Zvirokwazvo makanzwa zviuru zvenguva panhau pamusoro pe Azores anticyclone. Icho chiitiko chemeteorological chinokanganisa mamiriro ekunze eIberian Peninsula uye iyo inofanirwa kunzwisiswa zvakanyanya kuti tinzwisise zvikonzero nemhedzisiro yainayo pamamiriro ekunze eSpanish. Masayendisiti akadzidza iyi anticyclone kwemakore akawanda uye ine kukosha kukuru mukufanotaura kwemamiriro ekunze.
Nechikonzero ichi, isu tichakumikidza chinyorwa ichi kukuudza kuti chii chinonzi Azores anticyclone, maitiro ayo, zvikonzero uye mhedzisiro.
Chii chinonzi anticyclone
Chinhu chekutanga kuziva kuti anticyclone chii. An anticyclone inzvimbo yekumanikidza kwakanyanya (pamusoro pe1013 Pa) umo kudzvanywa kwemuchadenga kwakakwira kupfuura kudzvanywa kwemhepo kwakatenderedza uye kunowedzera kubva kunharaunda yakananga pakati. Inogona kazhinji kuve yakabatana nemamiriro ekunze akagadzikana, denga rakajeka, uye kupenya kwezuva.
Iyo anticyclone ikholamu inogadzikana kupfuura mweya wakakomberedza. Nekudaro, mweya unodonha pasi unogadzira chiitiko chinonzi kunyura, zvinoreva kuti chinotadzisa kuumbwa kwemvura. Ehe, inofanirwa kutariswa kuti nzira iyo mweya unodzika nayo inosiyana zvichienderana nehemisphere mairi.
Aya anticyclonic airflows ari nyore kukudziridza muzhizha, zvichiwedzera kuwedzera mwaka wekuoma. Kusiyana nemadutu, ayo zviri nyore kufanotaura, kazhinji vane chimiro uye maitiro asina kujairika. Mukutaura, anticyclones inogona kukamurwa kuita mapoka mana kana mapoka.
Chii chinonzi Azores anticyclone
Pakutanga kuona, kuve meteorologist muAzores kungaita sechinhu chiri nyore, asi zvese zvinopenya haisi goridhe. Maanticyclone anozivikanwa usashandure nguva dzose kumamiriro ekunze akagadzikana pamusoro pezvitsuwa. Munyika yedu inowanzotivimbisa mamiriro okunze akaoma uye ezuva muzhizha, asi zvinoitikawo munzvimbo dzedu dzechando. Inoitawo izvi nekudzikamisa mhepo uye nekukonzera yakakurumbira kusvibiswa kwechando zvikamu mumaguta makuru. Naizvozvo, ndiro rine basa rekumaka nguva mulatitude yedu. Asi yakaumbwa sei?
Maumbirwo ayo anoenderana nekutenderera kwemuchadenga uye musiyano wetembiricha pakati peequator nemapango. Kupisa kwezuva kunoturikira mukupisa kwakanyanya munzvimbo dzeequatorial, izvo zvinoita kuti mweya unodziya ukwire nekuda kwekudzikira kwayo. Mhepo inodziya inokwira kwete muhupamhi chete, asiwo mulatitude.
Kusvikira ku30°-40°N. Pano, inodzika kuburikidza nekunyura kunoguma nekugara uye zero updraft, kugadzira anticyclone. Saka izvi zvinoturikira kumamiriro ekunze akadzikama uye ane zuva.
Muchirimo, inowanzosvika kuWestern Europe, ichivharira kupinda kwemadutu kubva kuchamhembe kwelatitude. Munguva yechando, kune rumwe rutivi, isu tiri kure kure nayo nokuti subsidence inoitika mberi kumaodzanyemba. Kupinza kwedutu nemhepo inotonhora inobva yasununguka kufamba-famba munzvimbo dzakaderera. Mamiriro ekunze muIberian Peninsula achakanganiswa nekusundidzira uye kudhonza kweaanticyclone nemadutu kubva kuchamhembe.
Mamiriro ekunze akaita sei neAzores anticyclone?
Kunyangwe zvitsuwa izvi zvakapihwa zita reiyo anticyclone ine mukurumbira, mamiriro ekunze pachitsuwa ane kubatikana kupfuura zvataifunga pakutanga. Saizvozvo, mamiriro okunze anochinja zvikuru uye ane mwando. Ehe, kana ukaronga kuenda zhizha rino, usaite uchifunga nezvezuva uye nzvimbo dzemahombekombe. Panzvimbo pezvo, funga nezvezvitsuwa izvi sechisarudzo chokunzvenga kupisa. Iwe uchawana tembiricha ine mwero, asi iwe unotozoshamisika zvechokwadi kana ikanaya rimwe zuva.
Zvichienderana nezvitsuwa zvatinoshanyira, mamiriro okunze achasiyana, kunyange zvazvo kuine mwero zvikuru pasina mwaka wokusanaya kwemvura uye chirimo chiri pakati nepakati. Muzvitsuwa zvepakati nekumabvazuva, mamiriro ekunze ari pakati nepakati, ane mwaka wakaoma uye munyoro wezhizha.
Nekuda kweizvozvo, mwaka wezhizha unopfava kupfuura mwaka wechando, uye mvura zhinji inonaya pakati paGumiguru naKurume. Muchidimbu, pane musiyano muduku pakati pemwaka mumwe nomumwe. Izvo zvichagara zviripo zvichave nekunyorova kwakawanda. Chimiro chemamiriro ekunze chakabatana nerubatsiro rwemugungwa chinopa zvitsuwa kusvibira uye chikamu cherunako rwenzvimbo inouratidza.
Musiyano nemadutu
Zvakajairika kuvhiringa anticyclone nemadutu, sezvo madutu anonziwo madutu. Zvisinei, ivo vakapesana. Kuti tinzwisise musiyano mukuru pakati pezviitiko zviviri zvemamiriro ekunze, ngatinzwisise kuti tsananguro yedutu chii.
Madutu imhepo inopararira zvishoma uye inokwira. Inzvimbo iyo mhepo yemhepo yakaderera pane yakapoteredza. Kuenda kumusoro kwemhepo kunofarira kuumbwa kwemakore, nokudaro kugadzirwa kwekunaya kwemvura. Mhepo dzinokonzerwa nemhepo inotonhora, uye nguva yadzo inoenderana nehuwandu hwemhepo inotonhora yadzinotakura. Aya marudzi emhepo yakawanda haana kugadzikana, anoumba uye anofamba nokukurumidza.
Kuchamhembe kwehemisphere, dutu rinotenderera richitarisa wachi. Aya mamhepo emhepo anounza nemamiriro ekunze asina kugadzikana, ane makore, anonaya kana kuti ane dutu, uye dzimwe nguva sinou munguva yechando.
Azores anticyclone uye shanduko yemamiriro ekunze
Ongororo dzekudziya kwepasirese dzinoratidza kuti iyo Azores anticyclone inogona kunge yakawedzera mumakore achangopfuura, yakasununguka kubva kune yakajairwa ENSO-mhando oscillations, zvichitungamira kune yakanyanya kunaya zviitiko kumaodzanyemba kwakadziva kumabvazuva kweUnited States. Panogona zvakare kuve nekuchinja kwelatitudinal kwecrest, paine mamwe mamodhiyo emakombuta anomiririra kumwe kumadokero kwekuwedzera kweramangwana anticyclone. Zvisinei, munguva yechando ye2009-2010, iyo anticyclone yakava diki, yakatamira kuchamhembe kwakadziva kumabvazuva, uye yakanga isina simba kupfuura nguva dzose, iyo yakakonzera kukurumidza kuwedzera kwekushisa kwepamusoro pakati peAtlantic.
Sezvauri kuona, iyo Azores anticyclone yakakosha kumamiriro ekunze epeninsula uye inobatsira zvikuru kufanotaura mamiriro ekunze. Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezveAzores anticyclone uye maitiro ayo.
