Probabilistic forecast of daily areal precipitation focusing on extreme events
A dynamical downscaling scheme is usually used to provide a short range flood forecasting system with highresolved precipitation fields. Unfortunately, a single forecast of this scheme has a high uncertainty concerning intensity and location especially during extreme events. Alternatively, statistical downscaling techniques like the analogue method can be used which can supply a probabilistic f...
متن کاملEstimating Historical California Precipitation Phase Trends Using Gridded Precipitation, Precipitation Phase, and Elevation Data
Climate change projections for California indicate reduction in the percentage of precipitation that falls as snow, and increase in the percentage that falls as rain, due to warmer temperatures in the future. Previous work has shown overall decreases in rainfall / snowfall ratios for the western US over the last 60 years. Of interest in this study is the quantification of snow/rain ratios for s...
متن کاملDownscaling Extremes: a Comparison of Extreme Value Distributions in Point-source and Gridded Precipitation Data By
There is substantial empirical and climatological evidence that precipitation extremes have become more extreme during the twentieth century, and that this trend is likely to continue as global warming becomes more intense. However, understanding these issues is limited by a fundamental issue of spatial scaling: most evidence of past trends comes from rain gauge data, whereas trends into the fu...
متن کاملDevelopment and analysis of a 50-year high-resolution daily gridded precipitation dataset over Spain (Spain02)
In this paper we present a new publicly available high-resolution daily precipitation gridded dataset developed for peninsular Spain and the Balearic islands using 2756 quality-controlled stations (this dataset is referred to as Spain02). The grid has a regular 0.2 (aprox. 20km) horizontal resolution and spans the period from 1950 to 2003. Different interpolation methods were tested using a cro...
متن کاملConsiderations for the use of radar-derived precipitation estimates in determining return intervals for extreme areal precipitation amounts
To explore the feasibility of radar-based extreme precipitation climatologies, prototype radar areal reduction factor (ARF) curves are developed and compared to those based on traditional rain gauge networks. For both the radar and gauge data, increasing the spatial density of observations has little influence on the ARF relationship. However, independently, considerable differences between rad...
