Association of global weather patterns with intraseasonal oceanic Kelvin waves coupled to atmospheric convection

Kelvin waves in the Pacific ocean have been associated with the Madden Julian Oscillation. These waves interact with the El Niño/Southern Oscillation (ENSO). A few of these waves apparently couple to atmospheric convection thereby allowing them to interact actively with the global atmospheric flow. This presentation describes the composite global flow associated with 19 such Kelvin wave events during El Niño and the northern hemisphere fall and winter. A large portion of the global response pattern associated with these events is distinguishable from the response patterns to the MJO and ENSO, and may be useful for long range prediction of mid latitude weather.
