Publisher: American Meteorological Society
Abstract: AbstractThe variability of Indo-Pacific SST on seasonal to multidecadal time scales is investigated using a recently introduced technique called nonlinear Laplacian spectral analysis (NLSA). Through this technique, drawbacks ...
Impact of Volcanic Eruptions on Decadal to Centennial Fluctuations of Arctic Sea Ice Extent during the Last Millennium and on Initiation of the Little Ice Age
Publisher: American Meteorological Society
Abstract: AbstractThis study evaluates different hypotheses of the origin of the Little Ice Age, focusing on the long-term response of Arctic sea ice and oceanic circulation to solar and volcanic perturbations. The authors analyze ...
Indo-Pacific Variability on Seasonal to Multidecadal Time Scales. Part II: Multiscale Atmosphere–Ocean Linkages
Publisher: American Meteorological Society
Abstract: AbstractThe coupled atmosphere?ocean variability of the Indo-Pacific domain on seasonal to multidecadal time scales is investigated in CCSM4 and in observations through nonlinear Laplacian spectral analysis (NLSA). It is ...
Multiscale Interactions in an Idealized Walker Circulation: Mean Circulation and Intraseasonal Variability
Publisher: American Meteorological Society
Abstract: high-resolution cloud-resolving model (CRM) simulation is developed here for a two-dimensional Walker circulation over a planetary-scale domain of 40 000 km for an extended period of several hundred days. The Walker cell ...
Droplet Activation and Mixing in Large-Eddy Simulation of a Shallow Cumulus Field
Publisher: American Meteorological Society
Abstract: his paper presents the application of a double-moment bulk warm-rain microphysics scheme to the simulation of a field of shallow convective clouds based on Barbados Oceanographic and Meteorological Experiment (BOMEX) ...
Multiscale Interactions in an Idealized Walker Cell: Analysis with Isentropic Streamfunctions
Publisher: American Meteorological Society
Abstract: new approach for analyzing multiscale properties of the atmospheric flow is proposed in this study. For that, the recently introduced isentropic streamfunctions are employed here for scale decomposition with Haar wavelets. ...
Optical Properties of Shallow Convective Clouds Diagnosed from a Bulk-Microphysics Large-Eddy Simulation
Publisher: American Meteorological Society
Multiscale Interactions in an Idealized Walker Cell: Simulations with Sparse Space–Time Superparameterization
Publisher: American Meteorological Society
Abstract: his paper discusses the sparse space?time superparameterization (SSTSP) algorithm and evaluates its ability to represent interactions between moist convection and the large-scale circulation in the context of a Walker cell ...
