2017 rave riri gore iro vazhinji vedu tichayeuka nekuda kwezvakasiyana zvinyorwa zvakatyorwa, pamwe nehuwandu hwezvinhu uye kukuvara kwevanhu kwakaitika. Pasina kupokana, izvo zviitiko zvine nyeredzi zvakanyanya gore rino izvo zvatiri kuda kuenda matutu anopisa, ane mwaka muAtlantic uchadzika munhoroondo yekuumbwa madutu gumi emvura inoteedzana akateedzana kuita chikamu chedutu.
Asi paive nezvimwe zviitiko zvatisingakwanise kukanganwa kana: semoto weCalifornia, kana nemhepo yakatakura jecha kubva mugwenga reSahara kuenda kuAmerica.
Nyika yedu inyika umo, iwe ungati, kuti zvese zvakabatana. Isu kazhinji hatifunge nezvazvo, asi zvinoitika munzvimbo imwe zvinogona kukanganisa pasirese. Madutu eAtlantic anoumba pedyo nekondinendi yeAfrica; zvisinei, zvinokanganisa America.

Zvakaitika sei izvi? Kuzviratidza, NASA's Goddard Center yaburitsa vhidhiyo inoratidza. Mariri, dhata rakawanikwa kubva kumaseteraiti mukati megore rakasanganiswa nemamatechira mamodheru pane yekufananidza komputa.
Mhedzisiro iyi vhidhiyo ipfupi inoshamisa paunogona kuona kuti madutu makuru akagadzirwa sei, kwavakaenda uye kuti vakapedzisira vasisina simba sei. Uye zvakare, iwe unozogona zvakare kuona kuti mhepo dzakatakura sei zvidimbu zvidiki zveguruva, gungwa munyu (mubhuruu), jecha kubva kugwenga reSahara kuenda kuAmerica (mune brown) uye utsi kubva kumoto unoburitswa muPacific (mune grey).
