Copernicus: Antarctic gungwa rechando rinosvika nguva shoma munaFebruary - Chechipiri inodziya yechando pane rekodhi muEurope.

Pamusoro pemhepo tembiricha inomaly yaFebruary 2023 inoenderana neavhareji yaFebruary yenguva 1991-2020.[1]

Kunobva data: ERA5. Chikwereti: Copernicus Climate Change Service/ECMWF.

The Copernicus Climate Change Service (C3S), yakaitwa neEuropean Center for Medium-Range Weather Forecasts panzvimbo yeEuropean Commission nemari inobva kuEU, inogaro budisa zvinyorwa zvemwedzi zvemamiriro ekunze zvichitaura nezvekuchinja kuri kuitika pasi rose. pamusoro pemhepo tembiricha, gungwa ice cover uye hydrological variables. Zvese zvakashumwa zvakawanikwa zvakabva paongororo dzakagadzirwa nekombuta uchishandisa mabhiriyoni ezviyero kubva kumasetellite, ngarava, ndege uye zviteshi zvemamiriro ekunze pasi rese. 

Kukadzi 2023 - tembiricha yakakwira: 

·       Kukadzi 2023 yaive yechishanu pakudziya pasi rose

·       Nzvimbo zhinji dzeEurope dzaive nemhepo yepamusoro-soro, kunyanya kuchamhembe kweNorway neSweden, nenharaunda yeSvalbard.

·       Tembiricha iri pamusoro-avhareji yakaitika kumabvazuva kweUnited States, kuchamhembe kweRussia, uye kuPakistan neIndia. 

·       Tembiricha yepasi-avhareji yakaonekwa muIberian Peninsula, Türkiye, kumadokero kweUnited States, Canada, kuchamhembe kwakadziva kumabvazuva kweRussia, uye kuchamhembe kweAustralia.

Kukadzi 2023 - Mazai echando egungwa:

·       Aizi yegungwa reAntarctic yakasvika pamwero wayo wakadzikira pamwedzi murekodha yedata resetiraiti, pa34% pasi peavhareji yaKukadzi, zvichityora rekodhi yapfuura yaFebruary 2017.

·       Antarctic daily sea ice extent yakasvikawo yakaderera, kudarika rekodhi yakamboiswa muna Kukadzi 2022.

·       Mazaya echando emugungwa aive ari pasi peavhareji muzvikamu zvese zveSouthern Ocean.

·       Aizi yegungwa reArctic yanga iri 4% pasi peavhareji, iri pachinzvimbo chechipiri chakaderera muna Kukadzi mune rekodhi yedata resethelaiti, pamwe chete naFebruary 2 na2016.

·       Mazaya echando emugungwa reArctic akanga akawanda ari pasi peavhareji munharaunda yeBarents Sea neSvalbard.

[1]Iyo yakakura yakanaka tembiricha inomalies yaFebruary 2023 kuchamhembe kweItari ine hukama nenyaya yedata muERA5 uye inofanirwa kutariswa nekuchenjerera. Dambudziko riri munharaunda uye hariite kuti nhamba uye chinzvimbo cheEurope.

Nguva dzakatevedzana dzepamwedzi dzinoreva Antarctic Sea ice extent inomalies yemwedzi yese yaFebruary kubva 1979 kusvika 2023. Iwo anomalies anoratidzwa sechikamu cheavhareji yaFebruary yenguva ya1991-2020. Kunobva data: EUMETSAT OSI SAF Sea Ice Index 2.1. Chikwereti: Copernicus Climate Change Service/ECMWF/EUMETSAT.

Sekureva kwaSamantha Burgess, Mutevedzeri Mukuru weC3S, "Ruzivo rwedu rwemazuva ano runoratidza kuti aizi yegungwa reAntarctic yakasvika padanho rayo rakaderera pamakore 45 edhata resetiraiti. Aya mamiriro echando emugungwa akaderera anogona kuva nezvakakosha pakugadzikana kwemasherufu echando eAntarctic uye pakupedzisira kukwira kwegungwa repasi rose. Polar ice caps chiratidzo chakajeka chedambudziko remamiriro ekunze uye zvakakosha kunyatsoongorora shanduko dziri kuitika ikoko. "

Nguva yakatevedzana yeAntarctic yezuva nezuva yegungwa ice chiyero che2017 (bhuruu), 2021 (yero), 2022 (tsvuku) uye 2023 (dema). Iyo dhizaini inoratidza mune grey mimvuri iyo yemazuva ese yepakati (yakasimba mutsara), interdecile renji (mwenje shading) uye interquartile renji (yakasviba shading) panguva ya1991-2020, pamwe nehushoma hwezuva nezuva uye huwandu mukati me1979-2022 (dashed mitsetse).

Hydro yakanakisa yaFebruary 2023:

·       Muna Kukadzi 2023, nzvimbo zhinji dzekumadokero nekumaodzanyemba kweEurope dzakasangana nemamiriro ezvinhu akaoma-kupfuura avhareji, matunhu akati wandei akaona hunyoro hushoma hwevhu.

·       Kunze kweEurope, kwakanga kwakanyorova kudarika avhareji kumaodzanyemba kweU.S.A, matunhu eRussia, nechepakati nekumabvazuva kweAsia, kuchamhembe kweAustralia, kumaodzanyemba kweBrazil, maodzanyemba kwakadziva kumabvazuva kweAfrica neNew Zealand. Muzviitiko zvakawanda, kunaya kwakanyanya, dzimwe nguva kwakabatana nemadutu, kwakakonzera mafashamo. 

·      Pakati pematunhu ainyanya kuoma kupfuura avhareji paiva nezvikamu zveSouth America, idzo dzakasangana nekusanaya kwemvura nemoto wesango, pamwe nekumaodzanyemba kweAustralia uye kumadokero kwekumaodzanyemba kweAfrica. 

Anomalies mukunaya, hunyoro hwemhepo hwepamusoro, hunyoro hwevhoriyamu hwepamusoro 7 cm yevhu uye tembiricha yemhepo yepamusoro muna Kukadzi 2023 maererano neavhareji yaFebruary yenguva 1991-2020. Kusviba kwegrey shading kunoratidza uko hunyoro hwevhu husina kuratidzwa nekuda kwekuvharwa neaizi kana kunaya kwemamiriro ekunze.Data source: ERA5 Credit: Copernicus Climate Change Service/ECMWF.

Boreal yechando 2022/2023

·       Nguva yechando ndiyo yaive yechipiri kudziya zvakanyanya parekodhi kuEurope, ine tembiricha iri pamusoro-soro kumabvazuva kweEurope nemativi ekuchamhembe kwakadziva kumabvazuva kweEurope.

·       Chando cheBoreal chaipisa kudarika avhareji munzvimbo zhinji dzekumadokero nekumaodzanyemba kwakadziva kumabvazuva kweEurope, pamwe nematunhu eRussia. Kunyorova-kupfuura-avhareji mamiriro akagadzwa pamusoro pezvikamu zveIberia uye munzvimbo huru yekumaodzanyemba kwakadziva kumadokero kusvika kuchamhembe kwakadziva kumabvazuva kwekondinendi. 

·       Kwakanga kune mvura kudarika avhareji zvakare kumadokero kweNorth America, kumadokero kweRussia, chikamu chepakati Asia, kuchamhembe kweAustralia, kumaodzanyemba kweBrazil nekumaodzanyemba kweAfrica. Matunhu akaoma-kupfuura-avhareji aisanganisira Mexico, mazhinji eCentral Asia, Nyanga yeAfrica, maodzanyemba eAustralia uye yakawanda yeSouth America.
