Research brief: Tropical rainfall modelling errors decrease slowly, but storm resolving models may be the future

An international team including CLEX researchers examined models used by the Intergovernmental Panel for Climate Change (IPCC) over three model phases linked to IPCC reports – CMIP3, CMIP5, and the most recent, CMIP6, to see if they improved representation of tropical rainfall.

Research brief: SSTs create biases in how ENSO appears in CMIP5 models

A new study by CLEX researchers and colleagues shows that CMIP5 models as a group, when forced by observed sea surface temperatures underestimate, these atmospheric feedbacks on average by 23%. This underestimate can be linked to the wrong location at which climate models simulate the most important tropical circulation, called the Walker circulation.

Research brief: Experiments on the Monash Simple Climate Model

This study introduces the Monash Simple Climate Model (MSCM) experiment database. The MSCM is based on a simple climate model and provides a wide range of model simulations to illustrate how the climate system works.

Understanding the origin of ENSO diversity for improved forecasts

Forecasting El Niño Southern Oscillation (ENSO) events, and anticipating how they may change with global warming remains a significant challenge for climate researchers. An ENSO complexity workshop held in November 2017 produced a follow-up paper summarising what we know about ENSO and its predictability.

It is hoped this proposed synthesis of two ENSO structures, their interaction with each other and how they respond to external forcing, will be the catalyst for future research and practical applications for forecasting and determining the impacts of present and future ENSO events.
