Climagrams

Climagrams show the distributions of area average anomalies for broad-scale indices (e.g. sea temperatures across a region, teleconnection indices, standard 'monsoon' indices, etc.).  They are produced for a number of defined areas across the globe (Fig.8.3.4.2-1, Fig.8.3.4.2-2).

The seasonal (SEAS5) forecast of the anomaly (purple) lies well lies well above above upper terciles of the seasonal model climatologies (yellow and grey). .

Red dots are verification values from observations.

• in September to November below the mean but within the lower terciles of the seasonal model climatologies (yellow and grey).
• in January and February above the mean but rising above upper terciles of the seasonal model climatologies (yellow and grey).

 Red dots are verification values from observations.
