Did Föhn Winds Just Melt Two Miles of East Antarctic Surface Ice in One Day?
UPDATE — Cloud Shadows and Bluish Coloration
Layer analysis of the November 27 MODIS satellite image in bands M 1-12 reveals two cloud shadows near the suspect melt pond (an issue that commentators Hendrick and Sammy raise in discussion below). The separate true color image provides comparison and generates the impression that the suspect melt pond is simply a remnant cloud shadow from the kidney-shaped cloud in the M 1-12 band image.


The cloud shadows move from frame-to-frame providing a further negative confirmation.
Though it is now certain that the large blue blotch in this satellite image is not a melt pond, a bluish coloration appearing over a broad swath of the above region in both the November 27 and November 28 image frames appears to indicate the presence of surface melt. So the downsloping wind related warming may well have produced a more subtle surface melt for this region…
