Utilization of wind steadiness index for identification of malaysian northeast monsoon onset and withdrawal from 2011 to 2015

Research output: Contribution to journalArticle

Abstract

The onset and withdrawal of the Northeast Monsoon over Malaysia is characterized by variability in its occurrence. This study uses the Wind Steadiness Index method, coupled with observations of accumulated precipitation, to determine the Northeast Monsoon onset and withdrawal dates. (Seasons in focus are from 2011/2012 to 2015/2016.) Then, further calculations are conducted to determine each season’s duration and other average values covering the period of study. For the temporal scope of this study, the earliest onset date is 14 October while the latest onset is 16 November. (Average onset is identified as 24 October.) On the other hand, the earliest withdrawal date is 9 February, while the latest withdrawal is 15 April. (Average withdrawal is identified as 18 March.) Finally, the calculated average duration is 114.2 days. In essence, occurrence of the Northeast Monsoon over Malaysia shows considerable variability, for the relatively short period covered in this study.
