Synoptic Modulation of the West African Coastal Atmosphere and Mesoscale Convective Systems

Naoko Sakaeda, Shun-Nan Wu, Rosimar Rios‐Berrios, Elinor R. Martin et autres

Abstract This study uses high-resolution airborne data from the NASA Convective Process Experiments–Cabo Verde field campaign to examine the effects of synoptic conditions on mesoscale convective systems (MCSs) over the western coastal waters of West Africa. African easterly waves (AEWs) are the …

In-cloud characteristics observed in northeastern and midwestern US non-orographic winter storms with implications for ice particle mass growth and residence time

Luke R. Allen, Sandra E. Yuter, Declan M. Crowe, Matthew A. Miller et autres

The spatial distribution of surface snowfall accumulation is dependent on the 3D trajectories of ice particles and their residence times through regions of ice mass increases and decreases. We analyze 42 non-orographic, non-lake-effect winter storms in the northeastern and midwestern United States …

Supercooled Liquid Water at the Top of a Snow‐Producing Nimbostratus Cloud and Its Association With Gravity Wave Breaking and Turbulence: An IMPACTS Case Study

Mei Juan Han, Scott A. Braun, Timothy James Lang, Matthew L. Walker McLinden et autres

Abstract Supercooled liquid water (SLW) at the top of a snow‐producing nimbostratus cloud was thoroughly characterized with remote‐sensing and in situ measurements during the NASA Investigation of Microphysics and Precipitation for Atlantic Coast‐Threatening Snowstorms (IMPACTS) field campaign on 30 January 2022. With …

Look Within: Intraplume Differences on Smoke Aerosol Aging Driven by Concentration Gradients

Nicole A. June, Elizabeth Brooke Wiggins, Edward L. Winstead, Claire E Robinson et autres

Abstract The evolution of organic aerosol (OA) composition and aerosol size distributions within smoke plumes are uncertain due to variability in the rates of OA evaporation/condensation and coagulation within a plume. It remains unclear how the evolution varies across different parts of …

On the Prediction of Aerosol‐Cloud Interactions Within a Data‐Driven Framework

Xiangyu Li, Hailong Wang, TC Chakraborty, Armin Sorooshian et autres

Abstract Aerosol‐cloud interactions (ACI) pose the largest uncertainty for climate projection. Among many challenges of understanding ACI, the question of whether ACI can be deterministically predicted has not been explicitly answered. Here we attempt to answer this question by predicting cloud droplet …
