Sunset, South Monticello Area, Elephant Butte Lake State Park, Elephant Butte NM, April 15, 2009
My new Panasonic FZ28 camera's first sunset was a beaut too
I played with my new camera off and on all day yesterday trying to find my way through its extensive settings with the help of a pretty useless and confusing operators manual. At least the menu system on this camera is a little more intuitive than the one in my old Canon - maybe I stand a fighting chance of getting control over this one. Then I topped the day off with a bunch of sunset pictures.
Is that a virga I see below that cloud?
Maybe that accounts for some of the gusty winds we had here most of the day yesterday. Wikipedia describes a virga as:
In meteorology, virga is an observable streak or shaft of precipitation that falls from a cloud but evaporates before reaching the ground. At high altitudes the precipitation falls mainly as ice crystals before melting and finally evaporating; this is usually due to compressional heating, because the air pressure increases closer to the ground. It is very common in the desert and in temperate climates. It is also common in the Southern United States during summer.
Virga can cause very interesting weather effects, because as rain is changed from liquid to vapor form, it removes heat from the air due to the high heat of vaporization of water. In some instances, these pockets of colder air can descend rapidly, creating a dry microburst which can be extremely hazardous to aviation. Conversely, precipitation evaporating at high altitude can compressionally heat as it falls, and result in a gusty downburst which may substantially and rapidly warm the surface temperature. This fairly rare phenomenon, a heat burst, also tends to be of exceedingly dry air.

Wind on the Gangplank
There was almost no soil in that part of the range - just twelve miles' breadth of rough pink rock. "As you go from Chicago west, soil diminishes in thickness and fertility, and when you get to the gangplank and up here on top of the Laramie Range there is virtually none," Love said. "It's had ten million years to develop, and there's none. Why? Wind - that's why. The wind blows away everything smaller than gravel."
Standing in that wind was like standing in river rapids. It was a wind embellished with gusts, but, over all, it was primordially steady: a consistent southwest wind, which had been blowing that way not just through human history but in every age since the creation of the mountains - a record written clearly in wind - scored rock. Trees were widely scattered up there and, where they existed, appeared to be rooted in the rock itself. Their crowns looked like umbrellas that had been turned inside out and were streaming off the trunks downwind. "Wind erosion has tremendous significance in this part of the Rocky Mountain region," Love said, "Even down in Laramie, the trees are tilted. Old-timers used to say that a Wyoming wind gauge was an anvil on a length of chain. When the land was surveyed, the surveyors couldn't keep their tripods steady. They had to work by night or near sunrise. People went insane because of the wind." His mother, in her 1905 journal, said that Old Hanley, passing by the Twin Creek school, would disrupt lessons by making some excuse to step inside and light his pipe. She also described a man who was evidently losing to the wind his struggle to build a cabin:
