A simple method to improve geopotential height accuracy in numerical forecasts |
| |
| Abstract: | A simple method to improve the forecast accuracy of geopotential height in numerical models is described here. The method combines the objectively analysed height field and model-produced height tendency to form a final forecast rather than forecasts the height itself directly. The preliminary results of six tests show that the RMS error of height forecast has been reduced from 2.91 to 1.93 ten meters and correlation coefficient increased from 0.879 to 0.941. |
