In this section we will discuss different product from the extended-range forecasts. We will discuss also the verification aspects and drivers of predictability.

• The extended forecasts are produced twice a week (Monday and Thursday). Forecasts are produced for the coming 46 days with focus on week to week changes in the weather.
• Forecasts are generally presented for the first 32 days in terms of anomalies relative to the climate
• The long forecast ranges are best used if presented as multi-days means (maximize the possibility to capture predictable signals)
• Other products are of value: potential tropical cyclone activity, MJO indices, potential Sudden Stratospheric Warming activity.

More details are available in the Forecast user guide.
