"WebApr 5, 2024 · The colder the air, the denser the air becomes and thus the distance between any two height levels decreases. Conversely, warmer air is less dense, and, therefore, the distance between any two height levels increases. Because of this, thickness charts are used to help identify fronts and boundaries between air masses. " - Boundaries between air masses

Boundaries between air masses

WebOf course, the boundaries that separate contrasting air masses are called fronts, which leads us to the following conclusion: fronts lie in troughs of low pressure. Now, not all surface troughs coincide with fronts, but the bottom line is that fronts naturally exist in elongated regions of low pressure (troughs). WebA warm front is a boundary between an advancing warm air mass and a retreating cold air mass. Red half circles point in the direction of motion. Warm air rises over cold air at a slant, which leads to gradual lift. Stratus, altostratus, and cirrus are associated with warm fronts. Bird’s-eye View Colder air. Warmer air Side View
