Abstract: A series of 10-day forecast experiments has been carried out to investigate the sensitivity of a global semi-Lagrangian model to the value of the uncentering parameter ?, the magnitude of the time step for the dynamics, ...

Abstract: Two parallel 5-year climate simulations have been carried out to assess the effect of changing from an Eulerian to a semi-Lagrangian formulation of a general circulation model's dynamical core with the physical parameterizations ...

Abstract: The humidity data retrieved from the TIROS Operational Vertical Sounder (TOVS) measurements is assimilated into the Goddard Earth Observing System (GEOS) data assimilation system. The study focuses on the impact of the ...

Abstract: To assess the impact of dynamical formulation on climate simulations, a semi-Lagrangian and an Eulerian dynamical core have been used for 5-yr climate simulations with the same physical parameterizations. The comparison ...
