NRL Memorandum Report: Tropical Waves and Indonesia Flooding - Identifying Predictability Limits
Abstract
This document describes the role of the tropical equatorial waves in triggering the extreme weather events, namely floods in Indonesia. Itis shown that large precipitation in this region is usually related to the passage of the active phase of the equatorial disturbances such as MJO,Kelvin waves and Rossby waves. The mechanism of amplification of tropical convection through interaction with the oceanic equatorial wavesis investigated, indicating the atmosphere-ocean feedback loop. It is shown that while the dynamical models such as the Navy ESPC systemrepresent well the relationship between the waves and the extreme precipitation events, prediction of the equatorial waves, especially Kelvinwaves is more difficult.
