It also provides information that allows the dispersion model to simulate the effects of air flowing over hills or splitting to flow around hills.

Exponential dispersion models are statistical models in which the probability distribution is of a special form.

The dispersion models vary depending on the mathematics used to develop the model, but all require the input of data that may include:

Based on this information, meteorological and atmospheric dispersion models are employed to predict the spatial distribution of pollution concentrations over the area.

There are several parameters which must be considered when creating a dispersion model, including oil-slick thickness, advection, resurfacing and wave action.

The suite of local-scale (0 - 30 km) dispersion models available at the Institute includes:

Jørgensen B (1997) The theory of dispersion models.

This includes the research and development of improved dispersion models for emergency response and air quality forecast models.

Austal2000 is an atmospheric dispersion model for simulating the dispersion of air pollutants in the ambient atmosphere.
