MeteoSvizzera

MeteoSwiss played an instrumental role in the planning and conduction of the Mesoscale Alpine Programme (MAP). This large international project was the first Research and Development program (RDP) of the World Weather Research Programme (WWRP) of WMO and aimed at investigating atmospheric processes over a major mountain chain: the ALPS.

Scientific projects of MAP

Eight scientific themes were investigated during MAP. These are

Orographic precipitation

Incident Upper-Tropospheric anomalies

Gravity wave braking

Hydrological processes

Gap flows

Foehn in the Rhine Valley (FORM)

Gravity Waves

PV banners

Boundary layers in complex terrain

MAP: an instrumental success

During the decade 1995-2005 the MAP initiative provided an important motor for mountain meteorology and weather research. Four years of detailed planning (phase A) led to a broad field campaign over the European Alps during autumn 1999, the MAP special observing period (SOP or phase B). During the following years a large variety of studies synthesized the data collected during the SOP and used their findings for further research (phase C). While a number of solicited presentations at the ICAM-MAP conference highlight the scientific achievements made during the conduct of MAP, it is outlined here to how the overall success of MAP may be measured and which facets were conducive to it. It is assumed that some generalities can be distilled which may provide useful guidelines for future enterprises of a similar scope.

MAP D-PHASE

The fourth and last phase of MAP was a Forecast Demonstration Project and is called MAP D-PHASE. This project aimed at demonstrating the benefits MAP brought for forecasting high impact weather in the Alps. As specific theme heavy precipitation and associated flooding events were chosen. The D-PHASE Operations Period (DOP) has been in summer/ fall 2007.
