Volume enhances thermals

November 18, 2019

The strength of a thermal is determined not only by the temperature of a thermal bubble, but also by its volume. The larger the volume, the stronger the buoyancy. This works according to the same principle, according to which container ships with increasing size can also carry more containers and thus weight. If two separate ascending beards flow together at a height, they will together have a significantly larger volume. The buoyancy intensifies. This can be one of the triggers why beards under clouds sometimes grow vigorously. It is then not the cloud that "pulls", but the thermals, which thanks to the gain in volume push more towards the cloud. Unfortunately, such practical meteorological knowledge is often neglected in classical education. But here can be helped. Lu-Glidz offers under the title Lu-Academy on request lectures and workshops for clubs and other pilot groups. Recently, I was among others among the Black Forest vultures in Karlsruhe. On their website a bold summary of the evening has been published. If you ask yourself to what extent a Lu Academy actually adds value, you can get a first impression there.
