60°S-62°S Witnessed a Shift Pattern of Southern Ocean Boundary Layer Aerosols and CCN
Niu, Qing (2021)The Southern Ocean (SO), dominated by high surface wind speeds associated with frequent cyclones, is the most pristine environment on Earth, providing a natural laboratory to study the correlation of marine boundary layer ... -
An Analysis of the Microphysical and Thermodynamic Properties of Elevated Convective Cells within Snowbands Associated with Winter Storms.
Hall, Christian (2023-12-15)In-situ and remote sensing observations of snowbands were obtained by probes on a cloudpenetrating NASA P-3 and a high-altitude NASA ER-2 aircraft, to identify and characterize elevated convective cells (CCs). Observations ... -
Assessing Precipitation Delineation Capabilities of Spaceborne Radars
Searls, Maresa (2022-08-04)Spaceborne radars uniquely measure, provide the finest depiction of, and give the most accurate estimate of precipitation globally from space. The Global Precipitation Measurement (GPM) mission dual-frequency precipitation ... -
Characteristics of Tropopause Polar Vortices Based on Observations Over The Greenland Ice Sheet
Borg, Sarah (2018-12-14)Tropopause Polar Vortices (TPVs) are long-lived, coherent vortices that are identified by closed material contours of potential temperature on the dynamic tropopause. They are characterized by PV anomalies that spend most ... -
Design and Implementation of a Novel Multicopter Unmanned Aircraft System for Quantitative Studies of the Atmosphere
Segales Espinosa, Antonio Ricardo (2022-12-16)The call for creating new innovative meteorological instruments to help fulfill observational gaps in the atmospheric sciences has been gaining strength in the past few years. This comes along with the urgent need to ... -
Ice Crystal Size Distributions in Tropical Mesoscale Convective Systems in the Vicinity of Darwin, Australia: Results from the HAIC/HIWC Campaign
Brechner, Peter (2021-12)Total ice water content (IWC) derived from an isokinetic evaporator probe and ice crystal size distributions measured by a two-dimensional stereo probe and precipitation imaging probe installed on the French Falcon aircraft ... -
Impact of Microphysics Parameterization Schemes on the Assimilation of GOES-16 All-Sky Infrared Radiances for a Bow Echo Analysis and Prediction
Kim, Yu-Shin (2023-08-04)Assimilating infrared brightness temperature (BT) from the water vapor sensitive channels of the GOES-16 Advanced Baseline Imager (ABI) has been shown by past studies to improve the analysis and prediction of severe weather ... -
In situ and satellite-based estimates of aerosol-cloud interactions between biomass burning aerosols and marine stratocumulus clouds over the southeast Atlantic Ocean
Gupta, Siddhant (2021-12)Ubiquitous low-level, marine stratocumulus clouds provide the largest contribution of all cloud types to the shortwave cloud radiative forcing. A cooling effect from small changes in low-level cloud properties due to ... -
In Situ Observations of Southern Ocean Clouds from The SOCRATES Field Campaign: Evaluating Cloud Phase, Aerosol-Cloud Interactions, Cloud Layer Types and Entrainment-Mixing Impacts on Mixed Phase Clouds
D'Alessandro, John (2022-12-16)Low level clouds are ubiquitous over the Southern Ocean. However, climate and weather models fail to accurately simulate their radiative impact. This has been attributed in part to the inadequate representation of cloud ... -
Influences of the Aerosol Invigoration Effect on Radar Signatures of Deep Convection near Houston TX Using a Bulk Statistical Framework
Pehl, Jonah (2023-08-04)Aerosol-deep convective cloud (DCC) interactions remain a frontier in the study of water cycles, energy budgets, climate models, and air quality, partly because it can be difficult to disentangle aerosol impacts from the ... -
Information content analysis of combined lidar-polarimeter retrievals to improve aerosol remote sensing accuracy
Nowicki, David (2021)Aerosols are small particles suspended in the atmosphere which affect global climate change via scattering and absorbing sunlight and serving as cloud condensation nuclei. Moreover, the prevalence of some anthropogenic and ... -
A Microphysical Analysis of the Stratiform Rain Region of Mesoscale Convective Systems using Polarimetric Radar and In Situ Aircraft Measurements
Murphy, Amanda (2018-12-14)The benefits of using polarimetric weather radar data to infer microphysical properties of and processes within observed precipitation is becoming more widely recognized. The quasi-vertical profile (QVP) technique has ... -
Modeling CCN Effects on Electrification within High and Low Precipitation Supercells
Blair, Jessica (2021-08)Cloud condensation nuclei (CCN) are known to affect both the electrical and the dynamic evolution of storms, but the effects on storm electrification in different storm modes have not been thoroughly examined. We will ... -
Satellite and Radar Remote Sensing of Tropical Cyclones to Quantify Microphysical and Precipitation Processes
Brauer, Noah (2022-08-04)Precipitation microphysics in tropical cyclones (TCs) are often poorly represented in numerical simulations, which ultimately affects TC structure, evolution, and prediction. This provides a large incentive to better observe ... -
