Transcription de la présentation

  1. Convective Hotspot Method • Review of Effort • Initial simulations –> Change Surface Albedo • Idea was to have solar heating drive convection • Great idea, real world is more complicated! • Clouds formed in area of hot spot quenched the solar heating. • Initial test region included a lake which stayed hot! • Current Approach • Create a (very) hot lake! • Lake temperatures tested thus far: • 335K (143F), 350K (170F), 365K (197F), 380K (224F)

  2. Convective Hotspot Method • Current Approach • Create a (very) hot lake! • Interesting results for the three “cooler” lake temperatures tested thus far • A boiling lake [380K (224F)] didn’t work (yet?) • Still a bit too simple for controlling intensity. • Coming simulations will look at thermodynamic state in a region • Perhaps CAPE or Lifted Index as an approximation of forced convection intensity

  27. Next Steps • Code is written to work on arbitrary size domain • Arbitrary location of hot spot is next • Development of throttling capability is being pondered. • WRF needs to be installed and tested on Solaris system • User interface for creating simulation needs to be designed and built (year 2).
