Cumulated wind speed
WebOct 21, 2016 · In boreal ecosystems, wildfire severity (i.e., the extent of fire-related tree mortality) is affected by environmental conditions and fire intensity. A burned area usually includes tree patches that partially or entirely escaped fire. There are two types of post-fire residual patches: (1) patches that only escaped the last fire; and (2) patches with lower … WebDec 7, 2012 · Assuming that we can measure the roll angle φ (t), the pitch angle θ (t) and the velocity v (t), Equation (5) could be used to estimate the curvature σ.Indeed, by integrating Equation (5) we can compute the instantaneous curvature σ (t), provided that an initial condition σ (0) is given. Similarly, knowing the profile σ, if we integrate the non …
