    Projection of spatial and temporal changes of rainfall in Sarawak of Borneo Island using statistical downscaling of CMIP5 models
    (Elsevier, 2017) Zulfaqar Sa'adi; Shamsuddin Shahid; Eun-Sung Chung; Tarmizi bin Ismail
    This study assesses the possible changes in rainfall patterns of Sarawak in Borneo Island due to climate change through statistical downscaling of General Circulation Models (GCM) projections. Available in-situ observed rainfall data were used to downscale the future rainfall from ensembles of 20 GCMs of Coupled Model Intercomparison Project phase 5 (CMIP5) for four Representative Concentration Pathways (RCP) scenarios, namely, RCP2.6, RCP4.5, RCP6.0 and RCP8.5. Model Output Statistics (MOS) based downscaling models were developed using two data mining approaches known as Random Forest (RF) and Support Vector Machine (SVM).

    Trends analysis of rainfall and rainfall extremes in Sarawak, Malaysia using modified Mann-Kendall test
    (Springer, 2017) Zulfaqar Sa adi; Shamsuddin Shahid; Tarmizi Ismail; Eun-Sung Chung; Xiao-Jun Wang
    This study assesses the spatial pattern of changes in rainfall extremes of Sarawak in recent years (1980-2014). The Mann-Kendall (MK) test along with modified Mann-Kendall (m-MK) test, which can discriminate multi-scale variability of unidirectional trend, was used to analyze the changes at 31 stations.
