The effect of the barometric
pressure on sea level variability was removed by using the hydrostatic equation following the methodology of Gill (1982), and Salas-Monreal & Valle-Levinson (2008):
This belief suggests that the actual air pressure has little to do with the fish's desire to feed, but more accurately it seems likely that the weather conditions created by changes in barometric
pressure, such as clouds, rain and wind, have more effect on fishing than the barometric
My handheld required me to monitor the temperature, wind, and barometric
pressure and input it into the handheld.

Crappies may be quite susceptible to rapid changes in barometric
pressure, but that might not be the only reason we can't always find them where they're "supposed to be."
Hellickson found no direct correlations between deer activity and temperature, barometric
pressure, rainfall or any other weather factor he checked.
However, the inverse barometric
effect is seldom observed in the WT tiltmeters registrations (Chapter 5).
Deer hunters know falling barometric
pressure gets deer up and moving.
* Monitors and records temperature, relative humidity, and barometric
pressure over an Ethernet network or the Internet with no special software.
The service sends an e-mail alert to a subscriber to warn if the weather is likely to trigger a problem, such as changes in barometric
pressure or humidity, which can exacerbate arthritis.
These packs may contain an auxiliary or emergency 'chute' and a barometric
mechanical activating (auto-release) device.
pressure, humidity, fine particular matter, black carbon, sulfur dioxide and nitrogen content in the atmosphere were recorded during three 24-hour proceeding sessions.
