The relationship between average monthly temperature and monthly rainfall in each watershed of the country andsome watersheds of neighboring countries based on the information of the World Bank database

The increase in the average temperature on Earth in recent years is the result of the increasingproduction and accumulation of greenhouse gasses in the atmosphere. An increase in the Earth'stemperature can lead to a decrease in precipitation in some areas. The watersheds in whichprecipitation changes due to temperature increase are of great importance for water resources planningand management. In this study, we investigated the relationship between the average monthlyprecipitation and the average monthly temperature in the watersheds of our country and someneighboring countries.
