Statistical forecasting of sea level changes in the Baltic

Abstract [sv]

Genom utveckling av vattenståndsdata från 6 svenska observationsstationer i empiriskt ortogonala funktioner har erhållits en mycket enkel bild av Östersjöns respons på atmosfärens inverkan genom vind och tryck. Inte mindre än 65.5 procent av den totala variansen representeras av en allmän höjning eller sänkning av hela ytan. Tidsskalan är här av samma storlek som tidsskalan hos storskaliga atmosfäriska störningar. Detta beroende har utnyttjats för att bestämma sådana regressionsekvationer mellan lufttrycksfält och vattenståndsvariationer som sedan utnyttjas för prognoser. I den statistiska behandlingen har tekniken med empiriskt ortogonala funktioner utnyttjats i hög grad.

Abstract [en]

By expanding sea level data from 6 Swedish observation stations inte empirical orthogonal functions a very simple picture of the response of the Baltic to atmospheric forcing is obtained. It is found that not less than 65.5 per cent of the total variance is due to a general rise or lowering of the whole surface.The time scale corresponds to the time scale of large scale atmospheric disturbances. This inderdependence has been used in order to establish a regression equation between surface pressure fields and sea level variations which is used for prediction. In the statistical treatment extensive use is made of the empirical orthogonal function technique.
