The GPS meteorology (GPS/MET) experiment, led by the Universities Corporation for Atmospheric Research (UCAR), consists of a GPS receiver aboard a low earth orbit (LEO) satellite which was launched on 3 April 1995. During a radio occultation the LEO satellite rises or sets relative to one of the 24 GPS satellites at the Earth's horizon. Thereby the atmospheric layers are successively sounded by...

MARCH 2005 AMERICAN METEOROLOGICAL SOCIETY | O ver the past half century, Jim Angell has made pioneering contributions to meteorology, especially to our understanding of climate variability, stratospheric processes, and the ozone layer. On 4 November 2003, many colleagues and friends gathered at the National Oceanic and Atmospheric Administration (NOAA) Science Center in Silver Spring, Maryland...

The applied meteorology degree program at Embry-Riddle Aeronautical University’s (ERAU) Daytona Beach campus has been in existence since 2000. At the end of the fall 2007 semester, there were 106 undergraduate majors and 35 minors in the program. Forecasting Techniques is a three-credit course. It is the second in a three-course sequence that begins with a five-credit Weather Analysis course (e...

India Meteorological Department has entered into a new era in exploring the atmosphere with the induction of state-of-the-art Doppler weather radar technology in its cyclone detection radar network. This article describes the salient features of the Doppler weather radar installed at Chennai. Use of Doppler technique combined with digital technology makes it possible to measure directly the win...

The derivation of the quasi-geostrophic potential vorticity equation of mathematical meteorology is usually done using fairly sophisticated techniques of perturbation theory, but stops short of deriving self-consistently the stratification parameter of the mean atmospheric state. In this note we suggest how this should be done within the confines of the theory, and as a consequence we raise the...

By animating enhanced coarse surface pressure observations of 12 1985 Preliminary Regional Experiment for Storm-Scale Operational Research Meteorology (PRE-STORM) mesoscale convective systems (MCSs) the authors exposed 92 transitory highs and lows living within virtually all of the systems’ mesohighs and wake lows. A quasi-Lagrangian (feature following, not material following) analysis of the p...

The U.S. IVeather Bureau has been experimenting with a radar operating on the Doppler principle t o dc%ermine whether apparatus of this type would detect and uniquely identify tornadoes. The principles of Doppler radar as applied to meteorology and results of recent experiment,s with equipment of this type are discussed. Calculations of anomalous wind speeds of 206 m.p.h. in a funnel cloud and ...
