The M2 Cotidal Chart in the Bohai, Yellow, and East China Seas from Dynamically Constrained Interpolation
(American Meteorological Society, 2020)The harmonic constants extracted from tidal gauge stations and satellite altimeter observations are usually sparsely distributed in the continental marginal seas, but they are precious data for addressing the main ... -
Mechanism of Cloud Droplet Motion under Sound Wave Actions
(American Meteorological Society, 2020)Sound waves have proven to be effective in promoting the interaction and aggregation of droplets. It is necessary to theoretically study the motion of particles in a sound field to develop new acoustic technology for ... -
Optimizing Mooring Placement to Constrain Southern Ocean Air–Sea Fluxes
(American Meteorological Society, 2020)Proposals from multiple nations to deploy air–sea flux moorings in the Southern Ocean have raised the question of how to optimize the placement of these moorings in order to maximize their utility, both as contributors to ... -
Impacts of the Phase Shift between Incident Radar Waves on the Polarization Variables from Ice Cloud Particles
(American Meteorological Society, 2020)The impacts of the differential phase of incident radar waves (ψi) on measured differential reflectivity (ZDR), differential phase, and correlation coefficient from ice cloud particles are presented for radars employing ... -
The Track and Accompanying Sea Wave Forecasts of the Super Typhoon Mangkhut (2018) by a Real-time Regional Forecast System
(American Meteorological Society, 2020)The track and accompanying sea wave forecasts of the typhoon Mangkhut (2018) by a real-time regional forecasting system are assessed in this study. The real-time regional forecasting system shows a good track forecast skill ... -
Using Spectrograms from Underwater Total Pressure Sensors to Detect Passing Vessels in a Coastal Environment
(American Meteorological Society, 2020)Monitoring vessel traffic in coastal regions is a key element of maritime security. For this reason, additional ways of detecting moving vessels are explored by using the unique structure of their wake waves based on ... -
Sounding Characteristics that Yield Significant Convective Inhibition Errors due to Ascent Rate and Sensor Response of In Situ Profiling Systems
(American Meteorological Society, 2020)Accurate measurements of the convective inhibition (CIN) associated with capping inversions are critical to forecasts of deep convection initiation. The goal of this work is to determine the sounding characteristics most ... -
CloudA: A Ground-Based Cloud Classification Method with a Convolutional Neural Network
(American Meteorological Society, 2020)Conventional classification methods are based on artificial experience to extract features, and each link is independent, which is a kind of “shallow learning.” As a result, the scope of the cloud category applied by this ... -
A Spherical Temperature Sensor Array Design for Near-Surface Atmospheric Temperature Studies
(American Meteorological Society, 2020)The observation accuracy of the surface air temperature less than 0.1 K is a requirement, stated by the meteorological and climatological community. However, the accuracy of a temperature sensor inside a shield is affected ... -
An Expanded Batch-to-Batch Correction for IAPSO Standard Seawater
(American Meteorological Society, 2020)We expanded the batch-to-batch offsets of The International Association for the Physical Sciences of the Oceans (IAPSO) Standard Seawater (SSW) batches P145–P163 by intercomparison measurements using salinometers. On the ... -
Long-Autonomy Unmanned Aircraft Vehicle (UAV) for Quick Release of Ocean Minidrifters
(American Meteorological Society, 2020)In this work we present an unmanned aircraft vehicle (UAV) designed from off-the-shelf components to release ocean minidrifters. Its endurance (~1 h), payload (~5 kg), offshore range (~30 km), capability of operating into ... -
