Heating and Kinetic Energy Dissipation in the NCAR Community Atmosphere Model

Data Assimilation in the NCAR Community Atmosphere Model

The Community Atmosphere Model (CAM) has several well known biases that have important dynamical implications for research. Some examples of these biases include a cold temperature bias near the tropopause at high latitudes, systematic biases in the mean zonal wind, and transient momentum fluxes that are too strong. One method for investigating the impacts that these biases have is to use data ...

Climate Implications of the Messinian Salinity Crisis using the NCAR Community Atmosphere Model (CAM3.1)

The Messinian Salinity Crisis (MSC) occurred nearly 6 million years ago when the Mediterranean Sea (MS) was isolated from the Atlantic Ocean. High rates of evaporation and diminishing water input led to a 1500 -2500 m drop in MS level. In this study, four 20-year simulations are run using the NCAR CAM3 configured with the SOM. Two of the simulations are designed to represent specific events tha...

Intermittent Dissipation and Heating in 3D Kinetic Plasma Turbulence.

High resolution, fully kinetic, three dimensional (3D) simulation of collisionless plasma turbulence shows the development of turbulence characterized by sheetlike current density structures spanning a range of scales. The nonlinear evolution is initialized with a long wavelength isotropic spectrum of fluctuations having polarizations transverse to an imposed mean magnetic field. We present evi...
