Research Abstract

We investigated diurnal variation of ocean surface meteorological parameters such as wind speeds, sea surface temperature and so on. Buoy and satellite observation data are used in this study. We carried out construction of Daily Mean March data, harmonic analysis and spectrum analysis for buoy data. The amplitudes and phase of diurnal and semi-diurnal variations are clarified for various meteorological parameters. Moreover, we investigated possibility of construction of high-temporal resolution data by use of multi-satellites data.
