Indian downpours are driven more by uplift than extra humidity

For monsoon extremes over India, stronger upward motion supplies most of the extra moisture, not the Clausius–Clapeyron humidity increase alone.

What moisture-budget split is the paper’s focus?

Dynamic (vertical velocity) versus thermodynamic (humidity) contributions to Indian precipitation extremes.

Which two landmark floods are decomposed first?

Kerala 2018 and Uttarakhand 2013.

How anomalous was Kerala 2018 monsoon rainfall?

IMD reported 40% more rain than normal years from early June to August.

How extreme was the 13 June 2013 Uttarakhand burst?

More than 340 mm, almost 375% of JJAS climatic normal.

How many additional Indian extremes were composited?

26 events from 2005–2018 identified from IMD reports.

What fraction of vertical moisture transport is Dyn on average?

More than 90% across the 26 events.

Which reanalysis is used for the long climatology?

JRA-55, 1958–2018 (ERA-Interim 1981–2018 as a check).

How are model extremes defined for CMIP6?

Peak-over-threshold at the 95th percentile of JJAS days, 1950–2014.

Do CMIP6 models also emphasize Dyn?

Yes: recent CMIP6 simulations also show Dyn as important for Indian precipitation extremes.

What Clausius–Clapeyron rate is cited?

Water vapor content would increase at 7% per °C of surface warming.

What does Equation 4 identify as the main Dyn driver?

Changes in vertical velocity (omega).
