Description:
A C-54Q aircraft equipped with meteorological instruments was flown
three times to India to participate in the International Indian Ocean Expedition.
Flights were made out of Bombay, Gan, and Aden to observe winds,
temperatures, humidities, clouds, radiation, carbon dioxide, tritium,
turbulence, and turbulent fluxes of heat, water vapor, momentum and kinetic
energy. The present paper reports the values of 405 measurements of the
turbulence and turbulent fluxes and interprets them in terms of the monsoon
circulation and the effect upon currents and temperatures of the
Arabian Sea. Analyses of other data have been reported and interpreted
elsewhere. The aircraft turbulence measuring system used was developed earlier
by Bunker (1955) (1960). It consisted of a vertical accelerometer, a
strain-guage air-speed transducer, a vertical gyro, a platinum wire
thermometer and a microwave refractometer for humidity measurements. The
data was recorded on a nine-channel oscillograph. A digitizing reader
was used to read and punch the data on cards. The turbulent quantities
and fluxes were computed and tabulated by machine. The accuracy and limitations
of the system are discussed. While much is left to be desired in
terms of accuracies and spectral range, the results are meteorologically
useful and comparison shows good agreement with other techniques.
