Our simulations show that the Asian monsoon anticyclone is highly variable in location and shape and oscillates between 2 states: first a symmetric anticyclone and second, an asymmetric anticyclone either elongated or split in two smaller anticyclones. A maximum in the distribution of air originating from Indian/Chinese boundary layer sources is usually found in the core of the symmetric anticyclone, in contrast the asymmetric state is characterised by a double peak structure in the horizontal distribution of air originating from India and China. The simulated horizontal distribution of artificial emission tracers for India/China is in agreement with patterns found in satellite measurements of O3 and CO by the Aura Microwave Limb Sounder (MLS). The contribution of different boundary source regions to the Asian monsoon anticyclone strongly depends on its intraseasonal variability and is therefore more complex than hitherto believed, but in general the highest contributions are from North India and Southeast Asia at 380 K. In the early (June to mid-July) and late (mid-August to October) period of the monsoon 2012, contributions of emissions from Southeast Asia are highest and in the intervening period (≈ mid-July to mid-August) emissions from North India have the largest impact. Further, our simulations confirm that the thermal tropopause above the anticyclone constitutes a vertical transport barrier. Enhanced contributions of emission tracers for Asia are found at the northern flank of the Asian monsoon anticyclone between double tropopauses indicating an isentropic transport from the anticyclone into the lowermost stratosphere. 000256583 536__ $$0G:(DE-HGF)POF3-244$$a244 - Composition and dynamics of the upper troposphere and middle atmosphere (POF3-244)$$cPOF3-244$$fPOF III$$x0 000256583 588__ $$aDataset connected to CrossRef 000256583 7001_ $$0P:(DE-Juel1)129123$$aGünther, G.$$b1$$ufzj 000256583 7001_ $$0P:(DE-Juel1)129138$$aMüller, Rolf$$b2$$ufzj 000256583 7001_ $$0P:(DE-Juel1)129122$$aGrooss, Jens-Uwe$$b3$$ufzj 000256583 7001_ $$0P:(DE-Juel1)129145$$aRiese, M.$$b4$$ufzj 000256583 773__ $$0PERI:(DE-600)2069857-4$$a10.5194/acpd-15-9941-2015$$gVol. 15, no. 7, p. 9941 - 9995$$n7$$p9941 - 9995$$tAtmospheric chemistry and physics / Discussions$$v15$$x1680-7375$$y2015 000256583 8564_ $$uhttps://juser.fz-juelich.de/record/256583/files/acpd-15-9941-2015.pdf$$yOpenAccess 000256583 8564_ $$uhttps://juser.fz-juelich.de/record/256583/files/acpd-15-9941-2015.gif?subformat=icon$$xicon$$yOpenAccess 000256583 8564_ $$uhttps://juser.fz-juelich.de/record/256583/files/acpd-15-9941-2015.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000256583 8564_ $$uhttps://juser.fz-juelich.de/record/256583/files/acpd-15-9941-2015.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000256583 8564_ $$uhttps://juser.fz-juelich.de/record/256583/files/acpd-15-9941-2015.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000256583 8564_ $$uhttps://juser.fz-juelich.de/record/256583/files/acpd-15-9941-2015.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000256583 8767_ $$92015-07-01$$d2015-07-01$$eAPC$$jZahlung erfolgt$$pacp-2015-103 000256583 909CO $$ooai:juser.fz-juelich.de:256583$$pdnbdelivery$$popenCost$$pVDB$$pdriver$$pOpenAPC$$popen_access$$popenaire 000256583 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000256583 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000256583 915__ $$0LIC:(DE-HGF)CCBY3$$2HGFVOC$$aCreative Commons Attribution CC BY 3.0 000256583 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ 000256583 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000256583 9141_ $$y2015 000256583 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129164$$aForschungszentrum Jülich GmbH$$b0$$kFZJ 000256583 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129123$$aForschungszentrum Jülich GmbH$$b1$$kFZJ 000256583 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129138$$aForschungszentrum Jülich GmbH$$b2$$kFZJ 000256583 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129122$$aForschungszentrum Jülich GmbH$$b3$$kFZJ 000256583 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129145$$aForschungszentrum Jülich GmbH$$b4$$kFZJ 000256583 9131_ $$0G:(DE-HGF)POF3-244$$1G:(DE-HGF)POF3-240$$2G:(DE-HGF)POF3-200$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bErde und Umwelt$$lAtmosphäre und Klima$$vComposition and dynamics of the upper troposphere and middle atmosphere$$x0 000256583 9201_ $$0I:(DE-Juel1)IEK-7-20101013$$kIEK-7$$lStratosphäre$$x0 000256583 9801_ $$aUNRESTRICTED 000256583 9801_ $$aFullTexts 000256583 980__ $$ajournal 000256583 980__ $$aVDB 000256583 980__ $$aUNRESTRICTED 000256583 980__ $$aI:(DE-Juel1)IEK-7-20101013 000256583 980__ $$aAPC 000256583 981__ $$aI:(DE-Juel1)ICE-4-20101013
