Extreme rainfall intensities are physically bounded by the Clausius-Clapeyron relation, which governs the moisture-holding capacity of the atmosphere at a given temperature.

The analysis

The retrieved papers consistently demonstrate that extreme sub-daily rainfall intensities scale according to the Clausius-Clapeyron relationship, establishing a thermodynamic limit tied to atmospheric water-holding capacity.

Paper 0 shows that extreme sub-hourly precipitation intensities scale asymptotically with the Clausius-Clapeyron relation, reflecting the physical water-holding capacity bound of a warmer atmosphere.
