LCS Analysis and Forecasts for 14 Aug 1200Z to 15 Aug 0000Z 2017, Issued 13 Aug 2017

The following figures show the FTLEs in the domain, at different times. These FTLE computations are for a time window of 6 or 24 hours for the forecast of 14 August 2017 to 15 August 2017. The window center shifts in 1 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.

As a reminder, 12:00Z = 08:00 EDT, i.e., local time is 4 hours behind Zulu time.
