Latest News<\/h2>\n<p>Recently, over 20 people have died in the southern United States due to severe storms and tornado outbreaks affecting Missouri and Kentucky.<\/p>\n<h2>What is a Tornado?<\/h2>\n<ul>\n<li>A\u00a0<strong>tornado<\/strong>\u00a0is a\u00a0<strong>vertical, land-based column of violently rotating air<\/strong>\u00a0that forms from the base of a\u00a0<strong>thunderstorm to the ground<\/strong>.<\/li>\n<li>It is characterised by a\u00a0<strong>rapid cyclonic circulation<\/strong>\u00a0and is often seen as a\u00a0<strong>cloud-filled condensation funnel<\/strong>\u00a0extending from the sky to the ground.<\/li>\n<li>In cases of\u00a0<strong>low humidity<\/strong>, the tornado may not form a visible funnel and may appear only as a\u00a0<strong>swirl of dust or debris<\/strong>\u00a0near the ground.<\/li>\n<li>When such a rotating column of air forms over a\u00a0<strong>water body<\/strong>, it is known as a\u00a0<strong>waterspout<\/strong>.<\/li>\n<\/ul>\n<h3>Wind Speeds and Movement<\/h3>\n<ul>\n<li>Tornadoes typically exhibit\u00a0<strong>wind speeds ranging from 105 to 322 km\/h<\/strong>, but some extreme events can exceed this range.<\/li>\n<li>They can be\u00a0<strong>stationary<\/strong>\u00a0or\u00a0<strong>move at high speeds<\/strong>, often advancing at around\u00a0<strong>97 km\/h<\/strong>\u00a0across the landscape.<\/li>\n<li>The sheer speed and intensity of the winds make tornadoes\u00a0<strong>one of the most destructive natural phenomena<\/strong>\u00a0on land.<\/li>\n<\/ul>\n<h2>Mechanism of Formation<\/h2>\n<ul>\n<li>Tornado formation is closely linked to\u00a0<strong>interactions between contrasting air masses<\/strong>.<\/li>\n<li>A\u00a0<strong>collision of warm, moist air<\/strong>\u00a0(usually from tropical regions) with\u00a0<strong>cool, dry air<\/strong>\u00a0(typically from polar or upper regions), especially in the presence of a\u00a0<strong>low-pressure system or trough<\/strong>, leads to the formation of\u00a0<strong>thunderstorms<\/strong>\u00a0and may trigger tornadoes.<\/li>\n<li><strong>Cyclonic circulations<\/strong>\u00a0and\u00a0<strong>atmospheric instability<\/strong>\u00a0further contribute to the rotational dynamics needed for tornado development.<\/li>\n<li><strong>Geographical distribution:\u00a0<\/strong>Tornadoes occur most commonly in\u00a0<strong>mid-latitude regions<\/strong>\u00a0(between\u00a0<strong>20\u00b0 and 60\u00b0<\/strong>\u00a0latitude in both hemispheres) where\u00a0<strong>cold polar air meets warm tropical air<\/strong>, producing\u00a0<strong>frequent thunderstorm activity<\/strong>.\n<ul>\n<li>The\u00a0<strong>United States<\/strong>\u00a0experiences the highest frequency of tornadoes globally, particularly in the region known as\u00a0<strong>\u201cTornado Alley\u201d<\/strong>.<\/li>\n<li>Other countries prone to tornado occurrences include\u00a0<strong>Argentina<\/strong>\u00a0and\u00a0<strong>Bangladesh<\/strong>, which also lie in the\u00a0<strong>tropical-midlatitude interaction zones<\/strong>.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Measurement:\u00a0<\/strong>The\u00a0<strong>Enhanced Fujita Scale<\/strong>\u00a0is used to\u00a0<strong>classify the strength of tornadoes<\/strong>\u00a0based on\u00a0<strong>estimated wind speeds and associated damage levels<\/strong>.\n<ul>\n<li>The scale ranges from\u00a0<strong>EF0 (weakest)<\/strong>\u00a0to\u00a0<strong>EF5 (strongest)<\/strong>, with EF5 tornadoes being\u00a0<strong>catastrophically destructive<\/strong>, often flattening buildings and uprooting trees.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h2>Tornado FAQs<\/h2>\n<p><strong>Q1:\u00a0<\/strong>What is a tornado?<br \/>\n<strong>Ans:<\/strong>\u00a0A tornado is a rapidly rotating column of air extending from a thunderstorm to the ground, often forming a visible funnel-shaped cloud.<\/p>\n<p><strong>Q2:\u00a0<\/strong>In which region are tornadoes most common?<br \/>\n<strong>Ans:<\/strong>\u00a0Tornadoes are most frequent in the United States, especially in &#8220;Tornado Alley&#8221;, which includes states like Texas, Oklahoma, and Kansas.<\/p>\n<p><strong>Q3:\u00a0<\/strong>What scale is used to measure tornado intensity?<br \/>\n<strong>Ans:<\/strong>\u00a0Tornadoes are classified using the Enhanced Fujita (EF) scale, which ranges from EF0 to EF5 based on wind speed and damage caused.<\/p>\n<p><strong>Source:\u00a0<\/strong><a
