Embry-Riddle Aeronautical University Convective–Boundary Research Engaging Educational Student Experiences 2.0 (ERAU C-BREESE 2.0) was a 15 day Doppler-on-Wheels (DOW) and Mobile Mesonet (MM) educational deployment in the summer of 2018 from the Center for Severe Weather Research (CSWR), funded by the National Science Foundation (NSF) through NCAR Lower Atmosphere Observing Facilities with a specific focus on Central Florida sub-regions that contain multiple mesoscale breezes and boundary collisions. The most scientifically interesting Intense Observing Period (IOP) was IOP 4, during which strong convection was observed over Cape Canaveral which then was followed by the development of a mid-tropospheric meso-low. The meso-low that was recorded on IOP 4 is believed to the first ever sampled meso-low by a CSWR DOW. Comparing DOW radar signatures to WSR-88D radar signatures allows us to better understand fine-scale features of the meso-low. Investigating the associated environmental characteristics and mechanisms associated provide us with a better understanding of what caused the formation and maintenance of the meso-low. To help determine formation and maintenance mechanisms NCEP HRRR and RAP analysis data were used to compare IOP 4 to other IOPs where no meso-lows were recorded.
