Research Interests

The general circulation of the atmosphere and climate, including midlatitude storm tracks, westerly jets, the Hadley circulation, the tropopause, the Brewer-Dobson circulation, and polar amplification of surface temperature. Other interests include low-frequency variability of large-scale atmospheric flows,  geostrophic turbulence, planetary atmospheres, ocean general circulation, and paleoclimate. To get a better flavor of my research interest, refer to my publications listed in http://www.meteo.psu.edu/~sl.

Teaching Interests

Atmospheric dynamics, physical oceanography, and climate.

Beyond guiding students to learn the fundamental material of the courses that I teach, my primary objective as a teacher is to use the course content as a tool to facilitate the acquirement of life-long learning skills. The most significant challenge in the education of the discipline of geophysical fluid dynamics appears to be the difficulty students have in gaining an intuition for rotating fluids from text books, diagrams, and even the most brilliant computer simulations. In order to address this issue, I use classroom-friendly, laboratory experiments. I make extensive use of these experiments in many of my classes, from freshmen seminar course to graduate-level dynamics classes. 

Graduate Students

I study basic aspects of atmospheric and oceanic phenomena.  Accordingly, my general research approach is to form an hypothesis for a mechanism, and then to test the hypothesis.  As a research tool, I use a hierarchy of numerical models, observations, and analytical approaches.  I also believe that my students enjoy a high level of intellectual freedom in the sense that they are strongly encouraged to challenge my ideas!
