Abstract
In this study, the data of coincident temperature and relative humidity in Bushehr coastal station (1993-2017) were discussed to estimate the corresponding values with probabilities of 95% and 99%. This value in the design of large structures for determining the method of calculating air conditioning are used. For this job, graphical and numerical methods were used. The graphical method is based on the empirical cumulative function and the basis of the numerical or statistical methods is the fit of the best probability cumulative function. In numerical methods, data from the hot month, hot season and all months of the year were used. To determine the coincident relative humidity at the same time as the estimated dry temperature, the average relative humidity amongst the data was used. The results showed that the statistical method used to determine the dry temperature corresponding to different probabilities for all data of the year is more appropriate than the method that uses season and hot month data, but obtains higher values than the graphical method. This difference occurred due to the placement of maximum data at the top of the fitted curve in the statistical method and the use of observation data in the graphical method. In addition, at the Bushehr coastal station, the average annual dry temperature and the temperature corresponding to different probabilities, has a significant upward trend. Therefore, it is recommended that in the design of structures with a life span of 50 years on the coasts of Bushehr, the specified dry temperature corresponding to probabilities of 95 and 99 present is 1.7 and 1.8 degrees Celsius, respectively, should be considered higher than estimated values. Therefore, while recommending the use of the generalized graphic method of this paper, it is suggested that at Bushehr coastal station, the dry temperature corresponding to probabilities of 95% and 99% is estimated to be 37.1 and 39.2 degrees Celsius, respectively, and the relative humidity is 55% and 52% respectively.
