Abstract: The heat stored in the ground and the transport of this heat to and from the atmosphere can be important considerations in numerical models of the atmosphere. This note considers the preformance of the conventional approach ...

Abstract: The increasing requirement for data about turbulence in a city environment, particularly in relation to building design and the imminent operation of aircraft from this environment, has prompted the measurement of the ...

Abstract: It has been hypothesized by Dutton et al. (1969) that intermittent turbulence should show a frequency-phase organization. Because of inherent difficulties in measuring phase, confirmation of this effect has been difficult ...

Abstract: The self-similarity concept has proved useful in describing turbulence for aircraft design purposes. There is an increasing awareness of the interaction of the turbulent planetary boundary layer and buildings and structures. ...

Abstract: The effects of time-averaging and length of record on the variance of horizontal wind speed are considered through power spectral techniques. These effects are applied to a height profile of intensity of turbulence (ratio ...

Abstract: Using an assumed spectral density function, the ratio of the maximum gust of t seconds averaging time, drawn from a sample duration of T seconds, to the maximum S-second gust from a Θ-second sample is derived using the ...
