Abstract
The natural disasters caused by extreme precipitations significantly have increased around the world. In the US, wild fires and flooding appear to increase year-by-year. The extreme precipitations are attributed to the climate change. Over recent years we have successfully used the random walk to simulate the global warming in many places around the world. This encourages us to use the random walk model to simulate the precipitations. In this investigation, we used the random walk model to simulate the precipitations in 50 US state capitals for the 20th century. The results show that the random walk can approximately simulate the precipitation in these cities in both 1/–1 and decimal forms. Thus the results suggest the random mechanism is one of causes for unusual precipitations over recent years.
