A NERSC INCITE projectBridging the Gap between Climate and Weather
The distinction between climate and weather was expressed most succinctly by science fiction writer Robert A. Heinlein: “Climate is what you expect; weather is what you get.” But as global warming produces more noticeable changes on a planetary scale, how do we even know what to expect in a particular region?

Understanding Magnetic Explosions
Magnetic reconnection has broad importance for almost all areas of plasma physics
Solar flares can eject a billion tons of charged particles into space at a speed of 1 million km per hour, disrupting navigation and communications satellites, and sometimes even electrical grids on Earth, while producing bright auroras in the polar regions. How so much energy can be released so quickly has perplexed scientists for decades.
"Magnetic reconnection differs from a conventional explosion in that the energy is not released equally in all directions," explained James F. Drake, Professor of Physics at the University of Maryland, whose recent research has focused on this subject. "Instead, the plasma flows in from one direction and flows out in another."
