“…The daily maximum SST appears during 1400–1600 LST in only 55.2% cases. It is consistent with the suggestion by Koizumi [1956] data that the peak temperature occurs around 1500 LST in summer and it occurs around 1300 LST in winter, which is confirmed from other in situ measurements too [ Kawamura et al , 2008; Gentemann and Minnett , 2008].…”

[1] An atmosphere-ocean mixed layer coupled model is developed to predict the diurnal variability of sea surface temperature (SST). For this purpose, a new mixed layer model is developed, which is able to reproduce realistic temperature profiles under the various atmospheric conditions, ranging from the formation of a diurnal thermocline under strong wind to the appearance of strong near surface stratification under weak wind. The predicted diurnal warming of SST (DSST) from the model is compared with satellite and buoy data in various aspects, including scatterplots, time series, and probability density functions of DSST, in order to examine the predictability. The model performance is also compared with other model results. In addition the diurnal variation of temperature profiles below the sea surface, whose information is not available from satellite data, is investigated based on model output.

“…7g). The southwestward sailing SD reached the northern primary SST peak at 05:40 and southern secondary peak at 12:20 in local sidereal time (LST) before the expected peak time of diurnal SST cycle (circa 13:00 LST) studied by Koizumi (1956). The SD-observed SST decreased with time toward noon.…”

Using an unmanned sailing vehicle, known as a Saildrone, we observed mesoscale and smaller scale structures of oceanic and atmospheric variables across the Kuroshio south of Japan during the winter of 2018/2019. From December 28 to December 29, 2018, the Saildrone crossed just north of the center of a very warm (∼23 • C) mesoscale spot in the Kuroshio centered around 31.5 • N, 135.8 • E. The northerly winter monsoon wind was intensified by ∼2 m s −1 over the mesoscale warm spot (MWS) and accompanied by a submesoscale sea level pressure undulation of ∼1 hPa possibly due to two oppositely rotating ageostrophic vortices. At this time, the wind reached a maximum speed of greater than 12 m s −1 and removed heat from the ocean at a rate of 1141 W m −2. Subsequently (January 3-5, 2019), the Saildrone observed weakening of wind and heat release to the atmosphere on the southern edge of the MWS, which was associated with the approaching low-pressure system over the Kuroshio. The observed submesoscale structures of atmospheric and oceanic variables near the center of the MWS suggest that the atmospheric boundary layer responded to the MWS through the pressure adjustment mechanism in the Kuroshio, where in situ high-resolution measurements have not been performed before.

“…4-4 explain these phenomena. According to Koizumi (1955) minimum water temperatures in 300 m and 400 m layers appear in March or April in other seas, for example on the ocean weather station " Extra " in the Pacific Ocean. But we can not conclude simply that phenomena in the Japan Sea are similar in the Pacific Ocean.…”
