Zonal Momentum Balance, Potential Vorticity Dynamics, and Mass Fluxes on Near-Surface Isentropes
Publisher: American Meteorological Society
Abstract: While it has been recognized for some time that isentropic coordinates provide a convenient framework for theories of the global circulation of the atmosphere, the role of boundary effects in the zonal momentum balance and ...
The Response of Tropical Climate to the Equatorial Emergence of Spiciness Anomalies
Publisher: American Meteorological Society
Abstract: The ocean?atmosphere response to the surfacing of temperature anomalies from the oceanic thermocline is a key process in climate variability with decadal time scales. Using a coupled general circulation model, it is shown ...
Scale and Rossby Number Dependence of Observed Wind Responses to Ocean-Mesoscale Sea Surface Temperatures
Publisher: American Meteorological Society
Abstract: The horizontal scale dependences of in-phase and lagged imprints of ocean-mesoscale sea surface temperatures on surface winds are investigated using daily AMSR-E radiometer and QuikSCAT scatterometer observations in the ...
The Tropopause and the Thermal Stratification in the Extratropics of a Dry Atmosphere
Publisher: American Meteorological Society
Abstract: A dynamical constraint on the extratropical tropopause height and thermal stratification is derived by considerations of entropy fluxes, or isentropic mass fluxes, and their different magnitudes in the troposphere and ...
Analysis of Incomplete Climate Data: Estimation of Mean Values and Covariance Matrices and Imputation of Missing Values
Publisher: American Meteorological Society
Abstract: Estimating the mean and the covariance matrix of an incomplete dataset and filling in missing values with imputed values is generally a nonlinear problem, which must be solved iteratively. The expectation maximization (EM) ...
The Indonesian Throughflow and the Global Climate System
Publisher: American Meteorological Society
Abstract: The role of the Indonesian Throughflow in the global climate system is investigated with a coupled ocean?atmosphere model by contrasting simulations with realistic throughflow and closed Indonesian passages. The Indonesian ...
A Simplified Model of the Modified Hadley Circulation
Publisher: American Meteorological Society
Abstract: A model is developed to find the low-latitude upper-tropospheric atmospheric circulation which would exist in the absence of transient eddies. The forcing in the model is zonally asymmetric to take into account the effect ...
Noise Control Technology With Reference to Natural Gas Compressor Stations Under the Aspect of Investment Costs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For the conveyance and storage of natural gas, compressor stations are required where the installed power output varies mostly between 1 MW and 20 MW. The noise control measures involved to ...
The Calculation of the Acoustical Quantities of Railway Wheels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of the present investigation is to determine the forced vibrations and acoustical characteristics of a wheel disk with a radially varying thickness from the consideration of ...
