Surface winds above what mph help determine direction of fire spread, help to carry firebrands ahead of the fire, and increase the supply of oxygen to the fire? As a result, north facing slopes have traditionally been left in forest while south facing slopes are used for high pastures (Fig. Can become prevalent after a fire in timber areas.

All of these countries measure their ski slopes by the percentage of the slope and not the degree angle: Beginner slopes: 6% to 25%. Northeast. Since east-facing slopes are also the first ones during the day to end up in the shade, the valley wind there generally stops by late afternoon. South and Southwest facing slopes South and southwest aspects receive the most direct sunshine, leading to higher fuel temperatures, drier
