A new temporal interpolation method for high-frequency vector wind fields

A new technique for the time interpolation of the forcing fields that recovers the movement of propagating features is introduced and applied to vector wind fields. The method involves the decomposition of the fields into their complex empirical orthogonal functions, and the interpolation of the temporal functions for the significant modes. The technique is tested using atmospheric model vector wind fields sampled at coarse temporal resolution to demonstrate the recovery of the wind fields at the intermediate times. The technique is also applied to a gridded vector wind product from satellite scatterometer data.
