Impact of Madden-Julian Oscillation on the Diurnal Rainfall Cycle in Peninsular Malaysia
The study investigated the influence of the early phases of Madden-Julian Oscillation (MJO) on the diurnal rainfall cycle in Peninsular Malaysia (PM). The most significant variations in precipitation occurred late evening Malaysia Standard Time. The remote impacts of MJO on PM resulted in changes to...

description | The study investigated the influence of the early phases of Madden-Julian Oscillation (MJO) on the diurnal rainfall cycle in Peninsular Malaysia (PM). The most significant variations in precipitation occurred late evening Malaysia Standard Time. The remote impacts of MJO on PM resulted in changes to the diurnal rainfall patterns during the early MJO phases when the primary MJO convection centre remains over the Indian Ocean. These conditions created a conducive environment for local convection over PM due to the weakening of the southwest monsoon winds. Along the west coast of PM, intensified sea breeze led to anomalous moisture transport fuelling the local convection. In contrast, the eastern coast experienced drier weather due to opposing sea breeze and monsoonal wind patterns, diminishing moisture transport towards the northeastern coastal region. |
