Equatorial wave analysis from SABER and ECMWF temperatures
Equatorial planetary scale wave modes such as Kelvin waves or Rossby-gravity waves are excited by convective processes in the troposphere. In this paper an analysis for these and other equatorial wave modes is carried out with special focus on the stratosphere using temperature data from the SABER satellite instrument as well as ECMWF temperatures. Space-time spectra of symmetric and antisymmet...
متن کاملGlobal survey of concentric gravity waves in AIRSimages and ECMWF analysis
Concentric gravity waves (CGWs) are atmospheric phenomena with ring-shape perturbations originating in the troposphere. They can propagate up to the ionosphere and thermosphere and dynamically couple the lower and upper atmosphere. In this study we developed a novel ring detection algorithm to extract CGWs from the Atmosphere Infrared Sounder (AIRS) radiance data and the European Center for Med...
متن کاملThe seasonal cycle of Kelvin waves in the ECMWF analyses
Atmospheric dynamics in the tropical regions is dominated by unbalanced motions in response to convective processes, found to vary on many temporal scales from diurnal to inter-seasonal and inter-annual scales. The gravest wave excited by convection is the Kelvin wave and it is characteristics by eastward and upward propagation away from its convective source. As it propagates vertically, a pac...
متن کاملBending of Light by Gravity Waves
We describe the statistical properties of light rays propagating though a random sea of gravity waves and compare with the case for scalar metric perturbations from density inhomogeneities. For scalar fluctuations the deflection angle grows as the square-root of the path length D in the manner of a random walk, and the rms displacement of a ray from the unperturbed trajectory grows as D. For gr...
