The Behavior of Number Concentration Tendencies for the Continuous Collection Growth Equation Using One- and Two-Moment Bulk Parameterization Schemes
(American Meteorological Society, 2007)This paper presents a mathematical explanation for the nonconservation of total number concentration Nt of hydrometeors for the continuous collection growth process, for which Nt physically should be conserved for selected ... -
An Integrated Display and Analysis Methodology for Multivariable Radar Data
(American Meteorological Society, 2007)Polarimetric Doppler radars provide valuable information about the kinematic and microphysical structure of storms. However, in-depth analysis using radar products, such as Doppler-derived wind vectors and hydrometeor ... -
Formulation of an Index for Sea Breezes in Opposing Winds
(American Meteorological Society, 2007)A scaling analysis is conducted to explore the dependence of sea-breeze speed and inland occurrence in the presence of opposing winds on a set of dynamical parameters. The overall aim of the analysis is to develop an index ... -
Enhancement of Afternoon Thunderstorm Activity by Urbanization in a Valley: Taipei
(American Meteorological Society, 2007)Located in northern Taiwan, Taipei is a metropolis surrounded by hills and mountains that form a basin in which two river valleys funnel the surface airflow of this basin to the open sea. Because of the southwest monsoon, ... -
Vorticity-Based Detection of Tropical Cyclogenesis
(American Meteorological Society, 2007)Ocean wind vectors from the SeaWinds scatterometer aboard the Quick Scatterometer (QuikSCAT) satellite and Geostationary Operational Environmental Satellite (GOES) imagery are used to develop an objective technique that ... -
Climate Variability and Residential Water Use in the City of Phoenix, Arizona
(American Meteorological Society, 2007)In this investigation, how annual water use in the city of Phoenix, Arizona, was influenced by climatic variables between 1980 and 2004 is examined. Simple correlation coefficients between water use and annual mean ... -
Modeling the Effect of Chlorine Emissions on Ozone Levels over the Eastern United States
(American Meteorological Society, 2007)This paper presents model estimates of the effect of chlorine emissions on atmospheric ozone concentrations in the eastern United States. The model included anthropogenic molecular chlorine emissions, anthropogenic ... -
Daily Simulation of Ozone and Fine Particulates over New York State: Findings and Challenges
(American Meteorological Society, 2007)This study investigates the potential utility of the application of a photochemical modeling system in providing simultaneous forecasts of ozone (O3) and fine particulate matter (PM2.5) over New York State. To this end, ... -
Surface-to-Atmosphere Exchange in a River Valley Environment
(American Meteorological Society, 2007)Observations of the turbulent exchange between a river surface and the atmosphere in a mountainous area in southern Brazil are presented and discussed. A micrometeorological tower was installed directly above the surface ... -
Seasonal Simulation of Tropospheric Ozone over the Midwestern and Northeastern United States: An Application of a Coupled Regional Climate and Air Quality Modeling System
(American Meteorological Society, 2007)The impacts of air pollution on the environment and human health could increase as a result of potential climate change. To assess such possible changes, model simulations of pollutant concentrations need to be performed ... -
Consequences of Urban Stability Conditions for Computational Fluid Dynamics Simulations of Urban Dispersion
(American Meteorological Society, 2007)The validity of omitting stability considerations when simulating transport and dispersion in the urban environment is explored using observations from the Joint Urban 2003 field experiment and computational fluid dynamics ... -
Atmospheric Response to Local Upwelling in the Vicinity of New York–New Jersey Harbor
(American Meteorological Society, 2007)Multiply nested urbanized mesoscale model [Coupled Ocean?Atmosphere Mesoscale Prediction System (COAMPS)] simulations of the New York?New Jersey metropolitan region are conducted for 4?11 July 2004. The simulations differ ... -
Probabilistic Characterization of Atmospheric Transport and Diffusion
(American Meteorological Society, 2007)The observed scatter of observations about air quality model predictions stems from a combination of naturally occurring stochastic variations that are impossible for any model to simulate explicitly and variations arising ... -
On the Analysis of Atmospheric and Climatic Time Series
(American Meteorological Society, 2007)Linear parametric models are commonly assumed and used for unknown data-generating mechanisms. This study demonstrates the value of inferring statistics of meteorological and climatological time series by using a ... -
Statistical Model for Forecasting Monthly Large Wildfire Events in Western United States
(American Meteorological Society, 2007)The ability to forecast the number and location of large wildfire events (with specified confidence bounds) is important to fire managers attempting to allocate and distribute suppression efforts during severe fire seasons. ... -
Event-Based Climatology and Typology of Fog in the New York City Region
(American Meteorological Society, 2007)The character of fog in a region centered on New York City, New York, is investigated using 20 yr of historical data. Hourly surface observations are used to identify fog events at 17 locations under the influence of various ... -
Penalized Maximal t Test for Detecting Undocumented Mean Change in Climate Data Series
(American Meteorological Society, 2007)In this paper, a penalized maximal t test (PMT) is proposed for detecting undocumented mean shifts in climate data series. PMT takes the relative position of each candidate changepoint into account, to diminish the effect ... -
Modeling the Variability of Drop Size Distributions in Space and Time
(American Meteorological Society, 2007)The information on the time variability of drop size distributions (DSDs) as seen by a disdrometer is used to illustrate the structure of uncertainty in radar estimates of precipitation. Based on this, a method to generate ... -
