This report responds to a request by the National Climate Science Advisory Committee (NCSAC) for input to its strategic discussions in the area of climate processes research. Specifically, it summarises the current state of climate processes research in Australia, identifies gaps, and provides options for moving the area forward into the next decade.

In this paper, CLEX researchers considered the steady-state response of the atmosphere to an imposed large-scale flow. They found that under these steady-state conditions, humidity increases with the precipitation rate, while the lapse rate (rate of decrease of temperature with height) increases.

This paper investigates the annual cycle in cloud and rainfall measurements over the western equatorial Indian Ocean. While there is a single period of strong rainfall over the region during December-January each year, there are two periods of increased high-top clouds associated with convection.

This observational study of radiative convective equilibrium finds that this equilibrium breaks down in areas of a few thousands kilometres on a side. This has implications cloud model simulations in climate models.

Prof Christian Jakob (Monash University). Climate models have significant errors in precipitation globally, but in particular in the tropics. Most models overestimate annual mean tropical precipitation, with the largest errors occurring over the warm tropical oceans of the Western Pacific, Indian Ocean and Atlantic. In addition to the mean errors, there are significant shortcomings in the rainfall variability in space and time. Given its immediate impact on tropical rainfall, most of the errors are usually attributed to shortcomings in the... View Article

Weather time scales will be needed for models to accurately simulate the dynamic contribution to future precipitation changes with global warming. This will better reproduce spatial patterns and reduce regional uncertainties, especially in the tropics.
