Does wind have an effect on radio waves?
Wind does not have an effect on radio
waves. Wind cannot affect radio waves because the air particles associated with wind are far too small for the radio wave to bounce off of. Radio waves can only bounce off of large objects.
Wind can be measured by Doppler radar.
Doppler radar uses microwaves instead of radio waves. Microwaves are a lot
smaller and can detect such
small things as clouds, dust, and precipitation.
Clouds, dust, and precipitation are moved around the atmosphere by the wind.
Since scientists can measure these things, they can also measure the speed and
direction of the wind!
