### Tropical Atmospheric Waves: theory, asymptotic methods and open problems of relevance to the climate system.

**Student-Run Applied & Math Seminar**

Speaker: | Joseph Biello, UC Davis |

Location: | 1147 MSB |

I will present some observations regarding large scale phenomena in the tropical atmosphere. These are essentially large scale waves with a lot of small scale behavior embedded in them. The objective of my research is to try to understand these waves by making simplified models which are derived in a systematic fashion from first principles - i.e. the equations of fluid dynamics. This systematic method is called "multiscale asymptotic analysis" and I will show how we used such a procedure to derive simplified equations for 2 such phenomena. I will also talk about open problems in the field which students can be involved in - and for which funding is available to students.
