CW3E Summer Interns

Class of 2021

Hillary Beckmeyer

Mentors: Allison Cobb, Forest Cannon, and Tom Corringham

Project Title/Topic: Attributing Commercial Shipping Losses to Extreme Weather in the North Pacific

Hillary is originally from Okemos, MI, although for the last 6 years she has called Boulder, CO, home. She is a recent graduate from the University of Colorado Boulder where she studied Atmospheric and Oceanic Sciences. She previously had also obtained a degree in International Relations and Comparative Cultures & Politics from Michigan State University’s James Madison College. Her interests include traveling, hiking, and studying air-sea interactions and climate change. This summer, before her internship with CW3E, Hillary was involved in a research project examining how oceanic barrier layers are represented in the latest generation of global climate models, and how such models predict barrier layers will respond to global climate change.

Lauren Bolotin

Mentors: Nina Oakley and Luke Odell

Project Title/Topic: Investigating Relationships Between Extreme Hourly and Sub-Hourly Precipitation in California

Project Summary

Lauren graduated with a B.S. in Ecohydrology and Environmental Science from the University of Nevada Reno in 2019. This summer, Lauren worked with and learned from Nina Oakley and Luke Odell at CW3E to investigate the relationship between 15-minute and hourly precipitation observations, particularly during extreme precipitation as it relates to the risk of post-fire debris flows. Despite the fact that sub-hourly precipitation observations are scarce in comparison to hourly observations, these data are crucial for monitoring debris flow risk across California, especially as wildfire activity increases in the state. Lauren is excited to continue her time in San Diego earning her M.S. in Watershed Science at San Diego State University

Brandon Bourassa

Mentors: Jennifer Haase

Project Title/Topic: Improved Atmospheric River Forecasting using Airborne Radio Occultation

Brandon is a rising senior at UCSD, pursuing a degree in Oceanic and Atmospheric Science. . This summer Brandon had the opportunity to work with Jennifer Haase and her team, to investigate a real-time data-retrieval method using Airborne Radio Occultation (ARO) to retrieve refractivity profiles. By comparing these refractivity profiles, Brandon was able to determine if a real-time method can be used in place of a post-processed one. This real-time method has the potential to greatly improve the accuracy of forecast models. This coming year Brandon plans to apply to graduate programs and pursue on-campus research.

There have been many people that have helped Gilberto get to where he is today and he hopes one day to pay it forward as he obtains his PhD. He is already doing so by his involvement with the Stockton Community where he grew up. Through the help of the Community Involvement Program he has been not only been able to give back to the community but inspire the youth of the community to pursue a higher education. At the end of the day Gilberto wants to help out as much as he can and explore the world with the bright mindset he has been able to create for himself.

Madison graduated from Colorado Mountain College in 2019 with a B.A. in Sustainability Studies. While attending CMC, she also competed as a Division 1 alpine ski racing athlete and conducted an internship at a local environmental non-profit. Madison’s sustainability background has enabled her to apply systems thinking to sustainability challenges and motivates her to educate, engage, and inspire people to build a more sustainable future. Madison’s research project focused on measuring streamflow variability in the Upper Yampa River Basin, in Colorado. This involved working with local stakeholders to understand how they are planning and thinking about variability. The project was very field-based, taking streamflow measurements at key locations in the watershed. Madison’s mentors were Anna Wilson, Michael Sierks, Michelle Stewart, and Nathan Stewart. Without a doubt, Madison will be skiing a lot this upcoming year! Also, continuing work as a program director at the Yampa Valley Sustainability Council (YVSC) and assisting in the development of a water and snow program at YVSC.

Hamish Prince

Mentors: Peter Gibson and Mike DeFlorio

Project Title/Topic: Extreme Atmospheric River Events Under Climate Change

Hamish is a recently graduated MSc student from New Zealand (University of Otago) where he was examining atmospheric river (AR) seasonality and impacts in the Southern Hemisphere. He undertook a CW3E summer internship working with Peter Gibson and Mike DeFlorio exploring the genesis location of the most costly atmospheric rivers to make landfall on the west coast of the USA in collaboration with Tom Corringham, Alison Cobb, and Bin Guan. This work utilized the most recent advances in AR life-cycle tracking algorithms to identify the genesis location of all ARs that make landfall on the west coast of the USA. These AR lifecycles were paired with calculated financial damages recorded during these events to identify if there are any factors at the point of genesis which indicates the potential damage of an approaching AR. Hamish had plans to start graduate school in the USA in Fall 2020, but these plans have been deferred due to travel restrictions and he will be staying in New Zealand continuing on with personal research.
