Crepuscular rays

From Wikipedia, the free encyclopedia:
Crepuscular rays (also known as sunbeams, Sun rays or God rays) in atmospheric optics, are rays of sunlight
that appear to radiate from the point in the sky where the sun is
located. These rays, which stream through gaps in clouds (particularly stratocumulus)
or between other objects, are columns of sunlit air separated by darker
cloud-shadowed regions. Despite seeming to converge at a point, the
rays are in fact near-parallel shafts of sunlight, and their apparent
convergence is a perspective effect (similar, for example, to the way
that parallel railway lines seem to converge at a point in the
distance).
The name comes from their frequent occurrences during twilight
hours (those around dawn and dusk), when the contrasts between light
and dark are the most obvious. Crepuscular comes from the Latin word
"crepusculum", meaning twilight.

Weather Forcast for South of Sweden
Do you think it will clear up in the afternoon?

Mats and Anna was forcasting the weather for the afternoon and tomorrow directly to their listeners with reporter Lina Nilsson.
- Well, the forcast for this day was almost correct..
The wind as usual in Karlskrona, windy.
Temperature moderate 15-17 degrees
But sparesome with sunshine in the sky though.
Stratus from the morning became mostly stratocumulus instead, that kept coming from the inland... NorthWesterly wind.
Smiles and sunshine from my Friends and Sunbeams on the
ground, and smalltalks with a lots of curious people instead.
An unusual high highpressure was notably for Mats and Anna today, not just because of the crowd that visited them, but also for in one of these days we passed a highpressure record at 1041 Hpa in south of Sweden.
