RISEnsemble Data Assimilation to Characterize Surface-Layer Errors in Numerical Weather Prediction Models
Publisher: American Meteorological Society
Abstract: xperiments with the single-column implementation of the Weather Research and Forecasting Model provide a basis for deducing land?atmosphere coupling errors in the model. Coupling occurs both through heat and moisture fluxes ...
Transport Processes in the Tropical Warm Pool Boundary Layer. Part I: Spectral Composition of Fluxes
Publisher: American Meteorological Society
Abstract: Spectral analysis of high-resolution turbulence data from the South Australian Cessna research aircraft is performed in an investigation of the multiscale nature of vertical transport processes in the atmospheric boundary ...
Transport Processes in the Tropical Warm Pool Boundary Layer. Part II: Vertical Structure and Variability
Publisher: American Meteorological Society
Abstract: The structure of the intertropical convergence zone ITCZ cloud-topped marine atmospheric boundary layer away from the most intense mesoscale convective systems during the Tropical Ocean Global Atmosphere Coupled Ocean?Atmosphere ...
Estimation of Surface Energy Balance from Radiant Surface Temperature and NOAA AVHRR Sensor Reflectances over Agricultural and Native Vegetation
Publisher: American Meteorological Society
Abstract: A model is developed to evaluate surface heat flux densities using the radiant surface temperature and red and near-infrared reflectances from the NOAA Advanced Very High Resolution Radiometer sensor. Net radiation is ...
Increasing the Skill of Probabilistic Forecasts: Understanding Performance Improvements from Model-Error Representations
Publisher: American Meteorological Society
Abstract: our model-error schemes for probabilistic forecasts over the contiguous United States with the WRF-ARW mesoscale ensemble system are evaluated in regard to performance. Including a model-error representation leads to ...
Model Uncertainty in a Mesoscale Ensemble Prediction System: Stochastic versus Multiphysics Representations
Publisher: American Meteorological Society
Abstract: multiphysics and a stochastic kinetic-energy backscatter scheme are employed to represent model uncertainty in a mesoscale ensemble prediction system using the Weather Research and Forecasting model. Both model-error schemes ...
Tropical Island Convection in the Absence of Significant Topography. Part I: Life Cycle of Diurnally Forced Convection
Publisher: American Meteorological Society
Abstract: Diurnally forced convection was observed over the Tiwi Islands, north of the Australian continent, as part of the Maritime Continent Thunderstorm Experiment. Immature peninsula-scale (5?15 km) sea breezes were observed to ...
Land–Atmosphere Interaction in a Semiarid Region: The Bunny Fence Experiment
Publisher: American Meteorological Society
Abstract: Southwestern Australia, with a semiarid Mediterranean climate, has been extensively cleared of native vegetation for winter-growing agricultural species The resultant reduction in evapotranspiration has increased land ...
The Maritime Continent Thunderstorm Experiment (MCTEX): Overview and Some Results
Publisher: American Meteorological Society
Abstract: A description is given of the Maritime Continent Thunderstorm Experiment held over the Tiwi Islands (12°S, 130°E) during the period November?December 1995. The unique nature of regularly occurring storms over these islands ...
The Tropical Air–Sea Propagation Study (TAPS)
Publisher: American Meteorological Society
Abstract: he purpose of the Tropical Air?Sea Propagation Study (TAPS), which was conducted during November?December 2013, was to gather coordinated atmospheric and radio frequency (RF) data, offshore of northeastern Australia, in ...
