Zinthu Zokhudza Kuwongolera Mphepo: Ndemanga Yokwanira
Mphepo ndi kayendedwe ka mpweya kopingasa kuchokera kumadera omwe ali ndi mphamvu zambiri kupita kumadera omwe ali ndi mphamvu zochepa. Chochitikachi ndi zotsatira za zinthu zosiyanasiyana zomwe zimagwira ntchito mogwirizana mumlengalenga wa Dziko Lapansi. Kumvetsetsa zinthu zomwe zimakhudza njira ya mphepo ndikofunikira osati pa nyengo ndi nyengo zokha komanso pa ntchito zosiyanasiyana monga kuyendetsa ndege, kuyenda panyanja, ndi mphamvu zongowonjezedwanso. Nkhaniyi ikambirana zina mwa zinthu zazikulu zomwe zimatsimikiza njira ya mphepo mumlengalenga wa Dziko Lapansi : kusiyana kwa mphamvu ya mpweya, mphamvu ya Coriolis, kukangana kwa pamwamba, malo, ndi kutentha.
1. Kusiyana kwa Kupanikizika kwa Mpweya
Mphepo kwenikweni imayenda kuchokera kumadera omwe ali ndi mphamvu zambiri kupita kumadera omwe ali ndi mphamvu zochepa pofuna kulinganiza kusiyana kwa mphamvu mumlengalenga. Kusiyana kwa mphamvu kumeneku nthawi zambiri kumachitika chifukwa cha kutentha kosafanana kwa pamwamba pa Dziko Lapansi ndi dzuwa. Pamene nthaka kapena madzi akutenthedwa, mpweya pamwamba pawo umakula ndikukhala wochepa, kukwera, zomwe zimapangitsa kuti pakhale mphamvu zochepa. Mosiyana ndi zimenezi, m'madera omwe amalandira kutentha pang'ono, mpweya umakhalabe wozizira komanso wokhuthala, zomwe zimapangitsa kuti pakhale mphamvu zambiri.
Liwiro la mphepo ndi komwe ikupita zimatsimikiziridwa ndi ma gradient a kupanikizika, kusiyana kwa kupanikizika pakati pa mfundo ziwiri zosiyana. Ma gradient amphamvu a kupanikizika amapanga mphepo yamphamvu komanso yachangu. Mawonekedwe a isobars (mizere pamapu yomwe ikuwonetsa kupanikizika kofanana) angapereke chithunzi chomveka bwino cha dera lomwe mphepo idzayenda komanso momwe ingakhalire yamphamvu.
2. Zotsatira za Coriolis
Kuwonjezera pa kusiyana kwa mphamvu, kuzungulira kwa Dziko Lapansi kumakhudzanso njira ya mphepo kudzera mu zomwe zimadziwika kuti Coriolis effect. Chifukwa cha kuzungulira kwa Dziko Lapansi, mphepo zomwe zimayenda kuchokera kumadera omwe ali ndi mphamvu zambiri kupita kumadera omwe ali ndi mphamvu zochepa zimapatutsidwa kuchoka panjira yawo yowongoka. Kumpoto kwa Dziko Lapansi, mphepo zimapatutsidwa kupita kumanja, pomwe Kum'mwera kwa Dziko Lapansi, zimapatutsidwa kupita kumanzere. Mphamvu ya Coriolis iyi imaonekera kwambiri pa mphepo zazikulu, monga mphepo zamalonda ndi mitsinje ya ndege, kuposa mphepo zakomweko.
Mwachitsanzo, mphepo zomwe zimayenda kuchokera kudera lotentha lokhala ndi mphamvu yamphamvu kupita kudera lokhala ndi mphamvu yamphamvu ya equator ku Northern Hemisphere zidzatembenuzidwa kupita kumanja, zomwe zimapangitsa mphepo zamalonda zakumpoto chakum'mawa. Izi zikufotokoza chifukwa chake machitidwe a nyengo m'madera apakati ndi apamwamba nthawi zambiri amazungulira m'njira ya cyclonic kapena anticyclonic , kuzungulira mozungulira wotchi kapena motsutsana ndi wotchi, kutengera gawo lomwe lili.
3. Kukangana kwa pamwamba
Kukangana pakati pa mphepo ndi pamwamba pa dziko lapansi kumakhudza momwe mphepo imayendera komanso liwiro lake, makamaka mphepo yomwe imayandikira pamwamba pa nthaka (nthawi zambiri imaonedwa ngati kutalika kwa pafupifupi kilomita imodzi). Kukangana kumeneku kumachepetsa liwiro la mphepo ndipo kumasintha momwe mphepo imayendera kuchokera ku zomwe zingakhale "zosasokonezeka" Coriolis ngati mphepo ikanakhala mumlengalenga wapamwamba. Chinthu ichi ndi chofunikira kwambiri m'madera omwe ali ndi mitundu yosiyanasiyana ya pamwamba monga mizinda, nkhalango, ndi mapiri.
Kukangana kumapangitsa kuti mphepo pafupi ndi pamwamba ziyende mwachindunji kumadera omwe ali ndi mphamvu yochepa kuposa mlengalenga wapamwamba. Izi zikutanthauza kuti, poganizira za Coriolis effect, mphepo pamwamba sizimangobwerera m'mbuyo komanso zimayandikira mizere ya mphamvu.
4. Malo omwe ali
Malo okhala ndi mpweya nawonso amagwira ntchito yofunika kwambiri podziwa komwe mphepo ikupita . Mphepo ikakumana ndi chotchinga monga phiri, phiri, kapena chigwa, iyenera kusintha njira yake. Mapiri amatha kuyambitsa mphepo kukwera ndipo amathanso kupanga zotsatira za mphepo ya katabatic ndi anabatic. Mphepo ya Katabatic ndi mphepo yomwe imatsika kuchokera kumapiri kupita kumadera otsika , nthawi zambiri usiku pamene mpweya pamwamba pake umakhala wozizira kwambiri komanso wokhuthala. Mphepo ya Anabatic ndi yosiyana, pomwe mphepo imakwera m'mapiri masana pamene mapiri akutentha ndipo mpweya womwe uli pamwamba pake umakula ndikukwera mmwamba.
Kujambula malo kungapangitsenso zotsatira monga mphepo ya fohn kapena föhn, komwe mpweya wodutsa pamwamba pa phiri umafunda ndi kuuma pamene ukutsika mbali inayo, zomwe zimapangitsa kuti m'derali mukhale kutentha komanso kouma.
Malo a m'nyanja ndi m'mphepete mwa nyanja nawonso amakhudza momwe mphepo imayendera. M'madera a m'mphepete mwa nyanja, mphepo za m'nyanja ndi mphepo za pamtunda nthawi zambiri zimachitika chifukwa cha kusiyana kwa kutentha pakati pa nthaka ndi nyanja. Masana, nthaka yofunda imapanga malo otsika omwe amakoka mphepo kuchokera ku nyanja yozizira (mphepo ya m'nyanja). Usiku, zosiyana zimachitika (mphepo ya pamtunda).
5. Kutentha
Kusiyana kwa kutentha ndi chinthu chachikulu chomwe chimakhudza momwe mphepo imayendera. Mitundu yosiyanasiyana ya kutentha padziko lonse imatanthauzira madera osiyanasiyana a nyengo ndi momwe mphepo imayendera mwachindunji padziko lonse lapansi. Madera otentha a equator amachititsa kuti mpweya ukwere, zomwe zimapangitsa kuti pakhale madera otsika mphamvu, pomwe madera ozizira kwambiri a polar amapanga madera amphamvu mphamvu. Mphepo zapadziko lonse monga mphepo zamalonda, madera akumadzulo, ndi madera akumadzulo ndi zotsatira za kusiyana kwa kutentha kwapadziko lonse.
Kumbali yakumaloko, kusiyana kwa kutentha pakati pa usana ndi usiku, chilimwe ndi nyengo yozizira, komanso kusiyana kwa kutentha pakati pa zinthu zosiyanasiyana monga nthaka ndi madzi, zonsezi zimakhudza momwe mphepo imayendera komanso liwiro lake.
Mapeto
Kumvetsetsa komwe mphepo ikupita komanso zinthu zomwe zimakhudza mphepo sikuti ndikofunikira kokha pakuphunzira za nyengo komanso kungakhale ndi zotsatirapo zofunika kwambiri. Kusiyana kwa kuthamanga kwa mpweya, mphamvu ya Coriolis, kukangana kwa pamwamba, malo, ndi kutentha zonse zimagwirizana m'njira zovuta kudziwa momwe mphepo idzayendera komanso komwe idzayende. Kuyembekezera komwe mphepo ikupita kumathandiza pa kulosera bwino nyengo, kukonza bwino kayendetsedwe ka ndege ndi kayendetsedwe ka nyanja, komanso kupanga bwino magwero amphamvu obwezerezedwanso monga mphepo. Kudziwa ndikumvetsetsa zinthuzi kudzapitirira kukhala gawo lofunikira kwambiri m'magawo osiyanasiyana asayansi ndi ntchito zaukadaulo.
