RISA Three-Dimensional Wave-Activity Relation for Pseudomomentum
Publisher: American Meteorological Society
Abstract: A three-dimensional, nonhydrostatic local wave-activity relation for pseudomomentum is derived from the nonhydrostatic primitive equations in Cartesian coordinates by using an extension of the momentum?Casimir method. The ...
Impacts of Ice Microphysics on Rainfall and Thermodynamic Processes in the Tropical Deep Convective Regime: A 2D Cloud-Resolving Modeling Study
Publisher: American Meteorological Society
Abstract: The effects of ice microphysics on rainfall and thermodynamic processes in the tropical deep convective regime are examined based on hourly zonal-mean data from a pair of two-dimensional cloud-resolving simulations: one ...
An Application of the Helmholtz Theorem in Extracting the Externally Induced Deformation Field from the Total Wind Field in a Limited Domain
Publisher: American Meteorological Society
Abstract: new application of the Helmholtz theorem that divides the horizontal wind into purely rotational, purely divergent, and harmonic deformational flow is put forward in this study. The formulas and methods, with consideration ...
High-Resolution Modeling of Typhoon Morakot (2009): Vortex Rossby Waves and Their Role in Extreme Precipitation over Taiwan
Publisher: American Meteorological Society
Abstract: high-resolution nonhydrostatic numerical model, the Advanced Regional Prediction System (ARPS), was used to simulate Typhoon Morakot (2009) as it made landfall over Taiwan, producing record rainfall totals. In particular, ...
Bayesian Model Averaging with Stratified Sampling for Probabilistic Quantitative Precipitation Forecasting in Northern China during Summer 2010
Publisher: American Meteorological Society
Abstract: o study the impact of training sample heterogeneity on the performance of Bayesian model averaging (BMA), two BMA experiments were performed on probabilistic quantitative precipitation forecasts (PQPFs) in the northern ...
