What is 500 mb wind?
Wind direction and speed at 500 mb The wind blows parallel to the height contours with lower heights to the left of the wind direction. During the winter months across the United States, this means that the 500 mb winds across generally blow from west toward east, but follow the wavy pattern of the height contours.
What does a 500mb map show?
The 500mb chart is a constant pressure chart which means that everywhere on the chart the air pressure is the same (500mb). Heights increase when the air is warmer and less dense and fall when the air is colder and denser so that the distance between these height lines indicates the slope of the 500mb surface.
How is temperature related to the height of the 500 mb pressure level?
The height of the 500 mb surface is related to the temperature of the atmosphere below 500 mb — the higher the temperature, the higher the height of the 500 mb level.
How do I read a 500 MB map?
Contour maps of 500 mb height are interpreted in the same way as topographic maps of ground surface elevation. Every point on the same contour line has the same 500 mb height. For example, locate the 576 dam contour line on the map above. This line snakes across the map.

What height is 250mb?
|500 MB||18289 ft||5576 m|
|400 MB||23574 ft||7187 m|
|300 MB||30065 ft||9166 m|

Do the temperature patterns have any association with the 500 MB pattern?
We will now use the 500 mb height contour pattern to estimate the pattern of air temperature. The height of the 500 mb surface is related to the temperature of the atmosphere below 500 mb — the higher the temperature, the higher the height of the 500 mb level.
How tall is 500 MB in 6 H?
Displayed below are 6-h forecasts of 500-mb geopotential height from the most recent 00Z or 12Z NAM model run (thick dark green contours) from F00-F84. To assist in visualizing model trends, forecasts from the NAM runs initialized 12 h and 24 h earlier are overlain at the same valid time.
How tall is 500 MB in the atmosphere?
Ranging in elevation from 16,000 feet (4,980 meters) to nearly 20,000 feet (6,000 meters) this is considered the “middle” of the atmosphere. It is based upon the assumption 500 mb is one-half of 1000 millibars (at sea level) and the top of the atmosphere, zero millibars, which occurs at 30+ miles (50+ kilometers) high.
How tall is a 500MB geopotential height?
To share images easily, download the free Imgur Community Extension for Chrome. Geopotential height is the altitude at which the air is at a given pressure at a given moment. When meteorologists mention “upper-level low pressure systems”, they are referring to low geopotential heights, usually at the 500mb level.
What is the humidity level at 500 MB?
The 500 mb level chart looks at the amount of moisture in the atmosphere by displaying relative humidity. In the example below the contours are 50% relative humidity (line), 70% relative humidity (light green shading), and 90% relative humidity (dark green shading). However, remember this is only at the 500 mb level.
