Eddy characteristics in the South Indian Ocean as inferred from surface drifters
Using a geometric eddy identification method, cyclonic and anticyclonic eddies from submesoscale to mesoscale in the South Indian Ocean (SIO) have been statistically investigated based on 2082 surface drifters from 1979 to 2013. A total of 19 252 eddies are identified, 60 % of them anticyclonic eddies. For the submesoscale eddies (radius r < 10 km), the ratio of cyclonic eddies (3183) to anticy...
متن کاملA Mathematical Model for Indian Ocean Circulation in Spherical Coordinate
In recent years, the Indian Ocean (IO) has been discovered to have a much larger impact on climate variability than previously thought. This paper reviews processes in which the IO is, or appears to be, actively involved. We begin the mathematical model with a pattern for summer monsoon winds. Three dimensional temperature and velocity fields are calculated analytically for the ocean forced by ...
متن کاملFronts in the Southern Indian Ocean as inferred from satellite sea surface temperature data
Sea surface temperature (SST) derived from the weekly measurements made by the Advanced Very High Resolution Radiometers (AVHRR) of NOAA satellites was used to investigate the structure and space-time variability of large-scale fronts in the Southern Indian Ocean (30–60jS and 20–150jE) during the period of 1997–1999. Monthly SST gradient maps provided an overall view of five basic fronts: the N...
متن کاملSurface Circulation at the Tip of the Antarctic Peninsula from Drifters
An array of 40 surface drifters, drogued at 15-m depth, was deployed in February 2007 to the east of the tip of the Antarctic Peninsula as part of the Antarctic Drifter Experiment: Links to Isobaths and Ecosystems (ADELIE) project. Data obtained from these drifters and from a select number of local historical drifters provide the most detailed observations to date of the surface circulation in ...
متن کاملEstimates and Implications of Surface Eddy Diffusivity in the Southern Ocean Derived from Tracer Transport
Near-surface “effective diffusivities” associated with geostrophic eddies in the Southern Ocean are estimated by numerically monitoring the lengthening of idealized tracer contours as they are strained by surface geostrophic flow observed by satellite altimetry. The resulting surface diffusivities show considerable spatial variability and are large (2000 m s ) on the equatorward flank of the An...
