A M\u00e1sf\u00e9lfok – \u00c9ghajlatv\u00e1ltoz\u00e1s k\u00f6z\u00e9rthet\u0151en oldalon a meteorol\u00f3gus ismerteti: term\u00e9szetes folyamat, hogy a S\u00e1ndor, J\u00f3zsef \u00e9s Benedek n\u00e9vnapok k\u00f6rny\u00e9k\u00e9n melegszik az id\u0151, hiszen ekkorra tehet\u0151 a tavaszi nap\u00e9jegyenl\u0151s\u00e9g, azaz a csillag\u00e1szati tavasz kezdete. A kor\u00e1bbi \u00e9vtizedekben m\u00e9g 80-100 sz\u00e1zal\u00e9kos biztons\u00e1ggal igaz n\u00e9pi b\u00f6lcsess\u00e9g, az ezredfordul\u00f3 \u00f3ta viszont m\u00e1r j\u00f3val kisebb, 50-70 sz\u00e1zal\u00e9kos ar\u00e1nyban v\u00e1lt be. A m\u00e1rcius k\u00f6zepi felmeleged\u00e9s az\u00e9rt is volt kisebb m\u00e9rt\u00e9k\u0171 az ut\u00f3bbi \u00e9vtizedben, mivel m\u00e1rcius elej\u00e9n m\u00e1r eleve melegebb volt a kor\u00e1bbi \u00e9vekben megszokotthoz k\u00e9pest. A tavaszkezdet eltol\u00f3d\u00e1s\u00e1val a h\u00f3nap v\u00e9gi h\u0151m\u00e9rs\u00e9kletek pedig m\u00e1r csak kisebb m\u00e9rt\u00e9kben emelkedtek.<\/p>\n
Mint kifejtette: a m\u00e1rciusi \u00e1tlagh\u0151m\u00e9rs\u00e9klet 2011-2019-ben m\u00e1r megk\u00f6zel\u00edtette a 7 Celsius-fokot, m\u00edg a kor\u00e1bbi \u00e9vtizedekben 5-6 fok volt jellemz\u0151. A h\u00f3nap sor\u00e1n jellemz\u0151en h\u00e1rom fagypont alatti \u00e1tlagh\u0151m\u00e9rs\u00e9klet\u0171 nap jelentkezik orsz\u00e1gos \u00e1tlagban, ez nem v\u00e1ltozott sz\u00e1mottev\u0151en a vizsg\u00e1lt 49 \u00e9vben. Azonban a 10 fok feletti k\u00f6z\u00e9ph\u0151m\u00e9rs\u00e9klet\u0171 napok sz\u00e1ma a kor\u00e1bbi \u00e9vtizedekben jellemz\u0151 2-5-r\u0151l 7-re n\u00f6vekedett. Az \u00e1ltal\u00e1nos meleged\u00e9s mellett az egyes \u00e9vek k\u00f6z\u00f6tti v\u00e1ltoz\u00e9konys\u00e1g \u00e9s a h\u00f3napon bel\u00fcli sz\u00e9ls\u0151s\u00e9gek megmaradtak. 2020 m\u00e1rciusa a hatodik legmelegebb volt 1979 \u00f3ta Eur\u00f3p\u00e1ban: k\u00f6zel 2 fokkal volt magasabb az 1981-2010-es id\u0151szak \u00e1tlag\u00e1hoz k\u00e9pest.<\/p>\n
Kis Anna kit\u00e9rt arra is, hogy az elm\u00falt harminc \u00e9vben egy\u00e9rtelm\u0171en cs\u00f6kkent a fagyos, azaz az olyan napok sz\u00e1ma, amikor a minimumh\u0151m\u00e9rs\u00e9klet 0 fok al\u00e1 cs\u00f6kkent. Az \u00e1ltal\u00e1nosan meleged\u0151 tendencia ellen\u00e9re a hideggel kapcsolatos h\u0151m\u00e9rs\u00e9kleti indexek elemz\u00e9se is al\u00e1t\u00e1masztja, hogy az \u00e9ghajlatv\u00e1ltoz\u00e1s nemcsak egyszer\u0171en magasabb \u00e1tlagh\u0151m\u00e9rs\u00e9kletekkel j\u00e1r, hanem a h\u0151m\u00e9rs\u00e9kleti sz\u00e9ls\u0151s\u00e9gek megv\u00e1ltoz\u00e1s\u00e1val is.<\/p>\n
Felh\u00edvta a figyelmet ugyanakkor, hogy a szezon\u00e1lis ciklus egy apr\u00f3 v\u00e1ltoz\u00e1sa is komolyabb k\u00e1rokat okozhat a term\u00e9szetben. A mez\u0151gazdas\u00e1gi \u00e9s az otthoni, kerti munk\u00e1latok egy r\u00e9sze is m\u00e1rciusban kezd\u0151dik, amelyeket alapvet\u0151en ink\u00e1bb az id\u0151j\u00e1r\u00e1si k\u00f6r\u00fclm\u00e9nyekhez, mintsem konkr\u00e9t d\u00e1tumokhoz igaz\u00edtanak. Azonban \u00edgy is gyakran probl\u00e9m\u00e1t okoz a tavaszi fagyk\u00e1r – ez id\u00e9n is fenyegeti a mez\u0151gazdas\u00e1gi termel\u00e9st Magyarorsz\u00e1gon – tette hozz\u00e1. Az \u00e9vszakok kezdet\u00e9nek eltol\u00f3d\u00e1sa a n\u00f6v\u00e9nyek \u00e9letciklus\u00e1t is befoly\u00e1solja. Ez pedig az \u00e9vezredek alatt \u00f6sszecsiszol\u00f3dott \u00f6kosziszt\u00e9ma-kapcsolatok sz\u00e9tcs\u00fasz\u00e1s\u00e1hoz vezethet. Ha p\u00e9ld\u00e1ul bizonyos n\u00f6v\u00e9nyek nem akkor vir\u00e1goznak, amikor a rovaroknak arra sz\u00fcks\u00e9ge lenne, az h\u00e1tr\u00e1nyosan \u00e9rintheti az \u00e1llatok \u00e9letciklus\u00e1t \u00e9s a beporz\u00e1st – \u00edrta Kis Anna meteorol\u00f3gus.
