亚洲夏季风是缅甸的主要气候系统，近90%的降水来自夏季风。季风开始的时间对农业部门和水的补充至关重要。然而，目前还缺乏系统的方法来检测缅甸的气候季风爆发日期。在这项研究中，使用1968年至2000年29个站的平均候降水数据定义了缅甸夏季风爆发的气候学。结果表明，缅甸南部和中部的季风爆发日期为5月18日（第28候的中间日期），缅甸北方的季风爆发日期为5月28日（第30候的中间日期）。通过检查4月21日至6月9日期间观测站数据和ERA40再分析数据的7个气象参数，确认了缅甸两个地区的气候开始日期。皇家气象学会
Asian summer monsoon is the predominant climate system in Myanmar and nearly 90% of total rainfalls are from summer monsoon. The timing of monsoon onset is of importance to the agricultural sector and water replenishment. However, there is a lack of systematic method to detect the climatological monsoon onset dates of Myanmar. In this study, the climatology of the summer monsoon onset over Myanmar is defined using the mean pentad precipitation data of 29 stations from 1968 to 2000. As a result, the climatological monsoon onset dates over Myanmar are on 18th May (the middle date of pentad number 28) in the southern and central Myanmar and on 28th May (the middle date of pentad number 30) in the northern Myanmar. These climatological onset dates in two areas of Myanmar are confirmed by examining seven meteorological parameters of the observed station data and ERA40 re‐analysis data during the period between 21st April and 9th June.
