In Japan, the spring bloom of cherry blossoms is an annual riddle of celebration, along with picnics and parties under flowering canopy.

But this week, an odd thing happened: some of the trees flourished again. In autumn

the Japanese transmitter NHK reported that a weather company had received hundreds of reports that the trees bloom across an area stretching from Kyushu in southwestern Japan to Hokkaido in the north.

The obvious cause? The two typhypes who hit the country in September and early October.

“Storms of the year hit large regions and the strong winds could have caused the flower,” said the surgeon Hiroyuki Wada to the transmitter. “I’ve never seen anything like this.”

Wada explained that a popular variety of cherry blossoms, the Yoshino cherry, buds in the summer but usually does not bloom because a hormone like the tree leaves leaves the buds evolving.

But this year many leaves were removed from the powerful typhones – resulting in strong winds and salt exposure that caused dampening. Heat temperatures followed, which further encouraged the buds to bloom.

Fortunately, blooming in the high season is not expected to affect spring bloom.

The spring bloom of cherry blossoms in Kyoto has been documented for more than 1,000 years, as Washington Post reported last year. By earning over diaries and chronicles of emperors, aristocrats and monks, a professor at Osaka Prefecture University named Yasuyuki Aono, a date of flowering dates for cherry blossoms, dates back to 801.

Most of the flower dates were quite consistent. But since 1850 the flowering date has been driven earlier and earlier. The same trend has been documented by the National Park Service since 1921 in Washington, DC, home to 3000 cherry blossoms given by Japan.

“In both Kyoto and Washington, warming and previous flowering are probably dependent on a growing urban heat effect and increasing concentrations of greenhouse gases in the atmosphere,” meteorologist Jason Samenow explained in Post .
