On Tuesday afternoon, heavy fog crept over Gothenburg. A couple of really thick clouds that marinated in the sea all day and then blew over the city, forming a thick fog that made a lot of GP readers know about it.
Charlotte Eriksson, a meteorologist at SMHI, believes the fog layer may remain until Wednesday morning.
– It seems that the clouds will remain overnight, then there will be a change of wind so that tomorrow it will probably be sunny again.
Whether the clouds linger over central Gothenburg or recede towards the sea is hard to tell today. But on Wednesday a little drier air will enter the city and the fog will dissipate.
– In the middle of the day on Wednesday, you can expect temperatures of up to 20 degrees, says Charlotte Eriksson.
This is fog
Fog forms when water vapor in the air condenses at a relative humidity of 95-100 percent. This can be done in two ways, partly by lowering the air temperature to the dew point temperature and partly by mixing air masses with different temperatures.
Fog components generally consist of water droplets, fog droplets, with a diameter of 10-20 microns (0.01-0.02 mm). In extremely cold conditions, the fog can consist of ice crystals, the so-called ice fog. It is usually finer than ordinary fog, but it can also give rise to beautiful halo phenomena.
The difference between clouds and fog is that the latter reaches the ground. Sometimes the fog that rises from the ground can remain as low clouds of fog.
