Aircraft noise measurements from the Boeing 737, made at Orange County Airport, Santa Ana, California, during operational conditions, are statistically correlated with the local meteorological factors including wind force and direction, temperature, humidity barometric pressure, ceiling and visibility. The correlation was carried out using regression techniques and indicated that there is a significant inverse correlation between temperature and noise level. Wind speed appeared to be of significance in one calculation that included wind speeds up to 25 knots, but was not significant when the range of wind speeds was 15 knots and below.
