A Method to Estimate Vertically Integrated Amounts of Cloud Ice and Liquid and Mean Rain Rate in Stratiform Precipitation from Radar and Auxiliary Data
(American Meteorological Society, 2009)A method to retrieve total vertical amounts of cloud liquid and ice in stratiform precipitating systems is described. The retrievals use measurements from the vertically pointing Ka- and W-band cloud radars operated by the ... -
Rainfall Variability over Mountainous and Adjacent Lake Areas: The Case of Lake Tana Basin at the Source of the Blue Nile River
(American Meteorological Society, 2009)The water resource of the Blue Nile River is of key regional importance to the northeastern African countries. However, little is known about the characteristics of the rainfall in the basin. In this paper, the authors ... -
Five-Year Climatology of Midtroposphere Dry Air Layers in Warm Tropical Ocean Regions as Viewed by AIRS/Aqua
(American Meteorological Society, 2009)Many studies have commented on the presence of midtroposphere dry air layers in normally moist areas of the warm-pool region in the tropical western Pacific Ocean. In this study, 5 yr of relative humidity (RH) observations ... -
Short-Range Direct and Diffuse Irradiance Forecasts for Solar Energy Applications Based on Aerosol Chemical Transport and Numerical Weather Modeling
(American Meteorological Society, 2009)This study examines 2?3-day solar irradiance forecasts with respect to their application in solar energy industries, such as yield prediction for the integration of the strongly fluctuating solar energy into the electricity ... -
Enriched Analyses with Assimilation of SALLJEX Data
(American Meteorological Society, 2009)This paper aims at generating a set of enriched analyses by assimilating the data collected during the South American Low-Level Jet Experiment (SALLJEX) in southeastern South America during the summer season 2002/03. The ... -
On the Tropospheric Ozone Variations in a Coastal Area of Southwestern Europe under a Mesoscale Circulation
(American Meteorological Society, 2009)It is well established that surface ozone levels are greatly affected by orography, solar radiation intensity, meteorological conditions, and the levels of their precursors. In this work, the authors study the sea?land ... -
Remote Sensing of Cloud-Top Pressure Using Moderately Resolved Measurements within the Oxygen A Band—A Sensitivity Study
(American Meteorological Society, 2009)Reflected solar radiation measured by the Medium Resolution Imaging Spectrometer (MERIS) on the Environmental Satellite (Envisat) is currently used within the European Space Agency?s ground segment for the retrieval of ... -
A Combination of Cluster Analysis and Kappa Statistic for the Evaluation of Climate Model Results
(American Meteorological Society, 2009)The authors present a combination of different statistical methods for the validation of climate simulation data with respect to observational data of the same spatial and temporal coverage. It is assumed that simulated ... -
Formation of Convective Clouds at the Foothills of the Tropical Eastern Andes (South Ecuador)
(American Meteorological Society, 2009)This study examines the seasonal and diurnal dynamics of convective cloud entities?small cells and a mesoscale convective complex?like pattern?in the foothills of the tropical eastern Andes. The investigation is based on ... -
Estimating Urban Canopy Parameters Using Synthetic Aperture Radar Data
(American Meteorological Society, 2009)This paper introduces a remote sensing?based approach to rapidly derive urban morphological characteristics using radar satellite data. The approach is based on the expectation that the magnitude of the synthetic aperture ... -
Continuous Observations of Aerosol Profiles with a Two-Wavelength Mie-Scattering Lidar in Guangzhou in PRD2006
(American Meteorological Society, 2009)Continuous lidar observation was performed in Guangzhou, China, in the Pearl River Delta (PRD) observation campaign in July 2006 (PRD2006), using a two-wavelength Mie-scattering lidar (532 and 1064 nm) with a depolarization ... -
Developing Objective Operational Definitions for Monitoring Drought
(American Meteorological Society, 2009)Drought is a complex phenomenon that is difficult to accurately describe because its definition is both spatially variant and context dependent. Decision makers in local, state, and federal agencies commonly use operational ... -
Urban Flow and Dispersion Simulation Using a CFD Model Coupled to a Mesoscale Model
(American Meteorological Society, 2009)Flow and pollutant dispersion in a densely built-up area of Seoul, Korea, are numerically examined using a computational fluid dynamics (CFD) model coupled to a mesoscale model [fifth-generation Pennsylvania State ... -
The Influence of Air Temperature Inversions on Snowmelt and Glacier Mass Balance Simulations, Ammassalik Island, Southeast Greenland
(American Meteorological Society, 2010)In many applications, a realistic description of air temperature inversions is essential for accurate snow and glacier ice melt, and glacier mass-balance simulations. A physically based snow evolution modeling system ... -
Sudden Surface Warming–Drying Events Caused by Typhoon Passages across Taiwan
(American Meteorological Society, 2010)Typhoon passages across Taiwan can generate sudden surface warming in downslope regions. Special characteristics and mechanisms for 54 such warming events that were identified during the 1961?2007 period are examined. ... -
An Inferred Climatology of Icing Conditions Aloft, Including Supercooled Large Drops. Part II: Europe, Asia, and the Globe
(American Meteorological Society, 2009)Because of a lack of regular, direct measurements, limited information is available about the frequency and the spatial and temporal distribution of icing conditions aloft, including supercooled large drops (SLD). Research ... -
Ensemble Forecasts of Drought Indices Using a Conditional Residual Resampling Technique
(American Meteorological Society, 2009)The historical climate record and seasonal temperature and precipitation records provide useful datasets for making short-term drought predictions. A variety of methods have exploited these resources, but few have ... -
