“…The SFs estimated by the binning approach are shown in Figure 2e,f. The SFs of OBS and PAST for P 99 are close to the C-C relation (7% per C) up to the temperature of 15 C but have a negative gradient at temperatures exceeding 15-20 C. The results are similar to the relationships noted for observations in Japan (Utsumi et al, 2011;Yamada et al, 2014;Fujibe, 2016). The P 99.9 has the same characteristics; however, the upper limit for which the SF follows the C-C relation is higher (18 C) than in the case of P 99 .…”

This study investigated the relationship between extreme precipitation and near-surface temperature (precipitation-temperature relation) from two different perspectives, the rate of change of precipitation with temperature and dynamic (i.e., effect of the change in atmospheric motion) and thermodynamic (i.e., effect of the change in atmospheric moisture content) aspects, using a 5-km dynamical downscaled hundreds-year data set for past climate condition (PAST; from 1951 to 2010) and future climate condition (FUTURE; 4 C warmer than the preindustrial condition). Initially, using the observation and the PAST and FUTURE data sets, it was found that the 99th and 99.9th percentile hourly precipitation for each temperature bin (P 99 and P 99.9 , respectively) paralleled the slope of the Clausius-Clapeyron (C-C) relation for a certain temperature range over the Tokachi River basin in Hokkaido, the northern island of Japan; however, both P 99 and P 99.9 decreased in the hightemperature range. Next, we examined the cause of the P 99 and P 99.9 differences between PAST and FUTURE for each temperature bin by classifying dynamic and thermodynamic factors. The result showed that the thermodynamic effect dominates the differences in P 99 and P 99.9 between PAST and FUTURE, which means that the thermodynamic effect is the main component of the precipitation-temperature relation. Similar analyses were applied to the whole river basin, including the mountainous area. The results showed that the differences in P 99 and P 99.9 between PAST and FUTURE are mainly due to the thermodynamic contribution, regardless of plain or mountain area. Using such large model data sets, we could make a robust assessment of the precipitation-temperature relation and the dynamic and thermodynamic contributions to precipitation changes. Moreover, using the 5-km resolution hundreds-year data set enabled us to quantify the spatial distribution of such precipitation characteristics over a thousands of square kilometer catchment.

“…This is important because rates of soil detachment have been shown to increase rapidly as the water ponding depth increases, related to lateral jetting away from drop impact locations. This effect causes a rapid increase in splash detachment as ponding depths increase up to about three drop diameters, equivalent to perhaps 10 mm or so for typical raindrop diameters (Gao et al, 2003). As was shown by Timmons et al (1971), drop impacts on ponding throw out splash droplets that are primarily made up of water from the ponding layer; surface tension limits the amount of water from an incident drop that becomes splash.…”

Abstract. Many land surface processes, including splash dislodgment and downslope transport of soil materials, are influenced strongly by short-lived peaks in rainfall intensity but are less well accounted for by longer-term average rates. Specifically, rainfall intensities reached over periods of 10–30 min appear to have more explanatory power than hourly or longer-period data. However, most analyses of rainfall, and particularly scenarios of possible future rainfall extremes under climate change, rely on hourly data. Using two Australian pluviograph records with 1 s resolution, one from an arid and one from a wet tropical climate, the nature of short-lived “intensity bursts” is analysed from the raw inter-tip times of the tipping bucket gauges. Hourly apparent rainfall intensities average just 1.43 mm h−1 at the wet tropical site and 2.12 mm h−1 at the arid site. At the wet tropical site, intensity bursts of extreme intensity occur frequently, those exceeding 30 mm h−1 occurring on average at intervals of <1 d and those of >60 mm h−1 occurring on average at intervals of <2 d. These bursts include falls of 13.2 mm in 4.4 min, the equivalent of 180 mm h−1, and 29 mm in 12.6 min, equivalent to 138 mm h−1. Intensity bursts at the arid site are much less frequent, those of 50–60 mm h−1 occurring at intervals of ∼1 month; moreover, the bursts have a much shorter duration. The aggregation of rainfall data to hourly level conceals the occurrence of many of these short-intensity bursts, which are potentially highly erosive. A short review examines some of the mechanisms through which intensity bursts affect infiltration, overland flow, and soil dislodgment. It is proposed that more attention to resolving these short-lived but important aspects of rainfall climatology is warranted, especially in light of possible changes in rainfall extremes under climate change.

“…The relationship between precipitation and temperature have been explored for several cases over some regions in Japan from multi-decadal observational data and/or climate simulations (e.g., Utsumi et al 2011;Yamada et al 2014;Fujibe 2016;Nayak et al 2018). Such studies examined the rainfall amounts as a daily basis.…”

The usefulness of Clausius-Clapeyron (CC) scaling in explaining extremely heavy precipitations is explored in the present-day climate and in pseudo-global-warming (PGW) conditions. This is analyzed by conducting regional-scale numerical simulations at 1-km grid resolution for two recent extreme rainfall events that occurred in Japan: the case in northern Kyushu during 5 -6 July 2017 and the case in Shikoku Island during 5 -8 July 2018. The Weather Research and Forecasting (WRF) model was used for the simulation, and the data samples were collected at each grid point individually for each hour over the two regions. We found that the frequency and intensity of extremely heavy precipitation associated with the two events are increased under PGW conditions. The extremely heavy precipitations (> 50 mm h −1 ) followed CC scaling for the temperatures up to 22°C in the present-day climate, while those under the PGW conditions followed CC-scaling up to 24°C. The peak intensity of the extremely heavy precipitations in the precipitation-temperature relationship is found as ~ 140 mm h −1 at 25°C in the present-day climate, while the same with PGW conditions is projected as ~ 160 mm h −1 at 27°C. The increasing rate of the extremely heavy precipitations in the present-climate condition is noticed as ~ 3 % °C −1 and that under the PGW conditions is anticipated as ~ 3.5 % °C −1 . The increase in peak precipitation intensity and the rate of precipitation increase against temperature in future warming climate are attributed to the decrease in temperature lapse rate and increase in atmospheric water vapor and convective available potential energy. To our knowledge, this is one of the first quantitative investigations of CC scaling of extremely heavy precipitations based on case studies.
