It is important to note that convective cells can cause air currents both upward and downward. Upward convective currents carry pollutants many kilometers high into the atmosphere. At these high altitudes advective currents and prevailing winds can transport these pollutants vast distances very quickly. As air spreads from the rising column, it is cooled and falls back down to the earth. This results in a circular rotation of the air.  3, fiche 1, Anglais, - advective%20current

Drainage of the lake-beds, related to a seasonal phenomenon of dust storms between February and May, has also affected air quality. The midday air temperatures during the dry season generate strong advective currents that elevate salt and clay particles from the former lake bottom. These particles are blown into the city by the prevailing easterly winds.  1, fiche 1, Anglais, - advective%20current

advection : The horizontal movement of air around the world is known as advection. Advection is the primary mechanism responsible for long range transport of pollutants. Although transport of pollutants via advection is minuscule at the earth's surface, at heights above 1000 m, where friction become negligible, wind velocities of 400 km/hr can carry pollutants at extremely fast rates.  3, fiche 1, Anglais, - advective%20current

Les masses d'air polluées et riches en ozone sont d'abord transportées vers la région de l'Atlantique par la cellule de haute pression qui se dirige vers l'est. La cellule se déplace le long de la côte est de l'Amérique du Nord, créant une poussée d'air du sud ou du sud-ouest qui dirige les polluants par advection dans la région de l'Atlantique.  3, fiche 1, Français, - courant%20d%27advection

To understand the problem, it is also necessary to understand Long-Range Transport of Air Pollutants(LRTAP). LRTAP refers to the transport of pollutants by the winds over long distances, hundreds and even thousands of kilometres. These pollutants, moving long distances through the atmosphere are transformed into secondary products which then react chemically with the water vapor in the atmosphere and the result is acidic water vapor.  1, fiche 3, Anglais, - long%2Drange%20transport%20of%20air%20pollutants

The Forest Insect and Disease Survey(FIDS) program has been merged with the Long Range Transport of Air Pollutants Program to form a nationally focused Forest Health Network. This Network has a forest health monitoring component that will assess and report on the condition and changes in the health of Canada's forests. The Forest Health Monitoring group will monitor forest health plots, map major forest disturbances, and support the Plant Protection Division of Agriculture and Agri-Food Canada under the Plant Quarantine Act. All CFS establishments are involved in the Network, with Fredericton as the lead centre.  1, fiche 4, Anglais, - Forest%20Health%20Network
