The observations here described were made during the Wordie 1937 Expedition to North-West Greenland and to the Canadian Arctic (Wordie 1938). They were not undertaken primarily with a meteorological end in view, but were incidental to the main purpose of the expedition, which was an investigation of cosmic radiation at great altitudes and high latitudes (see the adjoining paper, Carmichael and Dymond 1939). A knowledge of upper winds was necessary before the balloons carrying cosmic-ray apparatus could be launched with a reasonable chance of recovery, and accordingly from July to September 1937 a number of pilot balloon flights were made, the results of which are sufficiently interesting in themselves to be discussed. The cosmic-ray balloon flights also yielded information about upper winds and on one occasion made possible a meteorograph sounding.
