An Analysis of Sea-Level Cyclone Errors in NMC's Nested Grid Model (NGM) During the 1987-88 Winter Season
(American Meteorological Society, 1990)A study of sea-level cyclone errors which occurred in 24- and 48-h forecasts of the National Meteorological Center's nested grid model (NGM) is performed for the 1987?88 winter season (1 December 1987?31 March 1988). All ... -
A Review of Numerical Forecast Guidance for Hurricane Hugo
(American Meteorological Society, 1990)Numerical forecast guidance for Hurricane Hugo from the National Meteorological Center is examined, as well as forecasts from the European Center for Medium Range Forecasting and the United Kingdom Meteorological Office. ... -
The Carolina Nocturnal Low-Level Jet: Synoptic Climatology and a Case Study
(American Meteorological Society, 1990)The nocturnal low-level jet (LLJ), a common Phenomenon in Many Part of the world, also occurs over the Carolinas in the eastern United States. The Carolina LLJ was studied using pilot balloon (PIBAL) observations taken ... -
Storm Following Climatology Of Precipitation Associated with Winter Cyclones Originating Over the Gulf of Mexico
(American Meteorological Society, 1990)A storm-following climatology was compiled for the precipitation distributions associated with winter cyclones that originate over the Gulf of Mexico and adjacent coastal region. The goal of this research is to investigate ... -
On Medium-Range Model Guidance and the 3–5 Day Extended Forecast
(American Meteorological Society, 1990)The medium-range forecast model (MRF) provides the basic guidance for the 3?5-day extended forecast issued by individual Weather Service Forecast Offices. The ability of the MRF to forecast shorter synoptic, subsynoptic, ... -

Operational Implications of the “Probability of Precipitation”
(American Meteorological Society, 1990)Since the probability of precipitation (PoP) appears in the forecasts of the National Weather Service (NWS), it is important that both the forecaster and user fully grasp the subtleties of the meaning of PoP. A brief review ... -
An Easy Method for Estimation of Q-Vectors from Weather Maps
(American Meteorological Society, 1990)It is shown how to estimate the directions and relative magnitudes of Q-vectors from a map of isobars and isotherms. The divergence of this vector field represents the forcing function in the quasi-geostrophic omega-equation. ... -
An Examination of Nested Grid Model Precipitation Forecasts in the Presence of Moderate-To-Strong Low-Level Southerly Inflow
(American Meteorological Society, 1990)The performance of the nested grid model (NGM) in predicting heavy rain is assessed for those cases in the cool season when moderato-to-strong low-level southerly inflow from the Gulf of Mexico is present. This study ... -
Trough-Merger Characteristics over North America
(American Meteorological Society, 1990)Split flow, defined by the presence or two separate westerly airstreams in the mid- and upper troposphere, is common in middle latitudes. Occasionally, individual troughs in the separate branches of the westerlies will ... -
Topographically Induced Convective Snowbands over the Baltic Sea and Their Precipitation Distribution
(American Meteorological Society, 1990)Convective snowbands over the Baltic Sea and its bays are examined to gain insight into snowband characteristics and precipitation distribution. A general description of the physical mechanisms responsible for snowband ... -
The Use of Satellite Imagery and Surface Pressure-Gradient Analysis Modified for Sloping Terrain to Analyze the Mesoscale Events Preceding the Severe Hailstorms of 2 August 1986
(American Meteorological Society, 1990)Conditions leading up to an outbreak of severe hailstorms in northeast Colorado are examined using satellite and surface data. A persistent mesoscale ridge of surface-high pressure, caused by outflow from a mesoscale- ... -
Operational Use of Profiler Data and Satellite Imagery to Evaluate the NMC Numerical Models in Predicting Heavy Snow
(American Meteorological Society, 1990)Near real-time wind profiler data from Stapleton International Airport at Denver, Colorado were used to confirm the existence of a midtropospheric closed low and vorticity maximum which were initially detected in satellite ... -
Improvement of Tornado Warnings by Doppler Radar Measurement of Mesocyclone Rotational Kinetic Energy
(American Meteorological Society, 1990)A significant improvement in the reliability and timeliness of tornado warnings can be achieved through quantitative measurement by Doppler radar of selected mesocyclone features. The mesocyclone, a midsize circulation ... -
SATMOD: An Interactive System Combining Satellite Images and Model Output Parameters
(American Meteorological Society, 1990)SATMOD is an interactive method which combines satellite images and several model output parameters. It is used at the Central Institute of Meteorology and Geodynamics in Vienna for satellite-synoptic research and for ... -
The National Hurricane Center—Past, Present, and Future
(American Meteorological Society, 1990)The National Hurricane Center (NHC) is one of three national centers operated by the National Weather Service (NWS). It has national and international responsibilities for the North Atlantic and eastern North Pacific ... -
