Errors in the synoptic weather‐charts which cover the Greenland region

Greenland is a very large island with the outline of a human left ear. Its length in a north‐south direction is about 1,600 nautical or 1,800 English miles, and its average breadth about 600 nautical or 750 English miles. Its area is comparable roughly with that part of the United States which is east of the Mississippi River. Save for this elongated outline, Greenland's model is that of an old‐fashioned hunting‐case watch—it is a flattened dome with increasingly steep outward slopes upon its borders. With exception of a marginal ribbon of land usually less than 50 miles in width, Greenland is blanketed by a glacier which everywhere forms its surface (see Fig. 1).
