Short-Period Modulations in Aerosol Optical Depths over the Central Himalayas: Role of Mesoscale Processes
(American Meteorological Society, 2008)Multiyear measurements of spectral aerosol optical depths (AODs) were made at Manora Peak in the central Himalaya Range (29°22?N, 79°27?E, ?1950 m above mean sea level), using a 10-channel multiwavelength solar radiometer ... -
Volcanic Ash Transport from Mount Asama to the Tokyo Metropolitan Area Influenced by Large-Scale Local Wind Circulation
(American Meteorological Society, 2008)The eruption of the Mount Asama volcano on 16 September 2004 produced an ash cloud and led to ashfall in the Tokyo metropolitan area that lies on the Kanto Plain. Satellite images showed the ash cloud drifting toward the ... -
Microphysics of Raindrop Size Spectra: Tropical Continental and Maritime Storms
(American Meteorological Society, 2007)This work uses raindrop size spectra measured at the surface in tropical continental storms to determine the associated parameters of the best-fit gamma distributions. The physical processes responsible for those parameters ... -
Automatic Designation of the Melting Layer with a Polarimetric Prototype of the WSR-88D Radar
(American Meteorological Society, 2008)A new polarimetric melting layer detection algorithm (MLDA) is utilized to estimate the top (melting level) and bottom boundaries of the melting layer and is tailored for operational deployment. Melting layer designations ... -
Analysis of Near-Surface Atmospheric Variables: Validation of the SAFRAN Analysis over France
(American Meteorological Society, 2008)Système d?analyse fournissant des renseignements atmosphériques à la neige (SAFRAN) is a mesoscale atmospheric analysis system for surface variables. It produces an analysis at the hourly time step using ground data ... -
Climatic Controls and Hydrologic Impacts of a Recent Extreme Seasonal Precipitation Reversal in Arizona
(American Meteorological Society, 2008)The winter (December?February) of 2005/06 ranked as the driest in the instrumental record (since 1895) for nearly all regions of Arizona. The city of Phoenix, Arizona, recorded no precipitation during this time period, ... -
A Simple Empirical Model for Estimating the Intensity Change of Tropical Cyclones after Landfall along the South China Coast
(American Meteorological Society, 2008)The intensity change of past (1976?2005) tropical cyclones that made landfall along the south China coast (110.5°?117.5°E) is examined in this study using the best-track data from the Hong Kong Observatory. The change in ... -
Radar Observations of Rainfall Variability Using Non-Rayleigh Signal Fluctuations
(American Meteorological Society, 2008)The spatial variability and temporal variability of precipitation are widely recognized. In particular, rainfall rates can fluctuate widely in regions where the raindrops are clustered and where mean conditions are changing ... -
Intercalibrated Passive Microwave Rain Products from the Unified Microwave Ocean Retrieval Algorithm (UMORA)
(American Meteorological Society, 2008)The Unified Microwave Ocean Retrieval Algorithm (UMORA) simultaneously retrieves sea surface temperature, surface wind speed, columnar water vapor, columnar cloud water, and surface rain rate from a variety of passive ... -
