Explanation:
The weather maps in the newspapers can be very simple or more complicated, depending on what should be depicted on it. In general, these maps almost always include isobars, which provide information about the air pressure. The symbols about the fronts are also often included, as they show what kind of air masses are active or will be active in the area. The symbols for precipitation always get included because they are one of the primary interest of the people, as well as providing information about the type of precipitation and its amount.
