Barometric Pressure Variations Associated with Eastern Pacific Tropical Instability Waves*
Barometric pressure, surface temperature, and wind time series in the eastern equatorial Pacific are analyzed to determine if oceanic tropical instability wave (TIW) sea surface temperature variations cause barometric pressure gradients large enough to influence the atmospheric boundary layer. During the study period from April 2001 to September 2002, 11 TIWs propagated westward past 110!W, cau...
متن کاملbarometric pressure cycles
Barometric pressure changes can induce airflow in an open borehole or well screened in the vadose zone, thereby ventilating the soil surrounding the borehole. This paper presents an analytic model of the induced airflow and compares the predictions of the model with experimental measurements. This model may be useful for the design of passive soil vapor extraction as applied to the remediation ...
متن کاملLunar and Solar Barometric Tides in Australia
The lunar semidiurnal barometric tide Lz and the solar 2 4 , 12-, and &hr. oscillations of the surface pressure have been determined for 10 stations in Australia and on adjacent islands. At Rabaul and Moresby L2 is considerably smaller than elsewhere in these latitudes. The characteristic annual variation of the phase-late high tide during the D season-is found a t most Australian stations. But...
متن کاملBarometric pumping of a fractured porous medium
Barometric pumping plays a crucial role in the release of trace gases from fractured porous media to the atmosphere, and it requires a rigorous and complete modeling in order to go beyond the approximate schemes available in the literature. Therefore, a coupled set of convection and convection-diffusion equations for a slightly compressible fluid in unsteady conditions should be solved. The num...
متن کاملA Stochastic Approach to Noise Modeling for Barometric Altimeters
The question whether barometric altimeters can be applied to accurately track human motions is still debated, since their measurement performance are rather poor due to either coarse resolution or drifting behavior problems. As a step toward accurate short-time tracking of changes in height (up to few minutes), we develop a stochastic model that attempts to capture some statistical properties o...
