Ensemble Variance Calibration for Representing Meteorological Uncertainty for Atmospheric Transport and Dispersion Modeling
(American Meteorological Society, 2009)In the event of the release of a dangerous atmospheric contaminant, an atmospheric transport and dispersion (ATD) model is often used to provide forecasts of the resulting contaminant dispersion affecting the population. ... -
Resolving Nonstationary Spectral Information in Wind Speed Time Series Using the Hilbert–Huang Transform
(American Meteorological Society, 2010)This work is motivated by the observation that large-amplitude wind fluctuations on temporal scales of 1?10 h present challenges for the power management of large offshore wind farms. Wind fluctuations on these scales are ... -
Basic Diagnosis and Prediction of Persistent Contrail Occurrence Using High-Resolution Numerical Weather Analyses/Forecasts and Logistic Regression. Part II: Evaluation of Sample Models
(American Meteorological Society, 2009)A probabilistic forecast to accurately predict contrail formation over the conterminous United States (CONUS) is created by using meteorological data based on hourly meteorological analyses from the Advanced Regional ... -
Observational Study of Wind Channeling within the St. Lawrence River Valley
(American Meteorological Society, 2009)The presence of orography can lead to thermally and dynamically induced mesoscale wind fields. The phenomenon of channeling refers to the tendency for the winds within a valley to blow more or less parallel to the valley ... -
An Indirect Data Assimilation Scheme for Deep Soil Temperature in the Pleim–Xiu Land Surface Model
(American Meteorological Society, 2009)The Pleim?Xiu land surface model (PX LSM) has been improved by the addition of a second indirect data assimilation scheme. The first, which was described previously, is a technique in which soil moisture is nudged according ... -
On the Algorithms Used to Compute the Standard Deviation of Wind Direction
(American Meteorological Society, 2009)The standard deviation of wind direction is a very important quantity in meteorology because in addition to being used to determine the dry deposition rate and the atmospheric stability class, it is also employed in the ... -
Unusually High Differential Attenuation at C Band: Results from a Two-Year Analysis of the French Trappes Polarimetric Radar Data
(American Meteorological Society, 2009)The differential phase (ΦDP) measured by polarimetric radars is recognized to be a very good indicator of the path integrated by rain. Moreover, if a linear relationship is assumed between the specific differential phase ... -
Sensitivity of Typhoon Track Predictions in a Regional Prediction System to Initial and Lateral Boundary Conditions
(American Meteorological Society, 2009)Tropical cyclone (TC) track predictions from the operational regional nonhydrostatic TC forecast system of the Taiwanese Central Weather Bureau (CWB) are examined for their sensitivities to initial and lateral boundary ... -
Space and Time Variations in Turbulence during the Manhattan Midtown 2005 Field Experiment
(American Meteorological Society, 2009)The Manhattan Midtown-2005 field experiment (MID05) collected turbulence observations at 12 street-level sites (at 3-m height) and at 5 rooftop sites (at 220-m average height). The MID05 observations of 30-min averaged ... -
Why a Large Amount of Rain Falls over the Sea in the Vicinity of Western Sumatra Island during Nighttime
(American Meteorological Society, 2009)Precipitation measurements from the Tropical Rainfall Measuring Mission satellite indicate that annual rainfall over the sea in the vicinity of western Sumatra Island is among the highest on the earth, and most of this ... -
Precipitation and Water Vapor Transport in the Southern Hemisphere with Emphasis on the South American Region
(American Meteorological Society, 2009)December?March climatologies of precipitation and vertically integrated water vapor transport were analyzed and compared to find the main paths by which moisture is fed to high-rainfall regions in the Southern Hemisphere ... -
Measurements and Simulations of Nadir-Viewing Radar Returns from the Melting Layer at X and W Bands
(American Meteorological Society, 2009)Simulated radar signatures within the melting layer in stratiform rain?namely, the radar bright band?are checked by means of comparisons with simultaneous measurements of the bright band made by the ER-2 Doppler radar ... -
Observations of Atmospheric Structure and Dynamics in the Owens Valley of California with a Ground-Based, Eye-Safe, Scanning Aerosol Lidar
(American Meteorological Society, 2009)First results are presented from the deployment of the NCAR Raman-Shifted Eye-Safe Aerosol Lidar (REAL) in the Owens Valley of California during the Terrain-Induced Rotor Experiment (T-REX) in March and April 2006. REAL ... -
Theoretical Assessment of Uncertainty in Regional Averages due to Network Density and Design
(American Meteorological Society, 2009)Weather Research and Forecasting (WRF) model simulations are performed over Russia for July and December 2005, 2006, and 2007 to create a ?dataset? to assess the impact of network density and design on regional averages. ... -
The Value of ENSO Forecast Information to Dual-Purpose Winter Wheat Production in the U.S. Southern High Plains
(American Meteorological Society, 2009)The value of El Niño?Southern Oscillation (ENSO) forecast information to southern high plains winter wheat and cattle-grazing production systems was estimated here by simulation. Although previous work has calculated average ... -
Cloud Variability over the Indian Monsoon Region as Observed from Satellites
(American Meteorological Society, 2009)This study focuses on documenting the seasonal progression of the Asian monsoon by analyzing clouds and convection in the pre-, peak-, and postmonsoon seasons. This effort was possible as a result of the movement of ... -
A Climatology of Nocturnal Low-Level Jets at Cabauw
(American Meteorological Society, 2009)A climatology of nocturnal low-level jets (LLJs) is presented for the topographically flat measurement site at Cabauw, the Netherlands. LLJ characteristics are derived from a 7-yr half-hourly database of wind speed profiles, ... -
Influence of Anomalous Warmer Winter on Statistics of Measured Winter Precipitation Data
(American Meteorological Society, 2009)The winter of 2006/07 in Japan was the warmest in more than 100 years. To evaluate the effects of such an anomalous warmer winter on measured winter precipitation data, gauge-measured precipitation amounts from an area ... -
