In a previous study, Chen and Snyder (2007) showed that a large location error in the background forecast can result in a poor performance of ensemble Kalman filter (EnKF) data assimilation (DA) due to the violation of the Gaussian assumptions.  One way to alleviate this issue is to apply vortex relocation (VR) before the ensemble-based DA.

Abstract: The maximum upward vertical velocity at the leading edge of a density current is commonly between 8-10 m/s. However, while the propagation speed and depth of a density current have been the subject of past studies, research describing the vertical velocity at the leading edge of a density current is relatively limited.

Abstract: The Shared Mobile Atmospheric Research and Teaching radars observed five landfalling tropical cyclones (TCs) from 2016-2018. The observations were largely targeted toward understanding asymmetric convective and dynamic processes. Such processes are thought to lead to the intensification of the TC primary tangential circulation, affect the distribution of extreme winds, and promote locally heavy rainfall. Relative to more traditional, aircraft-based analyses, the SMART radar datasets afford continuous high temporal and spatial resolution observations. These observations can be used to compliment and extend aircraft observed and numerically simulated TC processes.
