Hasa Njia Same na Ondoka Mara nyingi sana bapa (kuharibiwa, dhaifu) kawaida maumbo (RDF - nasibu downed formations) Kwamba si tu mifumo yote ya mara kwa mara karibu husishwa kuandamana, lakini Zaidi ya 99.999% ya kesi (pia mraba maeneo) kutokea kabisa kujitegemea . isipokuwa kwa sheria Ikielezewa ni vimbunga, Tornadoes na mafuriko, lakini Wao ni pamoja na katika takwimu - Kwa sababu Sababu Thesis na si kuondoka mazao bapa (kuharibiwa, dhaifu), lakini kabisa uliharibu, Na Wao Je Si Inajulikana kama tu " mbaya hydrometeorological masharti ", lakini kama maafa halisi ya asili.
