Optimising predictor domains for spatially coherent precipitation downscaling [PDF]

Hydrology and Earth System Sciences, 2013
Statistical downscaling is widely used to overcome the scale gap between predictors from numerical weather prediction models or global circulation models and predictands like local precipitation, required for example for medium-term operational forecasts

Nucleation pathway in coherent precipitation [PDF]

Philosophical Magazine, 2011
The non-classical nucleation pathway of coherent precipitates has been computed through the minimisation of the nucleation barrier in the composition (c) - size (R) space so that to predict the evolution of the nucleus composition. The generalized Gibbs model developed by Schmelzer et al.
