Abstract : Latitudinal and seasonal variations of calculated evaporation duct height climatologies are examined to determine which of the four surface-measured input parameters to the calculation of duct height -- air temperature, sea surface temperature, dew point temperature, and wind speed -- has the largest effect on the climatological tendencies. Based on a sensitivity analysis of the four parameters, sea surface temperature appears to cause most of the latitudinal variation. Seasonal variations of median duct height apparently are caused by the stability (indicated by the difference between air and sea surface temperatures) and dew point temperature, and, to a lesser extent, by wind speed.
