Abstract

The temperature in sea water varies at each depth. The temperature of sea water at the surface is higher and the temperature at a deeper point is decreasing slowly. This study aims to determine the model of the temporal, spatial function, and dynamic models of daily temperature gradients above sea level and in sea water. This type of research is included in the type of exploratory research that is quantitative in nature. The research is in Tulaun hamlet, Lalumpe Village, Kombi District, Minahasa Regency, North Sulawesi Province, Indonesia. The research was conducted for 24 hours at 9 points, ranging from 0 cm, 10 cm, 30 cm, 60 cm, 100 cm, 150 cm, 220 cm, 300cm, to 400cm. The research variables were temperature and light intensity. Data processing in this study is to enter existing data into the Matlab application. The results of the study of changes in the functional model above sea level and in seawater are influenced by the heat absorption process of air temperature.

Abstract

This study aims to determine the temporal function model, spatial temperature and dynamic models of air temperature gradients over the surface of open land, vegetated land, and asphalt surface. The research location is at the State University of Manado in the hills of Tonsaru South Tondano, Minahasa Regency. The research methodology was carried out on three transects at nine altitude positions for 24 hours of measurement time, measuring positions ranging from the ground level to 0cm, 10cm, 30cm, 60cm, 100cm, 150cm, 220cm, 300cm, to 400cm. Data processing carried out in this study is by entering data on air temperature, the measured ground surface into the Matlab application. It can be shown that temporal changes and vertical spatial variations in air temperature show different but relatively the same curve shapes in hot weather conditions during the day, expressed by using a mathematical model of the Fourier function and daily dynamics of air temperature gradients on various land surfaces is influenced by the process of heat absorption and thermal emission processes from the soil in various lands.
