I am expecting that precipitation data, just like rainfall data, should show some seasonality in which case seasonal autoregressive integrated moving average (SARIMA) methods might be helpful in modelling them. Find out if my expectation of seasonality is supported empirically. SARIMA methods capture seasonal tendencies as well as are applications of ARIMA modelling.
Amol ji @ thanks for your help. I already mention that ARMA is not helping in my case. Could you please suggest me any literature or codes on machine learning methods.
