these slopes tend to heat later in the day

this.header_color = ''; highways South and west facing slopes receive heat later in the morning; therefore, the downslope to upslope takes place usually by late morning. and unenjoyable the next morning. Fuels in this area are therefore likely to be drier and less dense than fuels higher on the slope. (heat transfer by convection cycles in atmosphere as well as oceans) Areas that get little or no sun tend to be cooler than those that receive a great deal of sun. Combustible materials that aid the spread of fire form the surface to the upper canopy. Extinguishing or removing burning material near control lines, felling snags, and trenching logs to prevent rolling after an area has burned, to make a fire safe, or to reduce residual smoke. i \,JQ&r39Z^3, Microsoft Word - 071227_s190_m2_508_ev_ls_ev_jvFINAL.doc.

Topography, including elevation and aspect, affects fuels in a location differently, depending on time Crews and lookouts should monitor changing winds and fuel type changes that would allow Fire behavior and spread depend not just on the steepness of the slope, but also on aspect, or direction on a point that is representative of the larger slope area.

The gravitational force acting on a slope can be divided into two components: the shear or driving force (fs) pushing the block down the slope, and the normal or resisting force (fn) pushing into the slope, which produces friction. a tool that finds powder, soft spring snow, and dangerous avalanche Behind - Stable conditions discouraging upward motion. all of which influence fire activity.
