TTÜ marine scientist: The ice cover in the Baltic Sea has started to decrease rapidly

Liivi ja Soome lahes liigub jää tuulte tõttu ringi.
Uiboupin ütles, et jääd ei teki enam palju.

Edela ja lõunakaare tuuled puhuvad lähipäevil.
See põhjustab jää lagunemist mitmes kohas.

Jääkattele võib koguneda veekiht.
Edela tuuled ja veetaseme tõus Eesti rannikul põhjustavad seda.

2010/2011 talvel oli jääd veel rohkem.
See aasta ei olnud ekstreemne, vaid üle keskmise.
Talv oli huvitav, sest jää tekkis alles jaanuari alguses.

Mudel on TTÜ meresüsteemide instituudi loodud.
Projekt DTO4OWE on mudeli allikas.
The ice cover in the Baltic Sea has decreased rapidly.
Currently, the ice cover size is 140,000 square kilometers.
Previously, it has been 180,000 square kilometers.
TTÜ Professor Rivo Uiboupin explained this.
According to the forecast, there will still be ice in Väinameri in the coming days.
In the Gulf of Riga and the Gulf of Finland, the ice moves around due to the winds.
Uiboupin stated that not much ice is forming anymore.
The peak of winter has passed.
The maximum ice extent in the Baltic Sea will be reached at the end of February.
Southwest and southeast winds will blow in the coming days.
This causes the ice to break up in several places.
There is open water near the Saaremaa-Hiiumaa ice road.
It is five kilometers away.
A layer of water may accumulate on the ice cover.
Southwest winds and rising water levels on the Estonian coast cause this.
In Väinameri, the water level has risen by 30–40 cm in the last ten days.
Satellite images show the mapping of ice conditions in the Baltic Sea.
This winter has been icier than the average of the last 30 years.
In the winter of 2010/2011, there was even more ice.
This year was not extreme but above average.
The winter was interesting because the ice only formed at the beginning of January.
The TTÜ ice condition forecast shows ice concentration and drift speed.
The forecast is updated daily.
The accuracy of the model varies in different weather conditions.
The model was created by the TTÜ Marine Systems Institute.
The DTO4OWE project is the source of the model.
