The highest mountain in Japan usually receives a dusting of snow by early October, but this year has seen no snowfall due to abnormally warm temperatures.
According to the news agency, snow was first observed on the summit on October 5, 2023.
This year’s summer in Japan was the second-hottest on record, with average temperatures rising 1.76C (3.1F) from June to August.
Because of the higher northerly position of the sub-tropical jet stream, which allowed for a warmer southerly flow of air across Japan, September temperatures remained warmer than anticipated.
An air movement that moves quickly around the earth is called a jet stream. It happens when cooler air from the north collides with warmer air from the south.
Last month, about 1,500 locations saw “extremely hot” days, defined by Japan’s Meteorological Society as days with temperatures of 35°C (95°F) or more.
For rain to change to snow, the temperature must be close to freezing.
Although the heat has somewhat subsided in October, the month has nevertheless been warmer than usual.
However, since data was first gathered in 1894, the longest delay of the year for a snowcap on the summit is nearing November without any snowfall.
The previous record of October 26 was set in 1955 and 2016, according to forecaster Yutaka Katsuta at it.
