Throughout my professional career, I have performed research in the field of the boundary-layer meteorology, especially on large-eddy simulations and similarity theory analyses. I have authored over 50 publications in peer-reviewed journals and several books. I published a text-book Structure of the Atmospheric Boundary Layer in 1989 (Prentice Hall). Its second edition will be published at the end of 2010.
I developed a large-eddy simulation model (Sorbjan, 1995), and used it to study :
- diffusion in the nocturnal cloud-topped boundary layer (e.g.,
Sorbjan and Uliasz, 1999), as well as:
- free convection (e.g., Margolin, Smolarkiewicz, Sorbjan,1999; Sorbjan, 2005),
- forced convection (e.g., Sorbjan, 2006),
- baroclinic convection (Sorbjan , 2004),
- the transitory convection (e.g., Sorbjan, 1997; 2007a)
- convection on Mars (Sorbjan, 2007b, c).
I developed parameterizations for the convective boundary layer (Sorbjan, 1996a. b; 2009a), contributed to local similarity theory (Sorbjan, 1986a, b, c), and developed the gradient-based similarity theory (Sorbjan, 2010a, b; Sorbjan and Grachev, 2010). I investigated the stable boundary layer (e.g., Sorbjan, 2006a, b; Sorbjan and Balsley, 2008). I also analyzed Mini-TES data on convection in the Martian Boundary layer (Sorbjan, Wolff, and Smith, 2009b).
