A Pattern Recognition Technique for Distinguishing Surface and Cloud Types in the Polar Regions
Publisher: American Meteorological Society
Abstract: Measurement of polar cloud cover is important because of its strong radiative influence on the energy balance of the snow and ice surface. Conventional satellite cloud detection schemes often fail in the polar regions ...
Ability of a Poor Man's Ensemble to Predict the Probability and Distribution of Precipitation
Publisher: American Meteorological Society
Abstract: A poor man's ensemble is a set of independent numerical weather prediction (NWP) model forecasts from several operational centers. Because it samples uncertainties in both the initial conditions and model formulation through ...
Analysis of Polar Clouds from Satellite Imagery Using Pattern Recognition and a Statistical Cloud Analysis Scheme
Publisher: American Meteorological Society
Abstract: The analysis of cloud cover in the polar regions from satellite data is more difficult than at other latitudes because the visible and thermal contrasts between the cloud cover and the underlying surface are frequently ...
Neighborhood Verification: A Strategy for Rewarding Close Forecasts
Publisher: American Meteorological Society
Abstract: High-resolution forecasts may be quite useful even when they do not match the observations exactly. Neighborhood verification is a strategy for evaluating the ?closeness? of the forecast to the observations within space?time ...
Performance of Hourly Operational Consensus Forecasts (OCFs) in the Australian Region
Publisher: American Meteorological Society
Abstract: This paper presents an extension of the operational consensus forecast (OCF) method, which performs a statistical correction of model output at sites followed by weighted average consensus on a daily basis. Numerical weather ...

Gridded Operational Consensus Forecasts of 2-m Temperature over Australia
Publisher: American Meteorological Society
Abstract: his paper describes an extension of an operational consensus forecasting (OCF) scheme from site forecasts to gridded forecasts. OCF is a multimodel consensus scheme including bias correction and weighting. Bias correction ...
Performance of Satellite Rainfall Estimation Algorithms during TOGA COARE
Publisher: American Meteorological Society
Abstract: Over 50 satellite rainfall algorithms were evaluated for a 5° square region in the equatorial western Pacific Ocean during TOGA COARE, November 1992?February 1993. These satellite algorithms used GMS VIS/IR, AVHRR, and ...
Incorporating Satellite Observations of “No Rain” in an Australian Daily Rainfall Analysis
Publisher: American Meteorological Society
Abstract: Geostationary satellite observations can be used to distinguish potential rain-bearing clouds from nonraining areas, thereby providing surrogate observations of ?no rain? over large areas. The advantages of including such ...
Observations of Record Cold Cloud-Top Temperatures in Tropical Cyclone Hilda (1990)
Publisher: American Meteorological Society
Abstract: A detailed analysis is made of the development of a region of cold cloud-top temperatures in Tropical Cyclone Hilda (1990) in the Coral Sea off eastern Australia. Observed temperatures of approximately 173 K (?100°C) from ...
