Climatology of Indonesian Maritime Continent

这项研究的目的是收集和数字化Indoneshian气象和地球物理机构(BMG)近30年来积累的手写或打字记录的气象参数数据，并在对连续性和可靠性进行实用检查后产生一个有用的数据库，以填补印度尼西亚海洋大陆的气候空白。在第一个财政年度(1996)，调查人员访问了BMG的中心办公室和10个地区办事处，并调查了业务观测的状况(仪器精度、连续性、记录方法等)。在每个办公室。在技术评估和应用机构(BPPT)达成了关于协作数据收集和分析的执行协议。收集了160个测站30年(1961-1990年)的日降雨量数据，并根据BMG中心办公室提供的数据进行了数字化处理，对数据实用程序…进行了初步调查在BPPT、万隆工业技术研究所(ITB)、京都大学、东京大学等进行了更多的工作。在第二个财政年度(1997年)，对前一年建立的数据库中缺少的和不确定的数据进行了原始或其他记录的补充或更正。其他时期(1961年前和1990年后)、其他参数(每小时降雨量、地面气压和温度等)的数据。和其他地点(包括非BMG车站)也被派对收集，特别是在西贾瓦和西苏门答腊省。所有数据都安装在京都大学和北京邮电大学的计算机上，并与东京大学、ITB等其他机构的逆变器一起进行分析。分析数据库的初步结果如下：基于平均降雨季节变化的气候学；雨季的开始和退出及其与卫星观测到的云活动的差异；关于厄尔尼诺年降水延迟和减少以及未来几年降水增加的统计描述；降水年际变化与季节内和赤道波动变化活动的相关性等

The objective of this study is to collect and digitalize data of meteorological parameters such as rainfall for last three decades which have been accumulated by the Indoneshian Meteorogical and Geophysical Agency (BMG) as hand-or type-writing records, and to produce a useful database after utility checks on continuity and reliability which should fulfilll climatological blanks over the Indonesian maritime continent.In the first fiscal year (1996), investigators visited the central office and ten regional offices of BMG,and surveyed the status of operational observations (instrumental accuracy, continuity, recording method, etc.) at each offices. An implementing agreement on collaborative data collection and analysis was made at the Agency for Assessment and Application of Techonology (BPPT). Daily rainfall data at 160 stations for a period of thirty yeas (1961-90) were collected and digitalized from data available at the central office of BMG.Preliminary investigations on data utility … More were carried out at BPPT,Bandung Institute of Tecnology (ITB), Kyoto University, University of Tokyo, etc.In the second fiscal year (1997), lacked and uncertain Data included in the database constructed in the previous year were supplemented or corrected by original or other records. data for other periods (before 1961 and after 1990), other parameters (hourly rainfall, surface pressure and temperature, etc.) and other locations (including non-BMG stations) were also party collected, in particular in West Jawa and West Sumatera Privinces. All the data were installed on computers at Kyoto University and BPPT,and analyzed together with inversigators of other institutions such as University of Tokyo, ITB,etc.Early results obtained from analysis of the database are as follows : climatology based on mean seasonal variations of rainfall ; onset and withdrawl of rainy season and their differences from cloud activities as seen by satellite observations ; statistical descriptions on delay and decrease of rainfall in E1 Nino years, and on increase in each preceeding years ; correlations between interannual rainfall variations and activities of intraseasonal and equatorial-wavelike variations ; etc. Less
