Assessment of stratospheric wave activity associated with the Madden-Julian Oscillation (MJO) and its potential impact on the Quasi-Biennial Oscillation (QBO)
(2021-12)
The Madden-Julian Oscillation (MJO) and Quasi-Biennial Oscillation (QBO) are known to provide sub-seasonal to seasonal predictability, yet their dynamics and interactions are not fully understood. Many recent studies have ...
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 ...
Rapid-scan, polarimetric, mobile, Doppler-radar observations of the formation, evolution, and structure of the El Reno tornado of 31 May 2013
(2016-10)
On 31 May 2013, the mobile, Rapid-scan, X-band, Polarimetric (RaXPol) radar collected a high spatial and temporal resolution dataset documenting the genesis, intensification, and dissipation of a tornado that caused EF-3 ...
The Impact of the Madden-Julian Oscillation on Extreme Winter Weather in the United States
(2022-08)
Winter weather has substantial impacts on human activity, but it is challenging to predict more than 7-10 days in advance. Subseasonal-to-seasonal (S2S) prediction is a rapidly developing field of meteorology that could ...
Large Scale and Local Influences on the Occurrence and Maintenance of Liquid Bearing Clouds over the Greenland Ice Sheet
(2016)
Arctic liquid bearing clouds (LBCs) have a large impact on the surface radiation and cryospheric mass budgets. Their effect on the surface radiation budget is a combination of two competing processes. First, they can ...
Evaluation of the Warn-on-Forecast System with Doppler Lidar and Mobile Radiosondes from TORUS2019
(2020)
Doppler lidar and mobile radiosonde observations from the Targeted Observations with
Radars and UAS of Supercells 2019 (TORUS2019) eld project are compared to the environ-
mental guidance NSSL Warn-on-Forecast System ...
Boundary Layer Profiling Using Rotary-Wing Unmanned Aircraft Systems: Filling the Atmospheric Data Gap
(2018-08)
The planetary boundary layer (PBL) is comprised of energy exchanges with the Earth’s surface, and as such plays a large factor in the evolution of weather con- ditions. However, traditional methods of observing the atmosphere, ...
Structure of tropopause polar vortices represented from the atmospheric profiles of satellite observations
(2022-12-16)
Tropopause polar vortices (TPVs) are sub-synoptic tropopause disturbances commonly found poleward of the polar jet stream. Their roles in cyclogenesis and linkages to mid-latitude weather make them relevant to the improvement ...
Verification of the Tornado and Lightning Plumes and Evaluation of a New Kernel for the Tornado and Lightning Plumes
(2020-07-30)
Though tornado forecasts have been of interest much longer, the National Weather Service (NWS) has been issuing tornado alerts and warnings for more than 50 years. On 1 October 2007, the NWS began issuing storm-based ...
Understanding the Features and Mechanisms of the Great Plains Low-Level Jet in CMIP5 Models
(2016-12)
The Great Plains low-level jet (GPLLJ) is an important driver of precipitation and severe weather outbreaks over the U.S. Great Plains during the spring and summer. Therefore, it is extremely important that features of the ...
