A methodology is described to construct fully parametric rainfall retrieval algorithms for a variety of passive microwave sensors that exist today and are planned for the future. The Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) is used to retrieve nonraining geophysical parameters. The method then blends these background geophysical parameters with three-dimensional precipi...

The authors analyze information from rain gauges, geostationary infrared satellites, and low earth orbiting radar in order to describe and characterize the submesoscale ( 75 km) spatial pattern and temporal dynamics of rainfall in a 50 km 75 km study area located in Sonora, Mexico, in the periphery of the North American monsoon system core region. The temporal domain spans from 1 July to 31 Aug...

This paper describes the theoretical basis and conceptual design of a dual-frequency radar and microwave link (radar/link) system capable of measuring simultaneously forward and backscatter from rainfall. The forward and backscattering radar/link system will enable small-scale rain studies essential in understanding the rainfall process, and make significant contributions to the investigation o...

A spatial characterization of mid-latitude mesoscale rain fields from C-band radar measurements is performed by means of a systematic analysis and modelling of convective raincell shapes. To this aim a large rainfall dataset, derived from an operational C-band dualpolarized radar, has been continuously collected from 1996 to 1999. The radar-derived rain fields consist of 1558 grids of 256×256 k...

Important characteristics of an appropriate river basin model, intended to study the effect of climate change on basin response, are the spatial and temporal resolution of the model and the rainfall input. The effects of input and model resolution on extreme discharge of a large river basin are assessed to give some indication on appropriate resolutions. A simple stochastic rainfall model and a...

Using the Morlet continuous wavelet transform on data over the period 1871-1990, it is found that the global wavelet cross spectra between two solar activity indices and seven major Indian monsoon rainfall time series show significant power around the period of the 11 year solar cycle, passing the χ test of significance proposed by Torrence and Compo (1998) at levels exceeding 95% in 10 out of ...

A rainfall–runoff (RR) model considering the spatial variation of rainfall, soil infiltration capability and soil storage capacity over a catchment and based on probability distribution functions, is used for rainfall–runoff modelling. The model combines infiltration excess (Horton) and saturation excess (Dunne) mechanisms. Moreover, it is applied to a data sparse catchment. Model parameters of...

Digital elevation models (DEM) of the four catchments were imported into E2, and subcatchment boundaries were delineated. Rainfall surfaces derived from spatial interpolation of ground-based observation data onto a 5 km x 5 km grid was pre-processed to provide a weighted average daily rainfall for each sub-catchment. Data of long term mean monthly potential evapotranspiration (PET) was also use...
