About me

I am a climate scientist and my research focus is on how the land and the atmosphere interact with each other. I use state of the art land surface models coupled to atmospheric models to answer various scientific questions on this topic.

Current projects

Regional climate modeling for the southwest of Western Australia

Global climate models typically have a horizontal resolution of approximately 100-200 km. This too coarse for informing decision-making at the farm scale, i.e., a resolution of 1-10 km. This project is making use of a state-of-the art regional climate model to dynamically downscale outputs from global climate models to provide usable current and future climate information for the southwest of Western Australia.

What are the impacts of land-cover change on weather and climate in the southwest of Western Australia?

The southwest of Western Australia is a region of extensive land-cover change with an estimated 13 million hectares of native vegetation cleared for Agricultural land-use since European settlement. The on-going project investigates the impacts of such an extensive change in land-use on the atmosphere using both models and observations.

How does vegetation respond to increasing levels of atmospheric CO2?

Vegetation uses CO2 from the atmosphere during photosynthesis and loose water-vapor to the atmosphere during this process. As the amount of CO2 in the atmosphere increases, plants act to reduce their stomatal opening to minimize the amount of water-vapor lost per unit of Carbon gained. This has a net warming effect and it is therefore critical that this “optimal” stomatal behavior is accurately represented within climate models. This project is making use of the best available data to develop and test a more accurate stomatal conductance model used within the climate model used within Australian for weather forecasting and climate predictions.
