DE SOUZA, Amaury et al. Modelo de Thom para o zoneamento bioclimático de Mato Grosso do Sul. Rev. geogr. Norte Gd. [online]. 2010, n.46, pp.137-147. ISSN 0718-3402.

The objective of this study was to evaluate the climate conditions of Mato Grosso do Sul, using the index of temperature and humidity (ITU), and present the bioclimatic mapping relating to thermal comfort. The ITU values were estimated from data of temperature and relative humidity for the period 1979 to 2008. Four intervals of ITU were used to classify human performance (ITU<74: comfort; 74<ITU<79: hot: 79<ITU<84: very hot, and ITU>84: extremely hot), and two intervals to classify the Livestock (79< ITU<84: dangerous and ITU>84: emergency). We conclude that the prevailing mood is one of two alternating seasons throughout the year: hot and humid summer and dry winter with warmer temperatures, the results showed a higher risk of thermal discomfort during the period from October to April, compared to the period between May and September. The most critical period occurred between December and March. Although it was observed that with ITU values between 77.9 and 83.9, humans and animals can suffer some degree of heat stress during the hottest hours of the day, negatively affecting both.
