Abstract: Climate has always been changing during the lifetime of the earth, and has appeared in the form of the ice age, hurricanes, severe and sudden temperature changes, precipitation and other climatic elements, and has dramatically influenced the environment, and in some cases, has caused severe changes and even destructions. Some of the most important aspects of climate changes can be found in precipitation types of different regions in the world and especially Guilan, which is under the influence of strong ground change and greenhouse gas emissions. Also, agriculture division, industrial activities and unnecessary land conversions have a huge influence on climate change. Climate change is a result of abnormalities of meteorology parameters. Generally, the element of precipitation is somehow included in most theories about climate change. The present study aims to show precipitation abnormalities in Guilan which lead to climate change, and possible deviations of precipitation measurement based on annual, seasonal and monthly series check. The Mann-Kendal test is used to show likely deviations leading to climate change. The trend of precipitation changes in a long-term study using this method. Also, the beginning and end of these changes are studied in five stations as representatives of all the thirteen weather stations. Then, the areas which have experienced climate change identified using the GIS software along with the severity of the changes with an emphasis on drought. These results can be used in planning and identifying the effects of these changes on the environment
