MuSpain kusanaya kwemvura kunoitika zvakajairika uye zvakasarudzika munzvimbo dzese dzeMediterranean. Kuwanda uye kusimba kwavo inowedzerwa nemhedzisiro yekuchinja kwemamiriro ekunze Uye, kunyangwe zviitwa zvehupfumi nemaitiro echisikigo akachinjika nehunhu hwemamiriro ekunze, havakwanise kuzviita mune ino mamiriro, ayo anokanganisa kugadzikana.
Aya mamiriro ekusanaya uye kukwira kwetembiricha kwaendesa kune kunodziya uye kunopisa zvikuru mumazana matatu emakore apfuura mumakumi emakore apfuura. Ndezvipi zvinokanganisa mamiriro aya?
Kuwedzera kupisa, kushoma mvura
Kwemakumi maviri emakore, nhengo dzeboka rekutsvaga Mamiriro ekunze, Mvura, Shanduko yeGlobal uye Natural Systems dzeDhipatimendi reGeography uye Spatial Planning ivo vanogadzira zvakare mamiriro ekunze ekare kubva mukukura kwakakura kwemiti yechinyakare muSpain. Nekutsvagisa uku ivo vanoda kuziva kuti mamiriro ekunze anga anga akaita sei mumazana emakore apfuura uye nekugona kufungidzira kuomarara uye kufambira mberi kwemhedzisiro yeshanduko yemamiriro ekunze.
Tinofanira kuyeuka kuti shanduko zhinji dzemamiriro ekunze dzakaitika munhoroondo yese, asi hadzina kukurumidza seidzo dziri kuitika nhasi. Nekuwedzera kwetembiricha tembiricha yakafanana nezviripo nhasi, mamirioni emakore akapfuura. Nekudaro, ikozvino shanduko yemamiriro ekunze iri kuitika pamwero wevanhu, ndiko kuti, mumazana mashoma emakore.
Ruzivo urwu rwunogona kuwanikwa kuburikidza nekudzidza kwekuwedzera kwemhepo yemiti yakadai semapaini. Iyo Geophysical Tsamba Tsamba tsamba ikozvino inounganidza kuongororwa kwe masampula kubva pamiti mazana manomwe nemakumi mana neshanu yemarudzi Pinus sylvestris naPinus uncinata iri munzvimbo yemakomo eIberian, sezvo kureba kwezvinyorwa zvemamiriro ekunze (dhata yakayerwa muzviteshi zvemamiriro ekunze) inosvika pamakore zana, nguva isina kukwana yekuyera kusarudzika kwemamiriro ekunze aripo.
Kudzidza kwekukura kwemuti
Kutenda kune ruzivo rwakatorwa kubva pazviyero zvekukura kwemiti, zvinokwanisika kuziva kuti mamiriro ekunze akashanduka sei. Kana muti wega wega ukasimudza huni dzekupedzisira, ndiko kuti, iyo yakasviba inogadzirwa mumatanho ekupedzisira ekukura kwegore, zvinokwanisika kuvaka zvakare mhedzisiro yekusanaya mumazhizha kubvira makumi emakore ekutanga ezana ramakore gumi nemasere.
Basa rakatanga nemazhizha ezana ramakore gumi nemasere kubva zvaive kutanga kweshanduko yemabhizimusi umo magasi ekupfumisa akatanga kuburitswa kuburikidza neindasitiri.
Ino inguva yekutanga kuti vesaenzi vakwanise kuvakazve mamiriro ekunze emakore apfuura nenzira iyi. Unyanzvi hunodaidzwa Yakagadziriswa Evaporation uye Transpiration Index (SPEI), yakataurwa mune iyi kesi kumwedzi waJuly naAugust. Zhizha dzave kuwedzera kuoma kudzamara, nhasi, ndidzo dzinoisa marekodhi enhoroondo.
Chinhu chinorangarirwa mune izvi zviyero uye chakakosha kugadzirira mhedzisiro uye mhedzisiro ndechekuti indekisi iyi inoshandiswa muzviyero inoteedzera kuwedzera kwekushushikana kunowanikwa nehurongwa hwezvisikwa kana paine kuderera kusingawanzoitika kwemvura , mune mamiriro umo, nekuda kwekudziya kwepasi, tembiricha yegore negore iri kuwedzera mberi.
Mhedzisiro yakawanikwa yakaoneswa nevamwe vanyori kubva kuEurope neNorth Africa, avo vanonongedzera mukusarudzika kwekusanaya kwakanyanya kwakaitika mukupera kwezana ramakore rechimakumi maviri uye neizvo zvinoitika izvozvi mumakore apfuura.
Shanduko mumaitiro emuchadenga nekuda kwekuchinja kwemamiriro ekunze chiito pamwero mukuru uye vanokwanisa chinja chinzvimbo nekutsungirira kweAnticyclone muAzores izvo hazvibvumidze madutu kupinda muSpain uye, nekudaro, mvura. Uye zvakare, kudzokorodza kukuru kwezviitiko zvakaoma kwakaenderana nezvakabuda mushumo uchangoburwa weIntergovernmental Panel pamusoro pekushanduka kwemamiriro ekunze.
