LITTLE AMERICA V MICROMETEOROLOGY PROGRAM DATA AND ANALYSIS

At Little America V the temperature range of each of the 9 coldest months is large, as is the annual range. Minima are controlled by advection of cold air from the interior and maxima by advection of warmer air from the Ross Sea area. The winter lacks a distinct temperature minimum, and mid-winter r...

Description
Summary:At Little America V the temperature range of each of the 9 coldest months is large, as is the annual range. Minima are controlled by advection of cold air from the interior and maxima by advection of warmer air from the Ross Sea area. The winter lacks a distinct temperature minimum, and mid-winter reversals of temperature trend occur. Micrometeorological wind and temperature profiles in the lowest 8 m of the atmosphere were recorded at Little America V in 1957, and hourly means of temperature for about 3,000 hours and wind speed for about 500 hours are published as Appendix B of this report. Procedures used to analyze the 1958 micrometeorological data from the South Pole Station are followed in this analysis and results compared with the less complex relationships at the South Pole. Prepared in cooperation with Ohio State Univ., Columbus, Inst. of Polar Studies, Contrib-97.
