Consistent Large‐Scale Response of Hourly Extreme Precipitation to Temperature Variation Over Land

Hourly precipitation extremes can intensify with temperature at higher rates than expected from thermodynamic increases explained by the Clausius-Clapeyron (CC) relationship (∼6.5%/K), but local scaling surface air is highly variable. Here we use daily dew point temperature, a direct proxy of absolute humidity, to estimate at-gauge across six macro-regions for global data set over 7,000 hourly gauges. We find CC 2 × more 60% gauges, peaking in tropics median rate ∼1.5CC. Moreover, regional show surprisingly universal behavior around CC, Europe. Importantly impacts, persistently extreme precipitation. Our results indicate greater consistency previous work, usually or above positive (sub)tropics. This demonstrates relevance DPT understanding future changes.
