The most important factor in topography as it relates to wildfire is slope. Unlike humans, fires usually travel uphill much faster than downhill. WebTemperature affects fire behaviour indirectly through influence on fuel moisture content and local wind formation (e.g. sea-breezes). So, as air temperature increases, fuel moisture content tends to decrease, and vice versa. Dew can form which can cause fire to slow or even be extinguished. boo-boo nyt crossword
