Describe the difference between cold fronts and warm fronts in detail and include examples.

Explanation:

1. A cold front takes place when the cold air pushes the warm air upside and itself occupies the lower most region. In other words, a cold front appears when cold air brings about replacement of warm air. On the contrary, a warm front takes place when warm air pushes cold air and tries to replace it.

2. Before the cold front passes, the temperature is warm, and while it passes, the temperature undergoes a sudden decrease, and after it passes, it keeps on decreasing steadily. On the contrary, before a warm front passes, the temperature is moderately cool, while it passes, the temperature rises steeply and after it passes, then the temperature initially rises and ceases to rise and attains equilibrium.

3. Before passing of the cold front, the air moves along with the south - south west direction, the wind speed is also high and gusty, and after it passes, it undergoes change in its direction to north west. On the contrary, before a warm front passes, the air moves along south - south east, while moving the speed varies and when it passes, the direction is along south west.
