High Smoke over the High Plains

High Smoke over the High Plains

This is a classic example of a smoke plume from a large wildfire. Here the smoke was hoisted from its Laramie Range source fire in Wyoming, upward into the middle and upper levels of the troposphere by the buoyancy of the source heat, then blown well downwind in two layers of flow. Southwesterly winds aloft prevailed where the thick band is visible, at right. Northwesterly flow at higher levels sheared off thin parcels of smoke from the top of the plume and carried them off to the upper left (southeast). During the summer of 2002, pervasive drought across much of the West, and sometimes poor forest management practices, contributed to wildfires which torched around four million acres of land.
