Investigation of the structure of natural orographic clouds embedded within atmospheric river type flow over the Payette Mountains in Idaho
The Seeded and Natural Orographic Wintertime clouds: the Idaho Experiment (SNOWIE) field campaign operated from January 7, 2017 – March 17, 2017, in the Payette Basin just northeast of Boise, ID. The goal of this campaign was to use radar and in-situ measurements to observe seeded and natural …

RELAMPAGO-CACTI drop size distribution observations and the implications for cloud and hydrologic studies
… light precipitation in vertically-pointing cloud radar data represent a unique characteristic of the Córdoba site relative to the other sites. As a result, the co-variability between DSD physical parameters indicates that the precipitation observed at Córdoba may confound existing drop size …

An Investigation Of Cloud Processes Relevant To Climate Sensitivity
… on the Fourth Assessment Report of the IPCC, cloud feedbacks are the largest source of uncertainty in predicting the Earth's climate response to CO2 radiative forcing. Various global climate models estimate that this response amplifies the initial CO2 forcing by a factor between 2 and 5. The …

Factors Governing Cloud Growth and Entrainment Rates in Shallow Cumulus and Cumulus Congestus During GoAmazon 2014/2015
Shallow cumulus and cumulus congestus clouds play an important role in the large-scale tropical circulation by mixing heat and moisture vertically and preconditioning the environment for deeper convection. Different representations of these shallow clouds also account for much of the spread in …

Dynamics of cloud-top generating cells in winter cyclones
Recent field observations suggest that cloud-top precipitation generating cells (GCs) are ubiquitous in the warm-frontal and comma-head regions of midlatitude winter cyclones. The presence of fall streaks emanating from the GCs, and their persistence either to the surface or until merging into …

Exploring methods to extract vertical motions in winter storms
… are tested for the 915 MHz profiler, a profiling radar on the University of Alabama-Huntsville Mobile Integrated Profiling System, used during several winter cyclones observed during the Profiling of Winter Storms (PLOWS) project. First, the profiler radial velocity measurements from two storms …

Analysis of vertical velocities and elevated instability in the comma-head of continental winter cyclones
… are investigated using the Wyoming W-band Cloud Radar mounted on the NSF/NCAR C-130, supplemented by analyses from the Rapid Update Cycle model and WSR-88D data. The cyclones followed three distinct archetypical tracks and were typical of those producing winter weather in the Midwestern …

Structure and statistical analysis of the microphysical properties of the comma-head region of cold-season midlatitude cyclones
… using data collected by the W-band Wyoming Cloud Radar and in-situ instrumentation aboard the NSF/NCAR C-130 research aircraft during the 2009-10 Profiling of Winter Storms (PLOWS) field campaign. The analyses describe the characteristics both of convective generating cells at cloud top, and …

A multi-sensor approach to the retrieval and model validation of global cloudiness
The ephemeral clouds have represented a daunting challenge to the atmospheric modeling community from the very beginning. Namely, their far-reaching importance to the energy balance and hydrological cycle of our planet is eclipsed only by the level of complexity at which they are nested within the …
