Due to the COVID-19 Pandemic, the University has instruction to cancel all in-person events through the Spring semester to adhere to city and state orders limiting public gatherings. Events still running must now take place Online— listed events will include a link in which one may access the Online webspace:

To view Mr. Selke’s defense, enter his Online chatroom via Blackboard Collaborate— it will open at 11:30 am (one hour prior to the event start time) on Thursday, April 23, 2020.

Modeling of Cloud Droplet Formation: Software Development and Sampling Strategies

Mr. Niklas Selke
University of Wisconsin-Milwaukee
MS Graduate Student – Research Assistant

“Updraft speeds are an important factor in the formation of cloud droplets which play an important role in an atmospheric simulation. The updraft speeds are varying very strongly in small areas of space. To account for that kind of variability on a coarse numeric grid, used for simulations, the updraft speed will be modeled by drawing samples from an underlying probability density function that is describing the updraft speeds. We will start by discussing the current implementation of the droplet formation process to then describe the necessary changes that allow us to use sampled values for the updraft speed. After that we will look at different sampling strategies to determine how well the process is converging for each of these strategies.”
