Evidence and Interpretation of a Spectral Gap in the Turbulent Atmospheric Temperature Spectra
Publisher: American Meteorological Society
Abstract: An analytical formulation of the turbulent potential energy spectrum in a stably stratified medium, valid in the inertia buoyancy subrange, is deduced in the framework of classical assumptions (no source, no sink, spectra ...
Linear Spectral Numerical Model for Internal Gravity Wave Propagation
Publisher: American Meteorological Society
Abstract: A three-dimensional linear spectral numerical model is proposed to simulate the propagation of internal gravity wave fluctuations in a stably stratified atmosphere. The model is developed to get first-order estimations of ...
Surface Pressure Fluctuations Produced by the Total Solar Eclipse of 1 August 2008
Publisher: American Meteorological Society
Abstract: uring a solar eclipse, the moon?s shadow progressively occults a part of Earth from the solar flux. This induces a cooling in the atmospheric layers that usually absorb the solar radiation. Since the eclipse shadow travels ...
Validation of Winds Measured by MU Radar with GPS Radiosondes during the MUTSI Campaign
Publisher: American Meteorological Society
Abstract: For many years, mesosphere?stratosphere?troposphere (MST) radar techniques have been used for studying the structure and dynamics of the lower and middle atmosphere. In particular, these instruments are unique tools for ...
Strong Mixing Events Observed near the Tropopause with the MU Radar and High-Resolution Balloon Techniques
Publisher: American Meteorological Society
Abstract: In the present paper, strong isotropic radar echo enhancements are shown that are related to the existence of nearly statically neutralized layers (40?120 m thick) observed with high-resolution (10 cm) temperature measurements ...
