Expert Analysis
“Pre‐monsoon western disturbances are becoming more active due to changing sea‐surface temperatures, which can intensify these rain spells,”
— Dr. Roxy Mathew Koll, Senior Scientist, IITM
A 2024 study in the Journal of Climate highlights that monsoon onset variability has increased by 15% over the past two decades, driven by global warming and atmospheric circulation shifts timesofindia.indiatimes.com. This trend may lead to more unpredictable rain events during June.
