[NEIU Physics Students] Friday Seminar

[Gregory Anderson]

Dear Students and Faculty,

  This Friday's Mathematical Sciences Seminar will be given by Dr.
Johnny Lin from North Park University.

   Towards Stochastic Deep Convective Parameterization

   Convective parameterizations used in general circulation models 
   (GCMs) generally only simulate the mean or first-order moment of 
   convective ensembles and do not explicitly include higher-order 
   moments.  The influence of including unresolved higher-order moments 
   is investigated using stochastic deep convective parameterization.
   Impacts are tested in an tropical atmospheric model of intermediate
   complexity as well as a comprehensive GCM.  Adding convective noise 
   noticeably affects tropical intraseasonal variability, suggesting 
   inclusion of such noise in GCMs might be beneficial.  Model response 
   to the noise is sensitive not only to the noise amplitude, but also 
   to such particulars of the stochastic parameterization as 
   autocorrelation time and interaction with model dynamics.
