forrest_andrew 0 Posted January 26, 2006 you lucky bugger (or maybe lots of dedication and many early mornings)!! either way, looks like you got a great display of the awesome light and amazing clouds that this place is known for. it is really an amazing place that i have told myself i must one day return to. your photo does it justice. good stuff!

02Pete 2 Posted January 27, 2006 Interesting photo of a lenticular cloud formation formed by mountain wave activity. Note not only the smooth, lens-shaped lenticular cloud, but also the rotor cloud (colored light to medium gray in this photo) formed at lower altitude upwind (closer to the mountains) in turbulent air. This type of cloud formation develops when strong, steady winds from a stable airmass blow directly across and are redirected upward by a mountain range, come back downward once on the other side of the mountain range, and repeat this cycle multiple times downwind of the mountain range, like a series of waves approaching a beach, or ripples in a brook downstream from a submerged rock. Air loses temperature as it gains altitude, and conversely gains temperature as it loses altitude. The lenticular cloud marks the range of altitude in which the smooth flow of air first cools to dewpoint as it ascends and water vapor in the air condenses to form a cloud on the upwind side, and then warms to evaporation point as it descends and dissipates on the downwind side. While the wind is continually blowing through, the cloud appears to remain stationary since it is constantly forming on one side and dissipating on the other. Generally, these clouds only develop in a stable airmass such as a cold-weather high pressure system, because the convective activity associated with an unstable airmass would disrupt their formation. Experienced pilots in oxygen-equipped sailplanes can ride the lift in the rising parts of mountain wave systems to considerable altitudes, but this sort of flying is not for the inexperienced as powerful rotor turbulence, powerful sinking air currents in the descending parts of the wave, the risk of increasing moisture in the airmass suddenly forming a solid cloud cover below a sailplane, and extreme cold at high altitudes, all require knowledge and skill to navigate safely. If you prefer the non-technical version, this photo mirrors the beauty and grandeur of nature. Link to comment

tomas kaspar 0 Posted January 27, 2006 Great shot, but I think that you can get more out of it. The foreground is too dark for me and even clouds could use longer exposure IMHO. It's a nice looking shot. Just a little adjustments. Link to comment
arnabbanerjee 0 Posted January 27, 2006 the foreground is dark and without details and without interesting features. With such interesting clouds in the sky, what about getting rid of the foreground altogether and give sky the deserved importance? Link to comment
