Rationale
Justification for indicator selection
Precipitation is a major component of the hydrological cycle. The amount and spatial distribution of European precipitation is strongly influenced by circulation. Most precipitation over Europe is connected with the advection of maritime air masses from the Atlantic and the Mediterranean. The combination of changes in the precipitation regime and increases in air temperature can lead to extreme hydrological evens such a flooding and droughts. Some systems or sectors, closely connected with the hydrological cycle, are very sensitive to the combined effects of higher temperatures and changed precipitation characteristics. Within limits and at a cost, adaptation to many of the impacts is possible. These options will be briefly mentioned in the individual indicator sections.
Homogenous time series of monthly precipitation data and interpolation and gridding methods enable analysis of various periods from 1901 on various temporal and spatial scales. However, differences between climate models for future precipitation projections indicate higher uncertainty for regional and seasonal results than for temperature projections and observed precipitation trends.

Policy context and targets
Context description
In April 2009 the European Commission presented a White Paper on the framework for adaptation policies and measures to reduce the European Union's vulnerability to the impacts of climate change. The aim is to increase the resilience to climate change of health, property and the productive functions of land, inter alia by improving the management of water resources and ecosystems. More knowledge is needed on climate impact and vulnerability but a considerable amount of information and research already exists which can be shared better through a proposed Clearing House Mechanism. The White Paper stresses the need to mainstream adaptation into existing and new EU policies. A number of Member States have already taken action and several have prepared national adaptation plans. The EU is also developing actions to enhance and finance adaptation in developing countries as part of a new post-2012 global climate agreement expected in Copenhagen (Dec. 2009).
