1995 two-weeks August means.

Two weeks of 8-times daily obs’s (pibal) and 2X daily radiosondes at Puerto Peñasco and twice-daily obs’s at Mexicali, MX and observations at some special US sites (Phoenix, Ajo) were used to produce 2-week mean maps at different levels to show the mean conditions during the experiment as a context for the 8-times daily Peñasco observations. Note the strong anticyclonic circulation (both shear and curvature vorticity) about the Arizona low desert. This is the same feature seen on individual maps (see "Arizona heat low example").
