Abstract
The intercomparisons of global 3-day forecast with the JMA model and the BMRC model are studied. Precise comparisons of verifications, diagnoses in the models and impact studies reveal that the main differences between the models are concerning with the strength of the diabatic heating and the Hadley circulation in the tropics. It is found in this study that the combination of the physical processes is important as well as each physical process to maintain the Hadley circulation and subtropical jets for the models.
