| Summary: | activity remains almost the same if only the annual harmonic almost no eddies. The formation of eddies during periods of and travel more than 250 of longitude toward the west. as unstable mean flows, for the formation of the eddies. background flow. Eddies formed in September or October coast of Central America. Plots of eddy tracks from TOPEX data show that some of these eddies last for over 6 months dissipate rapidly. These eddies do not travel south beyond Eddies generated in January show properties between these two eddy formation in the eastern tropical Pacific. Eddy encounter a strong westward flowing current and do not Experiments done to study the propagation of the eddies show experiments exploring the formation mechanism show that high extreme cases. frequency wind bursts are sufficient but not necessary for General Circulation Model is used to study the formation and interannual variations in eddy activity. Comparisons between longitude. Eddies formed in March and April encounter a model with only the high frequency wind component produces not all eddies are caused by winds blowing offshore from the Observations of eddies in the eastern tropical Pacific from of the wind field is used to force the model. Forcing the Others go more towards the equator and dissipate quickly. A propagation aspects of these eddies. Results from strong eastward flow dissipate quickly and propagate towards than 6 months and travel westward for more than 250 of than four months and cover less than 150 of longitude. that the eddies are greatly affected by the structure of the the equator where they disappear. These eddies last for less the region of shear between the currents. They last for more time of eddy formation and corresponding wind data show that TOPEX altimetry data show that there are seasonal and weak offshore winds suggests other possible mechanisms, such |
