Hobby of yours?

Marc

A few yrs ago I joined a network I have called "weather nerds", who submit to a presentation/lesson on how to use "official" gauge, and buy said gauge ($25), and agree to report periodically.

Network originated in Ft Collins, CO after a serious flood there killed people. Weather scientists decided they needed more data to maybe get better at weather forecasting. They welcome anyone who wants to join.

I'm a weather nerd. It's fascinating stuff. A lot of activity swirls around the Great Lakes. I have a particular interest in how city "heat centers" effect 500mb level vorticity.

Some of my favorite sites. I like the Unisys site quite a bit.

Third site down, click on "500 mb Plots", then choose "Loop" under the Time category. It provides the clearest picture of vorticity movement across North America. If one wants to understand weather, one must understand 500 mb level weather patterns.

They're isobaric lines , are they?

The surface plot is doppler, isobars, temp/RH gradients, and pressure gradients. Everything one needs.

The GFS/Avn 500 mb loop is a 5 day projection of vorticity path and pressure gradients. It's fascinating how often the projections are exactly perfect.
