Assessments of the Process and Mutation of Limit indices of Temperature and Precipitation in Hormozgan Province

Coastal province of Hormozgan with continuing periods of severe heat and humid summers, low precipitation and variety of regions with different topographic features has a special climatic condition. This province like the other regions of our country is affected by the climatic changes resulting from global warming, and in addition to temperature increase and high oscillation of precipitation, we can see the rising of sea level, erosion of coastal edges and salinity of the regions water. So that, review the climatic parameters and change of its limit values can be used in the future planning for its adaptation and cope with it. In this study, by using the data of synoptic stations of the area, the mean of seasonal and annual temperature and precipitation together with their limit values have been discussed. In order to study the homogeneity of data, multi phases regression method was implemented and different statistical methods, percentage indices and determining the critical points of the basic period have been used for specifying limit values. The overall result obtained from this study has been the increase of heat and decrease of precipitation in this province together with increasing high oscillation of precipitation and limit indices of temperature which necessitates the programmers of the province to consider this important issue.
