| Cognition of the bioclimatic conditions of each location can be the first step in conducting many environmental studies. In fact, awareness of the capabilities and limitations of bioclimatic conditions provides planning and better management of human activities. This study was performed to determine the thermal comfort of Iran. For this purpose, the daily data of the climatic variables (air temperature, relative humidity, wind speed and cloudiness) in 193 synoptic stations was prepared from the Iran Meteorological Organization. First, based on the Physiological Equivalent Temperature index (PET), bioclimatic conditions, each of the stations studied. Then the long-term average bioclimatic conditions at each station were calculated for the whole year. Finally, database of the bioclimatic long-term conditions of all stations (with the dimensions of 193 * 366) had created. Using this database, bioclimatic daily conditions in Iran, interpolated to Kriging method. The following, monthly bioclimatic map of Iran was drawn. The results showed a high diversity of bioclimatic conditions on a scale of temporal or spatial. One place in Iran during the years also con has a very cold and hot condition. Likewise, in a specific time and in Iran, also the bioclimatic conditions indicate such a variety. In each month in Iran, can be seen special bioclimatic conditions. For example, in twelve months, respectively, a light warm (27.7 percent), warm (29.3 percent), very warm (30.8 percent), hot (5/45 percent), hot (2/42 percent), very warm (38 percent), g (31.3%) and climatic comfort (28.2 percent), cool (29.2 percent), cool (5/33 percent), cool (30.1 percent) and slightly cool (28.1%) in Iran Has been experienced. Based on this November is when the large part of the Iran (28.2 percent) has experienced climatic comfort. In the other months, extent of the climatic comfort conditions had been reduced. | ||
