  • Digital archive of the analyzes of the surface charts of 00 UTC and 12 UTC, held in IM and IPMA Weather Forecast Center since October 2015. In the surface analysis charts, the isobars are filled up every 5 hPa, the high pressure centers (A) and the low pressure centers (B). Frontal surfaces, crest lines, valley lines, lines of instability and convergence are represented according to the standards established by the WMO. This compilation is in digital format (pdf) with a total of 1094 charts.
