Cause of Low Barometric Pressure

barometric 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 ...

AN1326, Barometric Pressure Measurement Using Semiconductor Pressure Sensors

The most recent advances in silicon micromachining technology have given rise to a variety of low-cost pressure sensor applications and solutions. Certain applications had previously been hindered by the high-cost, large size, and overall reliability limitations of electromechanical pressure sensing devices. Furthermore, the integration of on-chip temperature compensation and calibration has al...

Geosat Observations of Sea Level Response to Barometric Pressure Forcing

Altimeter and sea level pressure data from the Geosat mission are analyzed for evidence of inverted barometer response of sea level to atmospheric pressure forcing. Estimates of the inverted barometer coeecient are given for a variety of geographic regions and time scales using various orbit error removal strategies. There is some sensitivity to the orbit error removal method, but the estimated...

Influence of barometric pressure on interleukin-1b secretion

Becker, William J., and Joseph G. Cannon. Influence of barometric pressure on interleukin-1b secretion. Am J Physiol Regulatory Integrative Comp Physiol 280: R1897–R1901, 2001.— Monocytes and macrophages are activated by various environmental challenges, including microorganisms, radiation, and pollutants. These cells release cytokines, such as interleukin (IL)-1b, that mediate physiological ad...
