Satellite determination of the mesoscale variability of the sea surface temperature

Résumé

Satellite infrared data have been used to investigate the mesoscale variability of the SST (sea surface temperature) field. A statistical analysis of the SST field has been performed by means of the structure function. Results give the equivalent power-law exponent n of the spatial variance density spectrum E(k) ∼ k−h. The exponent n was found to vary from 1.5 to 2,3 with a mean value of 1.8 in the ]range of scales 3–100 km which is in agreement with previous one-dimensional analysis from shipborne and airborne measurements. These observed values of n are discussed and compared with the values predicted by turbulence theories.
