Abstract
Variability and trends of sultry in Hormozgan province in Iran
Highlights
Hormozgan province in southern Iran was selected for this study
The long-term (1985 to 2013) data on temperature, relative humidity and vapor pressure of six stations (Table 1) of Hormozgan province were collected from the Meteorology Organization
The highest (170 days) being at Jask followed by 161 days at Abu Musa, 152 days at Kish, 135-136 days at Bandar Abbas and Bandar Lengeh and the lowest (67 days) at Minab
Summary
Sultry weather is always a problem in tropical and sub tropical counties that adversely affect the human efficiency and its health (Blazejczyk and Matzarakis 2007; Hass 2016) during summer months. Tabatabaei et al (2014) has prepared the maps of southern province of Iran showing various zones based on intensity of sultriness. The long-term (1985 to 2013) data on temperature, relative humidity and vapor pressure of six stations (Table 1) of Hormozgan province were collected from the Meteorology Organization. The index of sultriness was calculated for each day by the following equation Tabatabaei et al (2014); Where, D is the index of sultriness intesity, RH is the relative humidity(per cent) and T is the average temperature (0C). The mean monthly frequency of sultry days (Fig.1) shows that during cold months (December to February) the sultry weather condition is not felt at any of the stations.
