Title of Contract, Award, or Gift: Wind-driven Rainfall Microphysics: Raindrop Shape - Fall Velocity - Size Distribution under Wind Shear and Turbulence

Name of Granting or Contracting Agency/Entity: Natl Science Fdn

Program Title: N/A
CFDA Linked: Engineering Grants


This proposed research will incorporate wind shear and turbulence into rainfall microphysics through (re-)evaluating their role in raindrop dynamics. This transformative approach and resulting predictive capabilities for microphysical quantities will improve the accuracy of radar rainfall retrievals. Therefore, results of this research will impact a wide spectrum of social-economical-political topics related to water availability, climate, and weather, impacting a large number of relevant applications such as better flood prediction, better management of water resources, and more accurate inputs for weather, climatological and hydrologic models. The HOD is the only available instrument (to the PI’s knowledge) that is capable of observing raindrop dynamics (e.g. collisions) that is needed to unravel the complex interference of wind and rainfall microphysics such as the one hypothesized herein. The HOD dataset that will be developed and shared with the scientific community will be unique and play an important role in accelerating the progress in rainfall microphysics research by providing quantities that could not have been measured/observed with the commercial technologies. The project will facilitate a workshop on raindrop-turbulence interactions. This topic is a frontier in this field, and the workshop will stimulate scientific discussions to address the relevant knowledge gaps. This project will leverage the research facilities that the PI has established at the University of Texas at San Antonio, a minority serving institution, to serve as both educational and research platforms for undergraduate and graduate students. The project will involve 2 doctoral students, approximately 15 undergraduate researchers, and reach over 400 undergraduate students (majority from underrepresented minority and female students) through outreach activities. The project will produce a number of peer-reviewed scientific publications.
