Dust Tracking Using Composite Visible/IR Images: A Case Study
(American Meteorological Society, 1989)Visible and infrared (IR) images from the National Oceanic and Atmospheric Administration's (NOAA's) Advanced Very High Resolution Radiometer are composited to improve the depiction of airborne dust over coastlines. On IR ... -
The Effect of Snow Cover on the Regional Analysis and Forecast System (RAFS) Low-Level Forecasts
(American Meteorological Society, 1989)The response of the Regional Analysis and Forecast System (RAFS) low-level forecast fields to the geographical distribution of snow cover is discussed. The errors produced by an improper specification of this field in the ... -
Systematic Surface Cyclone Errors in NMC's Nested Grid Model November 1988–January 1989
(American Meteorological Society, 1989)Preliminary results from a study examining the performance of the nested grid model (NGM) in predicting cyclones covering a period from 13 November 1988 to 31 Match 1989 reveal that the NGM tends to overdevelop surface ... -
Performance of the ECMWF Model in Predicting the Movement of Typhoon Wayne (1986)
(American Meteorological Society, 1989)Typhoon Wayne (1986) was one of the most unusual typhoons over recorded over the western North Pacific. During its life span of over 20 days, it made four directional reversals, all of which took place over the northern ... -
Retrieving Horizontal Temperature Gradients and Advections from Single-Station Wind Profiler Observations
(American Meteorological Society, 1989)Vertical wind shears measured by the Plattevilie, Colorado wind profiler were used in conjunction with the geostrophic thermal wind equation to retrieve the horizontal thermal gradients and associated advections for a case ... -
RAINSAT. A One Year Evaluation of a Bispectral Method for the Analysis and Short-Range Forecasting of Precipitation Areas
(American Meteorological Society, 1989)RAINSAT uses under data to calibrate GOES visible and infra data in terms of probability of rain. It produces probability of rain maps and 3 h forecast probability of rain maps by extrapolation. An evaluation is made of ... -
The Use of Perfect Prog Forecasts to Improve Model Output Statistics Forecasts of Precipitation Probability
(American Meteorological Society, 1989)A method of improving the accuracy of model output statistics (MOS) probability of precipitation (POP) forecasts was investigated. The method uses a perfect prog (PP) forecast as a potential predictor in a MOS equation. ... -
Heavy Rains and Flooding in Montana: A Case for Operational Use of Symmetric Instability Diagnosis
(American Meteorological Society, 1989)A strongly developing cyclone east of the Rockies moved northward along the Montana/North Dakota border between 24?26 September 1986 and deposited over 1 in. of rain throughout much of eastern Montana. Included in this ... -
Some Characteristics of the Limited-Area Fine-Mesh (LFM) Model Quantitative Precipitation Forecasts (QPF) during the 1982 and 1983 Warm Seasons
(American Meteorological Society, 1989)The skill of the limited-area fine-mesh (LFM) model in making 24-h areal quantitative precipitation forecasts (QPF) of ? 0.5 in. (12.7 mm) is evaluated and analyzed for two warm seasons; 1982 and 1983. Differences in skill ... -
Skill in Prediction of Explosive Cyclogenesis over the Western North Atlantic Ocean, 1987/88: A Forecast Checklist and NMC Dynamical Models
(American Meteorological Society, 1989)Analyses and predictions of explosive cyclogenesis over the western North Atlantic Ocean during the 1987/88 cold season were compared. The analyses were the manual and automated series produced at the National Meteorological ... -
Cyclogenesis in Cold Air Masses
(American Meteorological Society, 1989)The small-scale and rapid development of polar lows over relatively data-sparse areas results in a special forecast challenge for the operational forecasting community. This paper constitutes a review of recent advances ... -
Tornadoes in France
(American Meteorological Society, 1989)In the period 1680?1988, 107 significant tornadoes in the Fujita scale categories F2?F5 have occurred in France. These include 49 such events in the historical period 1680?1959, and 58 events in the modem period 1960?1988. ... -
Forecasting and Verifying in a Field Research Project: DOPLIGHT '87
(American Meteorological Society, 1989)Verification of forecasts during research field experiments is discussed and exemplified using the DOPLIGHT '87 experiment. We stress the importance of forecast verification if forecasting is to be a serious component of ... -
