As the national meteorological and climatological service MeteoSwiss has the mandate to provide weather and climate services for the safety and benefit of Switzerland. Being one of the founding members of ECMWF in 1975, Switzerland benefits from global medium-range weather forecasts and climate reanalysis since the beginnings of ECMWF. However, the country’s complex orography and local weather phenomena in the Alps impose a special challenge in providing accurate and timely local weather and climate information across scales.

In this talk I will present examples of seamless weather and climate services tackling the challenges imposed by complex orography. An emphasis will be laid on products arising from European collaboration in particular with ECMWF and EUMETSAT, but also examples of in-house developments of climate datasets. Some of the latest developments concern seamless workflows for weather and climate monitoring, wind climatology and the provision of a national drought platform as well as satellite applications.
