Who we are

Hello and welcome to the research group of Professor Sue van den Heever. Our research focuses on cloud processes, specifically the microphysical and dynamical characteristics of deep convective cloud systems, aerosol-cloud feedbacks, convective organization and the representation of these processes in numerical models. More detailed information on the scientific questions we are currently addressing can be found on our research webpage and from our publications. We utilize numerical models to achieve our scientific goals, in particular the open source Regional Atmospheric Modeling System (RAMS) that is developed and maintained by the van den Heever research group. We also draw on satellite and radar observations in our research, and numerous members of our research group have participated in a number of field campaigns. Our group, together with students from the Schumacher, Schubert, Rasmussen and Rutledge groups, recently completed C3LOUD-Ex, a field campaign to investigate updraft and cold pool characteristics of convective storms over NE Colorado. The field campaign utilized drones, radiosondes and radar data from the CSU-CHILL facility to address the campaign science goals and was recently described in the Colorado State University Magazine and on SOURCE. Several of our group also recently participated in NASA's CAMP2Ex held in the region of Philippines. More details about our CAMP2Ex activities were recently featured in SOURCE.

February 4: There's a new Dr. in the group! Congratulations to Peter Marinescu who successfully defended his PhD dissertation, "Observations of Aerosol Particles and Deep Convective Updrafts and the Modeling of Their Interactions." The new Dr. Marinescu will officially graduate in May.

January 30: Congratulations to Yasutaka, who successfully defended his MS Thesis, "On the Relation between Satellite Observed Liquid Water Path, Cloud Droplet Number Concentration and Cloud Base Rain Rate and Its Implication for the Auto-Conversion Rate in Stratocumulus Clouds." Yasutaka will stay on in pursuit of his PhD.

January 29: Congratulations to Minnie and Alex who have won First and Second place Student Oral Presentations respectively for their presentations at the 12th Symposium on Aerosol-Cloud-Climate Interactions during the American Meteorological Society annual meeting. Minnie's presentation, entitled "Understanding Aerosol Impacts on Tropical Land-Sea-Breeze Convection Using a Statistical Emulator Approach", was on tropical sea breezes, the focus of her PhD research. Aelx's presentation, titled Exploring the Sensitivity of Tropical Oceanic Convective Clouds to Aerosol Characteristics Under Differing Thermodynamic Environments, examined tropical congestus clouds in the context of the NASA CAMP2Ex field campaign.

January 21: Brianna Lund joins our group as a Research Associate. Brianna joins us from Radiometrics, where she worked in Quality and Customer Support. Welcome Brianna!

January 13-17: Alex, Leah, and Minnie present at the annual American Meteorological Society meeting in Boston.

December 9-13: Bowen, Emily, Sean, Steve, and Sue present at the annual American Geophysical Union meeting in San Francisco.

October 15: Edmore Kori, a PhD student from the University of Venda, begins visiting our group for a month. Edmore is studying geomorphology and the combined effects of rain and wind on soil. Welcome Edmore!

October 8: Alex, Sean, and Sue return from the NASA CAMP2Ex field campaign in the Philippines. They spent a combined 18 weeks in Clark Freeport Zone, Philippines to work on this important NASA field campaign in which 19 NASA P-3 flights were conducted. Our group oversaw dropsonde activities and made significant contributions to flight operations, flight planning and data analysis. The field campaign was a tremendous success, providing a suite of observations of the thermodynamic, microphysical, radiative and chemical characteristics of a variety of convective clouds from shallow cumulus to deeper congestus clouds, as well as the environment conditions in which they developed.
