Weather map motion. Two-dimensional streamlines based on wind speeds at various levels show areas of convergence and divergence in the wind field, which are helpful in determining the location of features within the wind pattern. A popular type of surface weather map is the surface weather analysis, which plots isobars to depict areas of high pressure and low pressure. Cloud codes are translated into symbols and plotted on these maps along with other meteorological data that are included in synoptic reports sent by professionally trained observers. The use of weather charts in a modern sense began in the middle portion of the
Fan chart (time series) this way, central banks that employ inflation targeting report to the general public not only the more likely forecasts of the inflation rate "but also its balance of risks"! The split normal density is completely characterized by three parameters, the mode, variance and skewness. Therefore, the fan chart ranges depend on these parameters only. and In a central bank that employs inflation targeting, the three moments of the inflation forecast distribution are determined as follows: Fan chart (time series) In time series analysis, a fan chart is a chart that joins a simple line chart for observed past data, by
