As this happens, a boundary\u00a0<strong>called the gust front<\/strong>\u00a0is created between the\u00a0<strong>rain-cooled air and warm-moist air on the surface.<\/strong><\/li>\n<li>This front pushes up the warm-moist air into the atmosphere, which forms new thunderstorms.<\/li>\n<li>These new thunderstorms produce more rain, thereby creating more rain-cooled air, which helps the gust front to maintain its strength.<\/li>\n<li>As this process keeps repeating itself, there comes a point when there is an inflow of air on the trailing side of the line of storms and bends it like an archer\u2019s bow.<\/li>\n<li>The cycle lasts as long as\u00a0<strong>new thunderstorms keep forming at the front<\/strong>, helping the system grow and move forward with strong winds.<\/li>\n<li>Bow echoes are not a new phenomenon. In 2022, a bow echo was formed\u00a0<strong>over Delhi and Noida<\/strong>. However, it was short-lived, lasting for an hour, and produced winds of up to 100 kmph.<\/li>\n<\/ul>\n<h2>Bow Echo FAQs<\/h2>\n<p><strong>Q1:<\/strong>\u00a0What is a decharo?<\/p>\n<p><strong>Ans:<\/strong>\u00a0A derecho (pronounced similar to &#8220;deh-REY-cho&#8221;) is a widespread, long-lived wind storm that is associated with a band of rapidly moving showers or thunderstorms<\/p>\n<p><strong>Q2:<\/strong>\u00a0What are the different types of bow echoes?<\/p>\n<p><strong>Ans:<\/strong>\u00a0Three primary initial modes of bow-echo formation are (i) weakly organized cells, (ii) squall lines, and (iii) supercells.<\/p>\n<p><strong>Source:<\/strong><a href=\"https:\/\/indianexpress.com\/article\/explained\/explained-climate\/bow-echo-delhi-storm-10031354\/\" target=\"_blank\" rel=\"nofollow noopener\">\u00a0\u00a0IE<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Bow Echo is essentially a line of storms, also called a squall line, on the radar that looks like a bow.
