Nem<\/p>\n
Yery\u00fcz\u00fcndeki su k\u00fctlelerinden buharla\u015fan su, atmosferin nemlenmesine yol a\u00e7ar. Atmosferdeki su buhar\u0131na hava nemlili\u011fi de denir. \u00d6nemli bir s\u0131cakl\u0131k etmeni olan atmosferdeki su buhar\u0131n\u0131n miktar\u0131, yere ve zamana g\u00f6re de\u011fi\u015fir. <\/p>\n

1) Buharla\u015fma: Atmosferdeki nemin kayna\u011f\u0131 yery\u00fcz\u00fcndeki su k\u00fctleleridir. S\u0131cakl\u0131k artt\u0131k\u00e7a, havadaki nem a\u00e7\u0131\u011f\u0131 artt\u0131k\u00e7a, su y\u00fczeyi geni\u015fledik\u00e7e, r\u00fczgar estik\u00e7e, bas\u0131n\u00e7 azald\u0131k\u00e7a, buharla\u015fma artar.<\/p>\n

3) Y\u00fckseklik: A\u011f\u0131r bir gaz olan su buhar\u0131, yer\u00e7ekiminin etkisiyle fazla y\u00fckselemez. Yo\u011funla\u015fma sonucu ya\u011f\u0131\u015f tekrar yery\u00fcz\u00fcne d\u00fc\u015fer.

4) Bas\u0131n\u00e7: Y\u00fcksek bas\u0131n\u00e7 alanlar\u0131nda al\u00e7al\u0131c\u0131 hava hareketi buharla\u015fmay\u0131 engeller. \u00c7\u00fcnk\u00fc al\u00e7alan havan\u0131n yo\u011funlu\u011funun artmas\u0131 su buhar\u0131n\u0131n y\u00fckselmesini \u00f6nler.

Mutlak nem, s\u0131cakl\u0131\u011fa ba\u011fl\u0131 olarak, Ekvator\u2019dan kutuplara do\u011fru, denizlerden karalara do\u011fru ve y\u00fckseklere \u00e7\u0131k\u0131ld\u0131k\u00e7a azal\u0131r.<\/p>\n

Hava k\u00fctleleri \u0131s\u0131nd\u0131k\u00e7a genle\u015fip hacimleri artar. Bu nedenle nem alma ve ta\u015f\u0131ma kapasiteleri de artar.

Bu nedenle hava k\u00fctlesinin doymas\u0131 i\u00e7in aradaki fark (13.08 gr) kadar nem y\u00fcklenmesi gerekir.<\/p>\n

Ba\u011f\u0131l Nem <\/p>\n
Hava her zaman ta\u015f\u0131yabilece\u011fi kadar nem y\u00fcklenmez. Genellikle havadaki su buhar\u0131 miktar\u0131yla doyma miktar\u0131 aras\u0131nda bir fark bulunur. Bu farka doyma a\u00e7\u0131\u011f\u0131 (nem a\u00e7\u0131\u011f\u0131) denir.<\/p>\n
