the warm air that wins the territory war by floating over the cold instead of crashing through it
means In meteorology, the boundary where an advancing mass of warm air rises gently over a retreating mass of cooler air, typically bringing gradual cloud buildup and steady rain.
from A compound of plain English bones: "warm," from Old English "wearm" (related across the Germanic family to German "warm"), and "front," from Latin "frons, frontis," meaning forehead or brow — the foremost edge of a thing. The military sense of "front" as a battle line came first, and weather science borrowed it: pioneering forecasters in the early 20th century, working in the aftermath of a great war, literally pictured colliding air masses as armies, and named the line of engagement a "front." So "warm front" carries a faint whiff of the trenches into the daily forecast.
