First Passage Time Analysis on Climate Indices
Publisher: American Meteorological Society
Abstract: Climate variability is simply represented by teleconnection patterns such as the Arctic Oscillation (AO), Antarctic Oscillation (AAO), North Atlantic Oscillation (NAO), Pacific?North American pattern (PNA), and Southern ...
Two Kinds of Predictability in the Lorenz System
Publisher: American Meteorological Society
Abstract: The Lorenz system is used to discuss two kinds of predictability: the model sensitivity to inaccurate initial conditions (first kind) and to inaccurate boundary conditions (second kind). The first kind of predictability ...
Optimal Linear Fitting for Objective Determination of Ocean Mixed Layer Depth from Glider Profiles
Publisher: American Meteorological Society
Abstract: A new optimal linear fitting method has been developed to determine mixed layer depth from profile data. This methodology includes three steps: 1) fitting the profile data from the first point near the surface to a depth ...
Sixth-Order Difference Scheme for Sigma Coordinate Ocean Models
Publisher: American Meteorological Society
Abstract: How to reduce the horizontal pressure gradient error is a key issue of using σ-coordinate ocean models, especially of using primitive equation models for coastal regions. The error is caused by the splitting of the horizontal ...
Accuracy Progressive Calculation of Lagrangian Trajectories from a Gridded Velocity Field
Publisher: American Meteorological Society
Abstract: eduction of computational error is a key issue in computing Lagrangian trajectories using gridded velocities. Computational accuracy enhances from using the first term (constant velocity scheme), the first two terms (linear ...
An Accuracy Progressive Sixth-Order Finite-Difference Scheme
Publisher: American Meteorological Society
Abstract: How to reduce the computational error is a key issue in numerical modeling and simulation. The higher the order of the difference scheme, the less the truncation error and the more complicated the computation. For compromise, ...
A Conserved Minimal Adjustment Scheme for Stabilization of Hydrographic Profiles
Publisher: American Meteorological Society
Abstract: Ocean (T, S) data analysis/assimilation, conducted in the three-dimensional physical space, is a generalized average of purely observed data (data analysis) or of modeled/observed data (data assimilation). Because of the ...
South China Sea Isopycnal-Surface Circulation
Publisher: American Meteorological Society
Abstract: This paper investigates the seasonal variabilities of the South China Sea isopycnal-surface circulations and of the Kuroshio intrusion through the Luzon Strait using the U.S. Navy?s climatological temperature and salinity ...
Ocean Climate Drift and Interdecadal Oscillation Due to a Change in Thermal Damping
Publisher: American Meteorological Society
Abstract: The authors investigate the effect of a change in the rate of thermal damping upon the climate of an ocean general circulation model. Initially, the thermal forcing condition is that proposed by Haney, that is, restoring ...
