As an alternative, the principle driver of the warming development is the event of excessive stress over and close to the UK.
As this high-pressure strengthens, it causes sinking air within the ambiance. This descending air is compressed because it strikes downward, resulting in warming via a course of referred to as adiabatic compression.
In easy phrases, as air is compressed, its temperature will increase. This course of can considerably elevate floor temperatures, even when the unique air mass will not be particularly heat.
