Statistical analysis of the temperature-humidity complex and time of wetness of a tropical climate in the Yucatán Peninsula in Mexico

We show that the atmospheric temperature-humidity complex (T-HC) of sites located in a tropical humid climate cannot be well characterized by annual average values. Better information is given by the systematic study of daily changes of temperature (T) and relative humidity (RH), which can be modeled with linear and parabolic functions. According to ISO 9223, we determine the time of wetness (TOW) for metallic surfaces in these environments using the T-HC. We recommend the analysis of the different T ranges in which TOW occurs in order to better explain material degradation processes and rates.
