ground tactics is more complicated due to factors of terrain, environment, sustainability, and logistical factors.
A plane operating theatre is the same everywhere else in the world. Airspeed and temp doesn't matter as much for a plane as all planes are meant to go fast & drop ordinance wherever they operate. Air combat will operate the same as the pacific to the Baltics. The only limiting factor is the amount of airbases available for rearmament & refueling
Ground vehicles are still scriptable to environmental issues such as heat, terrain factors, combat range dictated due to environments. You can't expect a 60ton tank to move through a mountain, swamp or jungle environment due to the limiting factors associated with ground warfare.
>tl;dr
Air combat in a 3D space stays the same while ground unit in 2D space dictates more factors in deployment
You just can't move through a swamp as well as you can through air therefore air supremacy is literally godlike power
