CAWCR technical report, 40. Comparison of techniques for the calibration of coupled model forecasts of Murray Darling Basin seasonal mean rainfall
Charles Andrew; Hendon Harry H.; Wang Q.J.; et al. - Centre for Australian Weather and Climate Research, 2011Ensemble forecasts of South Eastern Australian rainfall from POAMA 1.5, a coupled oceanatmosphere dynamical model based seasonal prediction system run experimentally at the Bureau of Meteorology, tend to be under dispersed leading to overconfident probability forecasts. The poor reliability of seasonal forecasts based on dynamical coupled models is a barrier to their adoption as official outlooks by the Bureau of Meteorology. One approach to correcting this problem is model calibration, in which the probability distribution produced by the model is adjusted in light of available information ab ...

Published by: Centre for Australian Weather and Climate Research ; 2011Ensemble forecasts of South Eastern Australian rainfall from POAMA 1.5, a coupled oceanatmosphere dynamical model based seasonal prediction system run experimentally at the Bureau of Meteorology, tend to be under dispersed leading to overconfident probability forecasts. The poor reliability of seasonal forecasts based on dynamical coupled models is a barrier to their adoption as official outlooks by the Bureau of Meteorology. One approach to correcting this problem is model calibration, in which the probability distribution produced by the model is adjusted in light of available information about its past performance. Several distinct methods for calibrating seasonal rainfall forecasts for South Eastern Australia derived from the POAMA 1.5 ensemble are compared for accuracy and reliability in order to assess their suitability for application to real-time seasonal forecasts. The calibration methods investigated were: a variance inflation method (IOV); a Bayesian joint probability (BJP) calibration technique; and a singular vector regression technique (SVD) based on co-varying patterns of model and observed rainfall. Calibration was carried out for model grid points in the Murray Darling region. Assessment was carried out using a mix of standard skill scores widely used in operational forecasting. It was found that the BJP method resulted in the best correction to forecast reliability while IOV improved reliability only modestly and the SVD scheme had a negative impact on reliability. Further study of the application of these methods to real-time forecasts is recommended.

CAWCR technical report, 39. Assessment of international seasonal rainfall forecasts for Australia and the benefit of multi-model ensembles for improving reliability
In this report we assess forecasts from Predictive Ocean Atmosphere Model for Australia (POAMA) in comparison to international dynamical coupled model forecast systems, which are archived as part of the ENSEMBLES project. We investigate how universal the lack of reliability is in dynamical forecasts of regional rainfall, in order to highlight any potential for improvement of the POAMA system. The systems assessed in this report show that overconfidence and lack of reliability for regional rainfall forecasts is a common problem. Due to the clear need for improved reliability and more accurate s ...

We investigate how universal the lack of reliability is in dynamical forecasts of regional rainfall, in order to highlight any potential for improvement of the POAMA system. The systems assessed in this report show that overconfidence and lack of reliability for regional rainfall forecasts is a common problem. Due to the clear need for improved reliability and more accurate seasonal rainfall forecasts for hydrological applications, we have explored the benefit of combining a range of operationally available models into a multi-model ensemble, which can cancel uncorrelated error, increase spread and reduce model error. Our results indicate that there is benefit in adding POAMA version P24 to the operational models from the European Centre for Medium-Range Weather Forecasts (ECMWF), the UK Meteorological Office (UKMO) and Météo France (MF), into an equally weighted multi-model ensemble, to increase the reliability and consistency of accurate regional rainfall forecasts.

Verification of the TIGGE and WRF Models in forecasting the precipitation event for 3rd February 2010 over Zambia
Nkonde Edson - NOAA, 2010In this case study, attempt was made to verify the performances of the TIGGE and WRF models in simulating rainfall over southern Africa for the period from 1st November 2009 to 10th February 2010, with 24 and 48 hrs lead time. We have tested the skills of the models in forecasting heavy rainfall event, in excess of 40mm per day. Special emphasis was given to rainfall event that occurred on the 3rd of February 2010 over Zambia. The associated atmospheric conditions prior and during the rainfall event were also analyzed, both in analysis and forecasted fields.
Over Southern Africa, all th ...
