Inimelude p\u00e4\u00e4stmiseks on h\u00e4davajalik m\u00f5ista, kuidas need v\u00f5imsad tormid tekivad, ja ennustada, kuhu nad liiguvad.

Kuid Sentinel-satelliitidel on eriline v\u00f5ime, mis on veelgi parem. Need on varustatud k\u00f5rgtehnoloogiliste radarpildistusseadmetega, millega saab j\u00e4lgida merej\u00e4\u00e4 paksust, naftalekkeid ja isegi n\u00e4ha, kuidas maapind on muutunud p\u00e4rast maav\u00e4rinaid. Saksamaa Kosmoseagentuuri teadlased on v\u00e4lja t\u00f6\u00f6tanud uue radarpildistamise tehnika, mis v\u00f5imaldab Sentinel-satelliitidel n\u00e4ha l\u00e4bi orkaanide ja pildistada nende all olevat vett!<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1920\" data-credit=\"Contains modified Copernicus Sentinel data (2017), processed by ESA, CC BY-SA 3.0 IGO\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2017\/10\/Hurricanes_are_very_dangerous_especially_if_they_reach_land\" data-licence=\"CC BY-SA 3.0 IGO or ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2017\/10\/hurricanes_are_very_dangerous_especially_if_they_reach_land\/17867785-3-eng-GB\/Hurricanes_are_very_dangerous_especially_if_they_reach_land.jpg\" alt=\"Hurricanes are very dangerous, especially if they reach land\"><figcaption>Orkaanid on v\u00e4ga ohtlikud, eriti kui nad j\u00f5uavad maismaale<\/figcaption><\/figure>\n<p>Satelliite ei kavandatud orkaanide j\u00e4lgimiseks, seega on muljetavaldav, et teadlastel \u00f5nnestus leida selle tehnoloogia kasutamiseks uus viis.
