RISSea Surface Temperature Thresholds for Tropical Cyclone Formation
Publisher: American Meteorological Society
Abstract: lmost 70 years ago a sea surface temperature (SST) threshold of 26°?27°C, below which tropical cyclones (TCs) did not form, was proposed, based on a qualitative assessment of warm-season global SST and known TC formation ...
Pyrocumulonimbus Firepower Threshold: Assessing the Atmospheric Potential for pyroCb
Publisher: American Meteorological Society
Prediction and Diagnosis of Tropical Cyclone Formation in an NWP System. Part I: The Critical Role of Vortex Enhancement in Deep Convection
Publisher: American Meteorological Society
Abstract: This is the first of a three-part investigation into tropical cyclone (TC) genesis in the Australian Bureau of Meteorology?s Tropical Cyclone Limited Area Prediction System (TC-LAPS), an operational numerical weather ...
A Model Investigation of the Dynamics of a Coastally Trapped Disturbance
Publisher: American Meteorological Society
Abstract: Numerical simulations of the 15?17 May 1985 coastally trapped disturbance (CTD) event along the west coast of North America are compared with the schematic model of CTD evolution developed by Skamarock, Rotonno, and Klemp ...
Prediction and Diagnosis of Tropical Cyclone Formation in an NWP System. Part III: Diagnosis of Developing and Nondeveloping Storms
Publisher: American Meteorological Society
Abstract: This is the third of a three-part investigation into tropical cyclone (TC) genesis in the Australian Bureau of Meteorology?s Tropical Cyclone Limited Area Prediction System (TC-LAPS), an operational numerical weather ...
Sensitivity of Coastally Trapped Disturbance Dynamics to Barrier Height and Topographic Variability in a Numerical Model
Publisher: American Meteorological Society
Abstract: The sensitivity of a coastally trapped disturbance (CTD) to topographic height is examined using simulations of the 15?18 May 1985 CTD. These simulations include three with uniform topography, in which the North American ...
A Numerical Study of a Southeast Australian Coastal Ridging Event
Publisher: American Meteorological Society
Abstract: A numerical study of the 9?11 November 1982 southeast Australian coastal ridging event is presented. The mesoscale coastal features of this event have been previously described as a coastally trapped disturbance (CTD). ...
Prediction and Diagnosis of Tropical Cyclone Formation in an NWP System. Part II: A Diagnosis of Tropical Cyclone Chris Formation
Publisher: American Meteorological Society
Abstract: This is the second of a three-part investigation into tropical cyclone (TC) genesis in the Australian Bureau of Meteorology?s Tropical Cyclone Limited Area Prediction System (TC-LAPS). The primary TC-LAPS vortex enhancement ...
On the Use of Potential Vorticity Tendency Equations for Diagnosing Atmospheric Dynamics in Numerical Models
Publisher: American Meteorological Society
Abstract: his study critically assesses potential vorticity (PV) tendency equations used for analyzing atmospheric convective systems. A generic PV tendency format is presented to provide a framework for comparing PV tendency ...
Projected Changes in Late-Twenty-First-Century Tropical Cyclone Frequency in 13 Coupled Climate Models from Phase 5 of the Coupled Model Intercomparison Project
Publisher: American Meteorological Society
Abstract: hanges in tropical cyclone (TC) frequency under anthropogenic climate change are examined for 13 global models from phase 5 of the Coupled Model Intercomparison Project (CMIP5), using the Okubo?Weiss?Zeta parameter (OWZP) ...
