GOES Animations and Microsoft Edge
Due to the April 9 Windows 10 update, GOES animations are broken in the Microsoft Edge browser. We are aware of the problem and are seeking a solution. Meanwhile, please try a different browser to access this site.
About Air Mass
Air Mass RGB is used to diagnose the environment surrounding synoptic systems by enhancing temperature and moisture characteristics of airmasses. Cyclogenesis can be inferred by the identification of warm, dry, ozone-rich descending stratospheric air associated with jet streams and potential vorticity (PV) anomalies. The RGB can be used to validate the location of PV anomalies in model data. Additionally, this RGB can distinguish between polar and tropical airmasses, especially along upper-level frontal boundaries and identify high-, mid-, and low-level clouds.
