Extreme precipitation may alter the mean diurnal cycle of precipitation for a specific region. How it can be handled while computing diurnal cycle? Any suggestion would be highly appreciated.
I would first think about your purpose in computing the cycle. You might also think about the period of record of the data you're analyzing and consider likelihood of extremes occurring in that period. Of course the likelihood will decrease with a decrease in annual excellence probability of any threshold you choose for defining "extreme", but will increase with increasing period of record.
Thanks Dr. Geoffrey M. Bonnin for your kind suggestion and I agree with you at this point. However, I am looking for a quantitative answer rather than qualitative. Right now, I am working at this problem and is in search of any related published document. Any further suggestion would be highly appreciated.
