In this research study the daily and annually trends of precipitation in the central Kavir basin of Iran during 1951- 2007. The pixel data of daily precipitation from APHRODITE’s data base with a spatial resolution of 0.25˚ have been used. The Mann-Kendall (MK) nonparametric test has been used for determining the precipitation trend in this area. The trends have been tested in 3 levels 90%, 95% and 99%. This study illustrated that in confidence level of 99%, some area such as Loot Kavir had decreasing trend and some other area such as western and north heights of basin had rising trend of precipitation. But more than 80% of
area doesn’t indicate any significant trend for annually precipitation in this 58 years period.
