SHEARLINE: The trick, whether holding station in an isolated patch of shear or running along a line that extends out of sight, is to remain within that interface where the merging of flows is most dynamic. A shear’s character can vary greatly as you travel along it, or as you or it change altitudes. Therefore, employ multiple models interdependently to visualize what is actually happening, and be ready to alter your assessment and technique at any moment. Remember that, typically, the best lift will lie in a narrow interface between two distinct wind directions or wind strengths. Drifting in a crosswind toward the opposing wind shortens a search for optimal lift. Feel and watch constantly for subtle – or not so subtle – changes. Be ready to respond immediately to differences in either the feel of the ambient air or your mental conception of physical conditions. Porpoise, veer off course as necessary to follow the shear, but stop to climb only when the lift is stronger than average or you need altitude.
