Cluster Analysis for Verification of Precipitation Fields
Publisher: American Meteorological Society
Abstract: A statistical method referred to as cluster analysis is employed to identify features in forecast and observation fields. These features qualify as natural candidates for events or objects in terms of which verification ...
Verification with Variograms
Publisher: American Meteorological Society
Abstract: The verification of a gridded forecast field, for example, one produced by numerical weather prediction (NWP) models, cannot be performed on a gridpoint-by-gridpoint basis; that type of approach would ignore the spatial ...
Cluster Analysis for Object-Oriented Verification of Fields: A Variation
Publisher: American Meteorological Society
Abstract: In a recent paper, a statistical method referred to as cluster analysis was employed to identify clusters in forecast and observed fields. Further criteria were also proposed for matching the identified clusters in one ...
Optical Flow for Verification
Publisher: American Meteorological Society
Abstract: Modern numerical weather prediction (NWP) models produce forecasts that are gridded spatial fields. Digital images can also be viewed as gridded spatial fields, and as such, techniques from image analysis can be employed ...
MOS, Perfect Prog, and Reanalysis
Publisher: American Meteorological Society
Abstract: Statistical postprocessing methods have been successful in correcting many defects inherent in numerical weather prediction model forecasts. Among them, model output statistics (MOS) and perfect prog have been most common, ...
An Object-Oriented Verification of Three NWP Model Formulations via Cluster Analysis: An Objective and a Subjective Analysis
Publisher: American Meteorological Society
Abstract: Recently, an object-oriented verification scheme was developed for assessing errors in forecasts of spatial fields. The main goal of the scheme was to allow the automatic and objective evaluation of a large number of ...
Model Tuning with Canonical Correlation Analysis
Publisher: American Meteorological Society
Abstract: nowledge of the relationship between model parameters and forecast quantities is useful because it can aid in setting the values of the former for the purpose of having a desired effect on the latter. Here it is proposed ...
