Analysis and Forecasts for 21 Jul 0000Z to 23 Jul 0000Z 2017, Issued 21 Jul 2017 (noon)
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 21 Jul 2017 to 23 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.
