Excerpt from Estimating Upslope Convective Windspeeds for Predicting Wildland Fire Behavior Slope winds are local diurnal winds present on all sloping surfaces They flow upslope during the day as the result of surface heating, and down slope at night because of surface cooling. Slope winds are produced by the local pressure gradient caused by the difference in temperature between air near the slope and air at the same elevation away from the slope.

Excerpt from Estimating Windspeeds for Predicting Wildland Fire Behavior By equating integrated bulk drag due to crown foliage to the shear stress at the top of the crown layer, a model for relating windspeed within and below a uniform forest canopy to windspeed 20 ft (6 m) over the canopy is developed. Important variables in this model include stand height, crown closure, foliar surface/ volume ratio, and crown bulk density. Comparison of model predictions with reported experimental measurements shows good agreement. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
