Modelling and simulation of seasonal rainfall

چکیده
Abstract: We propose and justify a model for seasonal rainfall using a copula of maximum entropy to model the joint distribution and using gamma distributions to model the marginal monthly rainfalls. The model allows correlation between individual months and thereby enables a much improved model for seasonal variation. A central theme is the principle of maximum entropy which we use to find the most parsimonious representation for the underlying distributions—using the minimum possible number of parameters to model the relevant physical characteristics. A particular emphasis is the use of the gamma distribution to model the marginal monthly rainfalls.

Modelling and Simulation of Seasonal Rainfall Using the Principle of Maximum Entropy
We use the principle of maximum entropy to propose a parsimonious model for generation of simulated rainfall during the wettest three-month season at a typical location on the east coast of Australia. The model uses a checkerboard copula of maximum entropy to model the joint probability distribution for total seasonal rainfall and a set of two-parameter gamma distributions to model each of the ...
متن کاملa Comparison Study Between the Joint Probability Approach and Time Series Rainfall Modelling in Coastal Detention Pond Analysis (RESEARCH NOTE)
In tidally affected coastal catchments detention pond should be provided to store flood surface water. A comparison between the full simulation approach based on the joint probability method and time series rainfall modeling via the annual maximum of pond level was undertaken to investigate the assumptions of independence between variables that are necessary in the joint probability method. The...

Multi site modeling of rainfall is one of the most important issues in environmental sciences especially in watershed management. For this purpose, different statistical models have been developed which involve spatial approaches in simulation and modeling of daily rainfall values. The hidden Markov is one of the multi-site daily rainfall models which in addition to simulation of daily rainfall...

r a 200 .061 : +64 4 3 iwa.co.n Summary This study is devoted to simulation of the interannual variability of daily rainfall, such as the mean and variance of seasonal rainfall totals and the correlation between seasonal rainfall totals and a seasonal climate variable (e.g., an index of atmospheric or oceanic circulation). Prior work established that a mixture of chain-dependent processes, invo...
متن کاملModelling extreme rainfalls using a modi®ed random pulse Bartlett±Lewis stochastic rainfall model (with uncertainty)
A modi®ed random pulse Bartlett±Lewis stochastic rainfall model is used for extreme rainfall simulation. The model features the use of a generalised pareto distribution (GPD) to represent the depths of high intensity raincells. A point rainfall record, obtained from a UK site is used to test the model. Parameter estimation is carried out using a two-stage approach based on the generalised likel...
