What Has Changed the Proportion of Intense Hurricanes in the Last 30 Years?
Publisher: American Meteorological Society
Abstract: The recently reported increase in the proportion of intense hurricanes is considerably larger than those projected by the maximum potential intensity (MPI) theory and the results of numerical simulation. To reconcile this ...
Effects of Convective Heating on Movement and Vertical Coupling of Tropical Cyclones: A Numerical Study
Publisher: American Meteorological Society
Abstract: The influence of convective heating on movement and vertical coupling of tropical cyclones (TCs) is investigated using a hurricane model with different environmental flows. The authors identify two processes by which ...
Movement and Vertical Coupling of Adiabatic Baroclinic Tropical Cyclones
Publisher: American Meteorological Society
Abstract: The vertical coupling and movement of an adiabatic baroclinic tropical cyclone (TC) are investigated through two numerical experiments in which the TC is affected by either a vertical environmental shear or a differential ...
Dynamically Derived Tropical Cyclone Intensity Changes over the Western North Pacific
Publisher: American Meteorological Society
Abstract: he study of the impact of global warming on tropical cyclone (TC) intensity is subject to uncertainty in historical datasets, especially in the western North Pacific (WNP) basin, where conflicting results have been found ...
Extended Simulation of Tropical Cyclone Formation in the Western North Pacific Monsoon Trough
Publisher: American Meteorological Society
Abstract: revious studies suggest that the low-frequency background makes an important contribution to the predictability of tropical cyclone (TC) activity on the intraseasonal time scale by providing large-scale conditions favorable ...
Climate Changes of Atlantic Tropical Cyclone Formation Derived from Twentieth-Century Reanalysis
Publisher: American Meteorological Society
Abstract: hereas some studies linked the enhanced tropical cyclone (TC) formation in the North Atlantic basin to the ongoing global warming, other studies attributed it to the warm phase of the Atlantic multidecadal oscillation ...
Assessing Impacts of Global Warming on Tropical Cyclone Tracks
Publisher: American Meteorological Society
Abstract: A new approach is proposed to assess the possible impacts of the global climate change on tropical cyclone (TC) tracks in the western North Pacific (WNP) basin. The idea is based on the premise that the future change of ...
A Potential Vorticity Tendency Diagnostic Approach for Tropical Cyclone Motion
Publisher: American Meteorological Society
Abstract: In order to understand the roles of various physical processes in baroclinic tropical cyclone (TC) motion and the vertical coupling between the upper- and lower-level circulations, a new dynamical framework is advanced. A ...
Synoptic-Scale Influences on Tropical Cyclone Formation within the Western North Pacific Monsoon Trough
Publisher: American Meteorological Society
Abstract: ropical cyclones (TCs) always develop from synoptic-scale disturbances. While early studies suggested that the presence of synoptic-scale disturbances may enhance large-scale conditions for TC formation, recent studies ...
Sudden Track Changes of Tropical Cyclones in Monsoon Gyres: Full-Physics, Idealized Numerical Experiments
Publisher: American Meteorological Society
Abstract: ropical cyclones (TCs) in the eastern semicircle of large-scale monsoon gyres (MGs) were observed to take either a northward (sudden northward and northward without a sharp turn) or a westward TC turn, but only the northward ...
