Georgia Burn Manager Certification Practice Test

When planning a burn, you want a steady, single-direction wind to keep the fire moving along your prepared containment lines. A front between two weather systems often creates wind shear—the wind speed and direction change with height. Surface winds may blow one way while winds higher up blow another, and gusts can occur as the front shifts. That combination makes the flame front tilt irregularly, embers get carried unpredictably, and spotting becomes much more likely. All of this makes the fire much harder to control. Other factors like humidity being very high or constant temperature don’t inherently produce that same dangerous instability. Rain approaching could help control or extinguish the burn, and constant temperature isn’t the primary driver of erratic behavior in this setup. The key issue here is wind changing between ground level and aloft.
