A strange phenomenon on the Baltic Sea. Sea fog can be very dangerous

The long weekend began in Poland with a weather breakdown. A large number of tourists went to the Baltic Sea during this period, and it was here that violent phenomena were recorded on Thursday, May 30. There were storms and hail, but also completely different, very rare peculiarities.

People relaxing on the beach in Karwia noticed the sudden appearance of thick and milk-white fog. It turns out that it has a name and it can be very dangerous.

Sea fog over the Baltic Sea

The Baltic Sea coast in Karwia has recently been covered with sea fog. The horizon was covered by a white wall, which also “entered” the beach. She was photographed by, among others, representatives of the Storm Watchers Network. It must be admitted that it looks mysterious and quite disturbing.

For such sea fog, or advection fog, to occur, specific conditions must prevail.

Advection fog can be dangerous

Sea fog is a type of advection fog that is created by the inflow of air. It is formed when a moist and relatively warm air mass flows over a cooler substrate. Through contact with the ground, it cools down and reaches the dew point temperature, which in turn leads to the formation of fog.

In summer, such fog at sea is the norm. Then tropical air masses encounter cooler water from higher latitudes. However, it can also be observed in winter.

Advection fogs can exceed up to 500 m in height and remain in a given place for up to several days. They are often accompanied by very strong winds, which is why they can be dangerous. In addition, they are very dense and significantly reduce visibility, which poses a threat to swimmers.

The phenomenon observed in Karwia was caused by the fact that Poland is influenced by the low pressure from the North Sea. In recent days, air from the Mediterranean and Black Sea has been flowing here, which in such conditions leads to the formation of sea fog.
