WEATHER · FREEZING LEVEL
Freezing Level
The altitude where the air hits 0°C — the snow line. Low where cold reaches the ground, high over the tropics; the rain-versus-snow line and an aircraft-icing cue.
What it shows
The freezing level is the altitude where the air temperature hits 0°C — the height of the snow line. Below it precipitation tends to fall as rain, above it as snow; pilots read it for icing risk.
How to read it
It reads low — near the ground — where cold air has reached the surface, and climbs to several kilometres over warm tropical air. Watch it dive over winter storms and mountain ranges, drawing the line between a cold rain and a snowfall.
