Analysis and Forecasts for 20 Jul 0000Z to 22 Jul 0000Z 2017, Issued 20 Jul 2017

The following figures show the FTLEs in the domain, at different times. These FTLE computations are for a time window of 1 day or 12 hours for the forecast of 20 Jul 2017 to 22 Jul 2017. The window center shifts in 6 hour intervals. The flow maps were calculated using a PDE based approach by using 5th order spatial and 3rd order temporal schemes, and a novel composition based approach.
