Structure and Dynamics of the Ras al Hadd Oceanic Dipole in the Arabian Sea

The Ras al Hadd oceanic dipole is a recurrent association of cyclone (to the northeast) and an anticyclone southwest), which forms in summer breaks up at end autumn. It lies near cape, southeast Arabian peninsula. Its size on order 100 km. Along axis this flows intense jet, Had jet. Using altimetric data eddy detection tracking algorithm (AMEDA: Angular Momentum Eddy Detection Algorithm), we describe life cycle over year (2014–2015). We also use results numerical model (HYCOM, HYbrid Coordinate Ocean Model) simulation, hydrological from ARGO profilers, to characterize vertical structure two eddies composing dipole, their variability 15 period. show that (1) before formed, will compose it, come different locations join Hadd, (2) remains during fall while wind stress (due monsoon wind) intensifies cyclone, (3) both reach depth Persian Gulf Water outflow, (4) horizontal radial velocity profile often close Gaussian but it can vary as interacts with neighboring eddies. As conclusion, further work process recommended quantify interaction surrounding atmosphere.
