Extreme rain in Japan and a tornado in France highlight the increasing frequency of severe weather events linked to climate change. Recent deluges in Japan's Ishikawa and Toyama prefectures caused flash floods and mudslides, while a rare tornado struck France, underscoring the global impact of shifting weather patterns.
Record Rainfall in Japan
Japan experienced unprecedented rainfall in mid-August, particularly in Chiba, followed by further extreme downpours. Moisture from the Sea of Japan brought relentless rain to Ishikawa and Toyama, with Himi recording 361.5mm in 24 hours—equivalent to half the average annual rainfall in London or Paris.
This extreme rain in Japan triggered river overflows, flash floods, and mudslides, damaging buildings and prompting mass evacuations. The Japan Meteorological Agency issued its highest-level rain and landslide warnings, leading to the evacuation of hundreds of thousands of people.
Typhoon Saudel's Impact
Before the recent downpours, Typhoon Saudel passed through Kagoshima and Okinawa Island, bringing winds of 100mph and extreme rainfall, with 230mm falling in a day in the Amami region. The storm was forecast to weaken as it moved toward southeast China.
Tornado in France
In a separate event, a tornado struck France, adding to the list of extreme weather phenomena across Europe. While tornadoes are rare in France, climate change is increasing the likelihood of such events by creating more unstable atmospheric conditions.
Climate Change Connection
The extreme rain in Japan and the tornado in France are consistent with climate change projections. Warmer oceans fuel more intense typhoons and rainfall, while shifting jet streams can lead to unusual weather patterns in Europe.
Experts note that developing El Niño conditions may be contributing to the increased storm activity near Japan, as warmer Pacific waters enhance typhoon formation and intensity.
Data Comparison: Rainfall Extremes
