Sensitivity of the mid‐winter Arctic stratosphere to QBO width in a simplified chemistry–climate model
Abstract This study is the first to assess the sensitivity of the mid‐winter Arctic stratosphere to variability in the width of the quasi‐biennial oscillation (QBO).

| Summary: | Abstract This study is the first to assess the sensitivity of the mid‐winter Arctic stratosphere to variability in the width of the quasi‐biennial oscillation (QBO). Differences between a pair of idealised simulations with a simplified chemistry–climate model are examined. The width of the QBO appears to have equal influence on the Arctic stratosphere as does the phase (i.e. the Holton‐Tan mechanism). In the model, a wider QBO acts like a preferential shift towards the easterly phase of the QBO. That is, on average, a wider QBO is associated with a weaker Arctic vortex and with enhanced total ozone at high latitudes. Copyright © 2011 Royal Meteorological Society |
