When the wind is coming from the southwest, I notice a blue or purple haze in the air that I am assuming is from the the big stack in Sudbury.
Does any out there have any facts? I always enjoy those days when the wind is from the north. |

A very small% is from the Sudbury stack, whenever there is a southwest wind it means a farm front has gone through and you will find the air is RELATIVELY warm and much more humid, warm air being able to hold more moisture than cold air. The haze is part moisture, part pollution, from southern Ontario and the American midwest (coal plants!)When the wind switches to the northwest a cold front has gone through, the air is RELATIVELY colder and much drier therefore much less humidity and no pollution since the airmass is coming directly from the arctic.

Re above post
Farm fronts are exceedingly rare, southwest winds mean a WARM front has passed. |

Unfortunately, air quality is now a global issue. |
