Set V - Seasonal 7-month forecast (SEAS)

Order real-time forecasts

SEAS comprises ensembles of individual forecasts coupled to an ocean model and post-processed products of average conditions (e.g. monthly averages) with the associated uncertainty. Products are available up to 7 months ahead.

The following sub-sets are available:

V-i: Monthly means of ensemble means

Field computed from data of the daily individual forecast runs (section V-v) and averaged over all ensemble members. The fields are provided in GRIB code.

V-ii: Monthly mean anomalies of ensemble means

V-iii: Monthly means of individual ensemble members

V-iv: Monthly mean anomalies of individual ensemble members

V-v: Individual forecast runs

Definition of the monthly fields

The definition of the month is in accordance to the calendar month of the western calendar

  • Monthly means are computed using values at write-up times 00, 06, 12 and 18 UTC for
    • 2m temperature (K)
    • 10m U-velocity (m/s)
    • 10m V-velocity (m/s)
    • MSLP (Pa)
  • Monthly means are computed using values at write-up times 00 and 12 UTC for
    • Pressure-level parameters
  • Monthly means are computed using values at the write-up time 00 for
    • Sea surface temperature (K)
    • Soil temperature level 1 (K)
    • Volumetric soil water layer 1 (m**3 m**-3)
  • Monthly mean total precipitation (m/s) is the rate of precipitation during the month.
  • Maximum temperature at 2 meters (K) is the monthly mean of the maximum of MX2T (Maximum temperature at 2 meter since last post-processing).
  • Minimum temperature at 2 meters (K) is the monthly mean of the minimum of MN2T (Minimum temperature at 2 meters since last post-processing).
