Numera \u00e4r det enkelt att ta reda p\u00e5 genom att titta p\u00e5 satellitbilder p\u00e5 TV eller p\u00e5 internet.<\/p>\n<\/div>\n<p>F\u00f6r bara n\u00e5gra decennier sedan var v\u00e4derprognoserna betydligt mer os\u00e4kra. Ett av problemen var att v\u00e4derstationer endast fanns p\u00e5 ett f\u00e5tal platser. \u00d6vriga platser var v\u00e4derf\u00f6rh\u00e5llandena n\u00e4stan ett mysterium.<\/p>\n<p>Idag t\u00e4cker satelliterna hela jordklotet. Varje molnsystem och varje storm kan observeras medan de bildas och f\u00f6r\u00e4ndras.<\/p>\n<p>Den f\u00f6rsta v\u00e4dersatelliten, TIROS (Television and InfraRed Observation Satellite), sk\u00f6ts upp den 1 april 1960. Den var utrustad med tv\u00e5 TV-kameror som s\u00e4nde gryniga bilder tillbaka till jordytan.<\/p>\n<p>Dagens v\u00e4dersatelliter \u00e4r st\u00f6rre och betydligt mer avancerade. De f\u00f6rser meteorologerna med extremt detaljerade bilder och annan anv\u00e4ndbar information om atmosf\u00e4ren och haven, vilket hj\u00e4lper dem att f\u00f6rfina sina prognoser. Vissa v\u00e4dersatelliter sv\u00e4var alltid \u00f6ver samma del av jordytan. De befinner sig i geostation\u00e4ra banor, 36 000 km ovanf\u00f6r ekvatorn.<\/p>\n<p>Andra kretsar runt jorden fr\u00e5n nordpolen till sydpolen och tillbaka. De r\u00f6r sig mycket n\u00e4rmare jordytan (vissa s\u00e5 l\u00e5gt som 800 km) och levererar mycket detaljerade n\u00e4rbilder av v\u00e4dersystem \u00f6ver hela v\u00e4rlden.<\/p>","protected":false},"excerpt":{"rendered":"<p>Do you want to know whether it will rain on your picnic or be sunny for your day trip?
