Dukkanin wadannan guguwa da sikelin har zuwa manyan extratropical (tsarin matsin lamba) da Guguwa ta wurare masu zafi suna juyawa a cikin cyclonic. Juyawa a cikin waɗannan tsarin sikelin synoptic ya samo asali ne daga Tasirin Coriolis, amma tsawa da guguwa sun yi ƙanƙanta don a shafa su sosai. Abubuwan da aka saba amfani da su a nan yanki ne na matsin lamba, don haka iska da ke kewaye da ita tana gudana cikin yankin da ba shi da iska mai yawa wanda ke haifar da juyawa. Juyawa na tsawa kanta ana haifar da shi galibi ta hanyar iska mai tsaye, musamman juyawa a gefen agogo yayin da tsawo ke ƙaruwa (wanda ake kira bayanin martaba mai juyawa, kodayake bayanan martaba na iya faruwa tare da supercells na anticyclonic).

Matakai daban-daban na iya haifar da guguwa mai guba. Mafi sau da yawa su ne Guguwar tauraron dan adam na manyan guguwa waɗanda ke da alaƙa kai tsaye da guguwar guguwa da mesocyclone. Lokaci-lokaci guguwa ta anticyclonic tana faruwa a matsayin abokin anticyclone (Mesoanticyclone) zuwa mesocyclone a cikin guguwa ɗaya. Wannan yana da matukar wuya kuma an rubuta shi ne kawai sau 5.[1] Anticyclonic guguwa na iya faruwa a matsayin guguwa ta farko tare da mesocyclone kuma a ƙarƙashin girgije mai juyawa. Har ila yau, anticyclonic supercells (tare da mesoanticyclone), wanda yawanci guguwa ne da ke rabuwa da motsawa zuwa hagu na motsi na guguwar iyaye, kodayake da wuya a haifar da guguwa, suna haifar da gwagwarmayar guguwa. Akwai karuwar abin da ya faru na guguwar guguwa da ke da alaƙa da guguwar wurare masu zafi, kuma mesovortices a cikin muryoyin baka na iya haifar da guguwa na guguwa.[2]
