Moving Cellular Structure of Fog Echoes Obtained with a Millimeter-Wave Scanning Doppler Radar at Kushiro, Japan
(American Meteorological Society, 2005)Observations of fogs with a millimeter-wave scanning Doppler radar were conducted at Kushiro in Hokkaido, Japan, in the summer seasons of 1999 and 2000. Three typical types of plan position indicator (PPI) displays were ... -
Retrieval of Model Grid-Scale Heat Capacity Using Geostationary Satellite Products. Part I: First Case-Study Application
(American Meteorological Society, 2005)In weather forecast and general circulation models the behavior of the atmospheric boundary layer, especially the nocturnal boundary layer, can be critically dependent on the magnitude of the effective model grid-scale ... -
The Influence of Meteorological Conditions on the Wet Deposition of Mercury in Southern Florida
(American Meteorological Society, 2005)Source?receptor relationships for mercury (Hg) and other trace elements wet deposited in southeastern Florida were investigated using daily event precipitation samples collected over a 1-yr period in 1995?96. Data collected ... -
Validation of an Urban Surface Exchange Parameterization for Mesoscale Models—1D Case in a Street Canyon
(American Meteorological Society, 2005)A detailed urban parameterization scheme is used in and above a street canyon. To validate this new scheme, the model is run offline on a vertical column (one-dimensional simulations), using measurements from a 30-m-high ... -
A Comparison of GOES Sounder– and Cloud Lidar- and Radar-Retrieved Cloud-Top Heights
(American Meteorological Society, 2005)An assessment of the performance of the Geostationary Operational Environmental Satellite (GOES) sounder cloud-top pressure product is presented. GOES sounder cloud-top-height data were compared with values derived from a ... -
Fitting an Exponential Distribution
(American Meteorological Society, 2005)Exponential distributions of the type N = N0 exp(??t) occur with a high frequency in a wide range of scientific disciplines. This paper argues against a widely spread method for calculating the ? parameter in this distribution. ... -
Separation between Cloud-Seeding and Air-Pollution Effects
(American Meteorological Society, 2005)Enhancement of precipitation by cloud-seeding operations has been reported in many studies around the world in the last several decades. On the other hand, suppression of rain and snow by urban and industrial air pollution ... -

Optical Properties of Aerosol Particles over the Northeast Pacific
(American Meteorological Society, 2005)In July 2002, atmospheric aerosol measurements were conducted over the northeast Pacific Ocean as part of the Subarctic Ecosystem Response to Iron Enhancement Study (SERIES). The following aerosol quantities were measured: ... -
Rain/No-Rain Classification Methods for Microwave Radiometer Observations over Land Using Statistical Information for Brightness Temperatures under No-Rain Conditions
(American Meteorological Society, 2005)One of the goals of the Global Precipitation Measurement project, the successor to the Tropical Rainfall Measuring Mission (TRMM), is to produce a 3-hourly global rainfall map using several spaceborne microwave radiometers. ... -
Daytime Cycle of Low-Level Clouds and the Tropical Convective Boundary Layer in Southwestern Amazonia
(American Meteorological Society, 2005)During the wet season in the southwestern Amazon region, daytime water transport out of the atmospheric mixed layer into the deeper atmosphere is shown to depend upon cloud amounts and types and synoptic-scale velocity ... -
Application of Satellite-Derived Atmospheric Motion Vectors for Estimating Mesoscale Flows
(American Meteorological Society, 2005)This study demonstrates methods to obtain high-density, satellite-derived atmospheric motion vectors (AMV) that contain both synoptic-scale and mesoscale flow components associated with and induced by cumuliform clouds ... -
Application of a Multigrid Method to a Mass-Consistent Diagnostic Wind Model
(American Meteorological Society, 2005)A multigrid numerical method has been applied to a three-dimensional, high-resolution diagnostic model for flow over complex terrain using a mass-consistent approach. The theoretical background for the model is based on a ... -
Measuring Canopy Structure and the Kinematics of Subcanopy Flows in Two Forests
(American Meteorological Society, 2005)A better understanding of forest subcanopy flows is needed to evaluate their role in the horizontal movement of scalars, particularly in complex terrain. This paper describes detailed measurements of the canopy structure ... -
Impacts of an Extreme Early-Season Freeze Event in the Interior Pacific Northwest (30 October–3 November 2002) on Western Juniper Woodlands
(American Meteorological Society, 2005)In mid-autumn 2002, an exceptional 5-day cold spell affected much of the interior Pacific Northwest, with minimum temperatures averaging 13°C below long-term means (1953?2002). On 31 October, minimum temperature records ... -
Drag Force Solid State Anemometer and Vane
(American Meteorological Society, 1966)The design and performance of a two-component drag force anemometer is discussed. The device utilizes semiconductor strain gages to produce full scale voltage outputs as large as 2.5 V without amplification. A novel method ... -
The Bias in Moment Estimators for Parameters of Drop Size Distribution Functions: Sampling from Exponential Distributions
(American Meteorological Society, 2005)The moment estimators frequently used to estimate parameters for drop size distribution (DSD) functions being ?fitted? to observed raindrop size distributions are biased. Consequently, the fitted functions often do not ... -
