Atmospheric Pressure and Wind
For more information, check out the following web sites and complete the assigned tasks:
- The University of Arizona
Offers numerous images, maps, and animations. Find a cyclone on one of the images.
- The University of Wyoming
Offers the user the ability to produce upper air maps at different levels for any portion of the globe. Find the height of the lowest contour line on the 500 mb map of North America.
- ETA Model Forecasts
Includes maps of the forecasted upper air patterns for a number of upper level pressure surfaces, based on one of the primary forecast models. Identify the three parameters depicted on the sea level pressure and precipitation forecast chart.
- Current Surface Pressure
Here one finds color contour maps of sea level pressure from the Unisys Weather site. Find the lowest pressure (in millibars) on the map.
- Current Upper Level Data
This site contains height contours (in white) and wind barbs, showing speed and direction of wind, from the Unisys site. Name the states over which the wind speeds are the fastest.
- Forces and Winds: An Online Guide
This web site provides an online tutorial on atmospheric forces and wind. It uses numerous diagrams to illustrate the concepts described in the chapter. Watch the online movie on the Coriolis force.
- Latest Maps of the Jet Stream
These maps of North America show the wind velocity at 300 mb (in the upper troposphere), which indicates the location and strength of the jet stream. Identify some of the states over which the jet stream is flowing.
- Weather World 2010
A weather site designed and administered by the University of Illinois-Urbana/Champaign. List some of the current weather products.
