Abstract

Due to the increased covering from satellites it is possible to find several sensors offering spatial information of the oceanic surface features as images obtained through different sensors such as visible, intensity, color infrared or microwaves (S.A.R.) (from satellites such as METEOSAT, NOAA, TOPEX, LANDSAT, ERS1 and ERS2). We use data from the altimeter and the SAR images from the ERS-1 as well as images from ERS- 2. SAR images and their analysis with flow visualization techniques uses correlations from SAR intensity that allow the calculation of maps of the spatial variation of integral scales. The integral scales which seem dominant, range between 15 and 20 Km showing a limit at the Rossby deformation radius. These larger lengths may be explained as micro and mesoscale vortex interaction in the surface of the ocean. They might also be related to barometric corrections caused by the mirror images produced by the atmospheric pressure on the atmosphere, but checking the weather maps at the same time confirms that atmospheric relevant lengthscales are much larger as a consequence of the larger Rossby deformation radius for atmospheric flows.
