Monthly mean vertical motions over the Pacific Ocean
It is the purpose of this paper to compare vertical velocity with satellite observed cloud distribution in the tropics, especially with (1) the intertropical maximum cloud band in the Northern Hemisphere paralleling the equator and about 5 degrees north of it throughout the year, (2) the occurrence …

Exploring methods to extract vertical motions in winter storms
Methods of retrieving vertical motions in wintertime cyclones are tested for the 915 MHz profiler, a profiling radar on the University of Alabama-Huntsville Mobile Integrated Profiling System, used during several winter cyclones observed during the Profiling of Winter Storms (PLOWS) project. First, …

Vertical Motions at the Fringes of the Icelandic Plume
The Icelandic mantle plume has had a profound influence on the development of the North Atlantic region over its 64 Myr existence. Long-wavelength free-air gravity anomalies and full waveform tomographic studies suggest that the planform of the plume is highly irregular, with up to five fingers of …

Manoeuvring behaviour of ships in extreme astern seas
… and effective numerical tools concerning ship motions in astern seas, this thesis presents the development of a coupled non-linear 6-DOF model with frequency dependent coefficients, incorporating memory effects in random waves with a new axis system that allows straightforward combination …

Climatic and geodynamic influences on ocean island geomorphology
… constrain their age, initial topography, and vertical motions relative to sea level, volcanic ocean islands provide an exceptional natural experiment in landscape evolution. Analyses traversing gradients in island climate and bedrock age have the potential to advance our understanding of …

Vibration Isolation of a Horizontal Rigid Plate Supported by Pre-bent Struts
… excitation, making it ideal for isolating vertical vibrations. In this research, four of these vibration isolators are used to support a rigid, square plate. The symmetric case is analyzed first. Then the plate has a center of mass which is located at some distance from the geometric center …

Orographic Precipitation Over the Island of Oahu
… demonstrate the relationship between orographic vertical motion and precipitation, a linear diagnostic upslope model has been developed to provide a high-resolution picture of terrain induced vertical motion and precipitation over the Island of Oahu. The model is called the Hawaiian Orographic …

Slamming of High Speed Craft: A Parametric Study of Severe Cases
… were designed to be an intermediate step between vertical water entry tests of a wedge and a traditional tow tank experiment of a planning hullform in waves. This allowed a deeper study of the hydrodynamic loads that occur during slamming. A planing hull model was subjected to controlled motions …

Environmental dependence of mass-dimension relationships and investigation of microphysical observations of a southern hemisphere atmospheric river
… structures, microphysical processes, and vertical motions observed within the atmospheric river could offer potential areas of model improvement by comparing simulations of these systems to observations made during flight.

A Fail-safe, Bi-Linear Liquid Spring, Controllable Magnetorheological Fluid Damper for a Three-dimensional Earthquake Isolation System
… buildings are susceptible to damage from vertical motions. In this study, a fail-safe, bi-linear liquid spring, controllable magnetorheological (MR) damper is designed, built and tested. The device combines the controllable MR damping in addition to the fail-safe viscous damping and liquid …

Um estudo sobre a influência de fenômenos metereológicos extratropicais na variação do clima do nordeste
… of the Northeast region. At the 500 mb level vertical motions were observed more (less) intense near the Northeast coast and the norther part of the region for the rainy (dry) case.

Laramide transpression and oblique thrusting in the northeastern Front Range, Colorado: 3D kinematics of the Livermore Embayment
… hypotheses for the area invoking a dominance of vertical motions during Laramide deformation. Variable σ1 trends at individual locations provide evidence for strain partitioning and vertical axis rotation within E-, and NE-trending transpressional structures. Relative-timing relationships of …

Time domain simulation of hydroelastic response of ships in large amplitude waves
The influence of non-linearities on wave-induced motions and loads has been the focus of many investigations in the past few years and continues to be an important issue. A number of two- and three-dimensional methodologies have been developed, by and large, partly accounting for various …

Boundary layer temporal evolution observed by doppler lidar upwind of a lake-effect snow event
… the boundary layer using statistical values of vertical motions for each time step of data collection is developed. The approximations made for the top of the boundary layer at specific time intervals were then plotted as a time series. This time series was the skeleton for the final conceptual …

Dynamics of a vertically tethered marine platform
… and tension measurements were made of a typical vertically tethered system, a caged deep-sea ROV, while it operated at sea. The system is essentially one-dimensional because only the vertical motions of the underwater platform and the ship were coherent, while horizontal motions of the platform …

Global Analysis of Predicted and Observed Dynamic Topography
… peninsula grew principally in Neogene times with vertical motions linked to asthenospheric temperature anomalies. Uplift rates of up to 0.1 mm a$^{-1}$ place important constraints on the spatio-temporal evolution of dynamic topography and suggest that rates of transient vertical motion exceed …

Understanding topographic evolution of continents with landscape evolution simulations: the case of North America
… proposed mechanisms of continental-scale vertical motions can be categorized into: 1) isostatic topographic variation due to changes in lithospheric buoyancy, and 2) dynamic topography driven by flow within the sub-lithospheric mantle. Here I use landscape evolution simulations to …
