Two diagrams display summary precipitation in desert cimate grasslands. There are data about every month in two years: in 1980 year and in 2000 year.
The main trend that we can see: the number of fallout have reached less numbers in 2000 year. Also, there are less precipitation in some months (for example, march and april). In this time – fallout distributed smoothly in 1980 year.
The most precipitation months are march and april (about 300 mm per month) in 1980 year. There are some month when the number of fallout achieved 250 mm per month (january, november and december). In general, all of months have precipitation about 200 mm per month.
