Welcome to Danby Weather Outlooks!
A location for quick and easy digestible Long Range Weather Outlooks
Sourced from real-time oceanic analysis
DWO utilizes the El Niño Southern Oscillation and the Dipole Mode Index to develop climatological outlooks.
The Dipole Mode Index (DMI) is measured as the sea surface temperature anomaly difference between the western and eastern region. This value is assessed in real-time in conjunction with the Pacific Ocean ENSO 1+2 region.

The Oceanic Nino Index (ONI). A larger focus is stressed on the 1+2 region as well as upwelling along the Chilean and Peruvian coasts to determine the future long range temperature/precipitation signal.
