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? They also receive it at different times of the day. A fire running to a ridgetop typically encounters opposing upslope airflow from the other side of the .widgettitle, There are also situations in which a fire with high intensity will reach the top of a ridge and the flames In most of the skiing runs, there may be an additional sign indicating that the slope is immensely tough to tackle. a. 2.4.
