Nastaje u vrlo intenzivnim grmljavinskim visoko razvijenim i vlagom bogatim kumulonimbusnim <a href="https://www.enciklopedija.hr/clanak/oblaci">oblacima</a>, najčešće u proljeće i ljeti, kada čestice leda nošene jakim uzlaznim i silaznim strujama nekoliko puta prolaze kroz debele slojeve oblaka i pritom stvaraju nove, više ili manje koncentrične slojeve leda. Kada težina zrna nadvlada jačinu uzlazne struje, zrna tuče ispadaju iz oblaka. Zbog velike mase zrna, njihovim udarcima mogu nastati goleme štete, prije svega na poljoprivrednim nasadima, vozilima pa i lakšim građevnim konstrukcijama.</p><p>Obrana od tuče zasniva se na načelu zasipavanja oblaka, s tla ili iz zrakoplova s pomoću raketa, s velikim količinama čestica srebrnoga jodida kako bi se u kumulonimbusnom oblaku stvorio velik broj malih ledenih čestica umjesto krupnih zrna tuče koja mogu izazvati velike štete. Još nije nedvosmisleno dokazano da je takav sustav obrane od tuče djelotvoran.</p> </div> </div> </div> <div class="container citiranje"> Citiranje: <p> tuča. <i>Hrvatska enciklopedija</i>, <i>mrežno izdanje.</i> Leksikografski zavod Miroslav Krleža, 2013. – 2024.
