Effects of Tides on Maximum Tsunami Wave Heights: Probability Distributions
(American Meteorological Society, 2007)A theoretical study was carried out to understand how the probability distribution for maximum wave heights (?m) during tsunamis depends on the initial tsunami amplitude (A) and the tides. It was assumed that the total ... -
Sampling Errors in the Measurement of Rainfall Parameters Using the Precipitation Occurrence Sensor System (POSS)
(American Meteorological Society, 2007)The Precipitation Occurrence Sensor System (POSS) is a small Doppler radar originally designed by the Meteorological Service of Canada (MSC) to report the occurrence, type, and intensity of precipitation in automated ... -
The Role of Averaging for Improving Sea Surface Salinity Retrieval from the Soil Moisture and Ocean Salinity (SMOS) Satellite and Impact of Auxiliary Data
(American Meteorological Society, 2007)Soil Moisture and Ocean Salinity (SMOS) was chosen as the European Space Agency?s second Earth Explorer Opportunity mission. One of the objectives is to retrieve sea surface salinity (SSS) from measured brightness temperatures ... -
Direct Estimation of the Reynolds Stress Vertical Structure in the Nearshore
(American Meteorological Society, 2007)Measurements of the vertical Reynolds stress components in the wave-dominated nearshore are required to diagnose momentum and turbulence dynamics. Removing wave bias from Reynolds stress estimates is critical to a successful ... -
Parameterization of Submesoscale Eddy-Rich Flows Using a Stochastic Velocity Model
(American Meteorological Society, 2006)In light of the recent high-resolution radar data of surface velocity, which have revealed submesoscale eddies between the Florida Current and the coast, an objective method of detecting eddies and estimating their parameters ... -
Remote Sensing of Ocean Waves by Polarimetric SAR
(American Meteorological Society, 2006)A new method to measure ocean wave slope spectra using fully polarimetric synthetic aperture radar (POLSAR) data was developed without the need for a complex hydrodynamic modulation transform function. There is no explicit ... -
Dual-Polarization Spectral Analysis for Retrieval of Effective Raindrop Shapes
(American Meteorological Society, 2006)Dual-polarization radar observations of precipitation depend on size?shape relations of raindrops. There are several studies presented in literature dedicated to the investigation of this relation. In this work a new ... -
Metadata from WMO Publication No. 47 and an Assessment of Voluntary Observing Ship Observation Heights in ICOADS
(American Meteorological Society, 2007)It is increasingly recognized that metadata can significantly improve the quality of scientific analyses and that the availability of metadata is particularly important for the study of climate variability. The International ... -
Remote Sensing of Water Cloud Parameters Using Neural Networks
(American Meteorological Society, 2007)In this work a method for determining the micro- and macrophysical properties of oceanic stratocumulus clouds is presented. It is based on the inversion of a radiative transfer model that computes the albedos and brightness ... -
Infrared Thermal Imagery of Cloud Base in Tornadic Supercells
(American Meteorological Society, 2006)During the spring seasons of 2003 and 2004, an infrared thermal camera was deployed in and around supercell thunderstorms in an attempt to retrieve the temperature at the cloud base of a mesocyclone prior to tornadogenesis. ... -
Microwave Radiative Transfer in the Mixed-Phase Regions of Tropical Rainfall
(American Meteorological Society, 2006)Here airborne observations of the mixed-phase regions of tropical oceanic rainfall are reported as part of the Kwajalein Experiment. The University of Washington Convair-580 aircraft carrying upward-viewing 21- and 37-GHz ... -
Algorithms for Density, Potential Temperature, Conservative Temperature, and the Freezing Temperature of Seawater
(American Meteorological Society, 2006)Algorithms are presented for density, potential temperature, conservative temperature, and the freezing temperature of seawater. The algorithms for potential temperature and density (in terms of potential temperature) are ... -
Incremental Analysis Update Implementation into a Sequential Ocean Data Assimilation System
(American Meteorological Society, 2006)This study deals with the enhancement of a sequential assimilation method applied to an ocean general circulation model (OGCM). A major drawback of sequential assimilation methods is the time discontinuity of the solution ... -
Performance of the Vaisala RS80A/H and RS90 Humicap Sensors and the Meteolabor “Snow White” Chilled-Mirror Hygrometer in Paramaribo, Suriname
(American Meteorological Society, 2006)In climate research there is a strong need for accurate observations of water vapor in the upper atmosphere. Radiosoundings provide relative humidity profiles but the accuracy of many routine instruments is notoriously ... -
High-Altitude Cloud Effects on Airborne Electro-Optical Sensor Performance
(American Meteorological Society, 2006)A modeling approach is proposed to predict the impact of high-altitude clouds on the detection performance of an airborne electro-optical surveillance sensor. The sensor is dedicated to target detection, and it may be ... -
Satellite and VIZ–Radiosonde Intercomparisons for Diagnosis of Nonclimatic Influences
(American Meteorological Society, 2006)Radiosonde datasets of temperature often suffer from discontinuities due to changes in instrumentation, location, observing practices, and algorithms. To identify temporal discontinuities that affect the VIZ/Sippican family ... -
Problems with Heavy Snow Data at First-Order Stations in the United States
(American Meteorological Society, 2006)Various interests desire information and data on heavy snowfalls to define their spatial and temporal occurrences. Historical data at the nation?s 208 first-order stations for events with 15.2 cm or more snowfall in 2 days ... -
Nonintrusive Measurement of Ocean Waves: Lidar Wave Gauge
