Going With The Flow: Professor Bill Boos

Bill Boos started out as a physics guy at a big public institution (SUNY-Binghamton) and that’s the way he still sees himself. He’s a professor in Earth & Planetary Science here at UC Berkeley now, but “earth science is physics, just with a particular focus.” Boos’ research focuses on large-scale climate dynamics—how atmospheric circulations, ocean interactions, radiative transfer, and land surface processes control regional and global climate. He helps discover how the world around us works, and he gets there through careful theory and analysis rooted in hard data—hard as rocks.

While doing a Master’s at MIT, Boos’ advisor proffered three possible topics, and the third—hurricanes in the tropics--was so captivating that he was hooked and has stayed on the topic of climate dynamics now for over twenty years. Hurricanes do more than damage the region they pass over; they can have worldwide effects. How local phenomena influence the distribution of water throughout the atmosphere at a planetary scale is one of the central unresolved problems of EPS. This is especially true for extreme weather events that happen in the tropics, such as monsoons. For the past decade or so researchers in this field, including Prof. Boos, have been sorting out the details of dynamic flows in the tropics, partially because the temperate latitudes have largely been successfully analyzed already.

Professor Boos’ own dynamism comes out in the classroom. He has a warm yet direct teaching style that does more than transmit information and clarify study materials. He sets the scene so that students can safely exercise their developing reasoning skills. It’s a practical approach that has seemingly magical effects. He presents thought experiments and news items with no bias favoring anything but curiosity and lets the class members draw out the implications. Give an EPS major a climate model and she’ll study for a day; teach her how to model the climate and she’ll advance the field herself.

The broadest life-lesson that Professor Boos wants students in his courses to understand is that in the midst of your undergraduate studies you cannot predict what issues or topic areas will grab you. But that’s the one, the topic that really makes you turn your head, which will enchant you enough to sustain you through the trials of academic study, and be the best chance you have to pursue your imagination while simultaneously earning a livelihood.  The bonus, the icing on the cake, will be when your work has a positive effect on people’s lives.

Back when he was a newly declared physics major, William Boos was walking by the Geology Department where the hallway was lined with displays of rocks. At the time he wondered how anyone could be interested in studying such things. It was a few years later during his Master’s program that he profoundly realized that there are connections between the local weather and the planetary climate, that short events held the keys to larger patterns. That was when he was hooked, and he has been happily studying those particular rocks ever since.
