In general the effect of the latitude on temperature is well pronounced on the map as the isotherms are generally parallel to the latitude. The\u00a0<strong>deviation from this general trend is more pronounced in January than in July, especially in the northern hemisphere<\/strong>. In the\u00a0<strong>northern hemisphere the land surface area is much larger than in the southern hemisphere<\/strong>. Hence, the effects of land mass and the ocean currents are well pronounced.<\/li>\n\n\n\n<li><strong>In January the isotherms deviate to the north over the ocean and to the south over the continent.\u00a0<\/strong>This can be seen on the North Atlantic Ocean. The\u00a0<strong>presence of warm ocean currents, Gulf Stream and North Atlantic drift, make the Northern Atlantic Ocean warmer and the isotherms bend towards the north<\/strong>. Over the land the temperature decreases sharply and the isotherms bend towards south in Europe. It is much pronounced in the Siberian plain.<\/li>\n\n\n\n<li>The mean January temperature along 60\u00b0 E longitude is minus 20\u00b0 C both at 80\u00b0 N and 50\u00b0 N latitudes. The mean monthly temperature for January is over 27\u00b0 C, in equatorial oceans over 24\u00b0 C in the tropics and 2\u00b0 C \u2013 0\u00b0 C in the middle latitudes and \u201318\u00b0 C to \u201348\u00b0 C in the Eurasian continental interior.<\/li>\n\n\n\n<li>The\u00a0<strong>effect of the ocean is well pronounced in the southern hemisphere<\/strong>. Here the isotherms are\u00a0<strong>more or less parallel to the latitudes<\/strong>\u00a0and the variation in temperature is more gradual than in the northern hemisphere. The isotherm of 20\u00b0 C, 10\u00b0 C, and 0\u00b0 C runs parallel to 35\u00b0S, 45\u00b0 S and 60\u00b0 S latitudes respectively.<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter is-resized\"><img decoding=\"async\" src=\"https:\/\/lotusarise.com\/wp-content\/uploads\/2024\/10\/Isotherm-january.webp\" alt=\"Isotherm january\" class=\"wp-image-51261\" style=\"width:786px;height:auto\" title=\"UPSC Prelims Research: Geography 2024 1\"\/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Select the answer using the code given below: Answer:(a) 1 only Notes:<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":"","footnotes":""},"categories":[1,3],"tags":[37],"years":[49],"class_list":["post-2384","post","type-post","status-publish","format-standard","hentry","category-upsc","category-prelims","tag-geography","years-49"],"acf":[],"taxonomy_info":{"category":[{"value":1,"label":"UPSC"},{"value":3,"label":"Prelims"}],"post_tag":[{"value":37,"label":"Geography"}],"years":[{"value":49,"label":"2024"}]},"featured_image_src_large":false,"author_info":{"display_name":"LotusArise","author_link":"https:\/\/lotusarise.com\/qna\/author\/team-lotusarise"},"comment_info":0,"category_info":[{"term_id":1,"name":"UPSC","slug":"upsc","term_group":0,"term_taxonomy_id":1,"taxonomy":"category","description":"","parent":0,"count":1269,"filter":"raw","cat_ID":1,"category_count":1269,"category_description":"","cat_name":"UPSC","category_nicename":"upsc","category_parent":0},{"term_id":3,"name":"Prelims","slug":"prelims","term_group":0,"term_taxonomy_id":3,"taxonomy":"category","description":"","parent":1,"count":1251,"filter":"raw","cat_ID":3,"category_count":1251,"category_description":"","cat_name":"Prelims","category_nicename":"prelims","category_parent":1}],"tag_info":[{"term_id":37,"name":"Geography","slug":"geography","term_group":0,"term_taxonomy_id":37,"taxonomy":"post_tag","description":"","parent":0,"count":167,"filter":"raw"}],"_links":{"self":[{"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/posts\/2384","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/comments?post=2384"}],"version-history":[{"count":0,"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/posts\/2384\/revisions"}],"wp:attachment":[{"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/media?parent=2384"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/categories?post=2384"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/tags?post=2384"},{"taxonomy":"years","embeddable":true,"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/years?post=2384"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
