An analysis of one year of surface layer meteorological data from the Arctic pack iceBaumann, Richard James 17 July 1978 (has links)
The thesis describes the properties of surface wind and air
temperature time series recorded at three locations on the pack ice
of the Beaufort Sea. Time series consisting of sequential one-half
hourly means were constructed for a period of approximately a year.
A diurnal fluctuation in air temperature is found for the late summer,
early fall and spring seasons only. Wind speed does not show a
significant diurnal fluctuation for any season. There is very little
seasonal variability in the wind speed while significant variation is
present in the air temperature. The integrated wind speed spectrum
(i. e. variance) is 80% less than the integrated sum of the wind component
spectra indicating that for periods longer than a day, directional
fluctuations contribute much more to the variance of the wind record
than do speed fluctuations. Although the measurements only approach
the microscale region, there seems to be no consistent indication of
a microscale peak in the variance preserving representation of the
wind speed spectrum. Time series of daily mean horizontal divergence
and vertical component of vorticity for both the wind field and
ice motion are examined. For a period of 355 days there is significant
negative correlation (-0.65) between the wind divergence and
wind vorticity series and significant positive correlation (0.65)
between the wind vorticity and ice vorticity series. / Graduation date: 1979
