✦ Synopsis

three-dimensional, nonhydrostatic, terrain-following numerical model was used to investigate the Adelaide Gully Wind of South Australia, and it reproduced well this severe downslope wind. Simulational results showed that onset and strength of the Adelaide Gully Wind is critically dependent on the upstream wind and potential temperature profiles, and the appearance of this local wind is also strongly influenced by the complicated three-dimensional effect of the real topography. Sensitivity study of the numerical model showed that a horizontal grid size of 1 km is required to resolve the fine structure of the Adelaide Gully Wind.

## Abstract A detailed analysis of the rainfall of Adelaide, South Australia, has shown that throughout the 95 years 1839‐1933 there has been a definite oscillation, with a period and amplitude of approximately 23 years and 30 days respectively in the incidence and duration of the winter rains.

The form of the wind profile is of concern in many problems involving exchange and diffusion in the canopy formed by vegetation. Yet, we have little quantitative information on the relationship between the wind profile and properties of the foliage because of practical difficulties in modifying exis
