Observed and Modeled Growing-Season Diurnal Precipitable Water Vapor in South-Central Canada
(American Meteorological Society, 2010)High-temporal-resolution total-column precipitable water vapor (PWV) was measured using a Radiometrics Corporation WVR-1100 Atmospheric Microwave Radiometer (AMR). The AMR was deployed at the University of Manitoba in ... -
A Numerical Study of Clear-Air Turbulence (CAT) Encounters over South Korea on 2 April 2007
(American Meteorological Society, 2010)On 2 April 2007, nine cases of moderate-or-greater-level clear-air turbulence (CAT) were observed from pilot reports over South Korea during the 6.5 h from 0200 to 0830 UTC. Those CAT events occurred in three different ... -
An Innovative Calibration Method for the Inversion of Satellite Observations
(American Meteorological Society, 2010)Retrieval schemes often use two important components: 1) a radiative transfer model (RTM) inside the retrieval procedure or to construct the learning dataset for the training of the statistical retrieval algorithms and 2) ... -
Application of a Signal Technique to the Source–Receptor Relationship in Three-Dimensional Tracer Simulations
(American Meteorological Society, 2010)Identifying pollutant sources that contribute to downstream locations is important for policy making and air-quality control. In this study, a computationally economic signal technique was implemented into a three-dimensional ... -
A Simple Technique for Creating Regional Composites of Sea Surface Temperature from MODIS for Use in Operational Mesoscale NWP
(American Meteorological Society, 2010)This paper describes a simple technique for creating regional, high-resolution, daytime and nighttime composites of sea surface temperature (SST) for use in operational numerical weather prediction (NWP). The composites ... -
Advances in Extracting Cloud Composition Information from Spaceborne Infrared Radiances—A Robust Alternative to Brightness Temperatures. Part I: Theory
(American Meteorological Society, 2010)Infrared measurements can be used to obtain quantitative information on cloud microphysics, including cloud composition (ice, liquid water, ash, dust, etc.), with the advantage that the measurements are independent of solar ... -
Evaluation of Three Planetary Boundary Layer Schemes in the WRF Model
(American Meteorological Society, 2010)Accurate depiction of meteorological conditions, especially within the planetary boundary layer (PBL), is important for air pollution modeling, and PBL parameterization schemes play a critical role in simulating the boundary ... -
Exploration of the MODIS Cloud-Top Property Products for the Investigation of Equatorial Wave Systems
(American Meteorological Society, 2010)The Moderate Resolution Imaging Spectroradiometer (MODIS) observations provide an unprecedented opportunity for studying cloud macrophysical (cloud-top pressure, temperature, height, and phase), microphysical (effective ... -
Risk of Strong Hurricane Winds to Florida Cities
(American Meteorological Society, 2010)A statistical procedure for estimating the risk of strong winds from hurricanes is demonstrated and applied to several major cities in Florida. The procedure, called the hurricane risk calculator, provides an estimate of ... -
Application of Dual-Polarization Radar Melting-Layer Detection Algorithm
(American Meteorological Society, 2010)A polarimetric melting-layer detection algorithm developed for an S-band radar has been modified for use by the King City C-band radar in southern Ontario, Canada. The technique ingests radar scan volume data to determine ... -
Three Recent Flavors of Drought in the Pacific Northwest
(American Meteorological Society, 2010)In common with much of the western United States, the Pacific Northwest (defined in this paper as Washington and Oregon) has experienced an unusual number of droughts in the past decade. This paper describes three of these ... -
The Midsummer Dry Spell’s Impact on Vegetation in Jamaica
(American Meteorological Society, 2010)The annual rainfall pattern of the intra-Americas sea reveals a bimodal feature with a minimum during the midsummer known as the midsummer dry spell (MSD). A first attempt is made to examine the impact of the MSD on ... -
Local Structure Parameters of Temperature and Humidity in the Entrainment-Drying Convective Boundary Layer: A Large-Eddy Simulation Analysis
(American Meteorological Society, 2010)Many wave propagation applications depend on the local, instantaneous structure parameters of humidity and of potential temperature . This study uses a large-eddy simulation to explore and compare the variability of and ... -
Ground-to-Air Gas Emission Rate Inferred from Measured Concentration Rise within a Disturbed Atmospheric Surface Layer
(American Meteorological Society, 2010)In reference to previously observed concentrations of methane released from a source enclosed by a windbreak, this paper examines a refined ?inverse dispersion? approach for estimating the rate of emission Q from a small ... -
The Measurement Factors in Estimating Snowfall Derived from Snow Cover Surfaces Using Acoustic Snow Depth Sensors
(American Meteorological Society, 2010)At three Canadian test locations during the cold seasons of 2006 and 2007/08, snowfall measurements are derived from changes in the total depth of snow on the ground using multiple Campbell Scientific, Inc., SR50 ultrasonic ... -
An Analytical Model of Evaporation Efficiency for Unsaturated Soil Surfaces with an Arbitrary Thickness
(American Meteorological Society, 2010)Analytical expressions of evaporative efficiency over bare soil (defined as the ratio of actual to potential soil evaporation) have been limited to soil layers with a fixed depth and/or to specific atmospheric conditions. ... -
Influence of Indian Summer Monsoon on Aerosol Loading in East Asia
