WHY IT MATTERS
This historic rain streak highlights the impact of climate drivers on local weather patterns, emphasizing the need for continued monitoring and research into the effects of global climate change on regional weather events.
What happened
Central Tokyo has experienced 35 consecutive days of rainfall, breaking the previous record of 33 days set in 2019. The nonstop rains in September are due to a combination of a stationary autumn rain front and intensified typhoons.
Rainfall in central Tokyo in September reached 629 millimeters, nearly three times the typical monthly average.
