Aims & Backgrounds: One of the most important incidents of heavy precipitation is that each year there are many damages. Precipitation regimes help to identify the climate of each region. A heavy precipitation regime can help in identifying the climate of each region. Identification of these regimes is one of the most important prerequisites for environmental planning, especially water resources management and land management Programs.In this research, Iran's heavy precipitation regime is planned for the period of 20 years (1996-2016).
Methodology: In this study, for the implementation of the PCA model, a 153 ×12 matrix was created. Then, from the types of rotations in the factor analysis, the Equamax period had the most appropriate load factor on the study stations. Therefore, the analysis showed that 6 factors explained about 89% of cumulative dispersion.
Conclusion: The 8 regions of the diagnosis include: Caspian Sea (Caspian coastline), North Azarbaijan (Iranian and Azerbaijani border stations), Azerbaijani regime (stations from central and southern Azerbaijan),
Southern Zagros regiment (Khuzestan plain and coastal strip and Persian
Gulf shelters)., Mountainous region (mountains of western Iran and
mountainous regions surrounding and dispersed in Khorasan), the Dry Central - East - South Coast regime (a large part of Iran), the Eastern Alborz regime (regions of northwest of Iran and stations of Golestan province), the middle Zagros regime The western part of Iran and dispersed in stations from northwest of Iran).
Keywords: Iran, main component analysis, multi-average clustering, heavy rainfall regime, Equamax rotation
