Conversely, the eastern areas remain comparatively dry.<\/li><li><strong>Supply of Humidity: <\/strong>The moisture content in the atmosphere is a crucial factor in determining rainfall patterns.

When these winds move from the sea to the continents, they bring about rainfall. However, when they move from land to sea, they create dry winds.<\/li><li><strong>Cold Air:<\/strong> Regions influenced by cold air currents tend to have lower humidity levels, resulting in reduced rainfall. Conversely, regions affected by warm air currents experience higher specific humidity and, consequently, heavier rainfall.<\/li><li><strong>Ocean Currents: <\/strong>Ocean currents, categorized as cold and warm, influence rainfall distribution.

Think of it like this: humidity is the potential for rain, while precipitation is the rain itself.<\/p>\n\n\n\n<ol class=\"wp-block-list\" start=\"2\"><li><strong>Q: What happens to humidity when it rains?<\/strong><\/li><\/ol>\n\n\n\n<p><strong>A:<\/strong> While heavy rain may initially seem to increase humidity, this isn&#8217;t always the case. Depending on the situation, rain can actually decrease or remain fairly consistent. When rain falls, it removes water vapor from the air, lowering humidity. However, if the rain evaporates back into the air shortly after falling, or if additional moisture evaporates from wet surfaces, humidity can rise again.<\/p>\n\n\n\n<ol class=\"wp-block-list\" start=\"3\"><li><strong>Q: Why does high humidity feel so uncomfortable?<\/strong><\/li><\/ol>\n\n\n\n<p><strong>A:<\/strong> High humidity reduces the rate of sweat evaporation from our skin, which plays a crucial role in regulating body temperature. When sweat can&#8217;t evaporate efficiently, we feel hotter and more uncomfortable. This is why humid days often feel much warmer than dry days at the same temperature.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"In_case_you_still_have_your_doubts_contact_us_on_9811333901\"><\/span><strong>In case you still have your doubts, contact us on 9811333901.<\/strong>&nbsp;<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>For UPSC Prelims Resources,&nbsp;<a href=\"https:\/\/edukemy.com\/upsc-cse-prelims-resource-centre\" target=\"_blank\" rel=\"noreferrer noopener\">Click here<\/a><\/p>\n\n\n\n<p>For Daily Updates and Study Material:<\/p>\n\n\n\n<p>Join our Telegram Channel &#8211;&nbsp;<a href=\"https:\/\/t.me\/WithEdukemy4IAS\" target=\"_blank\" rel=\"noreferrer noopener\">Edukemy for IAS<\/a><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>1.
