The Presidents' Day Cyclone of 18–19 February 1979: Synoptic Overview and Analysis of the Subtropical Jet Streak Influencing the Pre-Cyclogenetic Period
TL;DR: In this article, a detailed analysis of the sub-subtropical jet streak revealed by an analysis of a Presidents' Day cyclone of February 18-19, 1979 is presented.
Journal ArticleDOI
Synergistic interactions between an upper-level jet streak and diabatic processes that influence the development of a low-level jet and a secondary coastal cyclone
TL;DR: In this article, a series of numerical simulations of the February 1979 Presidents Day cyclone is presented, including an adiabatic simulation that isolates the development of upper-level divergence along the axis of a subtropical jet streak and three other simulations that reveal the contributions of sensible and latent heat release in modifying lower-tropospheric wind fields and reducing the sea level pressure.
Journal ArticleDOI
On the Impact and Benefits of AMDAR Observations in Operational Forecasting—Part I: A Review of the Impact of Automated Aircraft Wind and Temperature Reports
TL;DR: In this article, the impact of WMO Aircraft Meteorological Data Relay (AMDAR) observations on operational numerical weather prediction (NWP) forecasts at both regional and global scales that support national and local weather forecast offices across the globe is reviewed.
Proceedings ArticleDOI
GIFTS - the precursor geostationary satellite component of the future Earth Observing System
William L. Smith,F. W. Harrison,D.E. Hinton,Henry E. Revercomb,Gail E. Bingham,Ralph A. Petersen,J.C. Dodge +6 more
TL;DR: The Geosynchronous Imaging Fourier Transform Spectrometer (GIFTS) combines advanced technologies to observe surface thermal properties and atmospheric weather and chemistry variables in four dimensions, an important step in implementing the NASA Earth Science Enterprise vision of a sensor web for future Earth observations.
Journal ArticleDOI
Comparisons of Satellite-Derived Atmospheric Motion Vectors, Rawinsondes, and NOAA Wind Profiler Observations
Kristopher M. Bedka,Christopher S. Velden,Ralph A. Petersen,Wayne F. Feltz,John R. Mecikalski +4 more
TL;DR: In this paper, the authors evaluate the accuracy and potential applications of a newly developed experimental mesoscale AMV product derived from Geostationary Operational Environmental Satellite (GOES) imagery and feature a significant increase in vector density throughout the troposphere and lower stratosphere over current NOAA/National Environmental Satellite, Data, and Information Service (NESDIS) processing.
