IMD scientist P.S. Biju finds Kerala monsoon often arriving May
India
Kerala's monsoon is now arriving earlier than it used to, often in May instead of June.
A study led by P.S. Biju, a senior scientist at IMD, found that after 2000, early monsoon starts have become much more common, pointing to a clear shift over time.
Kerala sees less rain, more extremes
Researchers say global warming is speeding up how quickly weather systems form and changing wind patterns, which brings the rains sooner.
At the same time, Kerala is seeing less southwest monsoon rainfall but more extreme downpours, especially in the north and near the Western Ghats, raising flood risks.
northern Kerala gets nearly double the rain compared with southern parts, so experts are calling for smarter local plans to handle these climate shifts.
