Abstract

The effect of geophysical noise on the precision of momentum flux measurements is examined. The dominant contribution to the uncertainty of momentum flux estimates scales with the geometric mean of the energy in horizontal and vertical wind fluctuations. To obtain statistically significant measurements of the momentum flux, long integration times are necessary since the flux is typically a small fraction of the geometric mean energy. For example, when the fraction is 1%, at least 16 days of stratospheric measurements will be needed for reliable flux estimation.
