Abstract
Satellite infrared images and coastal meteorological and oceanographic data are used to investigate the influence of weather and offshore conditions on spring thermal environment around the Sendai Bay in the Kuroshio/Oyashio frontal region. Sea surface temperature (SST) anomaly represents a high annual variation and a high correlation with those of the duration of sunshine and air temperature. The multiple regression analysis of SST with five-explanatory variables (weather variation components) provides a good correlation between the predicted value and in situ SST. Temporal behaviors of coastal SST and salinity show that water mass of the bay is closely connected with the advection of the Kuroshio/Oyashio. Analyses of SST images represent well the properties and durability of the Kuroshio/Oyashio interaction in the same year, and the low SST fluctuation at the inner area of the Sendai Bay and coastal area of the Oyashio flowing path. Empirical orthogonal function (EOF) analyses of monthly-averaged infrared images describe a spatial and temporal variability, which is consistent with in situ measurements. The first modes of the temporal variance, 91.6% (April) and 95.7% (May), show spatially varying offshore water-mass in the presence of the Kuroshio/Oyashio current.
