Statistical downscaling of precipitation
Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Global Circulation Models (GCMs) are a major tool used for future projections of climate change using different emission scenarios. However, for assessing the hydrological impacts of climate change at the watershed and the regional scale, ...
متن کاملDownscaling of seasonal precipitation for crop simulation
A non-homogeneous hidden Markov model (NHMM) is used to make stochastic simulations of March–August daily rainfall at 10 stations over the southeastern United States, 1923–98. Station-average observed daily rainfall is prescribed as an input to the NHMM, which is then used to disaggregate the rainfall in space. These rainfall simulations are then used as inputs to a CERES crop model for maize. ...
متن کاملA Comparison of Different Regression Algorithms for Downscaling Monthly Satellite-Based Precipitation over North China
Environmental monitoring of Earth from space has provided invaluable information for understanding land–atmosphere water and energy exchanges. However, the use of satellite-based precipitation observations in hydrologic and environmental applications is often limited by their coarse spatial resolutions. In this study, we propose a downscaling approach based on precipitation–land surface charact...
متن کاملComparison of physical and statistical methods for estimating probable maximum precipitation in southwestern basins of Iran
The probable maximum precipitation (PMP) is the greatest depth of precipitation for a given duration that is physically possible over a given size storm area at a particular geographical location at a certain time of the year. In this study a physically based method was compared with a statistical procedure to calculate PMP in the southwest arid regions of Iran. In order to estimate PMP using a...
متن کاملP1.23 Downscaling and Projection of the Wintertime Extreme Daily Precipitation over North America by Large-scale Atmospheric Circulation
The influence of large scale circulation, represented by the first three rotated EOFs and their associated PCs of wintertime mean sea level pressure, on winter maximum daily precipitation over the North America during 1948-1998 has been investigated. The observed relationship between the circulation and the extreme precipitation is then used to derive projected changes in extreme precipitation ...
