The Fingerprint of Evapotranspiration: Quantifying Moisture Source Impacts on Hydroclimate Variability and Drought Risk

January 22, 2026

Yan Jiang

Hosted by Dien Wu

Precipitation regimes over global croplands are sustained by complex moisture transport pathways from land and ocean. Since oceanic and terrestrial evaporation regulate rainfall patterns and seasonality in distinct ways, disturbances in these sources can expose downwind croplands to different hydrological risks. Beyond traditional climate and hydrological modeling, a key question for food…

A Unified Scaling Framework for Drop Size Distributions: Single or Double Moments?

January 15, 2026

GyuWon Lee

Hosted by Michael Bell and Kristen Rasmussen

Drop size distributions (DSDs) are fundamental to advancing our understanding of precipitation microphysics and improving quantitative precipitation estimation and forecasting. Since Marshall and Palmer (1948) parameterized DSDs using a single-parameter exponential function, their explicit representation has become a key component of both remote sensing retrievals and numerical weather…
