Multi-Point Mapping of Thunderstorm Electrical Structure

Instructions

Student presentations must have a faculty sponsor.

Abstracts must include a title and a description of the research, scholarship, or creative work. The description should be 150-225 words in length and constructed in a format or style appropriate for the presenter’s discipline.

The following points should be addressed within the selected format or style for the abstract:

A clear statement of the problem or question you pursued, or the scholarly goal or creative theme achieved in your work.
A brief comment about the significance or uniqueness of the work.
A clear description of the methods used to achieve the purpose or goals for the work.
A statement of the conclusions, results, outcomes, or recommendations, or if the work is still in progress, the results you expect to report at the event.

Presenter photographs should be head and shoulder shots comparable to passport photos.

Abstract

Knowledge of the electric field structures inside thunderstorms is necessary for understanding of thunderstorm electrification and resultant processes. However, existing knowledge comes largely from weather balloon measurements that provide a limited view that entangles motion of the balloon (spatial variability) with overall evolution of the storm (temporal variability). To disentangle spatial and temporal variability, a single balloon carrying multiple dropsondes can be released into a storm, where the dropsondes will be released one at a time, separated by a short time interval. In addition, a model to improve the analysis of the data can be built upon simple approximations of the electrification process, the resulting currents, charge structures, electric fields, and a crude probabilistic lightning model, and provides an electric field that can be used to study relativistic electron avalanche production. The models can then be compared to the recorded data to further interpret the information received.
