Estimating Surface Divergence of Ocean Eddies Using Observed Trajectories from a Surface Drifting Buoy
(American Meteorological Society, 2009)A method is described that estimates the time evolution of surface divergence and other secondary circulation properties of an ocean eddy. The method is novel because it is applied to the observations of a single surface ... -
An Empirical Model for Estimating the Geographic Location of Nonlinear Internal Solitary Waves
(American Meteorological Society, 2009)This paper describes the development and performance of a new approach for estimating the geographic location of high-frequency nonlinear internal waves. The approach makes use of the internal wave signatures recorded in ... -
Two-Way Particle-Tracking Model for Specifying Sources of Drifting Objects: Application to the East China Sea Shelf
(American Meteorological Society, 2009)The two-way Lagrangian particle-tracking model (PTM) is proposed for specifying sources of objects drifting with random-walk processes on the sea surface. First, to determine object source candidates, modeled particles are ... -
Data Sensitivity of the ECCO State Estimate in a Regional Setting
(American Meteorological Society, 2009)The Estimating the Circulation and Climate of the Ocean (ECCO) consortium provides a framework in which the adjoint method of data assimilation is applied to a general circulation model to provide a dynamically self-consistent ... -
Interpolation of Tidal Levels in the Coastal Zone for the Creation of a Hydrographic Datum
(American Meteorological Society, 2010)As part of the U.K. Hydrographic Office (UKHO)-sponsored Vertical Offshore Reference Frames (VORF) project, a high-resolution model of lowest astronomical tide (LAT) with respect to mean sea level has been developed for ... -
Measuring Storm Surge with an Airborne Wide-Swath Radar Altimeter
(American Meteorological Society, 2009)Over the years, hurricane track forecasts and storm surge models, as well the digital terrain and bathymetry data they depend on, have improved significantly. Strides have also been made in the knowledge of the detailed ... -
Observation of Wave Energy Evolution in Coastal Areas Using HF Radar
(American Meteorological Society, 2009)The capability of phased-array HF radar systems to sample the spatial distribution of wave energy is investigated in different storm scenarios and coastal configurations. First, a formulation introduced by D. E. Barrick ... -
An Evaluation of χT Estimation Techniques: Implications for Batchelor Fitting and ε
(American Meteorological Society, 2009)Techniques for the accurate estimation of the dissipation rate of temperature variance ?T from temperature microstructure measurements are synthesized and evaluated. The techniques focus on the treatment of contamination ... -
A Fourier-Based Method for the Distribution of Breaking Crests from Video Observations
(American Meteorological Society, 2009)A Fourier-based method is presented to process video observations of water waves and calculate the speed distribution of breaking crest lengths. The method has increased efficiency and robust statistics compared with ... -
Assimilating Altimetry Data into a HYCOM Model of the Pacific: Ensemble Optimal Interpolation versus Ensemble Kalman Filter
(American Meteorological Society, 2009)The ensemble Kalman filter (EnKF) has proven its efficiency in strongly nonlinear dynamical systems but is demanding in its computing power requirements, which are typically about the same as those of the four-dimensional ... -
The Evaluation of CloudSat and CALIPSO Ice Microphysical Products Using Ground-Based Cloud Radar and Lidar Observations
(American Meteorological Society, 2010)In this paper, the statistical properties of tropical ice clouds (ice water content, visible extinction, effective radius, and total number concentration) derived from 3 yr of ground-based radar?lidar retrievals from the ... -
Blending Sea Surface Temperatures from Multiple Satellites and In Situ Observations for Coastal Oceans
(American Meteorological Society, 2009)A two-dimensional variational data assimilation (2DVAR) method for blending sea surface temperature (SST) data from multiple observing platforms is presented. This method produces continuous fields and has the capability ... -
A New Algorithm for Finding Mixed Layer Depths with Applications to Argo Data and Subantarctic Mode Water Formation
(American Meteorological Society, 2009)A new hybrid method for finding the mixed layer depth (MLD) of individual ocean profiles models the general shape of each profile, searches for physical features in the profile, and calculates threshold and gradient MLDs ... -

Corrections for Temporal Discontinuities in the OPI
(American Meteorological Society, 2010)The longest record of precipitation estimated from satellites is the outgoing longwave radiation (OLR) precipitation index (OPI), which is based on polar-orbiting infrared observations from the Advanced Very High Resolution ... -
The Unit Symbol for the Logarithmic Scale of Radar Reflectivity Factors
(American Meteorological Society, 2010)This note argues that the proper symbol for the logarithmic unit of radar reflectivity factor is dBz. The basis for this contention lies in both customary engineering practice and the international standard for unit symbols. -
The Varying Response of Microwave Signatures to Different Types of Overland Rainfall Found over the Korean Peninsula
