I have captured these detailed images of the fog drops that we have in the Urgell region for The Readers’ Photos of La Vanguardia. I used a Canon 400d camera and 18-55 mm lens.
In the absence of raindrops it seems that we should be content with those of fog, but this is no consolation in the face of the persistent drought.
Fog refers to the suspension of small water droplets that produce visibility of less than 1 km. It is a meteorological phenomenon that consists of very low clouds, near or at ground level and formed by small volume water particles in suspension.
According to the World Meteorological Organization, deposits of fog droplets “are especially observed in high areas where orographic clouds are frequent.”
The extent or depth of the deposits depends on the duration of the fog, the size distribution and number density of the fog (or cloud) droplets, as well as the impact velocity of the droplets.
They also depend on the properties of the object, often a leaf, on which the deposit is formed, as in this case in these snapshots captured in Urgell.
When a large deposit occurs, the deposited droplets collect and drip onto the ground. In some circumstances, “the amount of water falling from trees in this way in a single night may be equivalent to the precipitation of a moderate rain shower.”
