RISStormwater Treatment Effectiveness of Established Lined Bioretention Facilities in Portland, Oregon
Publisher: ASCE
Abstract: Bioretention systems are commonly used to treat and detain stormwater runoff and help mitigate many negative effects of urbanization. The goal of this project is to assess the pollution reduction effectiveness of lined ...
Improvements and Applications in Climate Data Analysis for Determining Reference Rainfall Years
Publisher: American Meteorological Society
Abstract: AbstractInference about time series in weather data can be made in several ways. Current practice focuses on computing summary measures, such as mean and variance, or constructing a reference year from small subsets of ...
Parameterization of Pressure Perturbations in a PBL Mass-Flux Model
Publisher: American Meteorological Society
Abstract: In a companion paper, the authors presented a boundary layer parameterization that was based on the mass-flux concept and included an internally consistent representation of the vertical flux of horizontal momentum. In the ...
A Higher-Order Closure Model with an Explicit PBL Top
Publisher: American Meteorological Society
Abstract: In 2001, the authors presented a higher-order mass-flux model called ?assumed distributions with higher-order closure? (ADHOC 1), which represents the large eddies of the planetary boundary layer (PBL) in terms of an assumed ...
Toward a Unified Parameterization of the Boundary Layer and Moist Convection. Part I: A New Type of Mass-Flux Model
Publisher: American Meteorological Society
Abstract: Higher-order closure (HOC) models have been proposed for parameterization of the turbulent planetary boundary layer (PBL). HOC models must include closures for higher-order moments (e.g., fourth moments in third-order ...
Toward a Unified Parameterization of the Boundary Layer and Moist Convection. Part II: Lateral Mass Exchanges and Subplume-Scale Fluxes
Publisher: American Meteorological Society
Abstract: The dissipation parameterizations developed for higher-order closure are used to parameterize lateral entrainment and detrainment in a mass-flux model. In addition, a subplume-scale turbulence scheme is included to represent ...
Toward a Unified Parameterization of the Boundary Layer and Moist Convection. Part III: Simulations of Clear and Cloudy Convection
Publisher: American Meteorological Society
Abstract: A model that employs a new form of mass-flux closure (described in Part I of this paper) is applied to a variety of clear and cloudy planetary boundary layers (PBLs) including dry convection from the Wangara Experiment, ...
Using Idealized Coherent Structures to Parameterize Momentum Fluxes in a PBL Mass-Flux Model
Publisher: American Meteorological Society
Abstract: In 2001, the authors presented a higher-order mass-flux model called assumed distributions with higher-order closure (ADHOC), which represents the large eddies of the planetary boundary layer (PBL) in terms of an assumed ...
The Effects of Mesoscale Eddies on the Main Subtropical Thermocline
Publisher: American Meteorological Society
Abstract: The effects of mesoscale eddies on the main subtropical thermocline are explored using a simply configured wind- and buoyancy-driven primitive equation numerical model in conjunction with transformed Eulerian mean diagnostics ...
Argon as a Tracer of Cross-Isopycnal Mixing in the Thermocline
Publisher: American Meteorological Society
Abstract: Noble gases such as argon are unaffected by chemical reactions in the ocean interior, but a number of physical mechanisms can lead to measurable sea level atmospheric disequilibrium in subsurface waters of the ocean. One ...
