مسابقه شرح پدیده - سری اول

[M!Zare 48037]

درود...باز هم تالار مکانیک و یک مسابقه جدید... بدین صورت که یک تصویری قرار داده میشه و دوستان در مورد علت آن توضیح میدهند....حتی میشه نظر بقیه رو هم به چالش کشید و از میان آنها جامع ترین پاسخ به عنوان برگزیده انتخاب میشه...

 

نظرتون در مورد تصویر زیر و علت وقوع آن چیست؟

[GBG10 2039]

شاید احتمالا چون هوای اطراف کوه بخاطر مجاورت با برف و یخ کوه سرد هست، کاهش دما و تراکم بخار هوا رخ داده در اون ناحیه،

Lenticular clouds, technically known as altocumulus standing lenticularis, are stationary lens-shaped clouds that form at high altitudes, normally aligned at right-angles to the wind direction.

Where stable moist air flows over a mountain or a range of mountains, a series of large-scale standing waves may form on the downwind side. Lenticular clouds sometimes form at the crests of these waves. Under certain conditions, long strings of lenticular clouds can form, creating a formation known as a wave cloud.

Power pilots tend to avoid flying near lenticular clouds because of the turbulence of the rotor systems that accompany them, but sailplane pilots actively seek them out. This is because the systems of atmospheric standing waves that cause "lennies" (as they are sometimes familiarly called) also involve large vertical air movements, and the precise location of the rising air mass is fairly easy to predict from the orientation of the clouds.

"Wave lift" of this kind is often very smooth and strong, and enables gliders to soar to remarkable altitudes and great distances. The current gliding world records for both distance (over 3,000km) and altitude (14,938m) were set using such lift.

Lenticular clouds have been mistaken for UFOs(or "visual cover" for UFOs) because these clouds have a characteristic lens appearance and smooth saucer-like shape.
