Kondenza\u010dn\u00ed stopy za letadly<\/strong><\/p>\n

Kondenza\u010dn\u00ed stopy za letadly (angl. condensation trails, zkr\u00e1cen\u011b \u00a0contrails<\/em>) jsou v\u00a0n\u011bkolika posledn\u00edch letech \u010dasto spojov\u00e1ny s\u00a0term\u00ednem \u201echemtrails\u201c (viz nap\u0159. \u010dl\u00e1nek na Technet – Blud: Tajn\u00e1 letadla pr\u00e1\u0161kuj\u00ed \u010cesko. Technet,\u00a0 (1<\/a>)<\/em>. Tyto nesmysln\u00e9 \u201eteorie\u201c jsou do zna\u010dn\u00e9 m\u00edry d\u016fsledkem neschopnosti n\u011bkter\u00fdch jedinc\u016f interpretovat jevy na obloze p\u0159irozenou cestou, s\u00a0n\u00e1sledn\u00fdm hled\u00e1n\u00edm alternativn\u00edch, \u010dasto \u00fasm\u011bvn\u00fdch vysv\u011btlen\u00ed. Jak tedy kondenza\u010dn\u00ed stopy vznikaj\u00ed, co v\u0161e m\u00e1 vliv na jejich vzhled na obloze?<\/p>\n

Kondenza\u010dn\u00ed stopa je p\u0159irozen\u00fdm jevem, d\u016fsledkem spalov\u00e1n\u00ed leteck\u00e9ho paliva dopravn\u00edmi letadly ve v\u00fd\u0161k\u00e1ch kolem 8 a\u017e 12 kilometr\u016f nad zemsk\u00fdm povrchem. P\u0159i spalov\u00e1n\u00ed leteck\u00e9ho benz\u00ednu se do okoln\u00ed atmosf\u00e9ry uvol\u0148uje velk\u00e9 mno\u017estv\u00ed vodn\u00ed p\u00e1ry a velmi drobn\u00fdch, mikroskopick\u00fdch pevn\u00fdch \u010d\u00e1ste\u010dek. Tyto drobn\u00e9 \u010d\u00e1ste\u010dky slou\u017e\u00ed jako tzv. kondenza\u010dn\u00ed j\u00e1dra, na nich\u017e kondenzuje vodn\u00ed p\u00e1ra, produkovan\u00e1 motory letadla. Ke kondenzaci doch\u00e1z\u00ed a\u017e v\u00a0ur\u010dit\u00e9 vzd\u00e1lenosti za motory letadla, po poklesu teploty spalovac\u00edch plyn\u016f na teplotu okoln\u00edho prost\u0159ed\u00ed (proto nevid\u00edme kondenza\u010dn\u00ed stopu ihned za letadlem, ale a\u017e kousek za n\u00edm).

Pokud dojde ke kondenzaci, z\u00e1le\u017e\u00ed dal\u0161\u00ed osud (a tedy vzhled) vznikl\u00e9 kondenza\u010dn\u00ed stopy na v\u00edce meteorologick\u00fdch faktorech \u2013 relativn\u00ed vlhkosti okoln\u00edho vzduchu, turbulenci a vertik\u00e1ln\u00edch pohybech okoln\u00ed atmosf\u00e9ry. Pokud je okoln\u00ed atmosf\u00e9ra relativn\u011b such\u00e1, mohou se vznikl\u00e9 kapi\u010dky velmi rychle vypa\u0159it, a kondenza\u010dn\u00ed stopa tak zanik\u00e1 pom\u011brn\u011b kr\u00e1tce po pr\u016fletu letadla.

Ty mohou d\u00e1le slou\u017eit jako krystaliza\u010dn\u00ed j\u00e1dra, na nich\u017e d\u00e1le krystalizuje vodn\u00ed p\u00e1ra z\u00a0jejich okol\u00ed. T\u00edm p\u00e1dem vznikaj\u00ed krystalky bl\u00edzk\u00e9 sv\u00fdm vzhledem krystalk\u016fm \u201enorm\u00e1ln\u00edch\u201c cir\u016f, od nich\u017e je prost\u00fdm okem ji\u017e nelze odli\u0161it.
