SUMMARY OF RAWINSONDE MEASUREMENTS OF TEMPERATURES,nPRESSURE HEIGHTS, AND WINDS ABOVE 50,000 FEETnALONG A FLIGHT-TEST RANGE IN THEnSOUTHWESTERN UNITED STATES

摘要

An investigation was conducted of the temperatures, pressure heights, and winds from data of four rawinsonde stations in the 100-millibar to 2-millibar pressure region (altitudes of approx. 50,000 to 140,000 ft) along a flight-test range in the southwestern United States. This range, referred to as High Range, extends from Edwards, Calif., to Wend over, Utah, to accommodate flights by the X-15 and other high-performance craft. Comparisons of the average temperatures and pressure heights are made with those of the U.S. Extension to the ICAG Standard Atmosphere.nIn the 100-millibar to 10-millibar range the largest differences between the yearly average temperatures of the stations and the temperatures of the U.S. Extension to the ICAO Standard Atmosphere are at 100 milliards and 25 milliards. In the 10-millibar to 3-millibar range, the differences between the yearly average temperatures of the Edwards station and the temperatures of the U.S. Extension to the ICA0 Standard Atmosphere increased with altitude. In this range the temperatures of the Edwards average sounding are lower than the temperatures of the Standard Atmosphere.
