In What Ways Do Tornadoes Affect Local Economies?

???impact.descriptions.impactdescription???

A tornado is a violently rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. The windstorm is often referred to as a twister, whirlwind or cyclone, although the word cyclone is used in meteorology to name a weather system with a low-pressure area in the center around which, from an observer looking down toward the surface of the earth, winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern. Tornadoes come in many shapes and sizes, and they are often visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it. Most tornadoes have wind speeds less than 110 miles per hour (180 km/h), are about 250 feet (80 m) across, and travel a few miles (several kilometers) before dissipating. The most extreme tornadoes can attain wind speeds of more than 300 miles per hour (480 km/h), are more than two miles (3 km) in diameter, and stay on the ground for dozens of miles (more than 100 km).Various types of tornadoes include the multiple vortex tornado, landspout, and waterspout. Waterspouts are characterized by a spiraling funnel-shaped wind current, connecting to a large cumulus or cumulonimbus cloud. They are generally classified as non-supercellular tornadoes that develop over bodies of water, but there is disagreement over whether to classify them as true tornadoes. These spiraling columns of air frequently develop in tropical areas close to the equator and are less common at high latitudes. Other tornado-like phenomena that exist in nature include the gustnado, dust devil, fire whirl, and steam devil. Tornadoes occur most frequently in North America (particularly in central and southeastern regions of the United States colloquially known as tornado alley; the USA and Canada have by far the most tornadoes of any countries in the world), South Africa, much of Europe (except Spain, most of the Alps, Balkans, and northern Scandinavia), western and eastern Australia, New Zealand, Bangladesh and adjacent eastern India, Japan, Philippines, and southeastern South America (Uruguay and Argentina). Tornadoes can be detected before or as they occur through the use of Pulse-Doppler radar by recognizing patterns in velocity and reflectivity data, such as hook echoes or debris balls, as well as through the efforts of storm spotters. Affect may refer to: Affect (education) Affect (linguistics), attitude or emotion that a speaker brings to an utterance Affect (philosophy) Affect (psychology), the experience of feeling or emotion Affect display, signs of emotion, such as facial expression, vocalization, and posture Affect theory Affective science, the scientific study of emotion Affective computing, an area of research in computer science aiming to understand the emotional state of users Reduced affect display, a.k.a. emotional blunting or affective flattening, a reduction in emotional reactivity Pseudobulbar affect, a.k.a. labile affect, the unstable display of emotion Affect (rhetoric), the responsive, emotional feeling that precedes cognition Affected accent; see Accent (sociolinguistics) Affect (company), a defunct Japanese video game developerAn economy (from Ancient Greek οἰκονομία (oikonomía) 'management of a household, administration'; from οἶκος (oîkos) 'household', and νέμω (némō) 'distribute, allocate') is an area of the production, distribution and trade, as well as consumption of goods and services by different agents. In general, it is defined 'as a social domain that emphasize the practices, discourses, and material expressions associated with the production, use, and management of resources'. A given economy is a set of processes that involves its culture, values, education, technological evolution, history, social organization, political structure and legal systems, as well as its geography, natural resource endowment, and ecology, as main factors. These factors give context, content, and set the conditions and parameters in which an economy functions. In other words, the economic domain is a social domain of interrelated human practices and transactions that does not stand alone. Economic agents can be individuals, businesses, organizations, or governments. Economic transactions occur when two groups or parties agree to the value or price of the transacted good or service, commonly expressed in a certain currency. However, monetary transactions only account for a small part of the economic domain. Economic activity is spurred by production which uses natural resources, labor and capital. It has changed over time due to technology, innovation (new products, services, processes, expanding markets, diversification of markets, niche markets, increases revenue functions) such as, that which produces intellectual property and changes in industrial relations (most notably child labor being replaced in some parts of the world with universal access to education). A market-based economy is one where goods and services are produced and exchanged according to demand and supply between participants (economic agents) by barter or a medium of exchange with a credit or debit value accepted within the network, such as a unit of currency. A command-based economy is one where political agents directly control what is produced and how it is sold and distributed. A green economy is low-carbon, resource efficient and socially inclusive. In a green economy, growth in income and employment is driven by public and private investments that reduce carbon emissions and pollution, enhance energy and resource efficiency, and prevent the loss of biodiversity and ecosystem services. A gig economy is one in which short-term jobs are assigned or chosen via online platforms. New economy is a term that referred to the whole emerging ecosystem where new standards and practices were introduced, usually as a result of technological innovations. The global economy refers to humanity's economic system or systems overall.
