Comparative analysis of the long-term variability of the major large-scale climatic oceanic frontal zones (OFZ) based on the global satellite measurements of sea surface temperature (SST) is presented. High spatial resolution global SST data obtained from AVHRR measurements (monthly mean at approximately 4 km spatial resolution; PATHFINDER product) for the period 1982-2009 have been used. As an indicator of OFZ variability we used the magnitude of maximum meridional gradient of zonally averaged SST (Gmax) and meridional position of Gmax (OFZ core) for each OFZ. Time series of Gmax and its position for subpolar and subtropical OFZ in Atlantic and Pacific (both hemispheres) and in Indian Ocean and also for equatorial fronts in eastern Pacific have been investigated.
Keywords: sea surface temperature, oceanic frontal zones, long-term variability
