“…Both the moisture flux convergence and moisture availability over adjacent oceans are important factors in heavy rainfall events [27,28]. The Yellow Sea is located on the west coast of the Korean Peninsula, a tide-dominated area with a complex coastal shape and many islands (Figure 1a).…”

A high-resolution Weather Research and Forecasting (WRF) model for a heavy rainfall case is configured and the performance of the precipitation forecasting is evaluated. Sensitivity tests were carried out by changing the model configuration, such as domain size, sea surface temperature (SST) data, initial conditions, and lead time. The numerical model employs one-way nesting with horizontal resolutions of 5 km and 1 km for the outer and inner domains, respectively. The model domain includes the capital city of Seoul and its suburban megacities in South Korea. The model performance is evaluated via statistical analysis using the correlation coefficient, deviation, and root mean squared error by comparing with observational data including, but not limited to, those from ground-based instruments. The sensitivity analysis conducted here suggests that SST data show negligible influence for a short range forecasting model, the data assimilated initial conditions show the more effective results rather than the non-assimilated high resolution initial conditions, and for a given domain size of the forecasting model, an appropriate outer domain size and lead time of <6 h for a 1-km high-resolution domain should be taken into consideration when optimizing the WRF configuration for regional torrential rainfall events around Seoul and its suburban area, Korea.

“…For example, Tsuguti and Kato (2014) discussed the effect of high SST in a case of heavy rainfall on an island south of Kyushu. A number of modeling studies have examined the relationship between SST variation and extreme or seasonal mean precipitation with relation to the CC effect (Manda et al 2014;Takahashi et al 2013). In the present study, therefore, analysis for SST was made in addition to air temperature (AT).…”

Long-term changes in extreme hourly precipitation in Japan were examined using data at 983 stations for 1979 to 2013, with relation to the variations in air temperature (AT) and sea-surface temperature (SST). According to the statistics over the whole country, annual maximum and 95 percentile precipitations show increasing trends of 2−4%/decade, whereas AT and SST have risen at a rate of 0.2−0.3°C/decade. Analysis for each region and season indicates that the increase in extreme precipitation is a nation-wide feature and is not limited to a single season. Moreover, year-to-year variations in extreme precipitation tend to be in phase with those of AT and SST, with a correlation coefficient of 0.5-0.6 on the annual basis, although negative correlation is found for the summer season in western Japan and the Nansei Islands.(Citation: Fujibe, F., 2015: Relationship between interannual variations of extreme hourly precipitation and air/sea-surface temperature in Japan.

“…The recent studies indicate the influence of the Kuroshio SST on the atmosphere of the ECS is as strong as other western boundary currents such as the Gulf Stream and Agulhas Current (e.g., Xie et al, 2004;Small et al, 2008). Evaporation from the sea surface in the Kuroshio region enhances the formation of convectively unstable air masses, which can produce deep convection Tsuguti and Kato, 2014;Manda et al, 2014;Kunoki et al, 2015;Sato et al, 2016). The Kuroshio also impacts the surface wind convergence, which in turn helps form the deep convective clouds (Xu et al, 2011;Sasaki et al, 2012;Miyama et al, 2012).…”

Abstract. This study analyzed CloudSat satellite data to determine how the warm ocean Kuroshio Current affects the vertical structure of clouds. Rainfall intensity around the middle troposphere (6 km in height) over the Kuroshio was greater than that over surrounding areas. The drizzle clouds over the Kuroshio have a higher frequency of occurrence of geometrically thin (0.5-3 km) clouds and thicker (7-10 km) clouds compared to those around the Kuroshio. Moreover, the frequency of occurrence of precipitating clouds with a geometric thickness of 7 to 10 km increased over the Kuroshio. Stronger updrafts over the Kuroshio maintain large droplets higher in the upper part of the cloud layer, and the maximum radar reflectivity within a cloud layer in non-precipitating and drizzle clouds over the Kuroshio is higher than that around the Kuroshio.
