Are the cloud and precipitation shield associated with a cold front wider than, narrower than, or the same as the cloud and precipitation shield associated with a warm front?
Narrower
What is a front?
A narrow zone of transition between air masses that contrast in temperature, vapor mixing ratio, and air density.

What type of front is formed when the leading edge of cold air merges with a warm front?
An occluded front
