climatic variability High-temporal resolution pollen west Mediterranean
2009/12/3
High-temporal resolution pollen record from the Alboran Sea ODP Site 976, pollen-based quantitative climate reconstruction and biomisation show that changes of Mediterranean vegetation have been clear...
Using adjoint sensitivity as a local structure function in variational data assimilation
adjoint sensitivity local structure function variational data assimilation
2009/11/12
One approach recently proposed in order to improve the forecast of weather events, such as cyclogenesis, is to increase the number of observations in areas depending on the flow configuration. These a...
Nonlinear dimensionality reduction in climate data
Nonlinear dimensionality reduction climate data
2009/11/11
Linear methods of dimensionality reduction are useful tools for handling and interpreting high dimensional data. However, the cumulative variance explained by each of the subspaces in which the data s...
Long-term predictability of mean daily temperature data
Long-term predictability mean daily temperature data
2009/11/9
We quantify the long-term predictability of global mean daily temperature data by means of the Rényi entropy of second order K2. We are interested in the yearly amplitude fluctuations of the temperatu...
