Plain Language Summary: Polar mesocyclones (PMCs) genesis over the offshore west of Hokkaido is affected by the mountains at the eastern end of the Eurasian continent. In the experiment without the mountains, strong westerly from the continent blow over the southern part of offshore west of Hokkaido. Consequently, PMCs tend to make landfall earlier and before reaching maturity. In contrast, the low-level wind over the Strait of Tartary prior to PMC genesis is unaffected by the removal of the mountains. Thus, topographic effects are not important for PMC genesis in this region.
