The state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc.
Crepuscular rays or Sun rays 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 or between other objects, are columns of sunlit air. 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).
What to do when your power is out? I stepped outside and enjoyed this very nice complete rainbow out my front door! It was a real nice one too. Lasted a good 20 minutes and only faded with the sunlight. I hope those of you in the DFW area were able to see one. Apparently there were a bunch across the region this afternoon as several lines of thunder showers moved through. Here’s a few shots of the one I saw.
On February 24, 2007 a massive west Texas dust storm blew into north central Texas. These images show the extent of the dust in the atmosphere. Drivers had to use their headlights in the afternoon. Folks with breathing problems were warned to stay indoors, etc. The storm left a layer of dust on everything. Note the during and after shot below.
