Taayirka oo is beddela. Bartamaha jiilaalka, darawallo badan ayaa isticmaala taayirada xagaaga. Waa ammaan?
Marka loo eego daraasadaha iyo indho-indheynta siminaarada, waxay soo baxday in ilaa 35 boqolkiiba. darawaladu waxay isticmaalaan taayirada xagaaga xilliga jiilaalka. Tani waa is-khilaafsan - ilaa 90 boqolkiiba. sheeganaya in uu taayirada u beddelo taayirrada jiilaalka ka hor inta aanu da'in barafka ugu horreeya**. Poland waa dalka kaliya ee Midowga Yurub ee leh jawiga noocaas ah, halkaas oo sharciyadu aysan bixineynin shuruudaha lagu wado jiilaalka ama taayirada xilliga oo dhan ee xaaladaha dayrta-jiilaalka. Dhanka kale, marka loo eego daraasadda 2017 iyo 2018 Moto Data, 78 boqolkiiba. Darawalada Polish waxay door bidayaan soo bandhigida shuruuda lagu kaxeeyo xilliga qaboobaha ama taayirrada xilli-xilliyeedka oo dhan xilliga jiilaalka.
Komishanka Yurub wuxuu tilmaamay *** in 27 waddan oo Yurub ah oo soo saaray shuruudaha wadista ogolaanshaha jiilaalka (jiilaalka iyo sanadka oo dhan), tani waxay ahayd 46 boqolkiiba. yaraynta suurtagalnimada shil baabuur ee xaaladaha jiilaalka - marka la barbar dhigo ku wadista taayirrada xagaaga ee xaaladaha isku mid ah. Isla warbixintu waxay caddaynaysaa in hirgelinta shuruudo sharci ah oo lagu kaxeynayo taayirrada jiilaalka ay hoos u dhigto tirada shilalka dhimashada 3%, tani waa celcelis ahaan qiimaha - waxaa jira wadamo diiwaangashan hoos u dhaca tirada shilalka 20%.
- Darawalada laftoodu waxay rabaan inay soo bandhigaan shuruud ah inay u beddelaan taayirada jiilaalka - taasna mahadda leh, qof kastaa wuu la qabsan karaa xaaladaha cimilada isaga oo aan ka fikirin goorta la samaynayo iyo iyada oo aan la sugin barafka ugu horreeya. Cimiladayadu waxay soo jeedinaysaa in shuruudahan oo kale ay ahaato mid ansax ah Diseembar 1 ilaa Maarso 1 iyo shuruudi Noofambar iyo Maarso. Inta badan waxaad ka heli kartaa fikradda ah in nidaamyada badbaadada casriga ah ee baabuurku ku qalabaysan yahay ay ku filan yihiin in laga fogaado shil, iyo taayirrada aan door weyn ka ciyaarin badbaadada waddooyinka. Ma jiraan wax intaa ka badan oo khalad ah - taayirrada ayaa ah qaybta kaliya ee baabuurka ee la soo xidhiidha dusha wadada. Xilliga dayrta-jiilaalka, taayirada jiilaalka oo kaliya ayaa dammaanad qaadaya badbaado iyo qabsi ku filan. jiilaalka ama taayirrada xilli-xilliyeedka wanaagsan. Markaad ku wadeyso xawaare ugu hooseeya 29 km/saacadii xaaladaha barafka, taayirada jiilaalka waxay yareyn karaan fogaanta bareegga ilaa 50% marka loo eego taayirada xagaaga. Waad ku mahadsan tahay taayirada jiilaalka ee baabuur, SUV ama van, waxaan haysanaa is jiid jiid ka fiican oo waxaan si dhaqso ah u joojin doonaa waddooyinka qoyan ama barafka - taasina waxay badbaadin kartaa nolosha iyo caafimaadka! ayuu yiri Piotr Sarnecki, oo ah agaasimaha Ururka Warshadaha Taayirada Polish (PZPO).
Diiwaanada tijaabinta Auto Express iyo RAC ee taayirada jiilaalka **** waxay muujinayaan sida taayirada ku filan heerkulka, qoyaanka iyo sinnaanta dusha sare ay u caawiyaan darawalka inuu wado oo uu xaqiijiyo farqiga u dhexeeya taayirada jiilaalka iyo xagaaga kaliya maahan waddooyinka barafaysan. ama baraf leh, laakiin sidoo kale waddooyinka qoyan ee heerkulka dayrta:
- Waddada baraf leh marka aad ku socoto xawaare dhan 32 km/saacaddii, fogaanta bareegga ee taayirada jiilaalka ayaa 11 mitir ka gaaban taayirada xagaaga, taas oo dhererkeedu saddex jeer ka badan yahay baabuurka!
- Waddada barafku xawligeedu yahay 48 km/saacaddii, baabuur wata taayirrada xilliga qaboobaha waxa uu baabuurka ku jabin doonaa taayirrada xagaaga ilaa 31 mitir!
- Oogada qoyan ee heerkulku yahay +6°C, fogaanta baabuurka ee taayirada xagaaga waxay ka dheeraatay 7 mitir ka baabuurka taayirada jiilaalka. Baabuurta ugu caansan ayaa dhererkoodu ka badan yahay 4 mitir. Markii uu istaagay baabuurka taayarada jiilaalka, baabuurka taayirada xagaaga waxa uu weli ku socday in ka badan 32 km/saacaddii.
- Dusha qoyan ee heerkulku yahay +2°C, fogaanta joogsiga baabuurka ee taayirada xagaaga ayaa ka dheeraa 11 mitir ka baabuurka taayirka jiilaalka.
Sidoo kale eeg: Sidee loo kaydiyaa shidaalka?
Taayirada loo ogolaaday xilliga qaboobaha (calaamadaha barafka ee ka dhanka ah buuraha), i.e. taayirrada jiilaalka iyo taayirada wanaagsan ee xilli-xilliyeedka oo dhan - waxay sidoo kale si weyn u yareeyaan suurtagalnimada is-boodboodka. Ugu horreyntii, waxay leeyihiin xargo caag ah oo jilicsan oo aan adkeynayn marka heerkulka hoos u dhaco, iyo meelo badan oo xannibaadyo iyo jeexjeexyo. Goyn badan ayaa si fiican u xajin kara roobabka dayrta iyo xaaladaha barafka, kuwaas oo si gaar ah muhiim u ah roobka iyo barafku oo soo noqnoqda xilliga dayrta-jiilaalka. Ma aysan ahayn taayir jiilaal muddo dheer - taayirada jiilaalka casriga ah waa badbaado qabowga - marka heerkulku subaxdii uu ka hooseeyo 7-10 ° C.
