Meteorology and Air Quality

The module Meteorology and Air Quality is a tutorial shell around a pre-existing simulation of pollution dispersal from a chimney stack of variable height. Its units explore the effect of differing atmospheric layers, lapse rate, and wind direction. Animations and mini-simulations are used. Later units repeatedly launch an external simulation with varying sets of parameters explained.


Interactive animations convey lesson like change in air temperature with altitude.


Meteorologists classify seven levels of Stability, depending on sun-strength and wind-speed.



An “inversion” layer (temperature rises with altitude) can trap pollution.


Stochastic variation of wind direction and its cumulative effect are simulated.


Mathematics of the dispersion model in SMOKE are explored step by step.



Blackadar’s SMOKE simulation (MS-DOS) is launched with varying parameters.
