This spring, the cherry blossom day in many parts of Japan set or flattened the earliest record since the formal observation record was established in 1953. After analyzing the records of Kyoto cherry blossoms in historical documents, Japanese researchers found that the full blooming day of Kyoto cherry blossoms this year was also the earliest year in which there were related written records in about 1,200 years.
newsupd.com reported that the Japan Meteorological Administration recently announced that the cherry blossom day in Tokyo this year will be March 14th, which is tied with 2020 as the earliest record since the formal observation record was established in 1953. The Kyoto Regional Meteorological Observatory recently announced that the flowering day and full blooming day of the cherry blossoms in Kyoto this year will be March 16 and 26 respectively, both of which are the earliest records since 1953. In addition, local weather stations in Hiroshima, Osaka, and other places also announced the earliest cherry blossom day since the observation records.
Before 1953, Japan had no formal observational statistics of cherry blossoms, but there were many records in Japanese historical documents about the cherry blossoms in Kyoto, the ancient capital of Japan. Japan’s Osaka Prefecture University Associate Professor Yasushi Aoye and others studied a large number of historical documents and found that the earliest written record of the full bloom of cherry blossoms in Kyoto can be traced back to 812 AD. It can be seen from the literature that most of the Kyoto cherry blossom dates in history are in April, and many years are in late April, and sometimes even in early May. According to the researchers, this year’s cherry blossoms in Kyoto this year are the earliest year of about 1,200 years with related written records.
Although these ancient written records are not formal observation records and are not coherent, the researchers believe that they can try to count the seasonal changes of plants such as the cherry blossom day based on ancient documents, and perhaps further speculate on the temperature changes at that time. Wait.
