Thursday 11/21 3:30 pm, Foothills Lab 2 Room 1001 Paul Billant and Jean-Marc Chomaz, Ecole Polytechnique, Paris will present: "Instabilities of columnar vortices in stratified and rotating flows" Abstract: We present experiments on the dynamic of a vertical columnar vortex pair in a stratified and rotating fluid. The various 3D instabilities developing on the vortex pair, created by a double flap apparatus, are analyzed as a function of the Froude and Rossby numbers. When the fluid is strongly stratified, a "zigzag" instability slices the vortex pair into thin horizontal layers of pancake dipole. Such instability is expected to be generic and may explain the layering widely observed in pancake turbulence. For Rossby number of order one, two instabilities have been observed to affect solely the anticyclonic vortex: an axisymmetric centrifugal mode and a new asymmetric oscillatory mode. We shall show that this asymmetric instability is also related to the centrifugal instability. For high Rossby and Froude numbers, the elliptic instability arises on both cyclonic and anticyclonic vortices.

Give the greatest Holiday gift you can to the charity of your choice. 2002 has been an unusually tough year for all non-profits, the economic situation has cost dearly in public funding as well as grants and corporate donations. The UCAR Employee Charity Campaign will end on November 30, 2002 for payroll deductions for 2003. Please take a moment and enroll in the campaign before November 30, 2002 if you wish to contribute. Thank you, and of course you are under no obligation to participate.

Wednesday 11/20 at 3:30 pm at Foothills Lab 2, Room 1022 Jean-Marc Chomaz, Ecole Polytechnique, Paris will present: "Instabilities and breakdown in swirling flows and their control" Abstract: Swirling jets or wakes are encountered in many industrial and geophysical flows. They often exhibit violent instabilities (bursting)and may be totally disrupted by vortex breakdown. To understand these phenomena we report results from a swirling jet experiments. In particular a new type of vortex breakdown is presented. Then stability theory allows a proper analysis of the flow and illustrates how centrifugal and shear instability interplay. Finally a physical mechanism for vortex breakdown is proposed based on the inertial wave dynamics and a control strategy is proposed to stabilize the unbroken state.

The Denver-Boulder Chapter of the AMS presents:
Drought and Global Climate Change: Is 2002 a Glimpse of the Future?
by Kevin Trenberth
The atmosphere is global and Colorado's weather and climate are
largely determined by influences from elsewhere. In fact the
atmosphere is a "global commons" and serves as a dumping ground for
pollution from all nations. Air over one nation is half way around
the world a week later, as shown by manned balloon flights. While
rain is a remarkable cleanser of the atmosphere, some gases are not
affected, long-lived and changing our climate. Global warming is
happening. In Colorado, as in other mountain areas, this means more
precipitation falls as rain instead of snow, snow melts sooner, and
there is less snow pack as we go into the summer. Risk of summer
drought increases. With it comes increased heat waves and wildfires.
The summer of 2002 is perhaps a taste of what we can expect more of
in the future? In this talk we will review broad aspects of the 2002
drought and wildfires, and discuss factors that cause drought and
climate change. El Nino and La Nina are factors in interannual
variability, while global warming is a slow but relentless influence
that will emerge more strongly as time goes on. Water will become a
valuable resource.

The UCARFlex 2003 Enrollment Web site is available for employees to make health insurance and flexible spending account selections by Monday, December 2. The link to the web site is below. Use your timecard login and password to access the site. In addition, benefit-eligible employees MUST access the web site to elect their 2003 leave option -- PTO or Traditional Leave. Leave elections must also be made by Monday, December 2. Please access https://www.fin.ucar.edu/hr/internal/Leave_Options.html to read more about the PTO and Traditional Leave options. Please remember that ALL eligible employees must access the site and enroll for next year no matter which plan an employee currently carries. Employees are encouraged to attend an information meeting to learn more about the PTO and Traditional leave plans. The link to the open enrollment meeting schedule can be found within the web site below.

We have reached the final months of 2002 and it's time to think about your Health Care or Dependent Care Flexible Spending Account. You can access updated information about your account with the link below. Remember you have until March 31, 2003 to submit your claims but you must incur all of the expenses in the year 2002. You can find the Flexible Spending Claim form in the Human Resources Forms Library on line at: http://www.fin.ucar.edu/forms/HR/cigna_forms/reim_claim_form.shtml

You are invited to attend an ATD Seminar presented By Graeme Stephens from the Colorado State University on Thursday, 21 November at 10:30am at Foothills Laboratory, Building 2, Auditorium Room 1022. Refreshments will be served . The CloudSat mission and the science to be addressed by the mission will be briefly introduced. Discussion of the unique path-finding aspects of the mission will be tempered by discussion of its limitations. The limitations represent challenges and thus opportunities for further research especially within the context of the constellation of the satellites that form the A-train. The role of CloudSat in the A-train and science opportunities that might be promoted by the A-train observations will be discussed.
For more information, contact Renee Ray at 2050, rray@atd.ucar.edu.
