RISNorth American Rawinsonde Observations: Problems Concerns, and a Call to Action
Publisher: American Meteorological Society
Abstract: Meteorologists, like most scientists, often use observational data assuming the necessary steps have been taken to ensure that the quality of the data has been properly controlled. Experience developing an archive of ...
The Diurnal Variability of Florida Rainfall
Publisher: American Meteorological Society
Abstract: The diurnal variation of precipitation over the Florida peninsula is investigated on the basis of harmonic analysis of hourly rainfall data. Hourly data on the frequency of three categories of precipitation events for ...
Autumnal Rainfall Climatology of the Bahamas
Publisher: American Meteorological Society
Abstract: An autumnal rainfall climatology for the Bahamas is established on the basis of daily rainfall data. A southward shift of the rainfall maximum from September through November across the region is indicated. Frontal systems ...
Short-Range Numerical Weather Prediction Using Time-Lagged Ensembles
Publisher: American Meteorological Society
Abstract: A time-lagged ensemble forecast system is developed using a set of hourly initialized Rapid Update Cycle model deterministic forecasts. Both the ensemble-mean and probabilistic forecasts from this time-lagged ensemble ...
Accuracy of ACARS Wind and Temperature Observations Determined by Collocation
Publisher: American Meteorological Society
Abstract: A collocation study of meteorological reports from commercial aircraft relayed through the Aircraft Communications, Addressing, and Reporting System (ACARS) has been performed to estimate standard deviations of observation ...
The Use and Interpretation of Numerical Weather Prediction Model Output in Identifying Synoptic-Scale Environments Associated with Development of Mesoscale Convective Systems
Publisher: American Meteorological Society
Abstract: An experiment is reported in which derived diagnostic parameters computed from Limited-area Fine-Mesh (LFM) model gridpoint data were examined to determine subjectively whether their availability in real time would assist ...
Occurrence of Nonsurface Superadiabatic Lapse Rates within RAOB Data
Publisher: American Meteorological Society
Abstract: As part of creating an atmospheric database for research purposes, 73 497 radiosonde observation (RAOB) soundings from 1983 through 1987 were checked for nonsurface (at least 50 mb above the surface) superadiabatic lapse ...
The Value of Wind Profiler Data in U.S. Weather Forecasting
Publisher: American Meteorological Society
Abstract: An assessment of the value of data from the NOAA Profiler Network (NPN) on weather forecasting is presented. A series of experiments was conducted using the Rapid Update Cycle (RUC) model/assimilation system in which various ...
The Minneapolis Flash Flood: Meteorological Analysis and Operational Response
Publisher: American Meteorological Society
Abstract: The evolution of the synoptic- and meso-α-scale meteorological setting for the 23 July 1987 Minneapolis flash flood is described. Analyses of conventional upper-air data, including quasi-geostrophic processes, are employed ...
