| Summary: | In order to study the climate hazards, daily rainfall and temperature data
of 61 weather stations over the country were obtained from the
Meteorological Organization of Iran for the 1951–2007 period. The following
indices are defined as indications of climate hazards: sultriness of the air
or the heat index, cold days with minimum temperature below −5 °C, warm
days with maximum temperature above 32 °C, the share of extreme rain
days from the annual rainfall. The annual frequencies of these indices are
analyzed and the overall hazard index is computed using the Analytical
Hierarchical Process method.

The results show that the southern coastal areas and central deserts are the
most hazardous parts of the country, whereas, the northern Caspian coastal
lands and mountainous regions experience lower hazard alerts. The problem of
the northern parts is the cold days and that of the southern areas is the
hot and humid days. Despite the relatively equal occurrence of torrential
rains over the country, they are more harmful in the south than in the other
parts of the country. |
