If you happen to be in Brisbane you might like to attend:


Tropical Cyclone Intensification: A Review
5:00pm, Thursday 2 February
Bureau of Meteorology
Level 21, 69 Ann St, Brisbane

The Bureau of Meteorology Brisbane Office and the AMOS Brisbane Centre invite you to a presentation by Professor Roger Smith (Ludwig-Maximilians University of Munich, Germany):

Roger will review recent research on the formation and intensification of tropical cyclones. He will focus on the physical ideas and recent new insights. The presentation will provide a unified view of tropical cyclogenesis and tropical cyclone intensification, which are often treated as separate processes. Cyclonegenesis involves rotating deep convection in lower tropospheric converging absolute vorticity to increase the tangential winds. Observations and modelling shows that the spinup of the maximum tangential wind occurs in the layer of strong frictionally-induced inflow in the boundary layer. This possible counter-intuitive result is explained. Recent numerical simulations show that the classical axisymmetric paradigm for tropical cyclone spinup primarily explains the winds beyond the eyewall, while the eyewall region itself is spun up by the combined transport of friction layer momentum and rotating clouds.

Refreshments will be served afterwards.

If you wish to attend this event, please RSVP to Michael Hewson (m.hewson at cqu.edu.au<mailto:m.hewson at cqu.edu.au>) as soon as possible.
