Review twelve-month atmospheric data and long-term averages for a representative point within the park boundaries.
Annual atmospheric patterns at Towada-Hachimantai National Park are defined by temperature, precipitation, and wind variations based on NASA POWER measurements collected between 1991 and 2020. These long-term averages illustrate the monthly climate rhythm at a single representative coordinate, providing baseline data for average maximum and minimum temperatures, relative humidity, and daylight availability throughout the calendar year.
