Origin and fate of atmospheric moisture over continents

Very interesting presentation of Hubert Savenije (Delft University of Technology, The Netherlands) at the 2012 General Assembly of the European Geosciences Union. It is very fascinating research showing how much rain on land stems from the recycling of water on land (“precipitation recycling”) – and that is partially huge! Combine this with the “flying rivers” from Antonio Nobre (and others) and the biotic pump from Anastassia Makarieva (and others) – and its a perfect set for nature doing its best to develop and maintain perfect growing conditions for itself (see Gaia hypothesis of James Lovelock and Lynn Margulis).

On the first graphic from their paper, one can see how much of the precipitation falling on land stems from evapotranspiration from land. On the second one can see how much a region participates through evapotranspiration to the precipitations somewhere else.
