Title: Some meteorological parameters for atmospheric dispersion modelling at Lucas Heights, NSW, Australia, 1975 to 1983.
Authors: Clark, GH
Issue Date: Oct-1985
Publisher: Australian Nuclear Science and Technology Organisation
Abstract: Meteorological data collected in the years 1975 to 1983 at the AAEC's Research Establishment at Lucas Heights New South Wales Australia have been summarised. Wind speed direction and turbulence trace types from 7 and 49 m temperature difference between 9 and 49 m ambient temperature and precipitation rates have been extracted as 30 minute averages. Seasonal wind speed and direction roses are summarised for 7 and 49 m together with wind direction persistence statistics which are relevant to short-term (accident) releases of atmospheric pollutants. A 'split-sigma' approach has been adopted for definition of the atmospheric stability categories: a 'turbulence' method using the wind direction turbulence trace types for the horizontal diffusion category; and the US Nuclear Regulatory Commission temperature gradient criteria are combined with Smith's 1972 scheme for the vertical diffusion estimates. Statistics on 10, 50 and 90 per cent probability and average wind speeds and atmospheric stabilities are also analysed. An extensive data summary is included.
