In this pattern the center of Iran is in the expansion of high pressure pattern with the epicenter 1016 millibars
and distance between Caspian Sea central parts to the east of Turkey is in scope of low pressure system of 1008 millibars
in which this state lets it move and it causes spreading of Iran central pressure to north of the country as well as air sustainability and lack of ascending currents on the earth surface which has been demonstrated in figure 3 (amount of pollution related to this pattern for 5 November 2006).
Sea Level Pressure = reported pressure at sea level in millibars
The phenomenon is when atmospheric pressure drops by 24 millibars
or in 24 hours.
The carbon layer evaporated on passing an electrical current through a graphite electrode within a vacuum chamber regulated to 10-5 millibars
. The specimens were covered with a gold microfilm by circulating a 20 amp current through a gold electrode within a vaporisation chamber (SCD 004 Balzers Sputter Coater) regulated to 0.1 millibars
The barometer measures pressure in 3 different units: inches of mercury (inHg) from 0.29 to 32.48 with a resolution of 0.01, millibars
(hPa) from 10.0 to 1100 with a resolution of 0.1 and 1 hPa, and millimeters of mercury (mmHg) from 7.5 to 825.0 with a resolution of 0.1 mmHg.
Average atmospheric pressure was 992.7 millibars
They also detected the hurricane's lowest minimum pressure had dropped to 958 millibars
, said Capt.
The barometer would plummet 35 millibars
in the next 24 hours, to a bestial 946 mb.
At pressures higher than some millibars
the molecular flux upon the moving mass is highly uniform, so the sum of every momentum discharged by the molecules on the sphere is null for any practical purpose.
A conventional water-ring vacuum pump draws 25 to 30 millibars
to remove residual moisture.
The new plasma curing system for automobile coatings has had in the pilot stage a microwave-excited process gas with a low pressure of only 0.06 millibars
To create wind direction maps for Africa [using National Centers for Environmental Prediction-National Center for Atmospheric Research (NCEP-NCAR) Reanalysis Project database and software (NOAA NCEP-NCAR 2006], we used mean monthly sea level pressure [SLP; in millibars
(mb)] and mean monthly geopotential values for three altitude levels: 1,000 mb (150 to ~ 200 m), 925 mb (700 to ~ 800 m), and 850 mb (~ 1,500 m) covering the whole African continent (NOAA NCEP-NCAR 2005).
