Cwa means that it has a hot moderate climate that is dry and arid, and it has a hot summer. The summer and winter seasons are easy to tell apart. The winter has a temperature of -3 degrees Celsius to 18 degrees. The summers are hotter than 22 degrees Celsius. Cwa will have an average precipitation of less than 250 mm.
The Cwa climate that I have selected is in western China. It is very hot and dry there, and it also has little rain. It is to far from the coast for the monsoons to reach it, so it only receives 5 inches on average.
