Global-scale simulation of foreshock structures at the quasi-parallel bow shock
(2022-09-29)
A two-dimensional, global-scale hybrid simulation is carried out to study the kinetic structure of the quasi-parallel bow shock. In the simulation the bow shock forms by the interaction of the supersonic solar wind and the ...

A growing importance of large fires in conterminous United States during 1984-2012
(2022-12-01)
Fire frequency, extent, and size exhibit a strong linkage with climate conditions and play a vital role in the climate system. Previous studies have shown that the frequency of large fires in the western United States ...
Hall effect control of magnetotail dawn-dusk asymmetry: A three-dimensional global hybrid simulation
(2020-06-03)
Magnetotail reconnection and related phenomena (e.g., flux ropes, dipolarizing flux bundles, flow bursts, and particle injections) occur more frequently on the duskside than on the dawnside. Because this asymmetry can ...

Two-dimensional hybrid simulations are used to investigate how fast-mode compressional waves incident on a magnetopause current layer mode convert both linearly and nonlinearly to short wavelength (k(perpendicular to)rho(i) ...
Increased nitrogen export from eastern North America to the Atlantic Ocean due to climatic and anthropogenic changes during 1901-2008
(2023-01-25)
We used a process-based land model, Dynamic Land Ecosystem Model 2.0, to examine how climatic and anthropogenic changes affected riverine fluxes of ammonium (NH4+), nitrate (NO3-), dissolved organic nitrogen (DON), and ...
