A 16-Year Observational Analysis of Land-Atmosphere Coupling in Oklahoma Using Mesonet and North American Regional Reanalysis Data
(2018-08)
Global “hot spots” for land atmosphere coupling have been identified through various studies. One particular region that has been identified in many of these global studies is the Southern Great Plains (SGP) of North ...
A Microphysical Analysis of the Stratiform Rain Region of Mesoscale Convective Systems using Polarimetric Radar and In Situ Aircraft Measurements
(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 ...
Correcting, Improving, and Verifying Automated Guidance in a New Warning Paradigm
(2018-05-11)
The prototype Probabilistic Hazards Information (PHI) system allows forecasters to experimentally issue dynamically evolving severe weather warning and advisory products in a testbed environment, providing hypothetical end ...
ATMOSPHERIC VARIATIONS IN COLUMN INTEGRATED CO2 ON SYNOPTIC AND SEASONAL TIME SCALE OVER THE U.S.
(2018)
Past studies have demonstrated that synoptic events play an important role in the spatial and temporal variations of carbon dioxide (CO2). In this study, in order to investigate whether cold fronts have impact on synoptic ...
Strengths and Limitations of NSSL's Experimental Warn-on-Forecast System for Ensembles in Forecasting Cyclic Mesocyclogenesis
(2018-12-14)
Cyclic mesocyclogenesis is the process by which a supercell produces multiple
mesocyclones with similar life cycles. Supercells that exhibit cyclic mesocyclogenesis
(i.e. cyclic supercells) have the potential to produce ...
Evaluation of the Madden-Julian Oscillation and the Stratospheric Polar Vortex and Their Joint Influence on the Northern Hemisphere Extratropical Circulation
(2018-12)
Multiple modes of climate variability inform long-range Northern Hemisphere (NH) winter weather prediction through their interactions with the atmosphere. Two specific modes of variability that are the focus of this study ...
ANALYSIS OF FLOW AND THERMODYNAMIC CHARACTERISTICS AT A SITE IN COMPLEX TERRAIN
(2018-08)
The goal of the Perdigão Field Experiment was to study atmospheric flows in complex terrain and to collect a high-quality dataset for the validation of meso- and micro-scale models. An Intensive Observation Period (IOP) ...
Observing system simulation experiment studies on the use of small UAV for boundary-layer sampling
(2018)
A long-desired component to the U.S. operational observing systems is the capability to measure vertical profiles of wind, temperature and moisture in the lower troposphere at high spatial and temporal resolution. This ...
Kinematics, Thermodynamics, and Microphysics of the 25-26 June 2015 Kansas MCS during PECAN
(2018-05)
This case study analyzes a nocturnal mesoscale convective system (MCS) that was observed in northeast Kansas as part of the Plains Elevated Convection at Night (PECAN) field experiment on 25-26 June 2015. Over the course ...
South Pacific Atmospheric Internal Variability and Its Role in El Niño-Southern Oscillation
(2018)
Accurate long-range seasonal prediction of the El Niño-Southern Oscillation (ENSO) phenomenon is of critical importance to predict regional and global climate anomalies. The overarching goal of this work is to seek the ...
