Abstract
An icing-free wind vane and anemometer system for sub-zero temperatures and high altitudes was developed using two differential pressure gauges that were oriented north‒south and east‒west. Comparing the differential pressure data with data from a commercial wind system, correlation coefficients of 0.79 for wind speed and 0.70 for wind direction were obtained in summer. Using this system, wind direction and speed on Mt. Jodo, Japan were analyzed in winter. The system could be improved by the detection and prevention of plugged pipes due to ice formation.
