Cautionary tales from the mesoscale eddy transport tensor
نویسندگان
چکیده
The anisotropic mesoscale eddy transport tensor is diagnosed using passive tracers advected online in both an idealized 101-member mesoscale-resolving quasi-geostrophic (QG) double-gyre ensemble, and a realistic 24-member eddying (1/12∘) ensemble of the North Atlantic. We assert that Reynold’s decomposition along dimension, rather than spatial or temporal allows us to capture intrinsic spatiotemporal variability mean flow eddies. exhibits good performance reconstructing fluxes tracers, here defined as fluctuations about thickness-weighted averaged (TWA) mean. However, inability reconstruct QG potential vorticity, which encapsulates eddy-mean interaction, other active raises question: To what extent can be applied inform parametrization dynamics?

A boundary-value problem for the parameterized mesoscale eddy transport
We present a physically motivated boundary-value problem for each vertical ocean column, whose solution yields a parameterized mesoscale eddy-induced transport streamfunction. The new streamfunction is a nonlocal function of the properties of the fluid column. It is constructed to have a low baroclinic mode vertical structure and to smoothly transition through regions of weak stratification suc...
متن کاملThe perils of partialling: cautionary tales from aggression and psychopathy.
Although a powerful technique, the partialling of independent variables from one another in the context of multiple regression analysis poses certain perils. The present article argues that the most important and underappreciated peril is the difficulty in knowing what construct an independent variable represents once the variance shared with other independent variables is removed. The present ...
متن کاملThe clinical development of NRTIs — cautionary tales
The history of HIV is also the history of antiretroviral therapy (ART), the single most important measure in combating the HIV pandemic. The outcomes and in particular the interpretation of some early ART trials have greatly influenced the development of treatment guidelines and the course of ART implementation. A review of the development of NRTIs to date could be seen as a handbook of caution...

متن کاملFrom data to policy: good practices and cautionary tales.
Sound statistics are a key component of evidence. However, many institutional, political, and practical barriers impede effective use of data to inform policy. In the fourth paper in this Series on health statistics, we look at the relation between health statistics and policymaking at country and global levels. We propose a fourfold framework to help the transition from data to policy. Good pr...
