Mphepo yamkuntho ku Atlantic

kuchuluka kwa mphepo mu Atlantic

Chifukwa cha kusintha kwa nyengo komanso kuwonjezeka kwa kutentha kwapakati pa dziko lonse lapansi tili ndi kusintha kosiyana mumlengalenga ndi nyanja. Pamenepa, nyanja ya Atlantic ikuchenjeza za kusintha komwe kukuchitika chifukwa cha kusintha kwa nyengo. The mvula yamkuntho ku Atlantic iwo akuchulukirachulukira ndipo ndi iwo kupanga mphepo yamkuntho ndi mphepo yamkuntho mphamvu.

M'nkhaniyi tikuuzani zomwe zachititsa kuti mphepo zamkuntho ziwonjezeke ku nyanja ya Atlantic komanso zotsatira za kusintha kwa nyengo m'nyanja ya Atlantic yomwe ikukula kwambiri.

Mphepo yamkuntho ku Atlantic

mphepo yamkuntho mu Atlantic

Nyanja ya Atlantic ichenjeza. Ichi ndi chidule cha kusintha kwa kayendedwe ka mlengalenga komwe kunachitika m'zaka zaposachedwapa zomwe zimakhudza kumpoto kwa Macaronesia, dera lomwe limaphatikizapo Azores, Canary Islands, Madeira ndi zilumba za m'chipululu, ndi kum'mwera chakumadzulo kwa Iberia Peninsula. Chilichonse chikusonyeza kuti derali likusintha nyengo yotentha.

Chiyambireni mbiri yakale mu 2005 ya mvula yamkuntho Delta kupita kuzilumba za Canary, kuchuluka kwa mphepo zamkuntho zomwe zimadutsa maderawa. chawonjezeka kwambiri m’zaka 15 zapitazi. Mphepo zamkunthozi ndi madera omwe nyengo yake imakhala yotsika kwambiri ndipo sawonetsa mkuntho wamkuntho wapakati pa latitude kapena mphepo zamkuntho zomwe tidazolowera kudera lino ladziko lapansi. M'malo mwake, amawonetsa mawonekedwe ofanana kwambiri ndi mphepo yamkuntho yomwe nthawi zambiri imakhudza nyanja ya Caribbean kutsidya lina la Atlantic.

M'malo mwake, zochitikazi zikufanana kwambiri ndi mvula yamkuntho m'mapangidwe ndi chilengedwe. Mochuluka kwambiri kuti US National Hurricane Center yawonjezera kafukufuku ndi kuyang'anira madzi athu m'zaka zaposachedwa, ndipo adatchula gulu losawerengeka la zochitikazi.

Kuwonjezeka kwa mphepo yamkuntho ku Atlantic

cyclone ku South Atlantic

Zosokoneza zomwe tazitchula pamwambapa zawonjezeka m'zaka zisanu zapitazi. Tili ndi zitsanzo zodziwika bwino:

  • Mphepo yamkuntho Alex (2016) Zinachitika kumwera kwa Azores, pafupifupi makilomita 1.000 kuchokera ku Canary Islands. Ndi mphepo yamkuntho yopitilira makilomita 140 pa ola limodzi, imafika pamtunda wa mphepo yamkuntho ndikuyenda modabwitsa kudutsa kumpoto kwa Atlantic. Inakhala mphepo yamkuntho yoyamba kupanga mu Januwale kuyambira 1938.
  • Mphepo yamkuntho Ophelia (2017), mkuntho woyamba wa Saffir-Simpson Gulu 3 kum'mawa kwa Atlantic kuyambira pomwe zolemba zidayamba (1851). Ophelia adapeza mphepo yopitilira ma kilomita 170 pa ola limodzi.
  • Mphepo yamkuntho Leslie (2018), mphepo yamkuntho yoyamba kufika pafupi kwambiri ndi gombe la peninsula (makilomita 100). Inagunda ku Portugal mbandakucha ndi mphepo yothamanga mpaka makilomita 190 pa ola.
  • Mphepo yamkuntho Pablo (2019), mphepo yamkuntho yapafupi kwambiri yomwe sinayambikepo ku Ulaya.
  • Monga mafunde ake omaliza, Tropical Storm Theta idawopseza zilumba za Canary, makilomita 300 okha kuchokera ku zilumbazi.

Kuphatikiza pa milanduyi, pali mndandanda wautali womwe umatsagana nawo popeza ndi wodabwitsa kwambiri ndipo umakhudza madera omwe tawatchulawa. Mwanjira imeneyi, kuchuluka kwachulukira kufika kamodzi pachaka m'zaka zisanu zapitazi, komanso kangapo pazaka ziwiri zapitazi. Chaka cha 2005 chisanafike, ma frequency anali amodzi zaka zitatu kapena zinayi zilizonse, osayimira chiwopsezo chachikulu cha kukhudzidwa.

Anomalies mu nyengo ya 2020

mvula yamkuntho

Kusowa kumeneku n’kogwirizana ndi zimene zimachitika m’nyengo yamkuntho kuyambira June mpaka November chaka chino. Zolosera kale zikunena za nyengo yotanganidwa kwambiri yomwe idzafike pachimake mvula yamkuntho 30, mbiri yowona. Izi zikutanthauza kuwatchula mayina pogwiritsa ntchito zilembo zachi Greek, kupitilira nyengo ya 2005.

Kumbali inayi, nyengoyi imadziwikanso ndi mphepo zamkuntho zazikulu za Gulu 3 kapena kupitilira apo. M'malo mwake, imalumikizana ndi nyengo zinayi zoyambirira kwa nthawi yoyamba kuyambira pomwe zolemba zidayamba (1851) kuti osachepera Gulu limodzi 5 mphepo yamkuntho yapanga mu nyengo zisanu zotsatizana. Zotsirizirazi zimagwirizana kwambiri ndi zochitika za kusintha kwa nyengo, mphepo yamkuntho yamphamvu kwambiri imakhala yamphamvu kwambiri komanso yowonjezereka.

Maphunziro a kusintha kwa nyengo

Tiyenera kukumbukira kuti kuwonjezereka kwa mphepo zamkuntho ku Atlantic ndi kutentha kwa gawo lino la dziko lapansi kumagwirizana ndi zotsatira za kusintha kwa nyengo. Yankho ndi inde, koma kufufuza kwina kuli kofunika.. Kumbali imodzi, tiyenera kudziwa ubale ndi zomwe zawonedwa, ndipo ku Spain tilibe luso lochita maphunziro amtunduwu omwe amachitika m'maiko ena. Zomwe tingakhazikitse ndi ubale wozikidwa pa kafukufuku wazowonetsa zanyengo zamtsogolo zomwe zimaganiza kuti izi zimachitika pafupipafupi m'mabeseni athu.

Apa ndipamene tingamangire maubwenzi, ngakhale kuti kafukufuku wochuluka akufunika kuti adziwe ndi kukonzanso zenizeni za zochitika zam'tsogolozi kuti athe kukonza mapulani kuti agwirizane ndi kusintha kwa nyengo komwe kukuyembekezeka. Ngakhale zili zoona kuti ndizotheka osafika pamphamvu kwambiri monga gulu 3 kapena kupitilira apoMphepo yamkuntho ndi mvula yamkuntho yaing'ono yotentha imakhalanso yodetsa nkhaŵa kwambiri chifukwa cha kukhudzidwa kwake kwakukulu pamphepete mwa nyanja ya US ndipo ziyenera kuwonjezeredwa kuti ku Spain sitinakonzekere mokwanira izi.

Khalidwe lina loyenera kulingaliridwa ndikuti amawonetsa kusatsimikizika kwakukulu pakulosera kwawo. Mosiyana ndi madera otentha, kumene njira zamphepo zamkuntho zimakhudzidwa ndi zinthu zodziwikiratu, pamene mphepo zamkunthozi zimayamba kufika kumadera athu apakati, zimayamba kutengera zinthu zomwe sizingadziwike, ndikuwonjezera kusatsimikizika. Mbali ina yofunika ndi kuthekera kwamphamvu kwambiri akayamba kusinthika kukhala mikuntho yapakati pa latitude, kusintha komwe kumadziwika kuti extratropical transition, komwe kumatha kuwapangitsa kuti awonjezere kuchuluka kwawo.

Pomaliza, ndikofunikira kuti tiganizirenso za kusatsimikizika komwe kungachitike muzochitika zomwe zikuchitika muzochitika zomwe tikukambazo. Ngakhale kusintha konseku kumaganiziridwa nthawi zonse ponena za mbiri yakale kuyambira 1851, kuyambira 1966 kuti zolemba izi. zitha kuganiziridwa ngati zolimba komanso zofananirana ndi zomwe zamasiku athu ano, chifukwa ndicho chiyambi cha zotheka. Yang'anani ndi ma satelayiti. Chifukwa chake, izi ziyenera kukumbukiridwa nthawi zonse popenda zomwe zimachitika mkuntho ndi mvula yamkuntho.

Ndikukhulupirira kuti ndi chidziwitsochi mungaphunzire zambiri za zomwe zimayambitsa kuwonjezeka kwa mphepo yamkuntho ku Atlantic.


Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
