Recently, a new method has been proposed by Ray Schmitt (WHOI) and collaborators to use salinity patterns in the ocean to predict weather events (more specifically, rainfall) at scales from weeks to months. First, they were able to predict rainfall in the Sahara region. More recently, they have expanded their methodology to predict weather in the US and their method performed better than most of the traditional approaches (that included patterns like El Niño).
- can we expect to have a better global seasonal rainfall prediction in the near future as they described?
- What are the limitations of the approach?
- How far in the future can we extend the approach?
