Weather map

A weather map is a tool used to display information quickly showing the analysis of various meteorological quantities at various levels of the atmosphere. Maps utilizing isotherms show probable location of weather fronts. Isotach maps of the upper atmosphere show where the jet stream lies. Streamlines show areas of converging and diverging winds, particularly in the tropics. At the surface, the popular type of weather map is the surface weather analysis, which uses isobars to depict areas of high pressure and low pressure, as well as help locate weather fronts. Special weather maps in aviation show areas of icing and turbulence.
