Study of Synoptic and Bioclimatology conditions of heat index at stations of coastal and see of south and its effects on human health

Since the reported temperature by weather station only reading of temperature inside Box Screen Regardless of other atmospheric parameters and including it is humidity so it cannot be represented our real feeling from the weather temperature because hot weather whereas the humidity is high it will be hotter in a way that when the temperature is 35°C with presence of relative humidity 55%the temperature will be about 43°C. In this paper, using of the heat index the actual temperature feeling the in warm months, July, June and August for a period of 10 years at 40 synoptic stations in the southern half of the country are calculated and Zoning Isotherm maps real sense in ArcGIS and Were compared with Typical isotherms Maps. The results showed that although the warm southern coastal areas at lower temperature show But actual temperatures have a higher sense of emotional distance from the beach and the actual temperature less humidity is low. Thresholds at each frequency due to real emotional problems were classified in four classes; each class creates a special situation. Synoptic conditions that result in high-temperature heat wave and get a real feel extremely dangerous in terms of coastal stations were investigated. Timely forecasts and warnings for the organization of heat waves on a hot, humid weather in the areas one of these organizations is to reduce the losses due to these ills.
