millibar

a cgs unit of atmospheric pressure equal to 10--3 bar, 100 newtons per square metre or 0.7500617 millimetre of mercury

millibar

[′mil·ə‚bär]
(mechanics)
A unit of pressure equal to one-thousandth of a bar. Abbreviated mb. Also known as vac.

millibar

A unit of measurement of pressure. In the standard atmosphere, air exerts a pressure of one bar at sea level. A bar is equal to 106 dynes per square centimeter. One bar = 1000 millibars = 750.8 mm Hg = 29.53 in Hg. The average sea level pressure is 1013.2 millibars or 29.92 in of mercury. Altimeter settings used to be given in millibars but now are more likely to be given in hPa (hectopascals). The values of millibars and hectopascals are the same.

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).
The eye of the storm is normally 150 km and barometric pressure of 960 millibars.
The samples were then hydrodynamically injected using an anodic depression of 80 millibars for 4 seconds (<1 nL, representing less than 1% of the total volume of the capillary tube).
Generally in the US, barometric pressure is reported in inches of mercury (in Hg) for weather reports, while scientists prefer to use millibars.
A pressure drop of 1130 millibars was measured, which validated several theories concerning the existence of those pressures inside a tornado.
The phenomenon is when atmospheric pressure drops by 24 millibars or in 24 hours.
13, 2004, Hurricane Charley had a low minimum pressure of 941 millibars before it slammed into southeastern Florida with 150 mph winds as a Category 4 storm.

A stagnation day is defined as one with sea-level geostrophic wind < 8 m/sec, 500 millibars (mb) wind < 13 m/sec, and no precipitation (Wang and Angell 1999), and although not directly related to pollutant emissions, air stagnation days can exacerbate the effects of existing air pollution.
From our present investigation it appears that the air pressure effect does not alter the accuracy of the classical G measurements performed at pressures higher than some millibars.
A conventional water-ring vacuum pump draws 25 to 30 millibars to remove residual moisture.
When a storm develops very quickly it is known as explosive cylogenesis - the pressure has to deepen by 24 millibars in 24 hours so this may not be as strong as that.
