Question 783Navigation General

The correct answer is B) cold front. A cold front is a type of weather front where a mass of cold air replaces a mass of warm air, often accompanied by a series of brief showers and strong, shifting winds. This is because the leading edge of the cold air mass causes the warm air ahead of it to rise rapidly, leading to the formation of clouds and precipitation. The other options are incorrect because: A) Cyclones are large-scale low-pressure systems, not associated with the specific weather phenomena described. C) Upper fronts aloft refer to frontal systems in the upper atmosphere, not at the surface. D) Occluded fronts form when a warm front and a cold front merge, and do not necessarily produce the weather conditions described.
