Siyazi ukuthi ngokufudumala kwembulunga yonke amazinga okushisa akhula njalo ngonyaka. Kangangoba amagagasi okushisa ehlobo aphawule amazinga okushisa amasha ezindaweni eziningi zomhlaba. Elinye lamagagasi okushisa akhunjulwa kakhulu yi- Juni 2019 igagasi lokushisa lapha eSpain amazinga okushisa abo ayephezulu ebeka irekhodi. Ososayensi bahlaziye lesi senzakalo kabanzi ukuze basiqonde kangcono.
Ngalesi sizathu, sizonikezela lesi sihloko ukuze sikutshele ukuthi luyini ucwaningo mayelana negagasi lokushisa likaJuni 2019.
Ukuhlukaniswa kwezinhlamvu zomoya
Ku-meteorology, ekubonakalisweni okushisayo kwezixuku zomoya, ipharamitha yokushisa ivame ukusetshenziswa endaweni ephakeme engu-1500 m, ehambisana nezinga lokucindezela lika-850 hPa. Lokhu kwenziwa ngoba lolu ungqimba ngokuvamile lutholakala emkhathini okhululekile ngaphandle kongqimba oluvalekile lomkhathi futhi ngenxa yalokho akuthintwa kancane ukuthintana komoya nomhlabathi, nakuba endaweni yethu emathafeni nasezinkangala, ukushisa komhlaba kubhebhetheka. lelo zinga kusukela emini, ngakho ngokuvamile sisebenzisa izinga lokushisa elingu-12 UTC 850 hPUkuze uthole ireferensi, ungqimba olungaphezulu lomoya (noma ukupholisa ebusuku) ngesikhathi sokushisisa emini alukafiki ngokugcwele ezingeni lamamitha angu-1500 (noma ukupholisa ebusuku).
Ukwengeza, i-12 UTC iqondana nokwethulwa kokunye kweziphenyi ezimbili zasemoyeni ezenziwa emhlabeni wonke yi-National Weather Service nezinye izinhlangano ezihlobene, ezivame ukusebenza izikhathi ezingaphezu kwenkulungwane ngayinye ngamahora. Lezi radiosondes zasemkhathini zisetshenziswe amashumi eminyaka futhi idatha yayo isetshenziselwa ukuhlaziywa komkhathi, ukubikezela nokuhlaziya kabusha, phakathi kweminye imisebenzi.
Juni 2019 igagasi lokushisa
Ngalokhu kucatshangelwa kwangaphambilini, kusukela kudatha yokushisa engu-850 hPa kungenzeka ukuchaza isisindo somoya phezu kwe-peninsula (ikakhulukazi ethinta izifunda ezimaphakathi, ezisenyakatho nenyakatho-mpumalanga) nasentshonalanga yezwekazi lase-Europe ezinsukwini zokugcina zikaJuni 2019. Kulezi zifunda, izifunda African air mass ukuthi indiza phezu kwawo iyona efudumele kunayo yonke erekhodiwe ngoJuni okungenani eminyakeni engu-40 edlule. Ngisho nasezingxenyeni ezincane zendawo emisiwe, bekuyindilinga yomoya efudumele kunanoma iyiphi inyanga yonyaka kule minyaka engamashumi amane edlule. Njengoba kukhonjisiwe ezithombeni ezimbili zokuqala, ingxenye esenyakatho yenhlonhlo yayinezinga lokushisa elimangalisayo elingaphezu kuka-+10ºC ngoJuni 28, 2019, 850 hPa, ngokuhluke kakhulu eningizimu-ntshonalanga, lapho isisindo somoya sasivamile futhi kubanda kancane. eGulf of Cadiz.
I-air mass in the peninsula enyakatho-mpumalanga ifudumele kakhulu, kuyilapho EziQhingini zaseCanary umoya womoya usha noma ubanda, unesilinganiso esingavamile esingu -6 ºC.
Umehluko omkhulu oshisayo phakathi kwesisindo somoya wase-Atlantic kanye nesisindo somoya esindize entshonalanga yezwekazi lase-Europe ngesonto eledlule likaJuni 2019 kungenxa yokuba khona kwemodi emile esanda kushicilelwa ye-"planetary wave resonance". Kukholakala ukuthi iyona mshini obangela izehlakalo zesimo sezulu esibi kakhulu ehlobo.
Ngaphezu komoya oshisa kakhulu phezu komhlaba, ukuba khona komoya obandayo enkabeni ye-Atlantic Trench, ohlangothini lwawo olusempumalanga lujova inani elikhulu lomoya ofudumele kakhulu eNtshonalanga Yurophu, kubangela lokhu kuphazamiseka kwezinga lokushisa.
Kukuphi lapho okwathinta khona kakhulu?
UJuni 2019 bekunguJuni oshisa kakhulu emlandweni womhlaba, ngokusho kwedatha ekhishwe ngoLwesibili. Ngokusho kukaCopernicus, insizakalo yokuguquka kwesimo sezulu yaseYurophu, i-thermometer ngoJuni kulo nyaka idlule irekhodi likaJuni 0,1 ngamadigri angu-2016. EYurophu, izinga lokushisa elijwayelekile ngoJuni laliyi-2 degrees ngaphezu kokujwayelekile.
Igagasi lokugcina lokushisa elithinte i isikhungo, inyakatho nenyakatho-mpumalanga yenhlonhlo kanye neziQhingi zaseBalearic phakathi kukaJuni 26 no-30 kwaba uJuni okhungathekisa kakhulu eminyakeni engama-40 edlule. Okutholwe ocwaningweni kuchaza ukushuba okungajwayelekile kwalesi sigameko futhi kuveza ukuthi amagagasi okushisa avame kakhulu futhi ashubile kulezi zifunda ezisanda kuthinteka ukushisa okukhulu.
Uma kuqhathaniswa nedatha yokushisa yama-27, 28 kanye nama-29 edlule ngosuku olufanayo lukaJuni phakathi kuka-1979 no-2018, kwaphawulwa ukuthi amanye amanani aqoshwe ngesikhathi sokushisa okuphezulu kwenyanga edlule ayephezulu kakhulu ezinhloko-dolobha eziyi-14. iSerie.
En Barcelona, Zaragoza, Bilbao, Pamplona, San Sebastian, Logroño, Huesca and Burgos, amazinga okushisa afinyelelwe ezinsukwini ezintathu ezibalulekile zegagasi lokushisa ayephezulu kakhulu ochungechungeni. Isimo saseMadrid kanye namaphuzu eSierra de Madrid naseTorrejón de Ardos, asikaze sishise njengaleyo nyanga kaJuni, futhi siqokomisa inani eliphakeme leVitoria, Lleida, Girona, Soria, Teruel neGuadalajara.
Emashumini amabili eminyaka okuqala aleli khulu leminyaka, inqwaba yomoya efudumele kaJuni, ebangela amazinga okushisa aphakeme ngendlela engavamile ezindaweni ezithintekile ngenxa yokushisa, yawela izikhathi ezicishe zibe yi-10 kunaseminyakeni emibili edlule yekhulunyaka eledlule, ngaphezu kokukhula imvamisa yeminyaka eyi-3,7 kuye kwengama-3,7 njalo ngeminyaka engama-30,7.
Imvamisa yezixuku zomoya ezifudumele kakhulu ezikhiqiza "izenzakalo zesimo sezulu" kanye namagagasi okushisa ngoJuni ziye zanda zisuka eminyakeni eyi-100 eminyakeni engu-20 yesibili yekhulu lama-10 kuya eminyakeni eyi-1,3 eminyakeni emibili yokuqala yaleli khulu leminyaka. Emashumini amabili eminyaka okuqala aleli khulu leminyaka, iziqephu zokushisa okuphezulu noma ukushisa okwedlulele zaziphindaphindeka ngokuphindwe kashumi kunaseminyakeni yesibili engamashumi amabili yekhulu lama-XNUMX, futhi umoya womoya ezweni lonke ehlobo wawuphakeme ngama-degree angu-XNUMX kunewokugcina. iminyaka eyishumi, ngaphandle kwaseCanary Islands, ngokunyuka kwama-degree angu-1,07. Ngokusho kwe-Aemet, zonke lezi ziphetho zihambisana nokuqagela kwezimo zokuguquguquka kwesimo sezulu okwenziwe emashumini ambalwa eminyaka.
Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana negagasi lokushisa langoJuni 2019
