How does weather impact aircraft noise?

Monday September 23 2019

Weather conditions affect the transmission of aircraft noise in several ways.  First, on hot spring and summer days, especially those over 100 degrees, aircraft climb more slowly placing them closer to communities under the flight paths.  Secondly, when skies are very cloudy, and the clouds are low to the ground, the noise from aircraft can rebound off the clouds and back to earth, making planes seem louder.  Lastly, on very windy days sound can travel much further downwind, resulting in aircraft noise carrying farther than usual.
