Warmer and less
Colder and less
A cold front is more severe because it is steeper.
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
Prior to a Thunderstorm, the temperature can range anywhere from 60 to 90 degrees F but the humidity and dewpoint will be very high. As the Thunderstorm releases rain, the temperature will decrease. It brings cold air down from the top of the Thunderstorm.
thunderstorm
cold air.
A weather front occurs when two currents of air with different densities converge. The rising of the less dense warm air above the denser cold air causes a mass of clouds to form. On the weather reports, they often show a cold front as a blue line and a warm front as a red line.
Severe thunderstorms often form along cold fronts, though not always.
A cold front is more severe because it is steeper.
cold
A cold object is more dense.
Cold and dense
Thunderstorm downdrafts are cold because the air has been cooled by rain. The cooled air then sinks as it has become denser than the surrounding air.
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
the warm air is pushed down because its lees dense than the cold air if cold air is more dense.
A cold front advancing
When dense,cold air meets less dense,warmer air, the warm air is pushed up
When dense,cold air meets less dense,warmer air, the warm air is pushed up
