Measurement of Cloud Perturbation Pressures Using an Instrumented Aircraft
(American Meteorological Society, 2012)ertical accelerations during the early stages of convective cloud formation are often the result of buoyancy and the perturbation vertical pressure gradient forces. Convection modifies the local pressure field surrounding ... -
Use of Altimeter and Wind Data to Detect the Anomalous Loss of SVP-Type Drifter’s Drogue
(American Meteorological Society, 2012)he study presented in this paper is motivated by the unexplained time dependency of the Ekman model recently computed by Rio et al. using a dataset of ?drogued? drifting buoy velocities distributed by the Surface Drifter ... -
A Methodology for the Characterization of Periodicities in Nonsteady Time Series: Application to Tropospheric Ozone Recharging Cycles in the Western Mediterranean Basin
(American Meteorological Society, 2012)nvironmental measurements often show unsteady variability and background red noise (stochastic component) superimposed on persistent trivial daily, seasonal, and annual variability. In addition to this, environmental time ... -
A Velocity Dealiasing Scheme for Synthetic C-Band Data from China’s New Generation Weather Radar System (CINRAD)
(American Meteorological Society, 2012)velocity dealiasing algorithm is developed for C-band (5-cm wavelength) Doppler radars. With the shorter wavelength, C-band radars operating in a single PRF mode have a Nyquist interval about one-half that of S-band radars. ... -
Modeling the Radar Signature of Raindrops in Aircraft Wake Vortices
(American Meteorological Society, 2012)he present work is dedicated to the modeling and simulation of the radar signature of raindrops within wake vortices. This is achieved through the computation of the equation of raindrop motion within the wake vortex flow. ... -
Current Patterns in the Inner Sound (Pentland Firth) from Underway ADCP Data
(American Meteorological Society, 2012)umerous acoustic Doppler current profiler (ADCP) surveys were performed in the Inner Sound of the Pentland Firth, a channel between the Orkney Islands and the northern coast of Scotland connecting the Atlantic Ocean to the ... -
Improved Reconstruction of Global Precipitation since 1900
(American Meteorological Society, 2012)n improved land?ocean global monthly precipitation anomaly reconstruction is developed for the period beginning in 1900. Reconstructions use the available historical data and statistics developed from the modern satellite-sampled ... -
Two-Component Horizontal Aerosol Motion Vectors in the Atmospheric Surface Layer from a Cross-Correlation Algorithm Applied to Scanning Elastic Backscatter Lidar Data
(American Meteorological Society, 2012)wo-component horizontal motion vectors of aerosol features were calculated by applying a cross-correlation algorithm to square image blocks extracted from consecutive pairs of elastic backscatter lidar scans. The resulting ... -
A Behavioral Probabilistic Risk Assessment Framework for Managing Autonomous Underwater Vehicle Deployments
(American Meteorological Society, 2012)he deployment of a deep-diving long-range autonomous underwater vehicle (AUV) is a complex operation that requires the use of a risk-informed decision-making process. Operational risk assessment is heavily dependent on ... -
Implementation of Real-Time Quality Control Procedures by Means of a Probabilistic Estimate of Seawater Temperature and Its Temporal Evolution
(American Meteorological Society, 2012)ear-real-time quality control procedures for temperature profiles collected from ships of opportunity were implemented during the 1980s in oceans across the world and from the 1990s in the Mediterranean. In this sea, the ... -
Underwater Radiance Distributions Measured with Miniaturized Multispectral Radiance Cameras
(American Meteorological Society, 2012)iniaturized radiance cameras measuring underwater multispectral radiances in all directions at high-radiometric accuracy (CE600) are presented. The camera design is described, as well as the main steps of its optical and ... -
The Gradient Velocity Track Display (GrVTD) Technique for Retrieving Tropical Cyclone Primary Circulation from Aliased Velocities Measured by Single-Doppler Radar
(American Meteorological Society, 2012)he ground-based velocity track display (GBVTD) technique was developed to estimate the primary circulations of landfalling tropical cyclones (TCs) from single-Doppler radar data. However, GBVTD cannot process aliased Doppler ... -
Accounting for the Solar Radiation Influence on Downward Longwave Irradiance Measurements by Pyrgeometers
(American Meteorological Society, 2012)easurements of broadband downward longwave (LW) irradiance are carried out at Lampedusa, Italy, in the Mediterranean, jointly with solar irradiance, since 2004 using shaded and unshaded Eppley Precision Infrared Radiometers ... -
