项目摘要

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

这项研究的目的是收集和数字化的气象参数，如降雨量的数据，在过去的三十年，已积累的印度尼西亚气象和地球物理局（BMG）作为手写或打字记录，并在对连续性和可靠性进行效用检查后建立一个有用的数据库，以填补印度尼西亚海洋大陆气候学的空白。在第一个财政年度（1996年），调查人员访问了BMG的中心办公室和10个地区办公室，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。在技术评估和应用局达成了一项关于合作收集和分析数据的执行协议。本文收集了160个测站30年（1961- 1990）的日降雨量资料，并将其数字化。 ...更多信息在BPPT、万隆技术研究所（ITB）、京都大学、东京大学等进行。在第二个财政年度（1997年），用原始记录或其他记录补充或纠正了前一年建立的数据库中缺少的和不确定的数据。其他时期（1961年之前和1990年之后）的数据，其他参数（每小时降雨量、地面气压和温度等）此外，缔约方还在其他地点（包括非BMG电台）收集了数据，特别是在西爪哇省和西苏门答腊省。所有资料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等机构的反演人员一起进行分析。E1 Nino年降水的延迟和减少以及前几年降水的增加的统计描述;降水年际变化与季节内和赤道波动变化活动之间的相关性;等等。
