text: 'Expected changes to future extreme precipitation remain a key uncertainty
associated with anthropogenic climate change. Extreme precipitation has been proposed
to scale with the precipitable water content in the atmosphere. Assuming constant
relative humidity, this implies an increase of precipitation extremes at a rate
of about 7% °C−1 globally as indicated by the Clausius‐Clapeyron relationship.
Increases faster and slower than Clausius‐Clapeyron have also been reported. In
this work, we examine the scaling between precipitation extremes and temperature
in the present climate using simulations and measurements from surface weather
stations collected in the frame of the HyMeX and MED‐CORDEX programs in Southern
France. Of particular interest are departures from the Clausius‐Clapeyron thermodynamic
expectation, their spatial and temporal distribution, and their origin. Looking
at the scaling of precipitation extreme with temperature, two regimes emerge which
form a hook shape: one at low temperatures (cooler than around 15°C) with rates
of increase close to the Clausius‐Clapeyron rate and one at high temperatures
(warmer than about 15°C) with sub‐Clausius‐Clapeyron rates and most often negative
rates. On average, the region of focus does not seem to exhibit super Clausius‐Clapeyron
behavior except at some stations, in contrast to earlier studies. Many factors
can contribute to departure from Clausius‐Clapeyron scaling: time and spatial
averaging, choice of scaling temperature (surface versus condensation level),
and precipitation efficiency and vertical velocity in updrafts that are not necessarily
constant with temperature. But most importantly, the dynamical contribution of
orography to precipitation in the fall over this area during the so‐called “Cevenoles”
events, explains the hook shape of the scaling of precipitation extremes.'
