Abstract:
The goal of this study was to analyze the daily dynamics of air temperature and humidity patterns, as well as their correlative relationship, at various distances from the shoreline of Lake Tondano. This analysis aimed to provide a comprehensive scientific overview of the region's microclimatic conditions. Simultaneous air temperature and humidity measurements were taken every 30 minutes from 6:00 a.m. to 6:00 p.m. WITA using a 4-in-1 sensor at three observation points located 0, 50, and 100 m from the lake's edge. The primary param investigated were air temperature and relative humidity. Pearson correlation analysis was employed to quantify their interrelationship. Key findings revealed a strong, consistent negative correlation between air temperature and relative humidity across all three observation points. Pearson correlation coefficients (r) were -0.80 at 0 m, -0.97 at 50 m, and -0.94 at 100 m, indicating that the very strength of this inverse relationship intensifies with increasing distance from the shoreline. This phenomenon aligns with atmospheric thermodynamic principles: an increase in air temperature enhances its capacity to hold water vapor, leading to a decrease in relative humidity if the absolute water vapor content remains constant. The coefficient of determination (R²) further indicated that 58% to 81% of the variation in relative humidity could be explained by fluctuations in air temperature. In conclusion, the study found that air temperature is the main factor influencing humidity conditions.
