Cold weather is expected to return this weekend, but the warmth of spring will gradually approach. Even into April, temperatures are expected to remain normal or warm across the country, which is expected to boost bud growth.

* Breaking dormancy: The flower buds that formed and entered the dormant state in the previous summer will wake up after being exposed to low temperature for a certain period of time in winter.

A2: Same as the observation standard of the Japan Meteorological Agency. The flowering day is the first day when more than 5 to 6 flowers bloom on the specimen tree, and the blooming day is the first day when more than 80% of the flower buds on the specimen tree are open.

the third quater: What is the expected number of points?

The 89 forecast points are 53 sample trees observed by the meteorological station in various regions, and 36 points can obtain observation data from local governments, parks and other cooperative institutions.

fourth quarter: What are the methods and features of the cherry blossom forecast of the Japan Meteorological Association?
A4: We use our own prediction formula to predict flowering, focusing on the “post-autumn temperature process”, which has a great influence on the growth process of flower buds. It is characterized by forecasting based on meteorology, emphasizing accurate observation data through cooperative institutions such as specimen trees and local meteorological observatories and parks.
The Japan Meteorological Association has been forecasting cherry blossoms since 2007, and this year marks the 16th year of the initiative.

Q5: What data do you use to predict flowering?
A5: Use the following data.

  • Temperature observations from the autumn of last year to the day before the expected working day
  • Temperature forecast from forecast working days to flowering time (Japan Meteorological Association point forecast and long-range forecast)

The temperature from autumn to spring of the previous year greatly affects the flowering time of cherry blossoms. Cherry blossom buds form in the summer of the previous year and then go dormant. Exposure to low temperatures for a period of time in winter, buds wake up from dormancy (break dormancy). After waking from dormancy, it grows and blooms with warmer temperatures, but it is thought that the higher the temperature, the faster the buds will grow and the faster they will bloom.
