What constitutes a good smoke dispersion day?
A good day for burning may not necessarily be a good day for smoke dispersion. Smoke is dispersed by mixing it with clean air. Generally, the greatest amount of clean air is available during the warmest part of the day and during periods of unstable weather (rainy or windy conditions). Warm, sunny days, often associated with high pressure systems, indicate that there is a limited amount of clean air with which to mix the smoke. While these conditions may be ideal for burning, smoke is often trapped near the ground and is unable to disperse. See also Smoke Dispersion: the Key to it All.
