Particle trajectories are computed both along an isobaric (500 hPa) and an isentropic (315 K) surface in a time interval of one year. Besides mean quantities such as advection of the center of mass and growth of tracer clouds, special attention is paid to the evaluation of particle pair separation dynamics. The characteristic behavior for intermediate time scales is Batchelor's dispersion along both surfaces, where the zonal extent of the tracer cloud increases linearly in time. The long-time evolution after 70\u201380 days exhibits a slower, diffusive dispersion (Taylor regime), in agreement with expectations. Richardson\u2013Obukhov scaling (superdiffusion with an exponent of 3\/2) could not be identified in the numerical tests. The results confirm the classical prediction by Batchelor that the initial pair-separation determines subsequent time evolution of tracers. The quantitative dependence on the initial distance differs however from the prediction of the theory. <\/jats:p>","DOI":"10.1142\/s0218127412502410","type":"journal-article","created":{"date-parts":[[2012,11,8]],"date-time":"2012-11-08T08:56:12Z","timestamp":1352364972000},"page":"1250241","source":"Crossref","is-referenced-by-count":2,"title":["ADVECTION OF PASSIVE TRACERS IN THE ATMOSPHERE: BATCHELOR SCALING"],"prefix":"10.1142","volume":"22","author":[{"given":"T\u00cdMEA","family":"HASZPRA","sequence":"first","affiliation":[{"name":"Department of Theoretical Physics, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P\u00c9TER","family":"KISS","sequence":"additional","affiliation":[{"name":"Department of Physics of Complex Systems, E\u00f6tv\u00f6s Lor\u00e1nd University, P\u00e1zm\u00e1ny P\u00e9ter s\u00e9t\u00e1ny 1\/A, Budapest, H-1117, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"TAM\u00c1S","family":"T\u00c9L","sequence":"additional","affiliation":[{"name":"Department of Theoretical Physics, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"IMRE M.","family":"J\u00c1NOSI","sequence":"additional","affiliation":[{"name":"Department of Physics of Complex Systems, E\u00f6tv\u00f6s Lor\u00e1nd University, P\u00e1zm\u00e1ny P\u00e9ter s\u00e9t\u00e1ny 1\/A, Budapest, H-1117, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2012,11,8]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1002\/qj.49707632804"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1121726"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1175\/1520-0469(1981)038<2264:RDOCLB>2.0.CO;2"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1175\/JAS4006.1"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1016\/j.ocemod.2008.01.006"},{"key":"rf6","volume-title":"Ocean Circulation: Wind-Driven and Thermohaline Processes","author":"Huang R.
