UNSW5: Convective cloud top vertical velocity estimations over Northern Australia

August 14, 2018 5:06 pm Published by Comments Off on UNSW5: Convective cloud top vertical velocity estimations over Northern Australia

Convective vertical velocity is crucial for understanding cloud-precipitation systems, yet direct observations of convective vertical velocity are currently limited. In this project, you will estimate convective cloud top vertical velocity using Himawari-8/9 satellite data available at 2 km resolution every 10 minutes over Northern Australia since July 2015.

Research brief: Regional climate models capture changes to extreme storms

July 12, 2018 6:46 am Published by Comments Off on Research brief: Regional climate models capture changes to extreme storms

Short, extreme rainfall events will increase in a warming climate, according to observations and climate models. Australian observations suggest these storms become smaller in size, with increased rainfall concentrating even more around the centre of the storm cell. However, there has been recent contradictory climate model research that suggests storm areas may become larger. To understand this contradiction the researchers compared two different model types to real world observations of storm cell changes that occurred with rising temperatures. An area... View Article

Research brief: Here’s what happens when you turn off convective parameterisations

Convective parameterizations are widely believed to be essential for realistic simulations of the atmosphere, but are crude in today's weather and climate models. CLEX researchers, report on what happens when a number of these models are run with these schemes simply turned off.
