Development of Verification Methodology for Extreme Weather Forecasts
Publisher: American Meteorological Society
Abstract: n 2006, the statistical postprocessing of the National Centers for Environmental Prediction (NCEP) Global Ensemble Forecast System (GEFS) and North American Ensemble Forecast System (NAEFS) was implemented to enhance ...
The Effects of Longwave Radiation in a Small Cumulus Cloud
Publisher: American Meteorological Society
Abstract: The effects of longwave radiation in a small cumulus cloud are investigated by a combination of a three-dimensional radiative transfer model as well as a slab-symmetric cloud dynamics model. The calculations indicate that ...
Improvement of Statistical Postprocessing Using GEFS Reforecast Information
Publisher: American Meteorological Society
Abstract: he National Oceanic and Atmospheric Administration/Earth System Research Laboratory (NOAA/ESRL) generated a multidecadal (from 1985 to present) ensemble reforecast database for the 2012 version of the Global Ensemble ...
Verification of Supercooled Cloud Water Forecasts with In Situ Aircraft Measurements
Publisher: American Meteorological Society
Abstract: In situ measurements of temperature (Ta), horizontal wind speed (V), dewpoint (Td), total water content (TWC), and cloud and supercooled cloud water (SCW) events, made during 50 flights from three research field programs, ...
Numerical Simulations of Stratus Clouds and Their Sensitivity to Radiation—A RACE Case Study
Publisher: American Meteorological Society
Abstract: The three-dimensional Canadian Mesoscale Compressible Community model has been run at high resolution (?x = 2 km, ?z = 50 m) to simulate stratus clouds observed on 1 September 1995 during the Radiation, Aerosol and Cloud ...
Measurement and Analysis of Moisture Migration Characteristics in Subgrade of Excavation Section
Publisher: American Society of Civil Engineers
Abstract: To cope with the phenomenon of moisture imbalances in subgrades due to excavation, the resistivity of different excavation subgrades (deep excavation section, shallow excavation section, and cut-and-fill transition section) ...
Comparison of Three Cloud Forecast Schemes with In Situ Aircraft Measurements
Publisher: American Meteorological Society
Abstract: In situ aircraft measurements, collected during three research projects, are used to compare forecasts from three explicit cloud schemes. These schemes include the Canadian operational Sundqvist (SUND) scheme, the Tremblay ...
Systematic Error Analysis and Calibration of 2-m Temperature for the NCEP GEFS Reforecast of the Subseasonal Experiment (SubX) Project
Publisher: American Meteorological Society
Abstract: AbstractThe National Centers for Environmental Prediction have generated an 18-yr (1999?2016) subseasonal (weeks 3 and 4) reforecast to support the Climate Prediction Center?s operational mission. To create this reforecast, ...
Load Transfer and Collapse Resistance of RC Flat Plates under Interior Column Removal Scenario
Publisher: American Society of Civil Engineers
Abstract: Reinforced concrete (RC) flat-plate structures are vulnerable to punching shear failure at their slab-column connections, potentially leading to a catastrophic progressive collapse. In practice, the slab-column connection ...
Study on Prelithiation Technology of Hard Carbon Electrode Using Stable Metal Lithium Powder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The prelithiation of hard carbon electrode using stable metal lithium powder to compensate the lithium loss during the first lithium insertion is studied in this work. The results show that when the pressure on lithium ...
