An intermittent side wind up to this strength can easily cause phasing between left and right
arrays due to variable comb filter effects above 107 Hz. However, as both left and right arrays
may be similarly affected (unless there is excessive local turbulence) most of the phasing will
be audible at high frequencies.
If phasing is particularly audible, a 6 dB/octave lowpass filter set to about 8 kHz sometimes
helps reduce the audible effects until the gusty weather has passed.
Wind and temperature gradients significantly affect off-site coverage but their
individual effects can be quite subtle on-site. However, the combined effects of
wind and temperature gradients may cause significant on-site coverage degradation
if it isn’t taken into consideration at the system design stage.
Make sure you design large-scale sound systems to provide 10-15% extra depth and width
coverage as a contingency.
