Hitaande kala fotde 80 wuubiliiru ŋoriiru (cyclone tropical) ina jibinee e leydi men hee dow diƴƴe gonɗe e nokkuuji gonɗi hakkunde ŋori leydi.
Hol ko firti wuubiluuru ?
Hitaande kala, waylowaylooji weeyo keewɗi, bonɗi, ina kewa e nokkuuji gonɗi hakkunde ŋori leydi men ndii, waylowaylooji ganndiraaɗi « guubiliiji ». Ɗee dille weeyo njirlortoo ko no njamkon montoor nii (nano feewde ñaamo) so tawii ko e peccol worgo ngoni. So tawii noon ko e peccol rewo (peccol ngon-ɗen ngol) ɗe njirlortoo ko bannge luutndiiɗo njamkon montoor (ñaamo feewde nano).
Ñoƴƴere (tiɗɗo, dummbo) weeyo ina famɗi ɗo hakkunde yiriinde ndee. Njaajeendi dille ɗee ina wona 500 haa 1 000 kiloomeeteer (tuggi Nuwaasoot haa Neema). Wuddu (hakkunde) dille ɗee, ɗo wiyetee “yitere wuubiliiru nduu” ina yiyoo e nate ɗe satelitaaji ƴetti. Njaajeendi yitere ndee heewi wonde ko hedde kiloomeeteruuji 30 haa 60 (heen sahaaji ina yettoo 150 km); ko nokku deeƴɗo (alaa toɓo, kenal leefkal).
Woni e nokku taariiɗo yitere ndee ko duule mawɗe (kaaƴe) ɗe tooweeki mum waawi yettaade 12 haa 15 km. Ngalɗoo ‘’ɓalal’’ duule alaa ko ɓuri ɗum heewde bonannde : njaaweeki keneeli mayre ina mbaawi yettaade 300 km/w, tee toɓooji mum ko ɗuufeeji (yeru, en nder waktuuji 24 toɓo (ñalawma) to duunde Réunion caggal nde wuubiliiru rewi ɗoon, toɓii ko ina wona meeteruuji 2 ndiyam).*
- *Tesko : 100 mm toɓo e nokkuuji men, heewi wonde ko ngatamaaje mawɗe, tuɗnooje beeli, kelooje kuɓeeje, waɗa waameeji degginooji jawdi e kullon ekn… Ndaa 2m= 2 000 mm. Ɗum noon ina sowoo ngatamaaje kaal-ɗen ɗee laabi 20 !
Guubiliiji ina pinnina diƴƴe, pinne bonɗe :
– Henndu nduu ina ummina bempeƴƴe, ɗe nganndu-ɗaa kam en ɓuri henndu wuubiluuru nduu yaawde, sibu aɗe mbaawi daɗde ndu fotde 1 000 km (bempeƴƴe ɗee ina njahra e Nuwaasoot, tawa henndu jibinndu ɗum en nduu, yahrata ko Neema).
– Ƴero geec diwtungo aadaa, anndiraango “ƴero wuubiluuru” : kam woni huunde ɓurnde hulɓinaade e bonde ardoore e wuubiluuru.
So njaaweeki henndu yirlotoondu nduu e sawndooji nehaande ndee (yitere ndee) ina hulɓinii, dirto (déplacement) wuubiluuru nduu ko hedde 30 haa 30 km/h (ina leeli).

- So njaaweeki henndu nduu jaasii 63km/w, wiyee dumbitorde ŋoriire ;
- Hakkunde 63 e 117km/w, wiyee wuubiliiru ŋoriiru ;
- So ɓurii 117km/w wiyee wuubiliiru.
Wuubiliiru walla Uragaa, walla tifoŋ ?
Guubiliiji ina njogii inɗe keewɗe e fawaade e deedal guubiliiwal ɗo ɗi nguttata ɗoo. Nii woni, helmere Wuubiliiru (walla wuubiliiru ŋoriiru) herorii ɗum tan ko geec iñnjeejo e pasifiijo worgo. So tawii ko to Atlantik rewo walla to Pasifik rewo guubiliiji ɗii mbiyetee ko Uragaa (Ouragan); so tawii noon ko to Pasifik hirnaange rewo wiyee Tifoŋ (typhon).
