Explanation:

Weather maps show rainfall (precipitation), maximum and minimum temperatures, and maximum and minimum humidity. By following the legends and symbols you can see the conditions in each region.

Within that map, a red semicircle in a line represents the existence of a hot front. There is a pattern in making maps, where the hot fronts are represented by a red semicircle, while the cold fronts are represented by triangles.

Hot front is the front of a moving hot air mass. Cold air is relatively dense, and warm air tends to dominate it, producing a wide band of clouds and a light, persistent rain, and sometimes sparse fog.

A hot front is a transition zone where a mass of hot, humid air is replacing a mass of cold air. The hot fronts move from Ecuador to the poles. As hot air is less dense than cold air, the hot air mass rises above the cooler air mass and precipitation usually occurs.
