[1] To investigate processes related to the interaction of topography and precipitation, a tropics-wide (±36 latitude) high resolution (0.1 ) ten year (1998–2007) rainfall climatology is presented from the Tropical Rainfall Measuring Mission (TRMM) precipitation radar (PR) using algorithm 2A25 version 6 near-surface rain. We observe a tight coupling between precipitation and topography with dis...

increased concentration of greenhouse gases is expected to alter the radiative balance of atmosphere, causing increases in temperature and changes in precipitation patterns and other climatic variables. these changes are associated with the changes in hydrological systems globally and at the basin scale. these changes include: precipitation patterns and extremes; the amount and generation of ri...

The accuracy of rainfall predictions in the EPA’s BASINS (Better Assessment Science Integrating Point and Nonpoint Sources) decision support tool is affected by the sparse meteorological data contained in BASINS. The objectives of this study were improvement of using the entropy theory to supplement the precipitation data are significant when the watershed’s meteorological station is either far...

qorveh – dehgolan aquifer is one of the ground water resources in kurdistan. increase in pumping of water has dropped water table level significantly. this study considers the relationship of fluctuations in precipitation, humidity and evaporation with ground water table level. after preparing the base map and the rainfall data accuracy, isohyetal map of basin was drown. based on isohyetal ma...

The current operational very short-term and shortterm quantitative precipitation forecast (QPF) at the Meteorological Service of Catalonia (SMC) is made by three different methodologies: Advection of the radar reflectivity field (ADV), Identification, tracking and forecasting of convective structures (CST) and numerical weather prediction (NWP) models using observational data assimilation (rada...

[1] Previous observational studies have identified three different types of diurnal precipitation variation over the conterminous U.S.: localized afternoon rainfall maxima over the Mississippi and Ohio valleys, propagating mesoscale convective systems (MCSs) from the Rocky Mountain region, and propagating MCSs over the Appalachian Mountains. This study focuses on the second type, which involves...

The purpose of this study is to describe a new algorithm based on a neural network approach (Passive microwave Neural network Precipitation Retrieval – PNPR) for precipitation rate estimation from AMSU/MHS observations, and to provide examples of its performance for specific case studies over the European/Mediterranean area. The algorithm optimally exploits the different characteristics of Adva...
