Large sensitivity to freshwater forcing location in 8.2 ka simulations
The 8.2 ka event is a key test case for simulating the coupled climate response to changes in the Atlantic Meridional Overturning Circulation (AMOC). Recent advances in...- publication PDF

Investigation of the viscous potential using an MHD simulation
The viscous interaction between the solar wind and Earth's magnetosphere is extremely difficult to study through direct observations. The viscous contribution to the polar cap...- publication PDF

Poleward excursions by the Himalayan subtropical jet over the past four centuries
Since the 1980s, the subtropical jet stream has generally moved poleward, but its behavior varies by region and season. Here we examine the interannual variability and trends in...- publication PDF

Prominence mass supply and the cavity
A prevalent but untested paradigm is often used to describe the prominence-cavity system: the cavity is under-dense because it is evacuated by supplying mass to the condensed...- publication PDF
