Abstract

This study examines the characteristics of ocean surface current patterns in the Sunda Strait using numerical model current data from Marine Copernicus during the period 2013 – 2023. The analysis was conducted to identify the direction and speed of currents in seasonal periods, namely the west season (December – January – February), transition season I (March – April – May), east season (June – July – August), and transition season II (September – October – November). Marine Copernicus model current data was verified against High Frequency (HF) Radar observation data using the statistical method of Pearson correlation coefficient (r) and Root Mean Square Error (RMSE), resulting in an r value of 0.77 and RMSE of 0.26 m/s, indicating a good level of accuracy. The results of the analysis show that in the west season, the dominant current heads northeast with an average speed of 0.5 – 1.0 m/s and a maximum of 1.5 – 2.0 m/s. In the first transitional season, the current flows to the northeast with an average speed of 0.75 – 1.25 m/s and a maximum of 1.5 – 2.0 m/s. In the east season, the dominant current flows to the southwest with an average speed of 1.25 – 1.75 m/s and a maximum of 1.5 – 2.0 m/s. In the second transitional season, the current flows irregularly towards the west and east, with an average speed of 1.0 – 1.5 m/s and a maximum of 1.5 – 2.0 m/s. These current patterns are influenced by monsoon winds, seabed topography, and coastal interactions, which impact navigation, fisheries, and marine ecosystems.

Abstract

Southern Bali, characterized by intensive development and aviation activities, requires accurate rainfall information due to the influence of tropical atmospheric dynamics. This study employs a regression model based on air temperature and humidity using climatological data from 2000–2023 to analyze rainfall patterns. The results show that air temperature has the highest Pearson correlation with rainfall (r = 0.75), followed by air humidity (r = 0.67). However, RMSE evaluation indicates that humidity provides more accurate predictions (183.09 mm) than temperature (190.40 mm). These findings emphasize that correlation does not always reflect prediction quality, as it only represents linear relationships, whereas RMSE directly assesses model accuracy. Physically, humidity plays a direct role in cloud formation and rainfall, while temperature only regulates the atmosphere’s capacity to hold water vapor. Despite limitations during seasonal transition periods and extreme events, this model demonstrates potential to support data-driven rainfall prediction for risk mitigation, aviation meteorological services, and development planning in Southern Bali.

Abstract

This study aims to examine the characteristics of the West Monsoon wind based on convergence values at Sultan Hasanuddin International Airport, wind disturbance patterns over the Java Sea, the source and speed of air masses, regional-scale wind disturbances over Indonesia (Tropical Cyclones and Eddies), and wind flow patterns entering the study area under different rainfall categories during the period 2014 – 2023. The research employed a quantitative method by processing rainfall data and daily zonal (u) and meridional (v) wind component data during the peak rainy season (December – February). The analysis was conducted using the GrADS application to display streamline maps, data processing with Excel, and descriptive analysis. The results indicate that for the no-rain to light-rain categories, the characteristics of the West Monsoon wind are not clearly evident, except for wind disturbance patterns over the Java Sea and the speed and consistency of winds from the air-mass source toward the study area. In contrast, for moderate to very heavy or extreme rainfall categories, the characteristics of the West Monsoon wind are clearly observed. These conditions are characterized by air masses originating from the South China Sea, supported by strong and consistent wind speeds passing through the Karimata Strait and the Java Sea to Sultan Hasanuddin International Airport, as well as the presence of wind disturbances in the form of moderate to strong convergence over the Java Sea extending to the Makassar region. Therefore, the study concludes that the no-rain and light-rain categories exhibit nearly similar wind characteristics, while the main differences in the moderate to extreme rainfall categories lie in the consistency of wind speed and the intensity of convergence over the Java Sea.
