IntroductionOne of the most interesting research areas of the scientific community in recent
years is the study of the behavior and regimes of rainfall at the local, regional and global …

In this research we used multivariable statistical methods (cluster and discriminative
analysis) with the purpose of the recognition of spatiotemporal differences of …

In order to detect different PRECIPITATION REGIME s of Iran monthly precipitation
observations from Jan 1951 through Dec 1999 have been analyzed. Using this data set 588 …

Introduction Changes in rainfall regime can represent the effects of climate change.
Reduction and increase in rainfall affect many environmental phenomena such as runoff, air …

In this study to segregate Iran's climate precipitation, 130 climate variables were used from
81 synoptic meteorological stations and then 98 combined variables were calculated …

Today, studying climatic variations with respect to different climate variables such as
precipitation, evaporation, temperature, and air pressure in various parts of the world is …

IntroductionOne of the main goals in climate studies is to do climate classification. Climatic
divisions and the identification of the most important factors affecting each area is one way of …

Introduction: Planning and management of water resources in Iran are affected by tempo-
spatial distribution of rainfall. Therefore, study of PRECIPITATION can be a vital variable for …

In the present study, the information of 31 synoptic weather stations in the period of 1987-
2010 were used to delineate Iran's Precipitation regions. For this purpose, each month's …

Because the type and number of variables used in determining regional precipitation
climates can lead to the production of different climate boundaries, an attempt was made to …
