Analisis Sebaran Suhu Permukaan Laut Dan Kaitannya Dengan Curah Hujan Di Kepulauan Mentawai
ABSTRACT
The Mentawai Islands, which are directly adjacent to the Indian Ocean and
located in the equator, make the Mentawai Islands area influenced by the
characteristics of the sea surface temperature of the Indian Ocean. The location
causes the area to have a climate with hot and humid air and high rainfall. This
study aims to determine the distribution of sea surface temperature, average
rainfall, and the relationship between sea surface temperature and rainfall in the
Mentawai Islands for 10 years (2012-2021). The method used in this research is a
survey method, namely direct observation at the research site. This research was
carried out in several stages, namely, measuring sea surface temperature in the
field, taking image data, collecting rainfall data, and analyzing data. The data used
in this study are NOAA Sea Surface Temperature data, and BMKG rainfall data.
The results of this study indicate that the sea surface temperature in the study area
in the wet month (October - March) ranges from 29.05 oC - 29.68 oC. In the wet
month, the maximum value of sea surface temperature occurs in February, which
is 29.68 oC. The minimum value of sea surface temperature occurs in November
and December, which is 29.05 oC. The sea surface temperature in the dry months
(April – September) ranges from 30.23 oC – 28.95 oC. In the dry month, the
maximum value of sea surface temperature occurs in April and May, which is
30.23 oC, while the minimum value of sea surface temperature occurs in August,
which is 28.95 oC. The maximum rainfall in the Mentawai Islands Regency occurs
in November with an average rainfall of 386 mm while the minimum rainfall
occurs in June with an average rainfall of 127 mm. The results of the correlation
analysis of sea surface temperature with rainfall in the wet month showed a
positive correlation. Meanwhile, in the dry month there is a negative correlation.
