Rainfall data are often collected at coarser spatial scales than required for input into hydrology and agricultural models. We therefore describe a spatio-temporal model which allows multiple imputation of rainfall at fine spatial resolutions, with a realistic dependence structure in both space and time and with the total rainfall at the coarse scale consistent with that observed. The method in...

Precise spatio-temporal measurements of rainfall during seasonal monsoons are critical for accurate hydrologic analyses in the tropical regions of Southeast Asia. The use of satellite precipitation data is technologically sound but requires downscaling to minimize inherent uncertainties. The uncertainties at a local climate regime that are essential to be resolved are rarely reported; consequen...

Recent analysis of spatial and temporal resolution of rainfall and the advent of small inexpensive rainfall radars has lead to increased use of radar estimated rainfall as input to hydrological models especially in urban areas. Detailed rainfall measurements have indicated a very high spatial variation of up to 100 % of a distance of less that 200 m over a 3 hour rainfall event [Jensen and Pede...

The usefulness of time-series simulation of daily rainfall for estimating large quantiles of the distribution of 10 d seasonal maximum rainfall is questioned. The emphasis is on rare 10 d events having a mean recurrence time much longer than the length of the historical record. Time-series simulation uses nonparametric resampling. With a theoretical example assuming no temporal dependence, it i...

accelerated soil erosion is an undesirable process that adversely affects water and soil resources. rainfall erosivity is an important factor in water erosion models. accordingly, the present study was conducted to estimate the rainfall erosivity throughout iran based on the latest available detailed rainfall data while considering its temporal and spatial variations. to accomplish this, th...

Projected changes in the future rainfall of the Sydney metropolitan region were investigated through fine scale (2km grid) dynamical downscaling from a single global climate model (GCM) simulation using the Weather Research and Forecasting (WRF) regional climate model. Projections of rainfall (20402059) were compared with a reanalysis-driven simulation for the period 1990-2009. There are projec...

spatio-temporal variability of throughfall (tf) has an important role on the biogeochemical processes,soil, watershed hydrology as well as the nutrient cycle in forests. spatial distribution and temporalstability of tf patterns by five individual persian oak trees (quercus brantii var. persica) in thezagros forests of western iran, ilam, was quantified. sixteen tf manual gauges were placed bene...

This paper presents an analysis of the interaction between the various variables associated with Rift Valley fever (RVF) such as the mosquito vector, available hosts and rainfall distribution. To that end, the varying zones potentially occupied by mosquitoes (ZPOM), rainfall events and pond dynamics, and the associated exposure of hosts to the RVF virus by Aedes vexans, were analyzed in the Bar...
