0. 3   Thermohygrometric data

Thermohygrometric data have finally been plotted on a psychrometric chart, that allowed us to have a better understanding of how the dry bulb temperature is related to the humidity of our climates; the cooling needs, much higher in Colombo than in Semipalatinsk, are necessary not only due to the higher temperatures in this climate but also to the high humidity levels during the whole year. Statistical distributions of the temperatures also allow us to have a better understanding of the data in the chart.
