Surface Chart Analysis

All meteorological parameters are monitored constantly but, at predefined hours (every six hours starting at 00.00 Z), a thorough examination of these parameters at surface level is done in the form of a surface chart analysis.

All pertinent synoptic structures like weather fronts (cold, warm and occluded front), convergence lines, trough lines and areas with significant weather will be drawn on this chart.

The pressure field will be visualised through a pressure analysis by means of isobars (isobars are lines of equal pressure) and the determination of the different pressure centres.
