But I will say that there are definite anomalies in Weatherbug maps -- there's a persistent region of low humidity (20-40% lower than surrounding areas) over a rural part of Ontario containing the Cote Gold Project, an open pit gold mine; I've been unable to find data for that region in other data sets and have concluded it's due to a faulty weather station. Also, there's a remarkably low pressure blob over rural Venezuela in the first image of my post. | |

I'm not convinced that those are resolved features in the underlying dataset, in the same way that I'm not convinced that those neatly radial wind maxima over towns are resolved features. A lot of what the casual observer will be seeing in these maps is the effect of sampling/interpolation/downscaling decisions. | |
