Abstract

Abstract

The spectrum of temperature fluctuations have been measured by 1m m and 10m m diameter wires. A method for measuring outer scale is presented. The results of measurement show that at least 50% temperature spectra deviate from kolmogorov's “－5/3 low” over complex terrain. The results measured by a single sensor and a couple of sensors respectively agree well with each other. 80% of the outer scales are less than 7 meters.
