December 14, 2023 12:58
Yesterday, the 13th, the Japan Weather Association announced the outlook for winter snow at ski resorts. The amount of snowfall at ski resorts this winter will be at or below normal in northern and eastern Japan, and less than normal in western Japan. There is also the possibility of a temporary increase in snowfall due to strong cold air and low pressure in the upper atmosphere.
Snow at ski resorts this season tends to be at or below normal levels
Yesterday, the 13th, the Japan Weather Association announced the outlook for winter snow at ski resorts.
The amount of snowfall at ski resorts in the winter of 2023 to 2024 will be around or below normal in northern and eastern Japan, and below normal in western Japan.
This winter, due to the El Niño phenomenon, it will be difficult for cold air to flow into the Japanese archipelago, and temperatures across the country will be at or above normal. However, there will be days when the atmospheric pressure will temporarily become winter-like in northern Japan, and there will be periods when cold air flows in. Currently, seawater temperatures in the Sea of Japan are higher than normal, so if cold air flows in, there is a possibility of heavy snow.
Snowfall on the Sea of Japan side is expected to be at or below normal in northern and eastern Japan, and below normal in western Japan. At many ski resorts, snowfall is expected to be at or below normal. At ski resorts in areas with many sunny skies in winter, low pressure systems tend to pass near Japan, and when low pressure systems pass over the Pacific coast, there is a possibility of temporary increases in snowfall. However, temperatures will be higher than average, so heavy, wet snow is expected.
Snow situation and outlook this winter
Until the first half of December, there were some days with record high temperatures, but from the second half onwards there are expected to be days when strong cold air flows in. Strong cold air will intermittently flow in until about the 23rd. Due to the sea temperature on the Sea of Japan side being higher than normal, there is a possibility of temporary heavy snowfall.
Characteristics of monthly atmospheric pressure distribution Snow outlook
<1月の雪の見通し>
There will be some days when the atmospheric pressure will be in a winter-like pattern, but this will not last long and the inflow of cold air is expected to be weak. Therefore, it is expected that there will be less snowfall on the Sea of Japan side. It is also possible that the snow will be wetter than usual. Additionally, at ski resorts where there are many sunny days in the winter, a low pressure system is expected to pass over the southern coast of Honshu, leading to days when a lot of wet snow will fall.
<2月の雪の見通し>
There will be days when the atmospheric pressure will be in a winter-like pattern centered in northern Japan, and strong cold air will flow in. For this reason, there is a possibility that there will be a lot of snow mainly on the Sea of Japan side of northern Japan. However, the winter-like atmospheric pressure pattern is not expected to last long. On the other hand, at ski resorts where there are many sunny days in the winter, a low pressure system is expected to pass over the southern coast of Honshu, and there will be days when there will be a lot of wet snow.
<3月の雪の見通し>
There will be fewer days than usual with winter-like atmospheric pressure patterns, and the flow of cold air will be weaker. Snowfall on the Sea of Japan side is also expected to be less than normal. At ski resorts where there are many sunny days in the winter, there will be days when a low pressure system will pass over the southern coast of Honshu, resulting in wet snow.
