Fronts are transition zones between cool and warm air masses. The leading edge of a wedge of cold air represents the frontal zone. The front is called a cold front if the wedge is moving into an area of warmer air. If the wedge is retreating, the front is called a warm front with warmer air moving into an area previously occupied by cool air. Which weather condition is NOT associated with warm fronts?
a. warm fronts tend to move slowly
b. steady rise of temperature as front passes
c. warm fronts typically produce more violent weather than cold fronts
d. winds south-southeast before passing and south-southwest after passing

The warm front usually refers to the front that replaces the cold front and is characterized by the steady increase in temperature while passing the front, and the wind before passing the front move in a south-southeast direction and after passing the front, the wind moves in a south-southwest direction. This warm front moves at a very slow rate. This front is responsible for the occurrence of rain, with a fair wind.

In the given options, all are the characteristics of a warm front, except option (C), which is a characteristic of a cold front.

Cold front is usually responsible for the occurrence of violent weather patterns that includes severe and more violent thunderstorms.

Hence, the correct answer is option (C).
