Meteorology · Fronts — Cold vs Warm Front Speed
Compared with warm fronts, cold fronts generally:
- AMove faster and have a steeper slope, producing narrower bands of more intense weather✓ Correct
- BMove slower with gentle, prolonged rain
- CNever produce any cloud
- DBring warmer air behind them
Explanation
Cold fronts advance faster and have a steeper frontal slope, lifting warm air abruptly to give a narrow zone of showers or thunderstorms followed by quick clearing. Warm fronts slope gently and move slower, giving a broad area of layered cloud and steadier, longer-lasting precipitation ahead of them.
