Impact of Upper-Tropospheric Temperature Anomalies and Vertical Wind Shear on Tropical Cyclone Evolution Using an Idealized Version of the Operational GFDL Hurricane Model

Source: Journal of the Atmospheric Sciences:;2016:;Volume( 073 ):;issue: 010:;page 3803

Author(s): Tuleya, Robert E.; Bender, Morris; Knutson, Thomas R.; Sirutis, Joseph J.; Thomas, Biju; Ginis, Isaac

Publisher: American Meteorological Society

Abstract: he GFDL hurricane modeling system, initiated in the 1970s, has progressed from a research tool to an operational system over four decades. This system is still in use today in research and operations, and its evolution ...

Simulation of the Recent Multidecadal Increase of Atlantic Hurricane Activity Using an 18-km-Grid Regional Model

Source: Bulletin of the American Meteorological Society:;2007:;volume( 088 ):;issue: 010:;page 1549

Author(s): Knutson, Thomas R.; Sirutis, Joseph J.; Garner, Stephen T.; Held, Isaac M.; Tuleya, Robert E.

Publisher: American Meteorological Society

Abstract: In this study, a new modeling framework for simulating Atlantic hurricane activity is introduced. The model is an 18-km-grid nonhydrostatic regional model, run over observed specified SSTs and nudged toward observed ...

Global Projections of Intense Tropical Cyclone Activity for the Late Twenty-First Century from Dynamical Downscaling of CMIP5/RCP4.5 Scenarios

Author(s): Knutson, Thomas R.; Sirutis, Joseph J.; Zhao, Ming; Tuleya, Robert E.; Bender, Morris; Vecchi, Gabriel A.; Villarini, Gabriele; Chavas, Daniel

Publisher: American Meteorological Society

Abstract: lobal projections of intense tropical cyclone activity are derived from the Geophysical Fluid Dynamics Laboratory (GFDL) High Resolution Atmospheric Model (HiRAM; 50-km grid) and the GFDL hurricane model using a two-stage ...

Simulations of the Present and Late-Twenty-First-Century Western North Pacific Tropical Cyclone Activity Using a Regional Model

Source: Journal of Climate:;2014:;volume( 027 ):;issue: 009:;page 3405

Author(s): Wu, Liang; Chou, Chia; Chen, Cheng-Ta; Huang, Ronghui; Knutson, Thomas R.; Sirutis, Joseph J.; Garner, Stephen T.; Kerr, Christopher; Lee, Chia-Jung; Feng, Ya-Chien

Publisher: American Meteorological Society

Abstract: high-resolution regional atmospheric model is used to simulate present-day western North Pacific (WNP) tropical cyclone (TC) activity and to investigate the projected changes for the late twenty-first century. Compared to ...

Dynamical Downscaling Projections of Twenty-First-Century Atlantic Hurricane Activity: CMIP3 and CMIP5 Model-Based Scenarios

Source: Journal of Climate:;2013:;volume( 026 ):;issue: 017:;page 6591

Author(s): Knutson, Thomas R.; Sirutis, Joseph J.; Vecchi, Gabriel A.; Garner, Stephen; Zhao, Ming; Kim, Hyeong-Seog; Bender, Morris; Tuleya, Robert E.; Held, Isaac M.; Villarini, Gabriele

Publisher: American Meteorological Society

Abstract: wenty-first-century projections of Atlantic climate change are downscaled to explore the robustness of potential changes in hurricane activity. Multimodel ensembles using the phase 3 of the Coupled Model Intercomparison ...
