The probabilities for the below, near or above normal tercile categories are shown for various lead times, ranging from months 1-7 for monthly forecast period and from quarter 1 to 5 for seasonnal forecast (next three month). Parameters displayed oare
- Land/Sea Temperature
- Maximum Temperature
- Minimum Temperature
- Temperature at 850hPa
- Zonal Wind at 850hPa
- Meridional Wind 850hpa
- Precipitation
- Sea Level Pressure
In each case, 6 maps are dispalyed for probilities :
- Probabilities for Below normal tercile
- Probabilities for Normal tercile
- Probabilities for Above normal tercile
- Probabilities for Highest Sextiles
- Probabilities for Lowest Sextiles
- Probabilities exceeding median
Anomalies maps and standard anomalies maps are also provided.
The probabilities (or chances) are generated from the Arpege Climate Systeme 5
