Thermal trigger
A place where warmed air breaks away from the ground and starts to rise, such as a forest edge, field boundary or terrain break.
Also known as
- trigger point standard term
Terms and slang labels apply to this language. Usage may differ in other languages.
What it means
A trigger is not the same as a thermal source: the source is the surface that heats the air, the trigger is where that air separates from it. Triggers are typically boundaries between surfaces or breaks in the terrain.
Example in context
Nothing was working over the field, so I headed for the forest edge, a classic thermal trigger.
