(American Meteorological Society, 2010)The authors combine urban and soil?vegetation surface parameterization schemes with one-dimensional (1D) boundary layer mixing and radiation parameterizations to estimate the maximum impact of increased surface albedo on ... -
Sensitivity of Atmospheric Motion Vectors Height Assignment Methods to Semitransparent Cloud Properties Using Simulated Meteosat-8 Radiances
(American Meteorological Society, 2010)This paper presents the sensitivity to various atmospheric parameters of two height assignment methods that aim to retrieve the cloud-top height of semitransparent clouds. The use of simulated Meteosat-8 radiances has the ... -
Topographic Effects on the Surface Radiation Balance in and around Arizona’s Meteor Crater
(American Meteorological Society, 2010)The individual components of the slope-parallel surface radiation balance were measured in and around Arizona?s Meteor Crater to investigate the effects of topography on the radiation balance. The crater basin has a diameter ... -
A Case Study on the Impact of Moisture Variability on Convection Initiation Using Radar Refractivity Retrievals
(American Meteorological Society, 2010)A case study illustrating the impact of moisture variability on convection initiation in a synoptically active environment without strong moisture gradients is presented. The preconvective environment on 30 April 2007 ... -
Daytime Mixed Layer over the Santiago Basin: Description of Two Years of Observations with a Lidar Ceilometer
(American Meteorological Society, 2010)Two years of high-resolution backscatter profiles obtained with a commercial lidar ceilometer in Santiago Basin (33.5°S, 70.6°W) are analyzed. The generally large aerosol load in the Santiago atmospheric boundary layer ... -
Variability and Trends of High Temperature, High Humidity, and Sultry Weather in the Warm Season in China during the Period 1961–2004
(American Meteorological Society, 2010)Using the daily maximum air temperature and mean humidity observations at 394 surface weather stations across China, the changes in the annual number of days of high temperature weather (HTW), high humidity weather (HHW), ... -
A Method to Infer the Three Cartesian Wavelengths of a Mountain Wave from Three Soundings
(American Meteorological Society, 2010)The number of atmospheric sounding techniques and the amount of missions within each of them continue to grow at the present time. The probability of having two or more profiles in a given region and time interval therefore ... -
Estimates of Cn2 from Numerical Weather Prediction Model Output and Comparison with Thermosonde Data
(American Meteorological Society, 2010)Area-averaged estimates of Cn2 from high-resolution numerical weather prediction (NWP) model output are produced from local estimates of the spatial structure functions of refractive index with corrections for the inherent ... -
Evaluation of HOAPS-3 Ocean Surface Freshwater Flux Components
(American Meteorological Society, 2010)Today, latent heat flux and precipitation over the global ocean surface can be determined from microwave satellite data as a basis for estimating the related fields of the ocean surface freshwater flux. The Hamburg Ocean ... -
Subtropical Cloud-Regime Transitions: Boundary Layer Depth and Cloud-Top Height Evolution in Models and Observations
(American Meteorological Society, 2010)In this study, the mean and variability of boundary layer height (BLH) are analyzed along a transect in the eastern Pacific Ocean for the summer of 2003 using BLH estimates based on the height of the main relative humidity ... -
A Simple Model to Predict Scalar Dispersion within a Successively Thinned Loblolly Pine Canopy
(American Meteorological Society, 2010)Bark beetles kill millions of acres of trees in the United States annually by using chemical signaling to attack host trees en masse. As an attempt to control infestations, forest managers use synthetic semiochemical sources ... -
Green Roof Mitigation Potential for a Proxy Future Climate Scenario in Chicago, Illinois
(American Meteorological Society, 2011)The Advanced Research version of the Weather Research and Forecasting Model (ARW) coupled with an urban canopy model is used to investigate the potential of vegetative (green) roof technology to mitigate against ongoing ... -
