Impacts of Initial Estimate and Observation Availability on Convective-Scale Data Assimilation with an Ensemble Kalman Filter
Publisher: American Meteorological Society
Abstract: The ensemble Kalman filter (EnKF) uses an ensemble of short-range forecasts to estimate the flow-dependent background error covariances required in data assimilation. The feasibility of the EnKF for convective-scale data ...
Mesoscale Predictability of the “Surprise” Snowstorm of 24–25 January 2000
Publisher: American Meteorological Society
Abstract: A mesoscale model is used here to investigate the possible sources of forecast error for the 24?25 January 2000 snowstorm along the east coast of the United States. The primary focus is the quantitative precipitation ...
Effects of Moist Convection on Mesoscale Predictability
Publisher: American Meteorological Society
Abstract: In a previous study by the authors, it was shown that the problematic numerical prediction of the 24?25 January 2000 snowstorm along the east coast of the United States was in some measure due to rapid error growth at ...
Overlap of Solar and Infrared Spectra and the Shortwave Radiative Effect of Methane
Publisher: American Meteorological Society
Abstract: This paper focuses on two shortcomings of radiative transfer codes commonly used in climate models. The first aspect concerns the partitioning of solar versus infrared spectral energy. In most climate models, the solar ...
Nonlinear Wear Response of WC Ni Cemented Carbides Irradiated by High Intensity Pulsed Ion Beam
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Surface hardening on WCNi cemented carbides was achieved by highintensity pulsed ion beam (HIPIB) irradiation, with formation of a binderless, densified, and “hilly†remelted top layer of a few خ¼m in depth and a shock ...
The Atmospheric Boundary Layer during Swell: A Field Study and Interpretation of the Turbulent Kinetic Energy Budget for High Wave Ages
Publisher: American Meteorological Society
Abstract: Analysis of the turbulent kinetic energy (TKE) budget for five slightly unstable cases with swell has been performed based on measurements of mechanical production, buoyancy production, turbulent transport, and dissipation ...
Observational Study of Marine Atmospheric Boundary Layer Characteristics during Swell
Publisher: American Meteorological Society
Abstract: By combining simultaneous data from an instrumented Air?Sea Interaction Spar (ASIS) buoy and a 30-m tower, profiles of wind and turbulence characteristics have been obtained at several heights from about 1 to 30 m above ...
Tourists’ Perceptions of Climate: Application of Machine Learning to Climate and Weather Data from Chinese Social Media
Publisher: American Meteorological Society
Effect of Hydrophilic Nanostructured Cupric Oxide Surfaces on the Heat Transport Capability of a Flat Plate Oscillating Heat Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With a surface treatment of hydrophilic cupric oxide (CuO) nanostructures on the channels inside a flatplate oscillating heat pipe (FPOHP), the wetting effect on the thermal performance of an FPOHP was experimentally ...
