On days like these, when blizzard conditions may develop on the High Plains and there is a high risk of severe thunderstorms and tornados across the South Central and Southeastern States, many of us tune into the Weather Channel or check online weather sites to witness and understand the dynamics of these storm systems.
In my experience, earth.nullschool.net offers one of the more fascinating views of wind patterns across the globe. One can easily see the location of fronts where wind directions clash and appreciate the onshore flow of moisture as winds streak across ocean or gulf waters, sweeping in their cargo of moisture that will fall as rain or snow; of course, rising humidity, produced by such onshore flow, fuels severe thunderstorms where it encounters an approaching cold front or dry line.
The ever-changing wind patterns also illustrate the location of high pressure domes (around which the winds move clockwise) and the position of tight counterclockwise swirls around centers of low pressure. I highly recommend this online site for any weather buff.
Note: The wind directions mentioned above for high and low pressure areas are for the Northern Hemisphere. The wind map on the website clearly demonstrates that they are just the opposite in the Southern Hemisphere.
