Lagrangian Coherent Structures and Vortex Formation in High Spatiotemporal‐Resolution Satellite Winds of an Atmospheric Kármán Vortex Street

Abstract: Recent advances in geostationary imaging have enabled the derivation of high spatiotemporal‐resolution cloud‐motion winds for the study of mesoscale unsteady flows. Due to the general absence of ground truth, the quality assessment of satellite winds is challenging. In the current limited practice, straightforward plausibility checks on the smoothness of the retrieved wind field or tests on aggregated trends such as the mean velocity components are applied for quality control. In this study, we demonstrate add… Show more

“…Specific examples include studies on zonal jets (Beron-Vera et al 2012), atmospheric rivers (Garaboa-Paz et al 2015, and the polar vortex (Serra et al 2017). Of particular relevance to the ABL are the studies identifying LCS in laboratory boundary layers using two-dimensional Particle Image Velocimetry (Green et al 2007;Pan et al 2009;Wilson et al 2013;He et al 2016;Eisma et al 2021), predicting downdraft and significant shear events in near-surface doppler lidar measurements at the Hong Kong International Airport (Tang et al 2011;Knutson et al 2015), studying atmospheric Karman Vortex street from satellite wind measurements (Günther et al 2021), and understanding aerosol dispersion patterns in the stratosphere (Aksamit et al 2021).…”

“…Afterwards, Horváth et al (2020) and Günther et al (2021) used a time series of Geostationary Operational Environmental Satellite-R (GOES-R) winds to investigate the evolution of the AVKVS in the lee of Guadalupe Island on 9 May 2018. These latest observational studies highlighted an asymmetry in the vorticity decay of cyclonic and anticyclonic vortices, which was attributed to the effect of Earth's rotation and the nonaxisymmetric shape of the island.…”
