摘　　要：为了提高蒸发波导模型的预报准确性,分析了海表温度梯度结构和蒸发波导模型对气海温差的敏感性,分析发现用一定深度处的海水温度代替海表温度会导致模型预报的波导高度偏低,与海上试验数据分析结果一致,得出通过精确测得海表皮层海水温度,可以提高蒸发波导高度预报的准确性。In order to improve the prediction accuracy of evaporation wave-guid model, this paper an- alyzes the sensitivity of the sea surface temperature gradient structure and evaporation wave-guid model to air sea temperature difference. The analysis finds that using the sea temperature in some depth to replace the sea surface temperature would cause the wave-guid height of model prediction to be lower,which coincides with the results of sea data analysis. The conclusion shows that measuring precisely the sea surface temperature could advance the accuracy of evaporation wave guid height prcdiction.
