I study the weather-chemistry-climate coupling between the stratosphere and troposphere using satellite observations and global climate models. My work focuses on the large-scale circulations and their impacts on the atmospheric composition, and how variation of trace constituents, in turn, impact the climate and chemistry.
ATOC 1060 - Our Changing Environment: El Nino, Ozone, and Climate
Primary Instructor
-
Spring 2025 / Fall 2025
Discusses the Earth's climate for nonscience majors, focusing on the role of the atmosphere, oceans, cryosphere and land surface. Describes the water cycle, atmospheric circulations and ocean currents, and how they influence global climate, El Nino and the ozone hole. Discusses human impacts from climate change. Recommended prerequisite: ATOC 1050.
ATOC 3600 - Principles of Climate
Primary Instructor
-
Fall 2023 / Fall 2024
Describes the basic components of the climate system: the atmosphere, ocean, cryosphere and lithosphere. Investigates the basic physical processes that determine climate and link the components of the climate system. Covers the hydrological cycle and its role in climate, climate stability and global change. Recommended prerequisites: one semester of calculus and ATOC 1060 or ATOC 3300 or GEOG 3301 or GEOG 1001 or ATOC major. Same as GEOG 3601 and ENVS 3600.
ATOC 5060 - Dynamics of the Atmosphere and Oceans
Primary Instructor
-
Spring 2026
Examines large-scale motions in a stratified rotating atmosphere and ocean, and quasi-geostrophic flow, barotropic and baroclinic instabilities, cyclogenesis, global circulations and boundary layer processes. Ageostrophic motions, including Kelvin waves, internal gravity waves and the theory of frontogenesis are also considered. Recommended prerequisite: ATOC 5050, one year of calculus-based physics and math up through differential equations. ATOC graduate core course.

Fall 2025
Studies an area of current research in the atmospheric and oceanic sciences. Students read selected papers from the literature. Students and faculty give presentations and participate in discussions. May be repeated for a total of 6 credit hours within the degree. May be repeated for a total of 3 credit hours within a semester.
