Hypothesis: There are zones more inclined to experience wind shear than other areas. These zones may be non-mountainous areas. Physical observation: Ground based observer views SCT022 layer hauling ass from the north-north east. Simultaneously a BKN layer at 050 is hauling out of the SSW. Similar observations have been made each day for the previous two week period. Sightings include morning, noon, and twilight observations. Example: Cape Cod, Massachusetts Winds aloft for Boston and Nantuckett, the two closest wx stations 52 nm and 27 nm respectively.
