Journal ArticleDOI
Radiative impact of mineral dust on monsoon precipitation variability over West Africa
TL;DR: In this paper, the radiative forcing of dust and its impact on precipitation over the West Africa monsoon (WAM) region is simulated using a coupled meteorology and aerosol/chemistry model (WRF-Chem).
Journal ArticleDOI
More frequent intense and long-lived storms dominate the springtime trend in central US rainfall.
TL;DR: The observed increases in springtime total and extreme rainfall in the central United States are dominated by mesoscale convective systems (MCSs), the largest type of convective storm, with increased frequency and intensity of long-lasting MCSs.
Journal ArticleDOI
Mechanisms of convective cloud organization by cold pools over tropical warm ocean during the AMIE/DYNAMO field campaign
TL;DR: In this paper, the authors investigated the mechanisms of convective cloud organization by precipitation-driven cold pools over the warm tropical Indian Ocean during the 2011 Atmospheric Radiation Measurement (ARM) Madden-Julian Oscillation (MJO) Investigation Experiment / Dynamics of the AMIE/DYNAMO field campaign.
Journal ArticleDOI
Structure and Evolution of Mesoscale Convective Systems: Sensitivity to Cloud Microphysics in Convection-Permitting Simulations Over the United States
Zhe Feng,L. Ruby Leung,Robert A. Houze,Robert A. Houze,Samson Hagos,Joseph Hardin,Qing Yang,Bin Han,Jiwen Fan +8 more
TL;DR: In this article, the authors examined the uncertainties associated with cloud microphysics of convective storms in the central United States by using two different microphysical representations and comparing results with a warm-season satellite and radar observations.
Journal ArticleDOI
Dynamical and thermodynamical modulations on future changes of landfalling atmospheric rivers over western North America
TL;DR: This paper examined the changes of landfalling atmospheric rivers (ARs) over the west coast of North America in response to future warming using model outputs from the Coupled Model Intercomparison Project phase 5 (CMIP5).
