A pyrocumulonimbus (PyroCb), yakadanwa zviri pamutemo kuti cumulonimbus flammagenitus neWorld Meteorological Organisation, imhepo inokonzeresa moto inogadzirwa apo moto wemusango wakakura unosimudza kupisa, utsi, uye hunyoro makiromita gumi kusvika gumi nematanhatu (33,000 kusvika 53,000 kusvika 53,000 troposphere) kumusoro uye pasi pasi pasi pasi. Kubva pasi, unokwanisa kuziva PyroCb irikuridzika apo chiutsi chakasviba kana chitema chinosimuka chakamira sekuputika kwegomo rogadzira chivharo chegore rinopenya, rinofashaira cauliflower chena pamusoro (pyrocumulus) rinobva raita flat uye richipararira kumusoro kuita fibrous, ice mabhanan'ana mabhanan'ana, anowanzo kuperekedzwa mukati memubvumo wehutsi nemheni.

Nei PyroCb plume ichidonha ichikonzera kuti moto wesango uvhuvhute kumativi ese kamwechete?¶

Sezvo hurefu hwePyroCb updraft hunotakura mamirioni ematani emadota, soot, uye mhute yemvura kumusoro kumhepo inotonhora yekumusoro, makristasi echando uye zvimedu zvemvura zvinopedzisira zvakura zvakanyanya kuti iyo updraft irambe ichikwira mudenga, kana kunyungudika ichipinda mudungwe remhepo yakaoma pakati-kudzika. Kutonhodza kwemvura kunoumba homwe hombe yemhepo yakakora, inotonhora mukati membiru yehutsi inodonha yakananga pasi pa60 kusvika 100 km/h (kuoma kwe microburst kana downburst). Kana mbiru iyi inodonha ichirovera pasi, inorovera kunze madhigirii 360 kumativi ose ichimhanya nechamupupuri (100 kusvika 160 km/h / 60 kusvika 100 mph), ichivhuvhuta chamupupuri chakati chechetere chemazimbe anopfuta pamusoro pechamupupuri, chamupupuri, uye mhepo panguva imwe cheteyo.

Ko "chamupupuri chemoto" panguva yechiitiko chePyroCb chamupupuri chaicho kana kungova guruva hombe remoto?¶

Nepo makoramu mazhinji anotenderera pamoto wemusango ari enzvimbo dzemoto mhepo (1 kusvika 30 metres yakafara, inogara maminetsi mashoma, yakafanana neguruva dhiyabhorosi), PyroCb inogona kuburitsa chaiyo supercell-style chamupupuri. Kana mabhanan'ana ePyroCb akasimudzira mhepo yakachinjika muhwaro hwegore, inogona kutenderedza mesocyclonic fire tornado 300 kusvika 500 metres (1,000 kusvika 1,650 tsoka) yakafara nemhepo inodarika 220 kusvika 265 km/h (135 to 65 mph, EF 3F muchidimbu, EF6 kusvika 135 F) neDoppler radar uye NWS dutu rekuongorora panguva ye2018 Carr Fire muRedding, California (143 mph / 230 km/h) uye 2020 Loyalton Moto muCalifornia, uko National Weather Service yakapa nhoroondo yekutanga Tornado Yambiro kune pyrogenic vortex.

Nei usingambofa wakazvivharira mukamuri yepasi isina hwindo kana wadhiropu paunenge uchidzivirira kubva kumoto wemusango kana PyroCb yakadzikira?¶

Muchamupupuri chakajairwa-chakaputirwa nemvura, imba yepasi isina hwindo kana wadhiropu yemukati ndiyo nzvimbo yakachengeteka kuva. Mumoto wemusango kana kuti PyroCb inodzika mhepo ine blizzard, kuzvivharira mukamuri yausingaone kunze kunouraya: 130-km/h mhepo dzinowanzopwanya mahwindo kana kumanikidza marara kuburikidza nemhepo dzedenga, dzichibatidza imba yakakupoteredza uku utsi hunopisa uye kabhoni monoxide ichizadza mukati. Kana wakavharirwa mumba pasina nzira yekubuda nayo nemugwagwa, simbisa mukati memukoridho uri kure negirazi chete panguva pfupi yemhepo inovhuvhuta kubva paminiti 1 kusvika ku2, wobva wanyatsotarisisa imba yacho kuti ione moto uye gara pedyo nemagonhi maviri ekunze akatarisana kuitira kuti ugone kubuda uchienda kune yakatsva-yakatsva pasi pevhu apo moto wekunze wekunze unopfuura.
