Longitude‐latitude distribution of WN1 in monthly‐mean geopotential at 10 hPa level in (a) November 2018 and (b) June 2011, which are classified as WQBO and EQBO, respectively, as derived from monthly‐averaged Aura/MLS data.

Quasi‐stationary planetary Rossby waves forced in the extratropical troposphere propagate upwards into the stratospheric vortex and can also be refracted toward the equator. To the extent that such waves penetrate the low latitudes they will be observable as quasi‐stationary zonal eddies in the equatorial middle stratosphere. These eddies should be...

Plain Language Summary
The Brewer‐Dobson circulation, responsible for mass, heat and constituents global transport in the stratosphere, is projected to accelerate in a warming climate. This circulation is driven by the momentum transferred by dissipating waves. We explore the seasonality of trends in wave dissipation in the subtropical lower strato...
Midlatitude atmospheric variability is dominated by the dynamics of the baroclinically unstable jet stream, which meanders and sheds eddies at the scale of the Rossby deformation radius. The eddies interact with each other and with the jet, affecting the variability on a wide range of scales, but the mechanisms of planetary‐scale fluctuations of th...
Climate trends and weather indicators are used in several research fields due to their importance in statistical modeling, frequently used as covariates. Usually, climate indicators are available as grid files with different spatial and time resolutions. The availability of a time series of climate indicators compatible with administrative boundari...
O acesso à cidade é uma condição que indica a capacidade de uma população se apropriar de atividades urbanas. Distintas localidades possuem diferentes distânciaspara atividades de interesse social, sendo este um dos fatores de desigualdade. Compreender os níveis de acesso em uma cidade possibilita planejar medidas estratégicaspara as necessidades d...
We investigate the characteristics of equatorial waves associated with the maintenance of superrotation in the stratosphere of a Titan general circulation model. A variety of equatorial waves are present in the model atmosphere, including equatorial Kelvin waves, equatorial Rossby waves, and mixed Rossby-gravity waves. In the upper stratosphere, ac...
