Are Increases in Thunderstorm Activity in Southeast China Related to Air Pollution?

Mar 12, 2015 Funded By: ARM ASR

Pollution aerosols are thought to have an invigorative effect on convective clouds by suppressing warm precipitation in moist and convectively unstable environments. As clouds develop to above the freezing level, mixed-phase clouds containing ice and supercooled water can grow further more readily and induce cloud electrification and thunderstorms during summertime. In southeastern China, the summer [...]

Strongly Absorbing Aerosols Affect Retrievals of Cloud Optical Depth

Mar 12, 2015 Funded By: ARM

Surface-based and satellite remote sensing techniques have proven indispensable for learning more about cloud temporal and spatial variations. Comparisons between cloud properties retrieved from surface and spaceborne platforms are commonly done as a way of validating satellite retrievals. Observations made at the surface are often treated as the “ground-truth” with respect to satellite retrievals. Both [...]

Filling Gaps Within Instrument Records

Mar 09, 2015 Funded By: ARM ASR

The ARM SGP site in Lamont, Oklahoma, is home to one of the longest records of actively sensed cloud information anywhere on the planet. Despite the best efforts of the program, instruments occasionally misbehave or are taken down for maintenance, resulting in holes within this record. Utilizing the Active Remote Sensing of Clouds Value-Added Product [...]

Quantifying the Importance of Cold Pool Mechanisms for Convection Triggering

Mar 09, 2015 Funded By: ASR

The organization of the subcloud layer into cold pools, areas of evaporatively cooled downdraft air spreading on the surface, is one of the key processes that help sustainin deep convection. It has long been known cold pools can spawn new convective cells by mechanically lifting air along their gust front. Such lifting could be the [...]

Modeling Precipitating Cumulus Congestus Observed by the ARM Radar Suite During the MC3E Field Campaign

Mar 04, 2015 Funded By: ARM ASR

Much of the uncertainty in climate model projections stems from the limited understanding of cloud and precipitation processes and the parameterization of these processes in global climate models (GCMs). Typically, results from cloud-resolving models (CRMs) or large-eddy simulation (LES) models serve as benchmarks for developing and tuning single-column models (SCMs), which, in turn, form the [...]
