Scaling of precipitation extremes with temperature in China’s mainland: Evaluation of satellite precipitation data

• Four types of temperature sampling are compared for scaling precipitation extremes. The peak structure remains in the extreme precipitation‐temperature relationship. IMERG’s daily rate is close to observation. Against expectations, 30-min precipitations much smaller. This study explores sensitivity (termed factor, SF) and 30-minute extremes with several variables, i.e., within-day surface air (SAT) dew point (DPT), antecedent SAT DPT (corresponding temperatures one day before a event, denoted as SAT-C DPT-C) across China’s mainland. To this end, we used observed meteorological data from CN05.1 dataset Integrated Multisatellite Retrievals Global Precipitation Measurement (IMERG). Our results reveal mix positive negative SFs climatic zones, peak-like structures developing at higher (between 17 24 °C). Although almost all turn when SAT-C, DPT, DPT-C used, over some parts each climate zone, especially tropical regions. A comparison between full range reveals that single not valid entire range. Moreover, calculated based on (for four temperatures) follow better Clausius-Clapeyron (∼7%/°C) than except region. Daily IMERG mostly comparable results, discrepancies mainly plateau climates (roughly 25% area). However, do rise expected (even decrease country) increasing temperatures, contrary common observations reported previous studies. It suggests another needed scale, least
