WV Imagery Overlaid with Model Wind Fields

Starting with 500 hPa, click each tab, review the image, and then answer the question below it. When you have finished all three questions, move on to the next page.

There's at least one 500-hPa high (anti-cyclonic) and low (cyclonic) on this image. Click each of these areas on the map. When finished, click Done.
