European Centre for Medium-Range Weather Forecasts (ECMWF) Storm Trajectories
Listed in NASA Earthdata CMR
This data set consists of 5 day back trajectories computed on a routine basis using analyses from the European Centre for Medium-Range Weather Forecasts (ECMWF).
Description
The trajectories are calculated at ECMWF using 6 hourly T106 operational analyses of the three components of the wind and surface pressure which are interpolated on to a 1.5 x 1.5 degree grid. The data are linearly interpolated in time and space.
The output data consist of latitude, longitude and pressure of the trajectory every 30 minutes. 1. 252 back trajectories which are launched at 900 mb from points on three regular latitude / longitude grids centred over the UK., the mid-Atlantic storm track region and the eastern U.S.A. The data set runs from 1979 to February 1999. The back trajectories were lauhnched at 12.00. In addition during 1996 and 1997, as part of the ACSOE campaign, the 12.00 releases were supplimented by releases at 00.00, 6.00, and 18.00. 2.

Clusters of back trajectories launched from pre-defined instrument sites in the UK - Weybourne (52.95N, 1.13E), Great Dunn Fell (54.68N, 357.55E), Bush Estate (55.50N, 356.80E), Aberystwyth (52.42N, 356.00E) Mace Head (53.32N, 350.10E) and in the Irish Sea west of Mace Head (53.00N, 346.00E). These trajectories are launched 4 times per day from 4 different pressure levels (700, 850, 950 and 1000 mb). The data set covers the period of the ACSOE campaign (1995-1997). 3.
Global back trajectories on a 20 by 36 lat-long grid - the grid is not regular in latitude. This grid is repeated on 9 pressure levels (approx 950, 850, 750, 650, 550, 450, 350, 250, 150 and 50 mb). This data set covers the period 1997-February 1999.
