Madutu ndiwo mamiriro emamiriro ekunze ayo, anoonekwa nemifananidzo yesataneti, anoshamisa zvechokwadi. Asi pasi zvinhu zvinochinja. Zvinogona kukonzera kukuvara kwakakomba, kusvika pakuti panogona kutove nekufa.
Kwegore rino, sekutaura kwenyanzvi, gumi nemaviri madutu ekunze anotarisirwa muAtlantic, ayo mashanu achava madutu, maviri acho akasimba kwazvo, mumwaka une chiitiko chicha average. Mwaka wedutu unotanga zviri pamutemo muna Chikumi 1.
Gore rino kuumbwa kwedutu kuchakanganiswa nekuderera kwesimba reEl Niño uye netembiricha yakaderera muNorth Atlantic.

Klotzbach nechikwata chake vanoita zvavanofungidzira gore rega rega. Ichi chidzidzo chinoitwa nekuongorora makore makumi maviri nemapfumbamwe enhoroondo dhata pamusoro pemupupuri. Ye29, vanofanotaura madutu gumi nemaviri ayo, pamwechete, ichave ichishanda kwemazuva makumi mashanu. Pane gumi nevaviri ava, pachave nevashanu vanozove madutu, maviri acho akasimba kwazvo.
Klotzbach akaenderera mberi achidaro inokwana dutu kuti riite kudonha kwaro kuti riitwe semwaka unoshanda wenzvimbo iyoyokunyangwe hazvo chiitiko chedutu chakafanotaurwa, saka zvakakosha kuti utarise kune nyevero yemamiriro ekunze kuitira kuti matambudziko erudzi rupi zvarwo asauye.
