Low-Frequency Effects on Eddy Covariance Fluxes under the Influence of a Low-Level Jet
(American Meteorological Society, 2007)Turbulent bursts observed over a tall forest canopy during the initiation of a nocturnal low-level jet (LLJ) are studied with the help of wavelet analysis. The burst of turbulence is observed in response to a shear instability ... -
Atmospheric Circulation Effects on Wind Speed Variability at Turbine Height
(American Meteorological Society, 2007)Mean monthly wind speed at 70 m above ground level is investigated for 11 sites in Minnesota for the period 1995?2003. Wind speeds at these sites show significant spatial and temporal coherence, with prolonged periods of ... -
Empirical Estimation of Attenuation from Differential Propagation Phase Measurements at C Band
(American Meteorological Society, 2007)A polarimetric method is devised to correct for attenuation effects at C band on reflectivity ZH and differential reflectivity ZDR measurements. An operational cross-correlation analysis is used to derive advection vectors ... -
Impact of Increasing Urban Density on Local Climate: Spatial and Temporal Variations in the Surface Energy Balance in Melbourne, Australia
(American Meteorological Society, 2007)Variations in urban surface characteristics are known to alter the local climate through modification of land surface processes that influence the surface energy balance and boundary layer and lead to distinct urban climates. ... -
Description and Evaluation of the Characteristics of the NCAR High-Resolution Land Data Assimilation System
(American Meteorological Society, 2007)This paper describes important characteristics of an uncoupled high-resolution land data assimilation system (HRLDAS) and presents a systematic evaluation of 18-month-long HRLDAS numerical experiments, conducted in two ... -
Climate Variability and Corn Yields in Semiarid Ceará, Brazil
(American Meteorological Society, 2007)Understanding of climate influence on crop yields can help in the design of policies to reduce climate-related vulnerability in many parts of the world, including the target of this case study?the state of Ceará, Brazil. ... -
Depiction of the Variations of Great Plains Precipitation and Its Relationship with Tropical Central-Eastern Pacific SST
(American Meteorological Society, 2007)Several advanced analysis tools are applied to depict the time?frequency characteristics of the variations of Great Plains (GP) precipitation and its relationship with tropical central-eastern Pacific Ocean sea surface ... -
Estimation of Land Surface Heat Fluxes over the Tibetan Plateau Using GMS Data
(American Meteorological Society, 2007)A Surface Energy Balance System (SEBS) originally developed for the NOAA Advanced Very High Resolution Radiometer was applied to Geostationary Meteorological Satellite (GMS)-5 Visible/Infrared Spin-Scan Radiometer data ... -
Source Characterization with a Genetic Algorithm–Coupled Dispersion–Backward Model Incorporating SCIPUFF
(American Meteorological Society, 2007)This paper extends the approach of coupling a forward-looking dispersion model with a backward model using a genetic algorithm (GA) by incorporating a more sophisticated dispersion model [the Second-Order Closure Integrated ... -
An Automated Technique to Quality Control Radar Reflectivity Data
(American Meteorological Society, 2007)Echoes in radar reflectivity data do not always correspond to precipitating particles. Echoes on radar may result from biological targets such as insects, birds, or wind-borne particles; from anomalous propagation or ground ... -
Effect of Dewfall and Frostfall on Nighttime Cooling in a Small, Closed Basin
(American Meteorological Society, 2007)Series of tethered balloon soundings of temperature and humidity in Austria?s Gruenloch basin (floor elevation 1270 m MSL) on two June days showed that the water vapor mixing ratio fell by 2?3 g kg?1 overnight as dew or ... -
Diurnal Cycle of Water Vapor as Documented by a Dense GPS Network in a Coastal Area during ESCOMPTE IOP2
(American Meteorological Society, 2007)Global positioning system (GPS) data from a dense network have been used for the analysis of the diurnal cycle of water vapor over Marseille, France, during the second intensive observation period (IOP2; 21?26 June 2001) ... -
Optimization of an Instance-Based GOES Cloud Classification Algorithm
(American Meteorological Society, 2007)An instance-based nearest-neighbor algorithm was developed for a Geostationary Operational Environmental Satellite (GOES) cloud classifier. Expert-labeled samples serve as the training sets for the various GOES image ... -
