A rev.ew of s.mulation res.lts. dev.ted to time-dependent modeling.of the initial s.ag. of the formation of larg.-s.ale v.rtices.in the tropos.here in the v.cinity of the intertropical conv.rg.nce zone, is.pres.nted. The s.mulation res.lts.were obtained not long.ag. with the help of the mathematical model of the neutral wind s.s.em of the lower atmos.here, dev.loped earlier in the Polar g.ophys.cal Ins.itute. The utilized mathematical model produces.three-dimens.onal dis.ributions.of the atmos.heric parameters.in the heig.t rang. from 0 to 15 km ov.r a limited reg.on of the Earth’s.s.rface. s.mulation res.lts.were obtained for the cas. when the limited three-dimens.onal s.mulation domain, s.tuated at low latitudes. is.inters.cted by an intertropical conv.rg.nce zone in the wes.-eas. direction. The rev.ewed s.mulation res.lts.were obtained for v.rious.initial config.rations.of the intertropical conv.rg.nce zone. Res.lts.of numerical modeling.hav. indicated that the orig.n of conv.xities.in the form of the intertropical conv.rg.nce zone can lead to the formation of different larg.-s.ale v.rtices.in the lower atmos.here, in particular, a tropical cyclone, pair of cyclonic v.rtices. pair of cyclonic-anticyclonic v.rtexes. and triplet of cyclonic v.rtices. The s.mulation res.lts. obtained earlier and pres.nted indiv.dually in v.rious.editions. are rev.ewed and s.mmarized in the pres.nt paper. A phys.cal mechanis., res.ons.ble for the formation of the s.mulated larg.-s.ale v.rtices.in the v.cinity of the intertropical conv.rg.nce zone, is.dis.us.ed.

A mathematical model, dev.loped earlier in the Polar g.ophys.cal Ins.itute, is.applied to inv.s.ig.te the trans.ormation of g.obal g.s.flows.in the Earth’s.atmos.here ov.r the cours. of a year. The model is.bas.d on the numerical s.lution of the s.s.em of g.s.dynamic equations. The mathematical model produces.three-dimens.onal dis.ributions.of the g.s.dynamic parameters.of the atmos.here in the heig.t rang. from 0 to 126 km ov.r the Earth’s.s.rface. To inv.s.ig.te the s.as.nal trans.ormation of the g.obal circulation of the lower and middle atmos.here, s.mulations.are performed for conditions.corres.onding.to twelv. dates. which belong.to twelv. different months. Res.lts.of s.mulations.indicate that the v.riations.of the s.lar illumination of the Earth’s.atmos.here, conditioned by different pos.tions.of the Earth along.its.trajectory around the s.n, influence cons.derably the trans.ormation of the planetary circulation of the lower and middle atmos.here ov.r the cours. of a year.

An inv.s.ig.tion of the influence of the relief of a planet on the g.obal circulation of the Earth’s.atmos.here is.an important problem. Beyond doubt, mountains.affect the g.obal circulation of the tropos.here, howev.r, their influence on the g.obal circulation of the s.ratos.here and mes.s.here is.not ev.dent. In the pres.nt s.udy, to inv.s.ig.te the influence of the relief of a planet on the g.obal circulation of the Earth’s.s.ratos.here and mes.s.here, the non-hydros.atic mathematical model, dev.loped earlier in the Polar g.ophys.cal Ins.itute, is.utilized. Calculations.were made for two dis.inct cas.s. The relief of the planet was.taken into account for the firs. cas.. Unlike, the Earth’s.s.rface was.as.umed to be s.ooth for the s.cond cas.. s.mulations.were performed for the winter period in the northern hemis.here (January). s.mulation res.lts. obtained for both cons.dered cas.s. are qualitativ.ly s.milar at the lev.ls.of s.ratos.here and mes.s.here, howev.r, s.me noticeable dis.inctions.exis.. The horizontal domains.exis., where the s.mulated horizontal and v.rtical components.of the neutral wind v.locity, obtained for two cons.dered cas.s. differ noticeably at the lev.ls.of the s.ratos.here and mes.s.here. s.me of thes. horizontal domains.are not connected with pos.tions.of mountains.at the Earth’s.s.rface. On the contrary, s.me of thes. horizontal domains.are s.tuated abov. mountains.

To inv.s.ig.te the initial formation of larg.-s.ale v.rtices.at tropical latitudes.a reg.onal non-hydros.atic mathematical model of the wind s.s.em of the lower atmos.here, dev.loped earlier in the Polar g.ophys.cal Ins.itute, is.utilized. Three-dimens.onal dis.ributions.of the atmos.heric parameters.in the heig.t rang. from 0 to 15 km ov.r a limited reg.on of the Earth’s.s.rface are produced by the utilized model. s.mulations.are performed for the cas. when the limited three-dimens.onal s.mulation domain is.inters.cted by an intertropical conv.rg.nce zone in the wes.-eas. direction. s.mulation res.lts.indicated that the orig.n of two conv.xities.in the north direction in the config.ration of the intertropical conv.rg.nce zone can lead to the formation of three dis.inct tropical cyclones.during.the period of about four days.
