ENSO forecast: We expect El Nino will start evolving in late boreal spring and reach its height in the latter half of 2014.
Indian Ocean forecast: We find a bifurcation in the prediction plume. One is a neutral state in the tropical Indian Ocean; another is a weak positive IOD event starting in early boreal summer of 2014.
Regional forecast: In the Southern Hemisphere, as a seasonally averaged view, South Africa, western Australia, and eastern Brazil will experience colder-than-normal condition in the austral fall, while central Africa, eastern Australia, and a western part of the South American continent will be in a warmer-than-normal condition.
In the Northern Hemisphere, most part of Europe, Russia, China, Far East (including Japan), Canada, and U.S. will experience a warmer-than-normal condition in the boreal spring, while U.K., Middle East, and India will be in a slightly colder-than-normal condition. Southeast Asia (possibly related to possible evolution of El Nino), Japan, and West Africa will be in a drier-than-normal condition in the boreal spring, while precipitation over South Africa and Australia will be in a normal state as a seasonal average.
However, we must be careful about the above seasonal averaged view. In March, we expect a colder-than normal condition in the Far East. In Australia, we expect a rather wet condition in the western Australia in March but drier-than-normal condition in overall Australia, particularly in the northern part in April. Our skill to predict those intra-seasonal variations need to be improved more.
