Hot Air Balloon Diagram
The Hot Air Balloon diagram below shows the main components of a typical hot air balloon. Some manufacturers install rapid deflation systems into their balloons which are generally variations to the rigging of the parachute vent panel shown in this example.

Mountain Waves formation
Airflow over a ridge or mountain range may set up an undulating flow downstream provided certain preconditions are met. This undulating flow is called mountain waves and can be the source of strong turbulence, rotors and high vertical wind speeds. Mountain wave activity is often evidenced by lenticular clouds. For mountain waves to form the […]
Thunderstorms
Flight through or near thunderstorms should be avoided! For thunderstorms to be created there needs to be: Unstable or conditionally stable air through a considerable depth of the atmosphere; A lifting mechanism to trigger the instability, this could be provided by a front, high terrain, heating from below or convergence of air in a low […]
Sea Breezes and Land Breezes
Sea breezes are winds that are caused by the differential heating rates of land and sea. During the day the land heats up more rapidly than the sea because: land has a lower specific heat than water – it requires less heat to raise the temperature of 1 kilogram of earth by 1 degree than […]
