ENSO is series of linked weather- and ocean-related phenomena.\u00a0<\/li>\n<li>La Ni\u00f1a events are indicated by sea-surface temperature decreases of more than 0.5 degrees Celsius (0.9 degrees Fahrenheit) for at least five successive three-month seasons.<\/li>\n<\/ul>\n<h3>La Nina Causes<\/h3>\n<ul>\n<li>La Ni\u00f1a is caused by a build-up of <strong>cooler-than-normal waters<\/strong> in the tropical Pacific, the area of the Pacific Ocean between the Tropic of Cancer and the Tropic of Capricorn.\u00a0<\/li>\n<li>Unusually strong, eastward-moving trade winds and ocean currents bring this cold water to the surface, a process known as upwelling. Upwelling can cause a drastic drop in sea-surface temperature.<\/li>\n<\/ul>\n<h3>La Nina Effects<\/h3>\n<ul>\n<li><strong>Impact on Air Pressure and Rainfall: <\/strong>La Ni\u00f1a lowers air pressure over the western Pacific, leading to increased rainfall. Southeast Asia experiences stronger summer monsoons, benefiting agriculture in northwest India and Bangladesh.<\/li>\n<li><strong>Risk of Flooding in Australia:<\/strong> While La Ni\u00f1a supports agriculture in South Asia, strong events can cause severe flooding in northern Australia due to excessive rainfall and low-pressure systems.<\/li>\n<li><strong>Global Rainfall Patterns: <\/strong>La Ni\u00f1a brings more rain to southeastern Africa and northern Brazil. In contrast, it increases air pressure over the central and eastern Pacific, causing dry conditions.<\/li>\n<li><strong>Drier Conditions in Some Regions: <\/strong>Regions like the west coast of tropical South America, the Gulf Coast of the US, and the pampas of South America experience reduced rainfall and dry spells during La Ni\u00f1a.<\/li>\n<li><strong>Boost to the Fishing Industry: <\/strong>Upwelling caused by La Ni\u00f1a brings cold, nutrient-rich waters to the surface, supporting plankton growth. This benefits fish populations and predators like sea bass.<\/li>\n<li><strong>Duration and Seasonal Peak:<\/strong> La Ni\u00f1a events usually last between one and three years, whereas El Ni\u00f1o typically lasts less than a year. Both tend to peak during the Northern Hemisphere winter.<\/li>\n<\/ul>\n<h2>La Nina FAQs<\/h2>\n<p><strong>Q1. <\/strong>What is the meaning of La Ni\u00f1a?<\/p>\n<p><strong>Ans. <\/strong>La Ni\u00f1a is a climate pattern causing cooler-than-normal sea-surface temperatures in the tropical Pacific, affecting global weather patterns.<\/p>\n<p><strong>Q2<\/strong> How does La Ni\u00f1a affect India?<\/p>\n<p><strong>Ans. <\/strong>La Ni\u00f1a strengthens the Indian monsoon, increasing rainfall in northwest India and Bangladesh, benefiting agriculture but sometimes causing floods.<\/p>\n<p><strong>Q3. <\/strong>What is the difference between La Ni\u00f1a and El Ni\u00f1o?<\/p>\n<p><strong>Ans. <\/strong>La Ni\u00f1a causes cooler Pacific waters and increased rainfall, while El Ni\u00f1o causes warmer waters and disrupts global weather patterns.<\/p>\n<p><strong>Q4. <\/strong>What is worse, El Ni\u00f1o or La Ni\u00f1a?<\/p>\n<p><strong>Ans. <\/strong>El Ni\u00f1o generally causes more severe global weather disruptions, but La Ni\u00f1a can lead to destructive floods in certain regions.<\/p>\n<p><strong>Source: <\/strong><a href=\"https:\/\/economictimes.indiatimes.com\/news\/india\/climate-change-more-robust-now-la-nina-may-not-be-effective-in-warmer-future-scientists\/articleshow\/118815326.cms?from=mdr\" target=\"_blank\" rel=\"nofollow noopener\">ET<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>La Ni\u00f1a is marked by unusually cold ocean temperatures in the Equatorial Pacific, while El Ni\u00f1o features unusually warm ocean temperatures<\/p>\n","protected":false},"author":5,"featured_media":31209,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-31208","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/31208","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=31208"}],"version-history":[{"count":1,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/31208\/revisions"}],"predecessor-version":[{"id":93825,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/31208\/revisions\/93825"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/31209"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=31208"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=31208"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=31208"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
