This time, it did not snow as much as expected on the 13th in the plains of the Kanto region, such as the main rain in the 23 wards of Tokyo.


The Japan Meteorological Agency says that the reason for this is that the temperature did not drop during the time when it was expected to have the most snow.

The Japan Meteorological Agency said that there is a risk of heavy snowfall in Kanto Koshin, such as predicting that the amount of snowfall in the 23 wards of Tokyo will be 8 cm as of the 13th.



In fact, although it snowed along the mountains and part of the plains of Kanto Koshin, in the 23 wards of Tokyo, it was raining mainly with snow and sleet for a while.



The Japan Meteorological Agency believes that the reason for this was that the temperature did not drop as expected.



In central Tokyo, it was expected that the temperature would drop to 1 degree at 9 pm on the 13th and snow would accumulate, but in reality, the temperature at 9 pm on the 13th was 2.1 degrees and 0.9 degrees at midnight on the 14th. However, the situation continued to exceed once after that.



There are several possible reasons why the temperature did not drop, and we will consider it in detail in the future.



Kenichi Fuchibuchi, the forecaster of the Forecast Division of the Japan Meteorological Agency, said, "The south bank low pressure that brings snow to the plains of the Kanto region is very difficult to predict, and it may or may not fall more than expected. I will try to make a forecast, but if I think that it is necessary to call for caution in the forecast, I would like to convey a sense of crisis as well as this time. "
