The mix between a cold and a warm front is called, an occluded front. They are often shown as purple coloured. Mind you, from the origin of the synoptic map, there was no colour used! ;-)
There are two types of occlusions: a warm and a cold one. The warm one is when the cold front rises over the warm one. The cold occlusion is when the cold front lifts the warm one. It all depends on the temperature between the cold polar air ahead of the low pressure, and behind it.
On a weather map, what is a purple line with either dashed lines or triangles and circles represent?
I know that blue triangles represent a cold front, red circles represent a warm front, I think I've heard that the mix between a cold and warm front represents an arctic front, but I would like to know what a purple line with either a dashed line or triangles and circles represents.
