The Extrapolation of Near-Surface Wind Speeds under Stable Stratification Using an Equilibrium-Based Single-Column Model Approach
Publisher: American Meteorological Society
Abstract: lassical approaches to modeling the near-surface (i.e., below 200 m) wind profile are equilibrium based (i.e., no time evolution) and either lack a physical basis or are based on surface-layer physics. In this study, the ...
A Comparison of Equilibrium and Time-Evolving Approaches to Modeling the Wind Profile under Stable Stratification
Publisher: American Meteorological Society
Abstract: n this study, the authors contrast the modeling of the wind profile under stable stratification considering both equilibrium (i.e., constant in time) and time-evolving frameworks, as well as one-dimensional (1D) and 3D ...
The Probability Distribution of Sea Surface Wind Speeds: Effects of Variable Surface Stratification and Boundary Layer Thickness
Publisher: American Meteorological Society
Abstract: Air?sea exchanges of momentum, energy, and material substances of fundamental importance to the variability of the climate system are mediated by the character of the turbulence in the atmospheric and oceanic boundary ...
Can We See the Wind? Statistical Downscaling of Historical Sea Surface Winds in the Subarctic Northeast Pacific
Publisher: American Meteorological Society
Abstract: he statistical predictability of wintertime (December?February) monthly-mean sea surface winds (both vector wind components and wind speed) in the subarctic northeast Pacific off the west coast of Canada is considered, in ...
The Gaussian Statistical Predictability of Wind Speeds
Publisher: American Meteorological Society
Abstract: he statistical predictability of wind speed using Gaussian predictors, relative to the predictability of orthogonal vector wind components, is considered. With the assumption that the vector wind components are Gaussian, ...
The Temporal Autocorrelation Structure of Sea Surface Winds
Publisher: American Meteorological Society
Abstract: he temporal autocorrelation structures of sea surface vector winds and wind speeds are considered. Analyses of scatterometer and reanalysis wind data demonstrate that the autocorrelation functions (acf) of surface zonal ...
Nonlinear Principal Component Analysis by Neural Networks: Theory and Application to the Lorenz System
Publisher: American Meteorological Society
Abstract: A nonlinear generalization of principal component analysis (PCA), denoted nonlinear principal component analysis (NLPCA), is implemented in a variational framework using a five-layer autoassociative feed-forward neural ...
A General Numerical Method for Analyzing the Linear Stability of Stratified Parallel Shear Flows
Publisher: American Meteorological Society
Abstract: he stability analysis of stratified parallel shear flows is fundamental to investigations of the onset of turbulence in atmospheric and oceanic datasets. The stability analysis is performed by considering the behavior of ...
Stabilization of Climate Regimes by Noise in a Simple Model of the Thermohaline Circulation
Publisher: American Meteorological Society
Abstract: Salinity dynamics in a simple two-box model of the thermohaline circulation (THC) is considered. The model parameterizes fluctuating eddy transport and buoyancy forcing by two independent stochastic processes. The associated ...
The Probability Distribution of Sea Surface Wind Speeds. Part I: Theory and SeaWinds Observations
Publisher: American Meteorological Society
Abstract: The probability distribution of sea surface wind speeds, w, is considered. Daily SeaWinds scatterometer observations are used for the characterization of the moments of sea surface winds on a global scale. These observations ...
