Abstract: An observational analysis of the Northern Hemisphere circulation during winter reveals that the leading mode of variability depends on longitude. In particular, the first EOF of the zonal-mean circulation differs over the ...

Abstract: In this short note, the effect of enhanced circulation due to doubling CO2 on ozone is investigated. The difference of Brewer?Dobson circulation (BDC) between the doubled CO2 and control run from an idealized atmospheric ...
