Simudza ruoko rwako kana wanzwa izwi rekuti "king tide." Simudza ruoko rwako kana izwi richikutumira kumhanyisa kune tidal charts kune yako chikamu chemahombekombe. Simudza ruoko rwako kana zvichireva kuti uchachinja mafambiro ako emazuva ese kuti usabuda munzvimbo dzine mafashamo nekuti nhasi kuchange kuine “king tide”.

King tide haisi izwi repamutemo resainzi. Iri izwi rinowanzoshandiswa kutsanangura kunyanya mafungu emvura-seaya anoitika kana paine kurongeka nezuva nemwedzi. Mafungu emambo haasi iwo iwo chiratidzo chekuchinja kwemamiriro ekunze, asi, seAustralian Green Cross webhusaiti "Pupurira Mambo Tides” inoti, “Vanotipa chiono chakajeka chekuti kukwirira kwemakungwa kungaite sei. Kureba chaiko kunosvikwa nemafungu amambo kuchaenderana nemamiriro ekunze enzvimbo uye mamiriro egungwa pazuva racho.”

Mumakumi emakore adarika, kunyanya mafungu emvura ainyanya kuda kuziva—zvinenge zvisinganzwisisike kana akanganisa maitirwo ehupenyu munzvimbo dzine mafungu. Munyika yose mumakore gumi apfuura, mafungu emadzimambo ari kuwedzera kubatanidzwa nemigwagwa ine mafashamo uye mabhizinesi munharaunda dzemahombekombe. Kana zvikaitika panguva imwe chete semadutu makuru, mafashamo anogona kunyanya kupararira uye kukuvadza kune zvese zvakavakwa nevanhu uye zvakasikwa zvivakwa.

Uye masaisai emambo ari kuunza marudzi ese ekutarisisa nekuda kwekukwira kwegungwa. Semuyenzaniso, Yunivhesiti yeWashington Dhipatimendi reEcology inokurudzirawo kuti vagari vabatane mukutarisa kukanganisa kwemafungu epamusoro kuburikidza neayo. Washington King Tide photo initiative.

Mambo wemwedzi uno anopindirana nekuburitswa kweimwe itsva shumo kubva kuUnited of Concerned Scientists iyo inopa kufanotaura kutsva kwemafashama emvura nekuda kwekukwira kwegungwa; nekuwanda kwezviitiko zvakadaro zvichiwedzera semuenzaniso kusvika kupfuura mazana mana pagore kuWashington, DC neAlexandria pamwe nemhepo yePotomac pakati pezana ramakore.

Kutarisira nzvimbo itsva dzemafashamo, kunyange dzenguva pfupi, chinhu chimwe chete chekuchinjira kumamiriro ekunze. Zvinonyanya kukosha kunzvimbo dzemumadhorobha uko kudzika kwemvura yemafashama hakungosiyi kukuvara kwezvivakwa zvevanhu, asi zvakare kunogona kutakura chepfu, marara, uye sediments kumvura yemahombekombe uye hupenyu hwegungwa hunotsamira pazviri. Zviripachena, tinofanira kuita zvatinogona kuronga zviitiko izvi uye nzira dzekudzikisa kukuvadzwa uku sezviri kutanga kuita dzimwe nharaunda. Zvakakoshawo kuti titarise masisitimu echisikigo mukugadzira marongero edu emunharaunda, kunyangwe isu tichishandira kugadzirisa zvakakura zvinokonzeresa shanduko yemamiriro ekunze uye kukwira kwemvura yegungwa. Uswa hwegungwa, mikoko, uye nzvimbo dzine mvura dzemumhenderekedzo yegungwa zvose zvinogona kubatsira kuderedza mafashamo—kunyangwe semvura zhinji yemunyu yenguva dzose ichigona kukanganisa masango emurwizi nedzimwe nzvimbo dzekugara.

Ndakanyora kazhinji nezve nzira dzakawanda dzatinofanira kunge tichifunga pamusoro pekushanduka kwemamiriro ekunze uye makungwa ane hutano uye hukama hwevanhu negungwa. Mafungu emvura anotipa chiyeuchidzo chokuti pane zvakawanda zvatinokwanisa uye zvatinofanira kunge tichiita kuti tisangane nekuchinja kwegungwa, kemikari yegungwa, uye tembiricha yegungwa. Join us.
