The Empirical Mode Decomposition (EMD) is applied here in two dimensions over the sphere to demonstrate its potential as a data-driven method of separating the different scales of spatial variability in a geophysical (climatological/meteorological) field. After a brief description of the basics of the EMD in 1 then 2 dimensions, the principles of its 5 application on the sphere are explained, in particular via the use of a zonal equal area partitioning. The EMD is first applied to a artificial… CONTINUE READING
