1. Okutegeera Okuzibikira kw’omukutu gw’empewo ogw’okungulu okusemberera okuva mu kussa ggaasi ow’ebbugumu erisukkiridde¶

Mu PyroCb downburst oba entrapment, okussa empewo ebuguma ennyo (> 150 C / . 300 F) nga zitabuddwamu ggaasi z’obutwa eziyitibwa pyrolysis ggaasi ( .carbon monoxide, hydrogen cyanide, acrolein) kireeta okuzimba amangu mu bbugumu mu kkubo ly’empewo erya supraglottic (epiglottis, aryepiglottic folds, n’emiguwa gy’eddoboozi): - Obubonero Obukulu Obulabula (15-to-60-Minute Airway Closure Window): - Enviiri z’ennyindo oba ebisige ebiyimbiddwa, enfuufu okwetoloola akamwa oba ennyindo; - Omusulo ogulimu kaboni (omuddugavu, ogulimu enfuufu) ng’osesema; - Eddoboozi ery'okuwuuma, erya raspy, oba "hot-potato", okusesema okw'ekikomo, oba okw'amaloboozi amangi inspiratory stridor; - Okuzimba emimwa, olulimi oba ensingo. - Ekikolebwa mu bwangu: Kuba essimu 911 / . 000 / . 112 / . 999 nga Priority-1 Airway Emergency. Omulwadde mukuume ng'atudde nga yeegolodde (High Fowler's / Tripod position) okukendeeza ku gravitational edema mu mumiro, okugaba high-flow humidified 100% oxygen singa ebaawo (nga era eyanguya carbon monoxide washout emirundi 5), era otambuze mu bwangu okutuuka mu kitongole ky’amangu oba helicopter rendezvous ekuli okumpi abasawo basobole okukola early endotracheal intubation nga okuzimba tekunnasiba ddala trachea okuggalawo.

2. Okwokya okw’ebbugumu n’okusaanuuka Engoye ezikoleddwa mu ngeri ey’ekikugu¶

• Cool the Burn, Warm the Patient: Fukirira olususu olw'ebbugumu n'amazzi amazzi ag'okunywa agakulukuta agannyogoga (15 C to 20 C / . 59 F to 68 F) okumala eddakiika 20 ezijjuvu okuyimiriza okukula kw’ebbugumu ly’olususu. Tokozesangako mazzi ga ice oba ice (ekivaako okuzimba emisuwa n’okunyweza tissue necrosis, plus ekivaako hypothermia mu kwokya okunene).
• TOSOLOLA Nnyambala Ezisaanuuse: Singa engoye za poliyesita, nayirooni, oba ebyoya by’endiga zisaanuuse mu lususu mu kiseera ky’omuzira ogw’amaanyi, ginyogoze bulungi n’amazzi era osale okwetooloola empenda z’olugoye ezitabuddwa, olekewo obuveera obusaanuuse obunywevu mu kifo kyakyo okusobola okulongoosebwa mu kifo we kyokeddwa.
• Bikka Cling Film / Clean Dry Sheet: Oluvannyuma lw’okunyogoza, teeka amaka amayonjo plastic cling wrap (food wrap) longitudinally ku kifo ekyokeddwa (tozinga nnyo ku kitundu ky’omubiri nga tourniquet, anti ebitundu ebyokeddwa bizimba nnyo) okuziyiza obulumi okuva mu mpewo n’okuziyiza amazzi okufuumuuka (laba okwokya era okwokya ennyo n’okufuuwa eddagala).

3. Ember y’amaaso & Alkaline Wood-Evvu Flush¶

Evvu lya PyroCb eribuuka (wet wood ash has an alkaline pH of 10 to 12) ne cinders ezibuguma zireeta okunyiga ennyo mu maaso n’okwokya amaaso mu alkali. Okunaaba amaaso amangu ddala n’omunnyo omungi ogutaliimu buwuka oba amazzi amayonjo ag’okunywa mu ccupa okumala eddakiika 15 ng’oyiringisiza ebikowe by’amaaso, tosiiga maaso, era bikke eriiso erifunye obuvune obw’amaanyi n’engabo ekuuma (laba eriiso ekintu ekigwira, okunyiga kw’amaaso, n’okuweta okumasamasa).

Ebibuuzo ebitera okubuuzibwa¶

Ekire kya pyrocumulonimbus (PyroCb) kye ki, era oyinza otya okutegeera ekimu ng’oli ku ttaka?¶

Pyrocumulonimbus (PyroCb), ekitongole ky’ensi yonna ekinoonyereza ku mbeera y’obudde ekyatuumibwa erinnya mu butongole cumulonimbus flammagenitus, kibuyaga ow’omuliro okuva ku muliro ogutondebwawo ng’omuliro ogw’amaanyi ogw’omu nsiko gusitula ebbugumu, omukka n’obunnyogovu kiromita 10 ku 16 (fuuti 33,000 okutuuka ku 53,000) mu troposphere eya waggulu ne stratosphere eya wansi. Okuva wansi, osobola okutegeera PyroCb ekula ng’empagi y’omukka eya kitaka enzirugavu oba omuddugavu esituka mu vertikal ng’okubutuka kw’olusozi n’ekola ekire ky’ekire kya kalittunsi ekyeru ekimasamasa, ekibuguma waggulu (pyrocumulus) oluvannyuma ne kifuumuuka ne kisaasaana waggulu ne kifuuka ekiwujjo, eky’omuzira eky’okubwatuka kw’enkuba, ekitera okuwerekerwako okubwatuka n’okumyansa munda mu mpagi y’omukka.

Lwaki okugwa kw’ekiwujjo kya PyroCb kireetera omuliro gw’omu nsiko okufuuwa amangu mu buli ludda omulundi gumu?¶

Nga PyroCb updraft enkulu etwala obukadde bwa ttani z’evvu, enfuufu, n’omukka gw’amazzi waggulu mu bbanga erya waggulu erifuuse omuzira, ebiwujjo bya ice n’obutundutundu bw’enkuba bituuka ekiseera ne bikula nga bizitowa nnyo nga updraft esobola okukwata waggulu, oba okufuumuuka ne bifuuka layeri y’empewo enkalu wakati mu kkubo wansi. Okunyogoza okufuumuuka kuleeta ensawo ennene ey’empewo ennyogovu ennyo munda mu mpagi y’omukka egwa butereevu wansi ku sipiidi ya kiromita 60 ku 100 buli ssaawa (okubutuka okukalu oba okubutuka). Empagi eyo egwa bw’ekuba ensi, efuumuuka ebweru diguli 360 mu buli ludda ku sipiidi y’omuyaga (kiromita 100 ku 160 buli ssaawa / mayiro 60 ku 100 buli ssaawa), n’ekuba omuyaga ogw’omuzira ogw’okwebungulula ogw’omuliro ogwokya waggulu w’empewo, okusala empewo, n’okukka omulundi gumu.

"Ekibuyaga w'omuliro" mu kiseera ky'omukolo gwa PyroCb kibuyaga ddala oba sitaani enfuufu ennene yokka ey'ennimi z'omuliro?¶

Wadde ng’empagi ezisinga eziwuuta ku muliro gw’omu nsiko zibeera za muliro mu kitundu (obugazi bwa mita 1 ku 30, ezimala eddakiika ntono, okufaananako ne sitaani z’enfuufu), PyroCb esobola okuvaamu omuyaga omutuufu ogw’omulembe gwa supercell. Omuyaga ogw’amaanyi ogw’okubwatuka kw’empewo ogwa PyroCb bwe gugolola okusala kw’empewo okw’okwebungulula mu musingi gw’ebire, gusobola okwekulukuunya waggulu omuyaga ogw’omuliro ogw’ekika kya mesocyclonic nga guweza mita 300 ku 500 (fuuti 1,000 ku 1,650) obugazi ng’empewo esukka kiromita 220 ku 265 buli ssaawa (135 ku 165 mph, EF2 okutuuka ku EF3 amaanyi), nga bwe kyawandiikibwa nga bakozesa Doppler radar ne NWS storm surveys mu kiseera ky’omuliro gwa Carr mu 2018 e Redding, California (143 mph / 230 km/h) n’omuliro gwa Loyalton mu 2020 mu California, ekitongole ky’ebyobulambuzi mu ggwanga gye kyafulumya Tornado Warning eyasooka mu byafaayo ku pyrogenic vortex.

Lwaki tolina kwesibira mu kisenge ekya wansi oba mu kabokisi akataliiko madirisa ng’odduka okuva ku muliro gw’omu nsiko oba okubutuka kwa PyroCb?¶

Mu kibuyaga ow’omutindo oguzingibwa enkuba, ekisenge ekya wansi oba ekibbo eky’omunda ekitaliiko madirisa kye kifo ekisinga okuba eky’obukuumi. Mu muliro ogw’omu nsiko oba PyroCb downburst ember blizzard, okwesibira mu kisenge mw’otosobola kulaba bweru kitta: empewo ezitambula kiromita 130 buli ssaawa zitera okumenya amadirisa oba okukaka embers okuyita mu mikutu gy’empewo ku mwaliiro ogw’okungulu, ne zikuma omuliro mu nnyumba ekubeetoolodde ate ng’omukka ogubuguma ennyo ne kaboni monokisayidi bijjuza munda. Bw’oba ​​osibidde mu maka agatalina ngeri gy’oyinza kusengukamu ku luguudo, nyweza mu kkubo ery’omunda okuva ku ndabirwamu mu kiseera ekitono kyokka eky’empewo ey’oku ntikko ey’eddakiika emu ku bbiri ey’ekiwujjo, olwo n’olondoola n’obunyiikivu ennyumba okulaba oba temuli biwujjo era obeere okumpi n’enzigi bbiri ez’ebweru ezikontana osobole okufuluma ku ttaka eriddugavu eryayokebwa edda mu kaseera ennimi z’omuliro enkulu ez’ebweru mu maaso we ziyita.
