Exalting in atmospheric tides as earthquake precursor
During February–March 1998, we observed a significant increase (6–8 dB) in the electric field of the CZE (f = 270 kHz, Czech Republic) broadcasting station at a site named AS and located in central Italy. On 13 March 1998 an earthquake (M = 5.2) occurred in Slovenia, starting a strong seismic crisis (M = 6.0 on 12 April, M = 5.1 on 6 May). The distances of the epicentres from the radio receiver...
متن کاملRadar wind profiler observations of solar semidiurnal atmospheric tides
Semidiurnal solar tides in the mid-latitude troposphere are investigated using harmonic analysis of 404 MHz radar profiler wind data obtained from a wide longitude zone in the U.S. The tides are apparent above a 1000-m-deep surface layer and increase in amplitude with height, attaining speeds of 0.5-0.7 rn/s at 5-7 km. Observed wind characteristics agree well with tidal characteristics obtained...
متن کاملAtmospheric Circulation and Tides of “51 Peg b-like” Planets
We examine the properties of the atmospheres of extrasolar giant planets at orbital distances smaller than 0.1AU from their stars. We show that these “51Peg b-like” planets are rapidly synchronized by tidal interactions, but that small departures from synchronous rotation can occur because of fluid-dynamical torques within these planets. Previous radiative-transfer and evolution models of such ...
متن کاملThe Theory of Bodily Tides . I .
The Gerstenkorn-MacDonald-Kaula theory of bodily tides assumes constancy of the geometric lag angle δ , while the Singer-Mignard theory asserts constancy of the time lag ∆t . Each of these two models is tacitly based on a particular law of the geometric lag’s dependence upon the main frequency χ of the tidal flexure. In the theory of Gerstenkorn (1955), MacDonald (1964), and Kaula (1964) δ ∼ χ0...
متن کاملObservations of atmospheric tides on Mars at the season and latitude of the Phoenix atmospheric entry
[1] We report on the atmospheric structure derived from atmospheric entry of NASA’s Phoenix Mars probe using Phoenix Atmospheric Structure Experiment (ASE) data complemented by Mars Cl imate Sounder (MCS) temperature‐pressure profiles. Oscillations in temperature, caused by thermal tides, have vertical wavelengths of tens of kilometres. Their amplitudes are much larger in individual profiles th...
