What is a good weather for air gliding?
i think good weather for air gliding is: there are well-formed cumulus humilis, with darker bases, suggests active thermals and light winds. active thermal means there is rising columns/bubbles of warm air. A bubble of air that is warmer than the surrounding air is less dense than the surrounding air and so weighs less than the same volume of that cooler, surrounding air. As it weighs less, the surrounding air pushes it up – and the bubble rises. The bubble will continue to rise until it is the same temperature as the surrounding air – when it weighs the same and so it is no longer pushed up. just like in this picture: http://upload.wikimedia.org/wikipedia/co… to analyze if the weather is good enough for air gliding.. this might be help: http://www.hart.wattle.id.
