The drier the gas, the a lot more easily it will certainly melt. Real-time gas consist of moisture that is controlled by the plants' physiology as well as the amount of recent rains.
This is since the radiation and also convection a fires creates preheat the gas resource, and also this is much extra easily done upslope than down.
