In upwelling regions, wind relaxations lead to poleward propagating warm water plumes that are important to coastal ecosystems. The coastal ocean response to wind relaxation around Pt. Conception, CA is simulated with a Regional Ocean Model (ROMS) forced by realistic surface and lateral boundary conditions including tidal processes. The model reproduces well the statistics of observed subtidal water column temperature and velocity at both outer and inner‐shelf mooring locations throughout the study. A poleward‐propagating plume of Southern California Bight water that increases shelf water temperatures by ≈ 5°C is also reproduced. Modeled plume propagation speed, spatial scales, and flow structure are consistent with a theoretical scaling for coastal buoyant plumes with both surface‐trapped and slope‐controlled dynamics. Plume momentum balances are distinct between the offshore (>30 m depth) region where the plume is surface‐trapped, and onshore of the 30 m isobath (within 5 km from shore) where the plume water mass extends to the bottom and is slope controlled. In the onshore region, bottom stress is important in the alongshore momentum equation and generates vertical vorticity that is an order of magnitude larger than the vorticity in the plume core. Numerical experiments without tidal forcing show that modeled surface temperatures are biased 0.5°C high, potentially affecting plume propagation distance and persistence.

Purpose: Black Americans are dispropor­tionately affected by coronavirus disease 2019 (COVID-19) hospitalizations and deaths. Decreasing health disparities requires widespread uptake of COVID-19 testing, but attitudes about COVID-19 testing among Black Americans have not been studied. We aimed to characterize knowledge, attitudes, and beliefs about COVID-19 testing among Black parents.Methods: Semi-structured interviews were conducted and analyzed using a phenom­enology approach with 26 self-identified Black parents after telemedicine visits with a children’s health center. Interviews were recorded and transcribed; 65% were double coded with a resultant free-marginal inter­rater kappa score of 86.8%.Results: Most participants were women, spent time inside the homes of friends or family members, and almost half knew someone diagnosed with COVID-19. Three central themes emerged regarding COVID-19 testing decision making, includ­ing: 1) perceived COVID-19 disease suscep­tibility; 2) barriers to testing, with subthemes including trust in test accuracy and safety, perceived stigma of a positive test result, and impact of racism on self-efficacy; and 3) cues to action.Conclusions: When considering these themes as constructs of the Health Belief Model, we are better able to understand Black Americans’ views of COVID-19 test­ing and motivations for accessing testing. Culturally responsive educational campaigns delivered by trusted community members should aim to improve understanding about disease transmission and types of tests avail­able. Importantly, framing testing as a means to ensure safety may improve self-efficacy to obtain testing. Lastly, the health community should learn from these conversations with Black Americans so that disease prevention and mitigation strategies prioritize health equity.
