Abstract:

The data for this research is compiled from the records of hourly rainfall between 1993 to 2014 which was generated from several. Automatic Rainfall Stations namely; Ayong-Bumbung Climatology Station, Sangkub-Huntuk climatology station, and Sangkub-Pangkusa Climatology Station. The data was then analysed using statistical methods. Rainfall distribution pattern is based on heavy rainfall recorded by automatic rainfall measuring device. The rainfall data used here are the ones with rainfall depth of more than 50mm. All the data are then analysed to obtain the frequency of occurrence of each of the rainfall duration. From the result of frequency analysis, it is then determined that certain rainfall duration represents the general rainfall condition in the research area. Research will show that rainfall pattern on the Northern Coast of Bolaang Mongondow, for heavy storm have a tendency of 7 hour duration, with 22% distribution for the first hour, 28% distribution for the second hour, 19% distribution for the third hour, 15% for the fourth hour, 7% for the fifth hour, 6% for the sixth hour, and 3% for the seventh hour.
