Figure 3. Thermal centering in different wind conditions.

Figure 3

(a) Climb rates under low wind shear conditions (<2 m/s) and under strong wind shear conditions (>6 m/s) were not significantly different between age classes, but (c) under intermediate wind shear conditions (2–6 m/s) adults (blue) exhibited higher climb rates than juveniles (red). (b) Histogram of the estimated horizontal wind speed in thermal soaring events by RAMS. (d) The difference between mean climb rate of juveniles and adults as a function of lateral wind speed. Best fitting model among a hump-shaped model (second-order polynomial, solid black) and no difference among age classes (y = 0, dashed grey) are presented. Error bars represent mean ± SE.
