What is a chute in topography?
Chute. Fairly narrow and straight depressions that lead up a ridgeline.
What are the three general winds?
There are three types of wind that are associated with wildland fire: general winds resulting from atmospheric activity, local winds resulting from unequal heating of land and sea surfaces, and winds resulting from a fire’s buoyancy (also called entrainment).
What are daily wind shifts called?
(Blank), winds are a by-product of the daily heating and cooling of the earth’s surface referred to as the diurnal cycle. Local Winds. How does hilly terrain cause various changes in local winds? As the terrain such as a mountain or hill rises, the heat will create an up-slope local wind.
What are three contributing factors to extreme fire behavior?
Identify the THREE fuel factors MOST indicative of factors leading to problem or extreme fire behavior. The correct answers are characteristics, moisture, and temperature.
What is a saddle topography?
Topography. A saddle is the lowest area between two highlands (prominences or peaks) which has two wings which span the divide (the line between the two prominences) by crossing the divide at an angle, and, so is concurrently the local highpoint of the land surface which falls off in the lower direction.
What is a river chute?
chute, or Cutoff, in a river, shortcut across a meander (q.v.). loop that shortens and straightens the course of the stream. Chutes are formed by lateral erosion of the bank of the upstream arm of a loop, which causes the stream to cut through the neck of the loop into the downstream arm.
Why do night inversions form?
The inversion forms because air in contact with the cooling ground cools through conduction. On a clear night with light winds, the delay in cooling the air not in contact with the ground results in the air temperature increasing with increasing height above the ground.
What is the brush fire triangle?
There are three components needed to start a fire: fuel, oxygen, and heat. This is commonly referred to as the fire triangle. If any one of the components is missing, a fire cannot occur.
What is a land saddle?
A saddle is the lowest area between two highlands (prominences or peaks) which has two wings which span the divide (the line between the two prominences) by crossing the divide at an angle, and, so is concurrently the local highpoint of the land surface which falls off in the lower direction.
