The Wgne Assessment of Short-term Quantitative Precipitation Forecasts
APRIL 2003 AMERICAN METEOROLOGICAL SOCIETY | O f all the weather elements for which forecasts are provided to the public, rainfall is perhaps of the greatest interest. While most people simply want to know whether they will need an umbrella that day, there is growing demand from industry, agriculture, government, and many other sectors for more detailed rainfall predictions. Unfortunately, rain...
متن کاملThe Wgne Assessment of Short-term Quantitative Precipitation Forecasts
APRIL 2003 | C ategorical, or conditional, statistics quantify the skill in the prediction of the occurrence of rain, and are based on the familiar 2 × 2 (yes/no) contingency table. Given a set of matched rain forecasts and observations, the contingency table is a matrix giving the frequencies of predicted and observed rain occurrence and nonoccurrence. “Hits,” H, are correct predictions of rai...
متن کاملMultimodel SuperEnsemble technique for quantitative precipitation forecasts in Piemonte region
The Multimodel SuperEnsemble technique is a powerful post-processing method for the estimation of weather forecast parameters reducing direct model output errors. It has been applied to real time NWP, TRMM-SSM/I based multi-analysis, Seasonal Climate Forecasts and Hurricane Forecasts. The novelty of this approach lies in the methodology, which differs from ensemble analysis techniques used else...
متن کاملJ3.4 Calibration of Probabilistic Quantitative Precipitation Forecasts from the Rsm Ensemble Forecasts over Hydrologic Regions
Cool season precipitation plays an important role in freshwater supply over the Southwest United States, which is marked by heterogeneous topographic and hydrologic scenarios. More accurate precipitation prediction is highly desirable for both the public and hydrological model users. Numerous studies indicate that ensemble forecasting provides more skillful weather forecasts than a single deter...
متن کاملProbabilistic Forecasts of Precipitation Type
Precipitation-type forecasting is the determination of when and where particular types of precipitation (e.g., snow, rain, ice pellets, freezing rain) will occur during a forecast period. Although much is already known about the physical processes that determine the type of precipitation that reaches the ground, these forecasts are very challenging for most forecasters because of inadequate atm...
