Precipitation and Precipitation hardening are very important phenomena as they are equally useful in Chemistry (Solid State), Physical Metallurgy and Solid State Physics.
Since we are going to discuss solid solution strengthening (hardening) and precipitation strengthening, it is advisable to define the two terms.
In the studies conducted, it was indicated that greenhouse gasses accumulated in higher layers of the atmosphere have led to / will lead to higher temperatures on earth and changes in precipitation dynamics (Wentz et al.
It is expected that this terrestrial warming situation also affects atmospheric conditions and leads to changes in precipitation mechanisms.
The diurnal variability of precipitation is one of the pronounced climatic cycles.
and visual basic language for obtaining of maximum rainfall amount in other time bases from 24 hour to 8784 hour (one year), next output of these program that was 8 records for maximum rainfall in any time bases entered to excel software, then graph of these records drawn, as on this log-log graph X axis was time (hour) and Y axis was precipitation (mm), after that, a line that covered all of maximum precipitation drawn.
To highlight the differences between the periodic evolution of precipitation average values and the time evolution of the days with precipitation amounts of > 20 mm and 30 mm, data from the 1945-2010 period, being the most consistent, have been used, However, due consideration was given to the fact that meteorological stations are located in the most different geographical and physical conditions (Fig 1).
