== Notes on NCEP trajectories == Ver 1.0 2005/01/12 by Nishi * NCEP dataset does not include vertical wind above 100hPa; please do not believe the results for NCEP kinematic trajectory which passes above 100hPa. My recommendation is that we do not see NCEP kinematic results except for limited special cases. * NCEP forecast is limited for 0 - 180 hours from analysis time. So, for the trajectories starting on the day and the next day of report (Day0 and Day1: If 07Jan, starting at 00Z on 07 and 08Jan) do not have 7-day length. The length is 6-day and 23-hours for Day0 starting and 5-days and 23-hours for Day1 starting). Please be careful for evaluating long trajectories. ECMWF trajectories do not have such a problem of forecast length.
