Reinforced to withstand a gas explosion, it&#8217;s the base for Norman\u2019s daily weather balloon launch. Yes, balloons \u2014 one of the oldest forecasting tools reliably capturing weather warnings today.<\/p>\n<p>Every day at 0 Z and 12 Z (6 a.m. and 6 p.m. CST) over 700 locations worldwide release a weather balloon. \u201cIt\u2019s a picture of the atmosphere around the world at a given hour,\u201d says Forrest Mitchell, the observations program leader for the National Weather Service in Norman. A weather balloon is a helium-filled vehicle that lifts a radiosonde, an instrument that takes atmospheric measurements every second, to 100,000 feet above Earth\u2019s surface.<\/p>\n<p>While the process of launching a balloon hasn\u2019t changed since 1938, the instrument technology keeps progressing. Through its antenna, the radiosonde sends the data it collects back to the National Weather Service headquarters in Silver Springs, Maryland \u2014 between six and 7,000 readings. Computers crunch the data into figures on wind speed and direction, temperature, humidity and atmospheric pressure. These combined measurements provide a baseline for weather models and forecasts for severe weather over the next 12 hours.<\/p>\n<p>Weather balloon operators Forrest Mitchell and Daryl Williams have been launching balloons for almost three decades. \u201cSo we\u2019re starting to get the hang of it,\u201d Mitchell jokes. On a windy evening at the beginning of May, Mitchell and Williams explained the process of launching a balloon.<\/p>\n<figure id=\"attachment_71005\" aria-describedby=\"caption-attachment-71005\" style=\"width: 474px\" class=\"wp-caption alignnone\"><img fetchpriority=\"high\" decoding=\"async\" class=\"size-large wp-image-71005\" src=\"http:\/\/news.medill.northwestern.edu\/chicago\/wp-content\/uploads\/sites\/3\/2018\/05\/DSC_9097-1024x684.jpg\" alt=\"\" width=\"474\" height=\"317\" srcset=\"https:\/\/news.medill.northwestern.edu\/chicago\/wp-content\/uploads\/sites\/3\/2018\/05\/DSC_9097-1024x684.jpg 1024w, https:\/\/news.medill.northwestern.edu\/chicago\/wp-content\/uploads\/sites\/3\/2018\/05\/DSC_9097-300x200.jpg 300w, https:\/\/news.medill.northwestern.edu\/chicago\/wp-content\/uploads\/sites\/3\/2018\/05\/DSC_9097-768x513.jpg 768w, https:\/\/news.medill.northwestern.edu\/chicago\/wp-content\/uploads\/sites\/3\/2018\/05\/DSC_9097.jpg 1200w\" sizes=\"(max-width: 474px) 100vw, 474px\" \/><figcaption id=\"caption-attachment-71005\" class=\"wp-caption-text\">While the weather balloon inflates, Forrest Mitchell explains that operators inflate the balloons to rise about 985 feet per minute.
