Frost refers to conditions in which the air temperature reaches zero or zero degrees Celsius at an altitude of about one to two meters from the ground. Almost every part of the economy may be affected by unexpected frostbite And in most cases, freezing occurs negatively. Freezing temperatures are zero or less than zero. The term "frost" means that the temperature is zero or less than that in a given region. Because of the importance and application of forecast freezing and regional economic development planning Attempts were made to investigate the changes and the beginning and end of the ice in the western regions of Iran during a twenty-year period, using the general data of the atmospheric circulation data and its changes.
