RISSpectral Transformation Using a Cubed-Sphere Grid for a Three-Dimensional Variational Data Assimilation System
Publisher: American Meteorological Society
Abstract: tmospheric numerical models using the spectral element method with cubed-sphere grids (CSGs) are highly scalable in terms of parallelization. However, there are no data assimilation systems for spectral element numerical ...
Characteristics of a Spectral Inverse of the Laplacian Using Spherical Harmonic Functions on a Cubed-Sphere Grid for Background Error Covariance Modeling
Publisher: American Meteorological Society
Abstract: n this study, a spectral inverse method using spherical harmonic functions (SHFs) represented on a cubed-sphere grid (SHF inverse) is proposed. The purpose of the spectral inverse method studied is to help with data ...
Land–Atmosphere Coupling at the Southern Great Plains Atmospheric Radiation Measurement (ARM) Field Site and Its Role in Anomalous Afternoon Peak Precipitation
Publisher: American Meteorological Society
Abstract: he multimodel Global Land?Atmosphere Coupling Experiment (GLACE) identified the semiarid Southern Great Plains (SGP) as a hotspot for land?atmosphere (LA) coupling and, consequently, land-derived temperature and precipitation ...
