Though it was discovered over 40 years ago, we still do not understand the MJO, in the sense of being able to state a simple mathematical model that explains its basic features. I will present evidence that the MJO is what some of us now call a "moisture mode", best analyzed by examining the budget of moist static energy or moist entropy. I will argue that cloud-radiative feedbacks are important to the maintenance of the MJO, while horizontal advection of moisture is important to its eastward propagation. I will present evidence from observations, theory, general circulation models, and cloud-resolving models to this effect. -------------- next part -------------- An HTML attachment was scrubbed...

The Status of Planetary Life Support Systems: Climate and the Earth System The Bolin Centre for Climate Research, Stockholm University, invites you to attend a public science forum involving presentations by three climate and atmospheric science Professors recently honoured by Stockholm University and a subsequent moderated discussion. Taking climate in its broadest context, the focus is on the ?planetary life-support systems? that were identified by an international expert group meeting in Stockholm in 2009. These include climate, aerosols, stratospheric ozone, air quality, nitrogen and phosphorus cycles, fresh water, land use, ocean acidification and biodiversity.

CO2 degassing linked to late Quaternary seismicity and climate change Speaker: Dr. Tonguc Uysal Research Fellow Queensland Geothermal Energy Centre of Excellence, The University of Queensland, Australia School of Earth Sciences, The University of Queensland, Australia Time: 11 September 2013, 15:00 ? 16:00 Venue: Room U26, Geoscience Building, Stockholm University Abstract: Fluid overpressures in excess of the hydrostatic are known to reduce shear stress causing fault failure. In regions of continental extension, deeply derived CO2 and meteoric water circulating to depths of 10?15 km below the earth surface are the major fluid sources; however, the cause and timing of CO2 and meteoric water accumulations has remained unexplored. We obtained high-precision U-series ages of carbonate veins that filled spaces created by overpressurised CO2 ?rich meteoric fluids during active normal faulting in southwest Turkey (Aegean region). Trace element, Sr, and O-C isotope data in combination of U-series dating reflect cyclic changes in fluid chemistry in relation to CO2 accumulation and CO2 exsolution following seismically triggered depressurisation. Timing of carbonate veining corresponds well to periods of low to transitional insolation in the Northern Hemisphere but is notably absent during periods of high insolation. Although glacial episodes are generally associated with dry climatic conditions, there is substantial evidence suggesting that the eastern Mediterranean climate was wetter during the Last Glacial Maximum, which may also be the case for earlier periods of lower insolation. Whereas ?background? tectonics is the ultimate driver of faulting, we argue climate-driven hydrological changes may have played an important role in modulating CO2-rich fluid circulation and reducing fault strength, triggering earthquakes.

Aerosol alteration of Atlantic storms Introduction: Leonard Barrie Director for Research, Bolin Centre for Climate Research Professor for Climate and Atmospheric Science, Stockholm University Rodrigo Caballero Professor at the Department of Meteorology, Stockholm University Time: 3 September 2013, 15:00 ? 17:00 Venue: De Geersalen, Geoscience Building, Stockholm University Abstract: Atmospheric aerosols affect climate by scattering and absorbing sunlight and by modifying clouds. Model simulations published in a fresh paper in Nature Geoscience suggest that anthropogenic aerosols suppressed tropical storm activity over the Atlantic throughout much of the twentieth century. This link between Atlantic tropical cyclones and anthropogenic aerosols in the north atlantic is an important cross-over between the science of aerosol, clouds and dynamics and will benefit greatly from a good two hour discussion with many experts from these disciplines.
