Measurement of Air Temperature and Wind Velocity from One to Eighty Centimeters Above the Sea Surface

摘要

A wave following mechanism was designed and tested at the field station operated by the Institute of Oceanography of the University of British Columbia. Separate measurements were made of temperature and velocity fluctuations by sensors attached to the vertically moving follower arm at heights of 1 cm, 5 cm, 24 cm, and 78 cm above the sea surface. These data were analyzed both by analog and digital methods. While the data generally follow the -5/3 power law proposed by Kolmogorov, there are significant departures from existing theories which could prove important. Since most air-sea interactions take place below 30 cm and few measurements have been made below this level, the wave follower could be a useful tool in investigating near surface phenomena. (Author)
