Empirical Formulas Between Outdoor Temperature And Humidity

Outdoor temperature and humidity are vital variables for many aspects of life, such as determining the electrical and electronic component lifetime. However, an existing relationship between outdoor temperature and humidity in our ordinary mind is in exponential form. Hence, it isn't easy to imagine their correlation straightly. This study was devoted to obtaining a more straightforward format to connect outdoor temperature and humidity. More than fifty thousand latest data were collected using automatic measurements to both variables for 12 months at our Hydrometeorological Monitoring Station. This station location is on Research Center for Physics - BRIN (Badan Riset Dan Inovasi Nasional, National Research and Innovation Agency Republic of Indonesia). Data analysis used the piecewise linear regression method, a method that is usually used for diode analysis. This method was also suitable with the collected data, and the purpose of this research was to make a simple relation between temperature and humidity. The result shows that there were 12 linear equations where their constants were a little bit different as a function of the month. Applying one of these equations to the suitable case, we can predict humidity data lost if we know the temperature and vice versa. This study should be expanded in the future for data from four-season countries due to contrasting climates between tropical countries and subtropical countries.
