I'm in the pink with Sakura

Sakura season, 2024 (Part 2)
~Sakura from prime blooming to farewell~
Why do cherry blossoms bloom at a certain time?
The science behind Japan’s cherry blossoms explains the "importance of winter."
- After
the flowers fall off, the tree makes new buds in summer.
- The
buds get into sleep in fall.
- Chill
air of winter wake them up to make themselves swell gradually
- When
spring comes and it gets warmer, the buds bloom.
Warm weather (above 15 degrees C) of March makes the buds open. So, I had thought that the cold weather of this March delayed the blooming about one week later than usual. That's right partly, but there is more significant reason.
Warm weather alone won't make the flowers bloom. They need enough cold spell of weather in winter to wake up in the spring. In January and February of this year, the winter cold was often interrupted by spring-like or even early-summer-like warmth. If our winter becomes more and more warm due to the climate change, I wonder what would become of Sakura blossoming in the southern part of Japan.
