Abstract: Using the winds in Japan as an example, the validity of the vectorial treatment of the surface wind in climatological investigations has been demonstrated, and the expressions for climatological mean and variability of the ...

Abstract: Climatelogical aspects of the geostrophic wind calculated from geopotential heights in the planetary boundary layer in Japan have been investigated. The mean geostrophic winds at the 850 mb level nearly agree with the ...

Abstract: In a recent paid, the author reviewed methods for estimating the mean and the standard deviation of wind direction. Some comments on this subject are now added. If large sporadic eddy fluctuations do not occur in a sampling ...

Abstract: Spectra of the surface wind at Marcus Island (24°N, 154°E) in the subtropical Pacific area wore constructed over a wide frequency range from 10?1 to 5 ? 10?5 Hz (periods from 6 h to about three years). The major kinetic ...

Abstract: Proposed single-pass methods for estimating the mean (D?) and the standard deviation (σd) of wind direction and other problems in wind statistics have been evaluated using extensive field data. It can be concluded that ...

Abstract: The daily variation of the surface wind at Marcus Island (24°N, 154°E) in the subtropical Pacific area has been investigated with respect to the semidiurnal atmospheric tide. The semidiurnal oscillations of scalar wind ...
