Global Atmospheric Circulation

About the lecture

In this lecture, we begin our course on tropical cyclones by discussing global atmospheric circulation, a crucial factor determining the occurrence of tropical cyclones. We learn about the structure of the three global atmospheric circulation systems: Polar, Ferrel and Hadley cells, and their roles in global climate patterns such as the Coriolis effect. In addition, we understand the role of the Intertropical Convergence Zone (ITCZ), another crucial factor in the genesis of most tropical cyclones.

About the lecturer

Xiangbo Feng is a senior research scientist at NCAS-Climate (Reading). He researches towards better understanding and predictions of tropical cyclones and associated extremes on different time scales. He collaborates with the UK Met Office, WMO, China and Southeast Asia partners to evaluate dynamical models, and design tailored statistical models if necessary, for tropical cyclone hazards for operational purposes. He is also interested in the underpinning physical processes in tropical cyclones (e.g., precursors, genesis and intensification) and associated extremes. He also has research experience in sea level extremes (storm surge and ocean waves) and data assimilation.
