Usually it is taken that winter high pressure means clear skies and thus colder temps. But the graph says it doesn't really matter as much. Temps will increase or decrease regardless of the surface pressure.Eric Lundellhttps://www.blogger.com/profile/17914784378747801359noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-89794306370714345662014-02-25T10:25:31.662-09:002014-02-25T10:25:31.662-09:00Eric,

I would gladly plot the data against altitude, except that the height values are missing for most of the levels in the data set I am using (from NCDC). The top of the chart, at 800 mb, is around 5500-6500 feet but varies considerably of course.<br />Richard Jameshttps://www.blogger.com/profile/08313902028896263276noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-81012748016596020462014-02-25T07:40:32.400-09:002014-02-25T07:40:32.400-09:00Is the cutoff at the bottom due to geopotential he...Is the cutoff at the bottom due to geopotential height? If so, would it be too much to put the y-axis in feet? That means more to casual observers.<br /><br />If you really want to do work: take a north-south slice (crossing Fairbanks) height profile across the stretch of Alaska maybe using reanalysis data. That would be cool. Over a few slides or animations you would see the progression of warm and cold air at the different latitudes and altitudes. Just putting that out there.Eric Lundellhttps://www.blogger.com/profile/17914784378747801359noreply@blogger.com
