The formation and life cycle of microburst phenomena using mathematical modeling
Andrew L. Straessle, United States Naval Academy, Annapolis, MD
The causes behind the formation and the life cycle of the microburst phenomena are not completely understood. Through this work, I hope to create a model of the structure and cycle of microbursts as they carry out their short life spans. I also hope that by taking on this challenge, a better understanding of the atmospheric conditions that lead to their occurrence will be gained.
Microburst systems create strong wind shears with outflow winds producing damage up to F3 intensity and are a large contributor to aviation accidents every year. Constant advances have been made over the years to receive more up-to-date information regarding microbursts using techniques such as Doppler radar. There are two classes of microburst events, dry or wet, depending upon whether heavy precipitation accompanies the system. Current models are capable of reflecting atmospheric conditions surrounding dry microburst systems but fail when applied to wet microbursts. Continuous research is being done to find a model that works for all microburst systems and the atmospheric conditions associated with them.
This project will encompass two semesters. The first semester will be used to gain an understanding of the mathematical computation that will need to be taken into account for in the model as well as research on conditions surrounding microburst activity. Second semester will be used to develop the model and attempt to find a pattern within the previously studied atmospheric conditions that favors the formation of microburst systems. The mathematical graphics program Mathematica will be used for this project to develop the proposed model of microburst systems.
