Mechanisms governing the persistence and diurnal cycle of a heavy rainfall corridor
Observations and convection-permitting simulations are used to study a 12-day warm-season heavy precipitation corridor over the central U.S. plains and Mississippi River valley...- publication PDF

Moisture and dynamical interactions maintaining decoupled Arctic mixed-phase...
Observations suggest that processes maintaining subtropical and Arctic stratocumulus differ, due to the different environments in which they occur. For example, specific...- publication PDF

The substorm cycle as reproduced by global MHD models
Recently, Gordeev et al. (2015) suggested a method to test global MHD models against statistical empirical data. They showed that four community-available global MHD models...- publication PDF

Relating magnetic reconnection to coronal heating
It is clear that the solar corona is being heated and that coronal magnetic fields undergo reconnection all the time. Here we attempt to show that these two facts are...- publication PDF
