Abstract El Niño–Southern Oscillation (ENSO) has significant variations and nonlinearities in its pattern strength. ENSO events vary their position along the equator, with some located central Pacific (CP) others east (EP). To study how these are reflected global teleconnections, both observations idealized atmospheric general circulation model (AGCM) simulations analyzed. Clear exist observed teleconnections of sea level pressure (SLP) precipitation. However, it is difficult to distinguish...
Abstract The meteorological conditions are investigated over the state of Victoria, Australia on 7 February 2009, day ‘Black Saturday’ fires. Daytime temperatures exceeding 45°C, strong surface winds and extremely dry combined to produce worst fire weather record. A high‐resolution nested simulation with UK Met Office Unified Model available observations used identify important mesoscale features day. highest resolution domain has horizontal grid spacing 444 m reproduces most aspects...
Abstract. Weather and climate models are complex pieces of software which include many individual components, each is evolving under pressure to exploit advances in computing enhance some combination a range possible improvements (higher spatio-temporal resolution, increased fidelity terms resolved processes, more quantification uncertainty, etc.). However, after years relatively stable environment with little choice processing architecture or programming paradigm (basically X86 processors...
Abstract State‐of‐the‐art coupled general circulation models (CGCMs) have substantial errors in their simulations of climate. In particular, these can lead to large uncertainties the simulated climate response (both globally and regionally) a doubling CO 2 . Currently, tuning parameterization schemes CGCMs is significant part developed. It not clear whether such actually improves models. The process (in general) neither documented, nor reproducible. Alternative methods as flux correcting are...
Abstract. This study introduces the Monash Simple Climate Model (MSCM) experiment database. The simulations are based on Globally Resolved Energy Balance (GREB) model to three different aspects of climate simulations: (1) understanding processes that control mean climate, (2) response a doubling CO2 concentration, and (3) scenarios external forcing (CO2 concentration solar radiation). A series sensitivity experiments in which elements system turned off various combinations used address (2)....

Abstract. This study introduces the Monash Simple Climate Model (MSCM) experiment database. The model simulations are based on Globally Resolved Energy Balance (GREB) model. They provide a basis to three different aspects of climate simulations: (1) understanding processes that control mean climate, (2) response doubling CO2 concentration, and (3) scenarios external concentration solar radiation forcings.
