It means that in the area of the high pressure there weight of air above you is heavier than outside the high pressure area. This could be cause by the air being denser (ie could air) or by the atmosphere being locally, physically thicker.

What does a high millibar measurement in a high pressure area mean?
cause people know this off the top of their head. no.
Force put on a given area by the weight of the air above it is called?
We measure this force using a barometer. Because there are different kinds of barometers, there are also different unit of measurement for this force. A mercury barometer measures in inches of mercury (in Hg), the english (non-metric) system uses pounds per square inch (PSI), and the pascal (Pa) is the standard in the metric system. In weather terminology, the bar and millibar indicate pressure readings.
Why are tornadoes so powerful?
Tornadoes are very powerful because they have very low pressure at their centers. The large pressure drop over a short distance produces very fast winds. A tornado originates from a larger but less intense circulation called a mesocyclone which is embedded in a strong thunderstorm called a supercell. Other forces within the storm focus the lower portion of the mesocyclone into a smaller area, increasing both the pressure drop and the winds speed, so that instead of a 5 millibar pressure drop occurring over a distance of 2-6 miles a 50 millibar or greater pressure drop occurs over a distance usually less than 1/4 mile.
What particles of gas in the air pressing on earths surface create a force called what?
The name of the force of air that exerts on the Earth surface is called pressure and it is defined as F/A which means force per area. Pressure is the amount of force the molecules in the atmosphere applies in a given area. You can think of it as a air column, the more air molecules in a column, the more force forced applied to the surface. The less air in the column, the less pressure at the surface. Pressure is measured in pascals which is the standard SI unit for pressure but in meteorology we used hectopascal which is often converted to millibars. 1 millibar is equal to 1 hectopascal. 100 pascal is equal to 1 hectopascal or 1 millibar. Why do we use millibar? Because the pressure exerted by the atmosphere is large, using pascals would be too large of numerical values. 1013 millibars is approximate sea level pressure and that would be 101300 pascal, and no meteorologist would want to write out large values on weather maps as that would take up too much space. As for the type of gas that exerts on the surface is a mixture of oxygen, nitrogen, tiny fraction of argon and water vapor. Nitrogen and oxygen are the biggest contributors to atmospheric pressure.
When coastal land is warmer than the nearby water what type of breeze forms?
Along Coastlines, warmer air relates to lower air pressure, thus air flows from the higher-pressure, cooler setting into the area of lower air pressure. If the land is warmer, it has lower air pressure. Air over the sea would therefore be cooler and thus have higher atmospheric pressure, and the air will naturally from from the higher pressure (in this case, from over the ocean) to the lower pressure (over the warmer land).So you get a wind from the water onto the land, or a sea breeze.
What does the higher Millibar measurement in a higher pressure area mean?
It means that in the area of the high pressure there weight of air above you is heavier than outside the high pressure area. This could be cause by the air being denser (ie could air) or by the atmosphere being locally, physically thicker.

What does the higher millibar measurement in a high-pressure area mean?
It means that in the area of the high pressure there weight of air above you is heavier than outside the high pressure area. This could be cause by the air being denser (ie could air) or by the atmosphere being locally, physically thicker.

What is measured by millibars?
atmospheric pressure in measured in millibars
What is the unit of measure for atmospheric pressure most commonly found on weather maps?
Pressure is shown with white curvy lines. The closer the lines are to each other in a certain area, the higher the pressure is. The farter apart they are, the lower the pressure is in that area.
Measurement of pressure is determined by?
Pressure is directly proportional to force and inversely proportional to Area. If force is more, pressure is more and if area is more, pressure will be less.
How to calculate tonnage in hydraulic press machine?
Hydraulics are typically measured in pounds per square inch, which is a measurement of pressure, or force exerted with respect to area. To calculate the force used, multiply the pressure measurement by the area measurement in inches. This will give you the force in pounds, then convert that to tons.
In which direction does cool air move by water?
It will always move from an area of higher pressure to an area of lower pressure.
Area of higher pressure with winds that spiral?
Anticyclone
What is the source of wind?
The movement of air from an area of higher pressure to one of lower pressure
IS The movement of substances from an area of higher hydrostatic pressure to an area of lower hydrostatic pressure is called diffusion?
No, diffusion deals with concentrations not pressures.
