Abstract
In this study, meteorological observations were conducted over a wide area and at multiple locations in northern Kyoto Prefecture from late October 2023, and the wind speed, duration, and frequency of Yuragawa arashi were clarified. The results showed that after sunset of the Yuragawa arashi, a clear pressure difference was observed at each location, with a maximum pressure of 1.7 hPa higher at Fukuchiyama than at the mouth of the river around 8:00 a.m. After sunset, the wind speed at the mouth of the river changed to the southerly direction and reached more than 5m/s from around 19:00, with a maximum of 6.6 m/s. Yuragawa arashi when the pressure difference between the Fukuchiyama Basin and the mouth of the Yuragawa is large.
