- - - - occurs in the lower layers up to a height of a few hundred metres or so. The haze is usually light to moderate grey in colour.
        
        HYPOTHESIS
        
        If there is moisture haze, the air may be unstable and thunderstorms may develop.
        
        THEORY
        
        A moisture haze is basically a haze that is visible during unstable conditions with high moisture content in the air.
  - - - occur more often when the synoptic charts show a high pressure system directly overhead.
        
        HYPOTHESIS
        
        -Light winds mean haze will continue.
        
        windy means haze will spread over and cleared way.
        
        heavy rain over a few day can clear the pollution.
        
        THEORY
        
        Pollution is something we all consider as an un-natural and unfortunate component introduced since the Industrial Revolution.
  - - - occurs mainly due to bush fires or burn-offs.
        
        HYPOTHESIS
        
        a smoke haze can vary in thickness and density to the extent that it may appear like cloud.
        
        THEORY
        
        Smoke hazes can vary in height from a few hundred metres or less to several kilometres.
  - - - dust haze is made up of dust particles.
        
        HYPOTHESIS
        
        dust hazes occur in windy and dry unstable conditions.
        
        THEORY
        
        The duration can vary from a few hours with a brief strengthening of winds to a day or so in some arid areas or areas which have been affected by drought.
