A weather map is a graphical representation of relevant meteorological information. The weather map that we see on a newspaper or on TV is quite different from a technical synoptic chart. The first one uses icons that help us to understand at a glance what is displayed on the map, as icons naturally evocate the objects they represent. The second one, a technical weather map, uses plotting symbols, which do not resemble the object they represent, making them understandable just for technicians or someone with the proper training. Anyhow, with very basic information, we are all able to interpret what appears on a weather map, being an abbreviated way to learn about the weather to expect. The main features in which us, as viewers or readers, should focus our attention when looking at a weather map are: the presence of Highs and Lows, fronts, areas of precipitation, pressure, wind and cloud cover.
