Reflection of the Oceanic Fronts on the Satellite Radar Images

摘要: Abstract The ocean surface sensing has been accomplished by Side Looking Radar (SLR) from a number of Cosmos and Ocean series satellites. SLR imagery the is map radar reflectivity 2–4 cm wavelength waves. (brightness image) depends on wind characteristics also hydrological inhomogeneities associated with oceanic fronts, currents eddies. This paper presents an analysis images Kuroshio confluence zone obtained in spring 1987 1988. Comparisons concurrent NOAA infrared images, weather maps ship data showed strong correlation between cross section σ° sea temperature (SST) when speed was range 2–3 to 8–10m/s A possible mechanisms which detects phenomena have discussed: variation may reflects change SST (due dependence kinematic viscosity water temperature), films concentration, air-sea difference, current shear through their modulation ambiguity be solved at different wavelengths.
