Fig. 7. (A) Peak wind velocities measured by the anemometer at distances
2060 cm from the target (N=94). The anemometer was within
1830 cm of the target in 77% of the trials. The shaded boxes indicate
the percentage of measured peak wind velocities that fell between 049,
5099 and >100 cm s1 for the data collected with
the anemometer within 2030 cm of the target only. (B) Distribution of
peak accelerations for 66 of the trials in A. Peak acceleration was calculated
using the onset time of the anemometer detecting the bat-generated wind to the
time of the peak velocity. (C) Comparison of peak velocity and peak
acceleration for each trial in B. For bat-generated wind, peak velocity and
peak acceleration were closely related, with peak acceleration increasing
exponentially with increasing peak velocity. The equation for the exponential
best fit line is
f(x)=4.980398x101*exp(4.814839x102*x).
