What are the key advancements made by IMD in weather forecasting over the last decade?<\/strong><\/h3>\n<p>Over the last decade, IMD has improved forecast accuracy by 40%, increased Doppler weather radars to 39, and reduced weather model resolution to 12 km. This has enhanced prediction accuracy for severe weather events like heatwaves, thunderstorms, and cyclones.<\/p>\n<h3><strong>Q.2. How does Vision 2047 aim to transform IMD&#8217;s forecasting capabilities?<\/strong><\/h3>\n<p>Vision 2047 aims for zero-error forecasts for severe weather up to three days in advance, accuracy of 90% for five-day forecasts, and hyper-localised predictions with a resolution of 5-6 km at the village level.<\/p>\n<p><strong>Source:<\/strong><a href=\"https:\/\/indianexpress.com\/article\/explained\/explained-climate\/150-years-of-imd-what-the-weather-agency-has-planned-for-the-future-9783126\/\" target=\"_blank\" rel=\"nofollow noopener\">IE<\/a> | <a href=\"https:\/\/mausam.imd.gov.in\/responsive\/history.php\" target=\"_blank\" rel=\"nofollow noopener\">IMD<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Explore IMD&#8217;s journey of 150 years, highlighting advancements in forecasting accuracy, Vision 2047 for zero-error predictions, and Mission Mausam for weather management.<\/p>\n","protected":false},"author":5,"featured_media":44532,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[18],"tags":[],"class_list":{"0":"post-44531","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-mains-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/44531","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=44531"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/44531\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/44532"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=44531"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=44531"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=44531"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
