500 mb chart
NAM 500-mb Height Trends 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. Next to the 500 mb map is a map showing the surface temperatures across the United States at 20:15 GMT (or 20:15 Z, which is 13:15 (i.e., 1:15 PM) local time). Again, notice that temperatures are cool or cold near the trough in the western United States, for example 42°F in Tucson at 1:15 PM local time. The 500 Mb chart shows absolute vorticity (pockets of yellow, orange, red, and brown color-filled contours at intervals of 4) and winds (in m/s). X's represent regions where vorticity is at a maximum, while N's represent vorticity minimums. The height of the 500 mb level (decameters) in black. For example, "558" means 5,580 meters. Winds (knots) – The wind barb is an "arrow" that depicts the wind speed and direction. The "feathers" of the arrow indicate the wind speed while the blank end of the arrow indicates the direction the wind is blowing toward. click to animate US Department of Commerce National Oceanic and Atmospheric Administration National Weather Service National Centers for Environmental Prediction Sprint's mobile broadband usage table shows what you can do with 500 MB, 1 GB, 2 GB, and 5 GB plans, but be careful when reading the chart. For example, it says you can access 166,667 emails each month with a 500 MB plan, but that's if you only use emails and don't do any other mobile data activities (they also estimate each email to use the lower 3 KB per email figure).

On the 500 mb chart, the vorticity identified is called "absolute vorticity". This is a combination of shear vorticity and rotation vorticity that determine the total spin at any location. Take it to the MAX! The "Spin" Zone. The units for vorticity, 10-5 /sec., refers to the number of rotations (per second). The 500 millibars chart is the best for examining the overall trough/ ridge pattern. Underneath troughs, temperatures are cooler than normal while under ridges warmer than normal. WHAT TO LOOK FOR: (1) This is the best chart to assess the magnitude of vorticity. Vorticity can be generated in three different ways. They are: a. Curvature vorticity b.

The routine pressure values for which upper air maps are displayed by the DataStreme Atmosphere homepage are: 850 mb, 700 mb, 500 mb, 300 mb. The 500mb chart is a constant pressure chart which means that everywhere on the chart the air pressure is the same (500mb). This occurs in our atmosphere, on average, at a height of about 5600 meters or about 18,000ft above sea level but varies from place to place due to the density of the air column.
