“…In these areas, the societal preparation for heavy snowfall is insufficient because of few heavy snowfall events. In February 2014, extremely heavy snowfall due to the developed southern coastal extratropical cyclone hit the Kanto region (Honda et al 2016;Yamazaki et al 2015;Araki 2016;Ando and Ueno 2015;Iyobe et al 2015;Kawashima et al 2015), causing damages to urban and suburban functions. Yamazaki et al (2015) and Honda et al (2016) analyzed the atmospheric conditions of the heavy snowfall on February 14, 2014.…”

“…The spatial pattern of SAT shows that the low-SAT air was advected southwestward, which can be explained as the pulling by the low-pressure system. As Honda et al (2016) pointed out, cold air damming (CAD) may also contribute to the northerlies (Fig. S3).…”

This study investigated the impact of sea surface temperature (SST) on a snowfall event of late January 2018 on Kanto, Honshu, Japan, associated with an extratropical cyclone (southcoast cyclone) along the Pacific side, during the Kuroshio large meandering period by a regional atmospheric model. We addressed SST impacts on the snowfall event under almost the same synoptic-scale conditions, such as extratropical cyclone, in a framework of lateral boundary forcing. We conducted control experiments (KLM) with SST of the Kuroshio large meandering, and sensitivity experiments (NKLM) prescribed non-Kuroshio large meandering SSTs. Observational results showed that SST anomalies south of Tokai, and east of northern Kanto and Tohoku could be candidates to modify a snowfall event. As simulated results, timings of snowfall and precipitation associated with the extratropical cyclone was reproduced. Unlike what has been suggested, the SST impact south of Tokai on snowfall was not clear. However, the SST east of northern Kanto and Tohoku showed a significant impact. This impact was ex-2 Takahashi and Yamazaki, SSTs and snowfall in Tokyo plained by southward advection of modified air-mass from east of northern Kanto and Tohoku. Additional sensitivity experiments supported this result. This study implies the importance of the SST anomaly east of northern Kanto and Tohoku for snowfall in Tokyo.

“…Compared with studies on long-term trends in precipitation, few studies have addressed long-term trends in snowfall or the regional characteristics of these trends, much less those of heavy snowfall. Despite the scientific importance of these studies and the societal impact of these events, only a few researchers have examined heavy snowfall in Japan, such as Yamazaki et al (2015), Honda et al (2016), and Takahashi and Yamazaki (2020), who examined recent heavy snowfall occurrences over the Pacific coastal side of Japan.…”

The region of Japan along the Japan Sea is one of the heaviest snowfall regions in the world, and it appears to be increasingly vulnerable to climate variability and global warming. This study investigated the long‐term trends in snowfall characteristics and extremes (i.e., heavy snowfall) over Japan mainly using station observations over 51 years from the 1961/1962 to 2011/2012 winter seasons. Long‐term trends were examined in terms of total precipitation and the ratio of the numbers of snowfall days to precipitation days R(s/p). Our results show statistically significant decreasing trends in seasonally accumulated snowfall at most stations in Japan, except for those in northern Tohoku and Hokkaido Districts and the Pacific side of Japan. These significant decreasing snowfall trends were associated with the long‐term decrease in R(s/p). Although long‐term decreasing trends in R(s/p) were also observed over Tohoku District and Pacific side, increasing trends in precipitation cancelled the decreasing trends there, which indicates long‐term trends in precipitation likely complicated snowfall trends. Over Hokuriku District, a decrease in precipitation enhanced the decrease in snowfall. Moreover, major snowfall events occurred in the first half of the study period, whereas a recent increase in heavy snowfall was not yet evident.
