Typically the forecast reliability is enhanced when an MJO event is detected in the forecast initial conditions. However, the resolutions of ENS and Extended Range differ, and the high-resolution spectral representations within the ENS have to be smoothed to the lower resolution of the Extended Range.

*10-15 day forecast* A strong Pacific ridge will push into the polar circle, cutting the bottom polar vortex in half, sending cold air into Eastern USA, and opening a temporary window for cooler Europe! The Extended Range does not start from Day0 but uses the results at Day14 of the ENS forecast as a starting point.
The MJO is characterized by an eastward propagation of an area of more organised convection in the tropics, typically initiated over the Indian Ocean and is important as it can influence developments elsewhere on the globe (eg monsoon evolution, tropical cyclogenesis near the Americas, El Nino/La Nina development (ENSO), and affecting aspects of the synoptic pattern over higher northern and southern latitudes including the North Atlantic Oscillation (NAO).
