A General Description of Entrainment in Buoyant Cloudy Plumes Including the Effects of Mixing-Induced Evaporation
Publisher: American Meteorological Society
Abstract: In this work, the steady-state one-dimensional axisymmetric plume theory is revisited and generalized to include the effects of nonhomogeneous updraft velocity and buoyancy profiles across the plume, environmental shear, ...
Different El Niño Types and Tropical Cyclone Landfall in East Asia
Publisher: American Meteorological Society
Abstract: his study examines whether there exist significant differences in tropical cyclone (TC) landfall between central Pacific (CP) El Niño, eastern Pacific (EP) El Niño, and La Niña during the peak TC season (June?October) and ...
Two-Dimensional Evaluation of ATHAM-Fluidity, a Nonhydrostatic Atmospheric Model Using Mixed Continuous/Discontinuous Finite Elements and Anisotropic Grid Optimization
Publisher: American Meteorological Society
Abstract: his paper presents the first attempt to apply the compressible nonhydrostatic Active Tracer High-Resolution Atmospheric Model?Fluidity (ATHAM-Fluidity) solver to a series of idealized atmospheric test cases. ATHAM-Fluidity ...
A Prognostic Turbulence Scheme for the Nonhydrostatic Plume Model ATHAM
Publisher: American Meteorological Society
Abstract: The presented turbulence scheme was developed for the Active Tracer High-Resolution Atmospheric Model (ATHAM) to parameterize the effect of subgrid-scale turbulence. In contrast to the commonly used assumption of local ...

ENSO Forecasts near the Spring Predictability Barrier and Possible Reasons for the Recently Reduced Predictability
Publisher: American Meteorological Society
Abstract: AbstractA cross-validated statistical model has been developed to produce hindcasts for the 1980?2016 November?December?January (NDJ; assumed El Niño peak) mean Niño-3.4 sea surface temperature anomalies (SSTA). A linear ...
An Assessment of Recent and Future Temperature Change over the Sichuan Basin, China, Using CMIP5 Climate Models
Publisher: American Meteorological Society
Abstract: AbstractThe Sichuan basin is one of the most densely populated regions of China, making the area particularly vulnerable to the adverse impacts associated with future climate change. As such, climate models are important ...
Block-Structured Adaptive Grids on the Sphere: Advection Experiments
Publisher: American Meteorological Society
Abstract: A spherical 2D adaptive mesh refinement (AMR) technique is applied to the so-called Lin?Rood advection algorithm, which is built upon a conservative and oscillation-free finite-volume discretization in flux form. The AMR ...
A Comparison of Model- and Satellite-Derived Aerosol Optical Depth and Reflectivity
Publisher: American Meteorological Society
Abstract: The determination of an accurate quantitative understanding of the role of tropospheric aerosols in the earth's radiation budget is extremely important because forcing by anthropogenic aerosols presently represents one of ...
