SALINITY PREDICTION AND ITS ANALYSIS FOR THE SOUTHERN HUANGHAI SEA

Based on the prediction experiments on the salinity distribution of the southern Huanghai Sea in spring (April-June) from 1978 to 1980, two salinity-prediction methods suitable for the region are obtained.The methods are briefly introduced and the marked factors affecting salinity variation and the prediction error are analysed.Results from the prediction experiments indicat the absolute prediction error of ensemble mean as 0.43‰, the relative error as 25%, the deviation error as -0.16‰, and the stations with prediction error less than 0.5‰ accounting for 72% of the total.There is a little difference between prediction tendency and measured data.
