A variational optimization analysis approach to continuous data assimilation /
(The University of Oklahoma., 1975)
Computational aspects of the adjoint method.
(1997)
Modern numerical weather prediction often employs an adjoint of the forecast model to optimally initialize the model with observations of the state of the atmosphere and thus to improve the accuracy of the forecast. This ...
Prediction of cloud-to-ground lightning in the western United States.
(2002)
This dissertation focuses specifically on identifying the thermodynamic environment and forcing mechanisms across the western United States that create precipitation systems with lightning. The majority of these convective ...
Dynamic adjustment in an idealized numerically-simulated bow echo.
(2002)
While the large-scale atmosphere is governed by relatively simple dynamic balance relations that describe the mutual adjustment between the mass and wind fields (e.g., hydrostatic and geostrophic balances), no simple ...
Variational pseudo multiple-Doppler analyses of a dryline utilizing very-high resolution mobile Doppler radar data.
(2004)
The dryline has long been associated with the development of severe thunderstorms in the southern Plains during the spring and early summer months. The propagation and structure of the dryline are closely tied to surface ...
Application of the Forward Sensitivity Method to Data Assimilation of the Lagrangian Tracer Dynamics
(2014-05)
The analysis of the dynamics of a tracer/drifter/buoy floating on the free surface of the water waves in the open ocean whose motion is described by the shallow water model equations is of great interest in Lagrangian data ...
Phase-correcting data assimilation and application to storm-scale weather prediction.
(1999)
New observing systems such as the Oklahoma Mesonet, the NEXRAD Doppler radar network, and high resolution satellite data present the opportunity to make accurate numerical weather predictions on the mesoscale and thunderstorm ...
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 ...
