摘　　要：提供了一种实用的低层大气折射率剖面的短时预测方法。针对一天中折射率变化最为剧烈的日出日落前后的大气折射率剖面的试验测试，使用这个方法进行了预测。它用微波折射率仪等精密空气折射率测量设备测得的时变参数推算未来2～3h的低层大气折射率剖面，结果表明预测结果和实测的大气折射率剖面相吻合。In this pape a practical method is provided, which is used for forecasting lower atmospheric refractivity profile in short time. For an experiment which sounding the profile at sunrise and sunset when the refractivity varies violently, it is used to forecasting the profile. With time various parameters measured by microwave refractometer it can forecast the lower profile in 2-3 hours, the forecasted profile agreed with the sounded profile very well.
