What do blue lines with triangles represent on a weather map and what would be the resulting weather?

Answer 1

Blue lines with triangles on a weather map represent cold fronts. A cold front occurs when a cold air mass moves into an area occupied by a warm air mass. The cold air pushes the warm air up, creating instability in the atmosphere and potentially leading to the formation of thunderstorms, heavy rain, or snow showers. The weather associated with a cold front can range from mild to severe, depending on the intensity of the front and other atmospheric conditions.
