Adriatic Fog


We stopped by the sea. The Adriatic sea. There were many more people than we expected. Some walking, most foraging for clams. And there was fog. Not a lot of it, but enough to make a difference.



Fog is a complex atmospheric phenomenon. It is a visible mass consisting of cloud water droplets or ice crystals suspended in the air at or near the Earth’s surface. Fog can be considered a type of low-lying cloud, and is heavily influenced by nearby bodies of water, topography, wind conditions, and even human activities. In turn, fog has affected many human activities, such as shipping and transport, warfare, and culture.



Shadows are cast through fog in three dimensions. The fog is dense enough to be illuminated by light that passes through gaps in a structure or tree, but thin enough to let a large quantity of that light pass through to illuminate points further on. As a result, object shadows appear as “beams” oriented in a direction parallel to the light source.


There can actually be a loss or damping effect of high pitched sounds because they wouldn’t travel as far as they might when not being refracted off of separated water molecules which make up the consistency of fog. In contrast, low pitched notes, with a low frequency and a big wavelength, are moving the air less fast and less often, so the losses are reduced. Therefore, low-pitched notes are less affected by fog and will also travel further, thus the low pitched tone of a foghorn.


The foggiest place in the world is Hamilton, New Zealand, followed closely by the Grand Banks off the coast of Newfoundland, the meeting place of the cold Labrador Current from the north and the much warmer Gulf Stream from the south. Even in generally warmer southern Europe, thick fog and localised fog is often found in lowlands and valleys, such as the lower part of the Po Valley (i.e. Ravenna).
