RISScientific Verification of Deterministic River Stage Forecasts
Publisher: American Meteorological Society
Abstract: One element of a complete verification system is the ability to determine why forecasts behave as they do. This paper describes and demonstrates an operationally feasible method for conducting this type of diagnostic ...
A Stochastic Precipitation Disaggregation Scheme for GCM Applications
Publisher: American Meteorological Society
Abstract: In the surface hydrologic pararmeterization of general circulation models (GCMs), it is commonly assumed that the precipitation processes are homogeneous over a GCM grid square and that the precipitation intensity is ...
LMODEL: A Satellite Precipitation Methodology Using Cloud Development Modeling. Part I: Algorithm Construction and Calibration
Publisher: American Meteorological Society
Abstract: The Lagrangian Model (LMODEL) is a new multisensor satellite rainfall monitoring methodology based on the use of a conceptual cloud-development model that is driven by geostationary satellite imagery and is locally updated ...
Evaluation of Official Western U.S. Seasonal Water Supply Outlooks, 1922–2002
Publisher: American Meteorological Society
Abstract: An analysis was conducted of almost 5000 operational seasonal streamflow forecast errors across the western United States. These forecasts are for 29 unregulated rivers with diversity in geography and climate. Deterministic ...
A Statistical Model for the Uncertainty Analysis of Satellite Precipitation Products
Publisher: American Meteorological Society
Abstract: arth-observing satellites provide a method to measure precipitation from space with good spatial and temporal coverage, but these estimates have a high degree of uncertainty associated with them. Understanding and quantifying ...
Assessment of the Spatial and Seasonal Variation of the Error–Intensity Relationship in Satellite-Based Precipitation Measurements Using an Adaptive Parametric Model
Publisher: American Meteorological Society
Abstract: tudies have been reported about the efficacy of satellites for measuring precipitation and about quantifying their errors. Based on these studies, the errors are associated with a number of factors, among them, intensity, ...
An Object-Oriented Approach to Investigate Impacts of Climate Oscillations on Precipitation: A Western United States Case Study
Publisher: American Meteorological Society
Abstract: his manuscript introduces a novel computational science approach for studying the impact of climate variability on precipitation. The approach uses an object-oriented connectivity algorithm that segments gridded near-global ...
An Artificial Neural Network Model to Reduce False Alarms in Satellite Precipitation Products Using MODIS and CloudSat Observations
Publisher: American Meteorological Society
Abstract: he Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard the NASA Earth Observing System (EOS) Aqua and Terra platform with 36 spectral bands provides valuable information about cloud microphysical ...
Hydrological Projections under CMIP5 and CMIP6: Sources and Magnitudes of Uncertainty
Publisher: American Meteorological Society
Verification of National Weather Service Ensemble Streamflow Predictions for Water Supply Forecasting in the Colorado River Basin
Publisher: American Meteorological Society
Abstract: The Ensemble Streamflow Prediction (ESP) system, developed by the National Weather Service (NWS), uses conceptual hydrologic models and historical data to generate a set, or ensemble, of possible streamflow scenarios ...
