Book excerpt: ABSTRACT: Radial momentum budgets were performed to elucidate the mechanisms responsible for the formation of the physically significant secondary circulation. Results show that explicit (sub-grid) diffusion in the model was producing a gradient wind imbalance, which drives a radial inflow and associated secondary circulation in an attempt to re-gain balance. In addition, the production of vorticity anomalies from the asymmetric heating was found to be sensitive to the eddy diffusivity, with large differences between HIGRAD and the widely used WRF model for the exact same value of this uncertain parameter.

This book was released on 2012 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Airborne Doppler radar observations of the stationary rainband complex and secondary eyewall in Hurricane Rita (2005) were analyzed to better understand the inner-core dynamics of tropical cyclones. In the upwind end of the rainband complex, convective cells displayed kinematic structures that varied with radius. Cells at smaller radii contained a low-level tangential jet constrained in altitude largely by tangential acceleration due to angular momentum conservation, while cells at larger radii contained a low-level and/or midlevel jet determined jointly by angular momentum conservation and vertical advection. These variations are attributable to vortex-scale dynamics in which convective buoyancy (associated with vertical advection) and vertical shear of the radial wind (associated with angular momentum conservation) change with radius. With jets constrained to low altitudes, inner cells are more likely to increase low-level convergence and amplify convection, possibly influencing the formation of a secondary eyewall. In the downwind end of the rainband complex, collapsing convective cells formed a mesoscale stratiform rainband that contained rising radial outflow within the stratiform cloud layer. Below the cloud layer, descending radial inflow was driven by horizontal buoyancy gradients, and thus horizontal vorticity generation, introduced by regions of sublimational and melting cooling. This inflow advected higher angular momentum inward, which resulted in the development of a midlevel tangential jet and broadening of the tangential wind field. This circulation may have also contributed to ventilation of the eyewall as inflow of low-entropy air continued past the rainband in both the boundary layer and midlevels. The stationary rainband complex soon evolved into a secondary eyewall, consisting of a ring of heavy precipitation outside the pre-existing eyewall. Enhanced radial outflow was located just above the boundary layer which modified the deeper overturning circulation of the secondary eyewall. This outflow was associated with a low-level tangential wind maximum which was strongly supergradient, mimicking the low-level circulation of the primary eyewall. Axisymmetric and asymmetric processes contributed comparably to strengthening the secondary eyewall tangential wind maximum. The evolution of these inner-core features likely played an important role in modifying the structure and intensity of the total vortex.

Download or read book Dynamics and Predictability of Tropical Cyclones Evaluated Through Convection permitting Ensemble Analyses and Forecasts with Airborne Radar and Sounding Observations written by Erin Munsell and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The dynamics and predictability of various aspects of tropical cyclone track and intensity forecasting are explored through the use of real-time convection-permitting ensemble forecasts generated by a regional-scale model that employs advanced data assimilation techniques. Airborne Doppler radar observations, as well as sounding observations gathered during NASAs Hurricane and Severe Storm Sentinel (HS3) are assimilated and the resulting sensitivity and uncertainty of divergent track and intensity forecasts for three Atlantic tropical cyclones (TCs; Hurricane Sandy (2012), Hurricane Nadine (2012), and Hurricane Edouard (2014)) are explored. Ensemble members are separated into groups according to their performance and composite analyses and ensemble sensitivity techniques are employed to diagnose the sources of greatest sensitivity and uncertainty, as well as to dynamically explain the divergent behavior observed in the forecasts.The analysis of the Hurricane Sandy (2012) ensemble reveals that the divergent track forecasts result from differences in the location of Sandy that develop over the first 48-h of the simulation as a result of variance in the strength of the environmental winds that Sandy is embedded in throughout this period. Disparities in the strength and position of an approaching mid-latitude trough yield divergence in track forecasts of Hurricane Nadine (2012); an increased interaction between the mid-latitude system and the TC steers Nadine eastward, while a reduced interaction allows the TC to be steered westward ahead of the approaching trough. In addition, the inclusion of 6-h sea surface temperature (SST) updates considerably improves Nadines intensity forecasts, highlighting the importance of accurate SST fields when simulating TCs embedded in marginally favorable environmental conditions. Finally, considerable variance in the rapid intensification (RI) onset time in the Hurricane Edouard (2014) ensemble results from small distinctions in the magnitude of deep-layer shear prior to RI, which contributes to differences in the vortex tilt magnitude, the strength and location of the inner-core convection associated with the developing vortex, and the subsequent precession process.

Book excerpt: Tropical cyclones are a major threat to life and property, even in the formative stages of their development. They include a number of different hazards that individually can cause significant impacts, such as extreme winds, storm surge, flooding, tornadoes, and lightning. Tropical Cyclones: Observations and Basic Processes provides a modern overview of the theory and observations of tropical cyclone structure and behavior. The book begins by summarizing key observations of the structure, evolution, and formation of tropical cyclones. It goes on to develop a theoretical foundation for a basic understanding of tropical cyclone behavior during the storm’s life cycle. Horizontally two-dimensional dynamics of vortex motion and other non-axisymmetric features are considered first before tackling the axisymmetric balance dynamics involving the overturning circulation. Following a review of moist convective processes, later chapters focus mainly on a range of three-dimensional aspects of the tropical cyclone life cycle. Building from first principles, the book provides a state-of-the-art summary of the fundamentals of tropical cyclones aimed at advanced undergraduates, graduate students, tropical meteorologists, and researchers.
