Kubva muna Nyamavhuvhu 19, 2014, kwave nekatanhatu nhamba yenzvimbo dzinopisa dzinopisa muEast Pacific Basin zvichienzaniswa neAtlantic Basin: 12 kupesana ne2.
Kunyange zvazvo Atlantic ingangobata kusvika pamwero wakati pamusoro pechiyero chemwaka, musiyano unogona kuramba wakakura.
KuMabvazuva kwePacific, AccuWeather iri kutarisira ichangobva kuumbwa Tropical Storm Lowell kuti ichitevedzerwe neyakaomesesa inonaya mvura mukupera kwesvondo rino kusvika svondo rinouya.
Sekureva kwaAccuWeather Hurricane Nyanzvi Dan Kottlowski, "Hunyoro kubva kune chimwe kana zvese zviri muEast Pacific hunogona kuyerera kusvika kumaodzanyemba kwakadziva kumadokero kweUS kutanga gare gare svondo rino uye izvi zvinogona kukonzera kunaya kwemvura."
Kudivi reAtlantic, gungano remabhanan’ana rinobva kuEast Coast yeUnited States rinozotariswa kuti rifambire mberi mukupera kwesvondo rino. Imwe hurongwa inogona kuumba kure kumaodzanyemba kwakadziva kumabvazuva pamusoro peAtlantic Basin, kubva kune imwe yezvipingamupinyi zvitatu zvichienda kumadokero.
Pane mukana wekusimudzira muCaribbean neGulf yeMexico svondo rinouya kubva kune imwe yenyonganiso yasara. Mamiriro ezvinhu anogona kunge akanakira budiriro munzvimbo iyi nesvondo rinouya.
Kubva pakutanga kwechirimo ichi, AccuWeather yanga ichifanotaura nezve yakaderera-kupfuura-avhareji nhamba yemadutu anopisa uye madutu muAtlantic, pamwe nepamusoro-avhareji nhamba yakafanana kuEast Pacific.
Sekureva kweNyanzvi yeLong Range Paul Pastelok, "Zvisinei nenhamba yakadzikira yeAtlantic, pachine njodzi yekurohwa nepakati nekumadokero kweGulf coast uye pamwe nemhenderekedzo yekumaodzanyemba kweAtlantic mukati memwedzi mishoma inotevera."
Mwaka wedutu rinoenderera mberi kusvika Mbudzi 30 muAtlantic neEastern Pacific. Hazvigoneki kuti dutu remunzvimbo dzinopisa kana dutu remhepo riitike muna Zvita.
Paavhareji, kune gumi nerimwe ane mazita masisitimu (dutu rinopisa nemadutu) pagore muAtlantic uye gumi neshanu muEast Pacific.
Kunyange zvazvo Eastern Pacific iri pamberi pehurongwa, Atlantic iri kunyatsomhanya pedyo nepainofanira kunge iri panguva ino mumwaka maererano nehuwandu hwemhepo inopisa uye dutu.

"Kudzikira kwakanyanya kwenzvimbo dzinopisa kunogona kunge kwakakonzerwa, muchidimbu, nemhedzisiro yeEl Niño," Kottlowski akadaro.
Munguva yeEl Niño, mvura dziri pamusoro pePacific dzinopisa dzinodziya kupfuura avhareji uye dzinogona kutsigira gadziriro dzakawanda dzinopisa.
Zvichakadaro, pamusoro peAtlantic panguva yemuenzaniso weEl Niño, kunowanzova nenzvimbo yemhepo ine simba iri mudenga mumhenderekedzo yeNorth America. Uku kugera kwemhepo hakungogumiri pakusimba kwenzvimbo dzinopisa asi kunogona kudzivirira kuumbwa kwadzo.
"Zvikonzero zvinowedzera kupfuura zvinogona kutsanangurwa neEl Niño," Kotlowski akadaro.
“Kuwedzera kune nzvimbo yakakura zvisina kujairika yekugerwa kwemhepo kubva kuCaribbean ichipfuura nechikamu chekumadokero kweAtlantic, kwave kunewo nzvimbo yakakura uye isingachinji yemhepo yakaoma, huruva nemvura inotonhorera.
Mhepo yakaoma iri kupomba nenzvimbo yakakura kwazvo yekumanikidza kwakanyanya kuri pakati peAtlantic.
Mhepo yakaoma yave ichitora huruva kubva kuAfrica neSpain apo neapo. Zvinhu zviviri izvi zvinoshanda kurwisa mvura inonaya uye madutu ayo anotanga atungidza masisitimu emunzvimbo dzinopisa zvozobvumira kuti zvibudirire.
"Kutenderera kwakatenderedza nzvimbo iyoyo ine simba guru hakuna kungomanikidza nzvimbo dzinopisa zvisina kujairika kumaodzanyemba kweAtlantic, asi zvakare kukonzera mvura inotonhorera kubva pakadzika kuti ikwire kumusoro," akadaro Kottlowski.
Mvura inotonhorera yepamusoro inononotsa kusimukira kwenzvimbo dzinopisa uye zvinogona kukonzera kupera simba kwechamupupuri kana kuti dutu remhepo.
Pane zvimwe zvinokonzeresa kuwanda kwenzvimbo dzinopisa dzepasi mugomba regungwa rinopesana nerimwe.
Chimwe chiitiko chakawanikwa mukutanga 1970s, inozivikanwa seMadden-Julian Oscillation (MJO).
Kuyerera kwehunyoro uku kunofamba zvishoma nezvishoma kuenda kumabvazuva kutenderedza pasi rose munzvimbo dzinopisa uye kunogona kutungamira mukupisa kwezvimiro zvakati wandei munguva pfupi. Kure neMJO, panogona kuve nekunyarara mune mamwe mabheseni.
"Kuputika uku kunogona kutsanangura kukwira kwenzvimbo dzinopisa dziri kumabvazuva kwePacific kufungidzira svondo rinotevera, uye zvinokwanisika zvinogona kutungamira mukukwira muAtlantic nguva pfupi yadarika," akadaro Kottlowski.
Zvimwe zvinokanganisa masisitimu emunzvimbo dzinopisa zvinosanganisira kuchinjika kwetembiricha yemugungwa muAtlantic uye mune dzimwe nzvimbo dzePacific izvo zvinogona kutora kubva pamwedzi kusvika kumakore kusvika gumi kana kupfuura.
