Bispectral analysis of geopotential‐height anomalies for synoptic‐intraseasonal time‐scales

Quarterly Journal of the Royal Meteorological Society, 2001
AbstractSpectral decomposition of the third moment of geopotential‐height fluctuations, bispectral analysis, is considered as a convenient and straightforward method of studying the nonlinear three‐wave interactions between spectral constituencies of anomalies.

A Response-Type Road Anomaly Detection and Evaluation Method for Steady Driving of Automated Vehicles

IEEE transactions on intelligent transportation systems (Print), 2022
Serious Road anomalies caused by bridge approach settlement, pavement rutting, etc., not only seriously affect traffic safety and user experience but also aggravate the damage of road structure. It is more relevant to automated vehicles (AVs) as they are

Persistent Positive Anomalies in Geopotential Heights Promote Wildfires in Western North America

Journal of Climate, 2022
Abstract During summer, persistent positive anomalies (PPAs) of midtropospheric geopotential heights in North America are often associated with extreme weather, including heatwaves. We evaluate the link between prolonged summertime PPAs in 500-hPa geopotential heights and wildfire activity across western North America and examine temporal trends in PPA

An Analysis of the Effect of Gravity Anomaly to Height Estimation in High-Precision INS/GNSS Integrated Navigation Systems

IEEE Sensors Journal, 2019
In this paper, we focus on how gravity anomaly affects height estimation in the high-precision inertial navigation system (INS) and global navigation satellite system (GNSS) integration.

Geoid height anomalies over the Cape Verde Rise

Marine Geophysical Researches, 1982
Geoid height anomalies, as determined by satellite altimetry, suggest that the Cape Verde Rise is in local isostatic equilibrium, supported by a low-density root of altered lithosphere. A depth anomaly map shows the Cape Verde Rise to be approximately 1600 km wide and 2km high.

Height of magnetic anomalies

Eos, Transactions American Geophysical Union, 1940
One of the important duties of the United States Coast and Geodetic Survey in recent years has been the preparation of aeronautical charts. On these charts are shown isogonic lines, magnetic azimuths between important cities, or both. Questions have been raised regarding the extent to which magnetic anomalies observed at the surface would ‐affect air ...

Seasonal and low frequency variations in dynamic height anomaly and transport of the Gulf Stream

Oceanographic Literature Review, 1995
One hundred and thirty pairs of hydrographic stations bracketing the Gulf Stream between Cape Hatteras and the New England Seamounts are used to study seasonal and low frequency changes in dynamic height and baroclinic transport.

Persistence of Wintertime 500 mb Height Anomalies over the Central Pacific

Monthly Weather Review, 1985
Abstract The persistence of daily 500 mb geopotential height anomalies during the 17 winters from 1966 to 1982 is documented for a region over the central Pacific that is noted for its frequent blocking activity. Persistence is expressed here in terms of the degree to which a height value remains constant during the next several days.

Antarctic sea‐ice variation associated with vertical geopotential height and temperature anomalies

International Journal of Climatology, 2019
AbstractIt is well‐known that the increasing zonal‐mean trend of sea‐ice concentration (SIC) surrounding Antarctica is up to 2015 so this paper first summarized this trend with opposing regional trends in each season along the latitude band 60°–70°S during 1979–2015. The surface wind trends can partly explain the observed regional SIC trends.
