In DEMOFLY_2 thermal flow had described in elementary mathematic and it amplitude had depended on altitude. The structure of thermal was permanent. So, you remarks concerning unreality of simulator coming from here. And an additionally a thermal core was so small for handling it by cycling; lifting zone and fly lower zone had clear circus forms.

In DEMOFLY_3 principally new model of thermal flows represented. Due to more complicated mathematic succeed to elaborate a thermal structure that depended on many parameters now:

- at a height less than 100 meters (328 feet) we got a "air boiling zone” (plural drizzle bubbles)

-- 100-400 meters (1312 feet), thermal core formation and birth of “fly lower zone”

-- 400-1200 meters (3937 feet), already formed thermal flow that has increasing diameter in depending on altitude.

-- 1400 - 1700 meters (5 577 feet) lower clouds edge, thermals decay

Needs to appear depend of thermal structure and thermal drift on strength of wind. At a height 600-1200 meters (3937 feet) compression of flows in direction from wind have a good visibility. It possible to look at detailed physical-mathematical model by download it here (less than 700 k)

The model has realized in the form of three-dimensional surfaces which are possible not only to see but to measure, and also to change it by one from five parameters in on-line.
