Multisite downscaling of daily precipitation with a stochastic weather generator
Stochastic models of daily precipitation are useful both for characterizing different precipitation climates and for stochastic simulation of these climates in conjunction with agricultural, hydrological, or other response models. A simple stochastic precipitation model is used to downscale— i.e. disaggregate from area-average to individual station—precipitation statistics for 6 groups of 5 U.S...
متن کاملSimulation of spatial dependence in daily rainfall using multisite generators
[1] A new approach for modeling the spatial dependence in rainfall occurrence is proposed. Being motivated by a technique for coupling Markov chains in interacting particle systems, it differs from existing approaches that only attempt to reproduce pairwise spatial correlations of rainfall occurrences or apply complex nonlinear models. It has the advantage of directly modeling the joint depende...
متن کاملGIS-based spatial precipitation estimation using next generation radar and raingauge data
Precipitation is one important input variable for land surface hydrologic and ecological models. Next Generation Radar (NEXRAD) can provide precipitation products that cover most of the conterminous United States at high resolution (approximately 4 km 4 km). There are two major issues concerning the application of NEXRAD data: 1) the lack of a NEXRAD geo-processing and geo-referring program and...
متن کاملTesting for Spatial Autocorrelation in Areal Data
Consider a linear model for a spatial system of n areal units, (1) , ~ (0,) Y X u u N V where both and V are unknown. The simplest procedure for specifying the covariance matrix, V , is to start by assuming that (2) 2 n V I , so that can be estimated by OLS. Given this estimate, one can then test to see whether there is sufficient spatial autocorrelation in the residuals to warran...
متن کاملEstimating IDF based on daily precipitation using temporal scale model
The intensity –duration –frequency (IDF) curves play most important role in watershed management, flood control and hydraulic design of structures. Conventional method for calculating the IDF curves needs hourly rainfall data in different durations which is not extensively available in many regions. Instead 24-hour precipitation statistics were measured in most rain-gauge stations. In this stud...
