1800 individuals, 18 countries, 10 years: Since 2002, the meteorologists at Freie Universität Berlin have been selling weather sponsorships for European high and low pressure systems, all for a good cause. Anyone who wishes to become a successor of Yvonne – the first female name to be used in 2002 – or who wishes to give someone a unique Christmas present, supports the continued weather observation by students at the Institute of Meteorology. In 2013 the high pressure systems will be given female names and the low pressure systems will be given male names. The prices are 299 euros for highs and 199 euros for lows.
This meteorological observation series has been running for more than 100 years and is one of the world's longest weather observation series. The names are awarded in the order of requests received. Meteorologists at Freie Universität’s Institute of Meteorology have been naming highs and lows in the Berlin weather area since 1954. In 2002 they opened up the naming process to anyone as part of the Adopt a Vortex program.
