Decreasing precipitation extremes at higher temperatures in tropical regions
It has been often accepted that rising troposphere temperatures will lead to higher precipitation intensities. This argument has origins in the Clausius-Clapeyron (C-C) relation, which indicates an increase in atmospheric moisture storage capacity of approximately 7% Kelvin-1. However, recent investigations carried out in mid-latitude regions indicate that changes in precipitation intensity do not necessarily follow the C-C relation. This study aimed to evaluate the connection between precipitation extremes and temperature in tropical regions, using measured data obtained at low latitude ranges over Brazil. The results indicate that the C-C relation is unlikely to explain the relation between precipitation extremes and temperatures in tropical regions. Moreover, this study suggests that, in tropical regions, higher temperatures may reduce the magnitude of extreme precipitation events, independent of the season of the year.
