The following example impressively demonstrates the capabilities of the barograph ‘Meteograf’, showing how it recorded the storms that swept over central Europe during the Christmas holiday of 1999.
 

• In Switzerland, the deep depression "Kurt" generated storm-strength winds on Saturday December 25^th, causing some limited, localized damage
• This was followed on Sunday December 26^th by the hurricane "Lothar".  Wind speeds of over 200 km/h were recorded.  Unprecedented devastation was caused all over Switzerland, with thousands of buildings, boats, etc. being wrecked and an estimated million trees being uprooted.
• Further damage was left by the depression "Martin", which passed over Switzerland on Tuesday December 28th.

The barograph, ‘Meteograf’s storm warning function gave, in each of the three cases above, a warning several hours before the storm hit.

The ‘Meteograph‘ is also available with a PC-Interface. the barometric pressure data recorded over the last ten days is stored. Her an example of the recordeing of the last 5 days:
