Evaluation of the Climatic Parameters Trend Changes in North of IRAN (Mazandaran Province) Using Synoptic Stations Data of the Region
Keywords:
Climate Change, Climatic Parameters, Synoptic Stations, Mazandaran provinceAbstract
In this study, in order to investigate the phenomenon of climate change in Mazandaran province, the statistics of 4 important synoptic stations of the region have been used. Considering the importance of meteorological parameters of temperature and rainfall in climate change studies, the most important characteristics affecting these factors include average daily sunshine hours, daily rainfall, average daily temperature, average maximum daily temperature and average minimum daily temperature in selected stations in terms of trends and their changes during the available statistical time periods of the stations were investigated and researched. According to the trend curve of sunshine hours, it is clear that there are large fluctuations in the average. On the other hand the results about all synoptic station have shown large fluctuations in the rainfall recorded at all station. So that as we get closer to the present time, these changes have witnessed more fluctuations. The temperature fluctuations of all stations, which have been examined daily , have shown large temperature changes in the area of all synoptic station. It is worth mentioning that the closer we get to the present time, the better we see temperature changes and temperature increases. The examination of the average maximum and minimum temperature also confirms the large changes of these two parameters in this area and confirms the impact of the climate change phenomenon in this area. Considering that this province is one of the poles of rice production in the country, and on the other hand, in terms of other agricultural products and various citrus fruits that are grown in this area, we will see many changes in these products in the future, so that if careful planning. If it is not done to deal with the harm effects of climate change in the study area and other areas, it can have destructive effects on the agriculture of the area.
