GribStream

IFS Dispersão do ensemble 0.1°

Código GribStream: ifsenfospread0p1

IFS mean and spread: 00 and 12 UTC; 3h steps to 144h, then 6h steps to 360h
00 / 12 UTC · +0…144h: 3h · +150…360h: 6h This coverage reference was generated from for the ifsenfospread0p1 page; available variables may differ.

Desvio padrão calculado pelo fornecedor nas unidades físicas de cada campo. A dispersão de temperatura é uma diferença em kelvin: não subtraia 273.15.

Ciclos de 00 e 12 UTC. Passos de três horas de +0 a +144h, depois de seis horas de +150 a +360h.

Os dados de origem começam em 20 de outubro de 2026 às 12 UTC. Cada estatística tem seu próprio dataset sem dimensão de membro. Use os seletores exatos com runs ou timeseries.

    gh –Geopotential height (gpm)
    3 variants

    Parameter ID 156

    ECMWF param DB

    Height derived from geopotential divided by standard gravity (9.80665 m s-2).

    • Used on constant pressure levels to diagnose synoptic features (e.g., troughs, ridges, cyclones).
    • At the surface, it reflects orography (geopotential height of the surface).
    • A geopotential metre is approximately 2% shorter than a geometric metre.
    • This dataset contains ensemble standard deviation, not the mean. Temperature spread is a temperature difference in kelvin; do not subtract 273.15.

    msl –Mean sea level pressure (Pa)
    1 variant

    Parameter ID 151

    ECMWF param DB

    Atmospheric pressure adjusted to mean sea level, reflecting the weight of the air column.

    • Maps of mean sea level pressure highlight cyclones, anticyclones, and wind strength via contour spacing.
    • Often expressed in hPa or millibars (1 hPa = 1 mb = 100 Pa).
    • This dataset contains ensemble standard deviation, not the mean. Temperature spread is a temperature difference in kelvin; do not subtract 273.15.

    t –Temperature (K)
    3 variants

    Parameter ID 130

    ECMWF param DB

    Air temperature throughout the atmosphere.

    • Units are kelvin (K); to convert to degrees Celsius (deg C), subtract 273.15.
    • Available on multiple vertical levels.
    • This dataset contains ensemble standard deviation, not the mean. Temperature spread is a temperature difference in kelvin; do not subtract 273.15.

    ws –Wind speed (m s-1)
    2 variants

    Parameter ID 10

    ECMWF param DB

    Magnitude of wind velocity. The dataset determines whether this is the ensemble mean or standard deviation.

    • This dataset contains ensemble standard deviation, not the mean. Temperature spread is a temperature difference in kelvin; do not subtract 273.15.
