Abstract
The image for the Metarera XV area shows the 12-hour forecast of the pressure fields at mean sea level and thicknesses of 1000-500 hPa, obtained from the GFS model with a resolution of 0.5 x 0.5o degrees and plotted with the GraDS tool. Added to the above is the analysis provided by a professional who draws the predicted frontal systems for that period. The values of the pressure isolines are drawn every 4 hPa and that of the thicknesses every 60 geopotential meters.
