بررسی روند تغییرات دما و بارندگی متاثر از تغییر اقلیم در ایستگاه سینوپتیک بابلسر

Abstract
Industrialization of Community and increase of greenhouse gas in past decades induced global warming and changing of climate parameters that known as Climate Change. These climate changes make variations of temporal and local precipitation patterns change all around the world. Temperature and precipitation are two important parameters for determination of climate class of a region and variations of these two parameters effects on various systems. Thus the study on climate change commonly focus on these parameters. In this research, the annual rainfall and temperature trend of Babolsar synoptic station during 52 years was studied. Study time duration was divided into two 26 years period (1968-1993 period and 1994-2019 period). T peer test was carried out by SPSS software on temperature parameters showed that second period had warmer temperature comparing to first period. Mann-Kendal test carried out on 52 years temperature data by use of MAKESENs in EXCELL. The result showed that the trend is ascending. T peer test down on annual rainfall data of two periods by SPSS software showed that there is no significant difference between two time series data however the second period average annual rainfall (890) was smaller than first one(911 mm).The mean temperature, mean maximum temperature, mean minimum temperature, minimum absolute temperature trends in 1% significant level are ascending and maximum absolute temperature has no trend but has leap change but annual rainfall during 52 years had no trend.
