Mart 2026. doneo je snažne i međusobno povezane vremenske ekstreme u SAD: istorijske poplave na Havajima uz više od 1.300 mm kiše na pojedinim lokacijama, rekordne toplotne talase na zapadu sa temperaturama i do 109 °F (≈42,8 °C) i snažne oluje na istoku. Naučnici ukazuju na ulogu džet strima i planetarnih talasa, dok analize pokazuju da klimatske promene značajno povećavaju verovatnoću nekih ekstremnih događaja.
Haotični mart 2026: Poplave na Havajima, trocifrene temperature na zapadu i uloga džet strima
A deep freeze across the South, a spreading heat wave in the West and a trail of high winds and downpours leaving the East are in the forecast on March 17 after a weekend of bizarre weather across the country.On the heels of amajor storm that delivered downpours, high winds and thunderstormsalong the U.S. East Coast, the National Weather Service is predicting a "quieter" period of weather for many.

Mart 2026. zabeležio je izuzetno dinamično i kontrastno vreme širom SAD — od razarajućih poplava na Havajima i snežnih oluja na istoku do rekordnih, trocifrenih temperatura na zapadu. Ovi naizgled odvojeni događaji povezani su kroz velike atmosferske obrasce kao što su džet strim i planetarni talasi.
Glavni događaji meseca
Na Havajima su u martu nizovi kona low sistema doneli istorijske količine padavina i lokalne katastrofe. Neke lokacije su prijavile i do 54,92 inča (≈1.395 mm) kiše, što je dovelo do poplava, nestanka domova i hitnih evakuacija u severnim oblastima Oahua.
Istovremeno, zapadne savezne države iskusile su dugoćiveći toplotni talas pod uticajem postojanog visokog pritiska — došlo je do rušenja mesečnih temperaturnih rekorda u najmanje 11 saveznih država. U Yumi (Arizona) temperatura je dostigla 109 °F (≈42,8 °C), oko 28 °F (≈15,6 °C) iznad 30-godišnje normalne vrednosti.
Kako su ovi događaji povezani?
Naučnici ističu da su džet strim i planetarni talasi ključni prenosioci uticaja između regiona. Kada džet strim uspori i postane vijugav, obrazci se pojačavaju — isti sistemi mogu dugo ostati nad određenim oblastima, donoseći ponavljajuće kona low, atmosferske reke u Pacifičkom severozapadu, ili produžene talase vrućine na zapadu.
«Obrasci se hrane jedni drugim i pokreću vreme preko kontinenta», rekao je Daniel McEvoy iz Western Regional Climate Center.
Detalji o padavinama i šteti na Havajima
Preliminarni podaci Nacionalne meteorološke službe pokazuju ekstremne količine: do 52 inča (≈1.321 mm) na Oahuu, 54,92 inča (≈1.395 mm) na Summitu na Mauiju i 42,2 inča (≈1.072 mm) na Puu Waawaa na ostrvu Havaji. Poplave su odnele domove i natkrile naselja poput Waialue; zbog opasnosti od kvara brane Wahiawa, više hiljada ljudi je evakuisano.
Toplotni talas na zapadu
Stalni visok pritisak sprečio je padavine i omogućio je višenedeljne trocifrene temperature. Po državnim beleškama, 492 lokacije su zabeležile novi mesečni maksimum, najmanje 300 su imale najtopliju mesečnu noć, dok je više od 1.000 dnevnih rekorda za maksimalne temperature ili tople noćne vrednosti takođe oboreno.
Ekstremi i klimatski kontekst
Naučnici povezuju povećanu učestalost i intenzitet nekih ovih događaja sa klimatskim promenama. Organizacija World Weather Attribution zaključila je da bi retki zapadni toplotni talas bio «virtuelno nemoguć» bez ljudski izazvanog zagrevanja; u deceniji pre analize, verovatnoća takvog događaja porasla je oko četiri puta.
Stručnjaci upozoravaju da klimatske promene menjaju raspodelu ekstremnih događaja i povećavaju verovatnoću i intenzitet toplih talasa. Istovremeno, nagle temperaturne oscilacije (»whiplash«) i dalje zbunjuju javnost, jer su mnogi građani navikli na blaže zime.
Zaključak
Mart 2026. pokazao je kako globalna i regionalna atmosferska dinamika može proizvesti ekstremne, međusobno povezane vremenske događaje. Dok meteorolozi nastavljaju da proučavaju okidače i povratne veze, sve veći uticaj ljudskog zagrevanja na verovatnoću i intenzitet ovakvih događaja postaje sve jasniji.
