    CSTAR Research Updates

    Recorded Research Update on Tropical Cyclone Tornadoes
    Matt Morin

    Updated 2009/03/05

    A recorded presentation from Matt Morin on the CSTAR component investigating Tropical Cyclone Tornadoes is now available. The presentation is 17 minutes in length and includes a brief literature review, discussion of gaps in the TC-tornado knowledge base, and examples of some of his preliminary TC simulation output.

    Web based presentation  |   Microsoft Power Point format

    Matt is looking input on what gaps in the TC-tornado knowledge base is most important or would have the largest impact on the operational community. Your comments and input are appreciated.



    Upcoming Tropical Cyclone Tornadoes Presentation
    Matt Morin

    Updated 2009/02/19

    Goto-meeting update on CSTAR Tropical Cyclone Tornado project scheduled for 3PM, Tuesday March 3, 2009.

    Matt Morin will provide a quick, 30-minute presentation that will include a brief literature review, discussion of gaps in the TC-tornado knowledge base, and examples of some of his preliminary TC simulation output. After the short presentation, they hope to get some feedback from the various forecast offices as to which gaps are most important to the NWS.

    Northwest Flow Snow Events in the Southern Appalachian Mountains
    Updated on 2008/11/01

    This indirectly related CSTAR project is referred to as The Northwest Flow Snowfall Discussion Group

    The Northwest Flow Snowfall Discussion Group was first created following the Fall 2005 CSTAR Regional Workshop held in Raleigh, NC. The group was designed as a "spin-off" of the regional CSTAR group with its primary focus being the specific regional forecast problem of northwest flow snowfall in the Appalachian Mountains. The group meets periodically throughout the year by way of telephone conference to discuss recent/upcoming northwest flow snowfall events, research updates, local modeling efforts, and other notable developments pertinent to the northwest flow snowfall phenomenon.

    The Northwest Flow Snowfall Discussion Group has a separate web site which does an excellent job of providing a central location to access all information that is directly relevant to the group.
