (large size) in the East Vietnam Sea
The field survey to determine the size, location, morphology and time of appearance of Synop vortexes in the East Vietnam Sea is not feasible in the current conditions of our country. The East Vietnam Sea stretches over 25 degrees latitude, with the main climate and weather conditions of the tropics, with monsoon and equator, so the possibility of the appearance of Synop vortexes is entirely possible. Indirectly studying the Synopic vortexes of the East Vietnam Sea, using the research model, has also obtained certain results. Recently, a number of ocean circulation models have developed strongly of three-dimensional modeling problems, the models have applied effective calculations on the seas and world oceans of Synopic processes without also describes oceanic spectra ranging from small to global in size, ranging in duration from a few seconds to thousands of years. Using the calculated ROMS (Regional Ocean Modeling System) model, the current field in the East Vietnam Sea appears many different large-sized vortex shapes. There exists a large vortex pattern covering several small internal vortices. The vortex may appear only in the western part of the East Vietnam Sea, or only in the eastern part of the East Vietnam Sea. There exist contiguous double vortices, this double vortex is usually two reversible vortices, the belt of eddies flows continuously in opposite directions from west to east or from east to west. Comparing the research results with other research results published by foreign authors shows that there is a concordance.
