“…The probability decreases the 1166 most in areas 5-6, between 900 and 1600 km from the Iberian margin. Therefore, the 1167 suggest that for a young and a strong meddy the effect is not used to be that drastic 1200 (Richardson et al, 2000;Bashmachnikov et al, 2009a). 1201…”

“…Farther away, between 1200 and 1600 546 km, the opposite tendency in meddy probabilities along these paths suggests a reverse 547 migration of meddies along the northern slope of the Azores plateau. One such 548 translation has been observed byBashmachnikov et al (2009a). 549There are also several indications of meddies leaving the Northern path section, we study how meddy characteristics vary with respect to their distance 558 from their region of generation along the Iberian coast.…”

“…Richardson et al, 2000, Bashmachnikov et al, 2009). An eddy-seamount collision may result in a drastic change in looping characteristics of an eddy and change in both temperature (Richardson et al, 2000) and salinity (Bashmachnikov et al, 2009) of the core properties. Eddies may split (Cenedese, 2002), become hetons (Hogg and Stommel, 1985), or may be destroyed (Richardson et al, 2000).…”

“…Several studies have explored the interaction of submesoscale vortices with isolated topography, both using laboratory experiments (e.g., Cenedese, 2002, Dewar, 2002, Adduce and Cenedese, 2004, or with observations (float and CTD) data (e.g. Richardson et al, 2000, Bashmachnikov et al, 2009).

The Gulf of Aden (GOA) in the northwestern Indian Ocean is the receiving basin for Red Sea Outflow Water (RSOW), one of the World's few high-salinity dense overflows, but relatively little is known about spreading pathways and transformation of RSOW through the gulf. Here we combine historical data, satellite altimetry, new synoptic hydrographic surveys and the first in situ direct observations of subsurface currents in the GOA to identify the most important

“…Core properties of meddies also change when they interact with seamounts. Such interactions can range from "elastic", when the eddy only slightly changes its trajectory, to "drastic", when the eddy is split into several parts or destroyed after interaction with the seamount (Van Geffen and Davies, 2000;Richardson et al, 2000;Bashmachnikov et al, 2009b).…”

Abstract. Meddies, intra-thermocline eddies of Mediterranean water, can often be detected at the sea surface as positive sea-level anomalies. Here we study the surface signature of several meddies tracked with RAFOS floats and AVISO altimetry.While pushing its way through the water column, a meddy raises isopycnals above. As a consequence of potential vorticity conservation, negative relative vorticity is generated in the upper layer. During the initial period of meddy acceleration after meddy formation or after a stagnation stage, a cyclonic signal is also generated at the sea-surface, but mostly the anticyclonic surface signal follows the meddy.Based on geostrophy and potential vorticity balance, we present theoretical estimates of the intensity of the surface signature. It appears to be proportional to the meddy core radius and to the Coriolis parameter, and inversely proportional to the core depth and buoyancy frequency. This indicates that surface signature of a meddy may be strongly reduced by the upper ocean stratification. Using climatic distribution of the stratification intensity, we claim that the southernmost limit for detection in altimetry of small meddies (with radii on the order of 10-15 km) should lie in the subtropics (35-45 • N), while large meddies (with radii of 25-30 km) could be detected as far south as the northern tropics (25-35 • N). Those results agree with observations.
