These can change rapidly day by day, or even hour by hour.\n\nClimate, on the other hand, describes the long-term conditions of the atmosphere, typically averaged over a period of 30 years or more.\n\nTake Burkina Faso — the hottest country on Earth. Between 1960 and 1991, the average temperature was 83 °F (28 °C). That's the country’s climate: the average conditions over a period of time.

A baking hot day feels very different to one so cold you can see your breath. The temperature plays a crucial role in determining weather patterns and climatic zones across the Earth. It also influences humidity and the formation of pressure systems, which in turn drive wind and precipitation patterns.\n\nDifferences in temperature lead to the formation of pressure systems, which are a key driver of wind and precipitation patterns. High and low-pressure systems, created by differences in temperature, are responsible for the movement of air masses and the formation of weather fronts.\n\nExtreme temperatures can also lead to severe weather events, such as heat waves, cold snaps, and storms. These events can have significant impacts on human societies, causing damage to infrastructure, disrupting economic activities, and posing risks to human health and safety.\n\n![Graph](image://2aa9ffa1-e0a8-45cd-b164-78c0ea1adf85 \"An image of a town during a cold snap.

Relative humidity, a commonly used metric, quantifies the current amount of water vapor in the air relative to the maximum amount the air could hold at that temperature. \n\nThe primary factor affecting humidity is temperature. Warm air has a higher capacity to hold water vapor than cool air. Therefore, as temperature increases, so does the potential for higher humidity, assuming the amount of water vapor remains constant.\n\nThe **dew point** is the temperature at which air becomes saturated with water vapor.

These gradients are typically caused by differences in air temperature. For instance, when there is a large temperature difference over a short distance, a steep pressure gradient is created, leading to a rapid change in pressure.\n\nThe pressure gradient force is the primary force responsible for initiating wind. Isobars are the lines on a weather map joining places which share the same pressure. Pressure gradient force acts perpendicular to isobars, moving from areas of high pressure to areas of low pressure. The greater the pressure gradient, the stronger the force, and consequently, the stronger the wind.\n\n![Graph](image://c9dea336-bd42-4f03-b17c-0f7af488d18b \"An example of an Isobar map.

The higher the air rises, the cooler it becomes, and the more likely it is that clouds will form.\n\nSeveral factors can cause air to rise, leading to cloud formation. These include heating by the sun, which causes air to expand and rise, and the presence of hills and mountains, which force air upwards. Weather fronts, where warm and cold air meet, also cause air to rise. Other factors include convergence, where air flows into the same area from different directions, and turbulence, which can mix the air and lift it.\n\n![Graph](image://c234373c-da4c-4fe9-b5d1-b234d8b94803 \"The formation of clouds.

This can result in more frequent and intense weather events, such as storms and heat waves.\n\nDeforestation can impact local air masses by reducing evapotranspiration, a process by which water is transferred from the land to the atmosphere by evaporation from the soil and other surfaces and by transpiration from plants.\n\n![Graph](image://4e21c81a-5e6a-48e9-a431-3f2c25fb46f6 \"Deforestation caused by human activity.

This water barometer was unwieldy, more than 10 meters tall and towering over the roof of his house.\n\nThe strange device caused gossip among his neighbours and speculation he may be involved in witchcraft so he set about finding a more manageable alternative. Mercury is much denser than water, and by using mercury to measure air pressure he could create a device that was much smaller and more manageable than his initial water barometer.

Leonardo Da Vinci created a crude version of the hygrometer in 1480.\n\nHowever, the first modern hygrometer was invented by Swiss polymath Johann Heinrich Lambert in 1755, marking a significant advancement in meteorological observation. Today’s electronic hygrometers often use changes in electrical capacitance or resistance to gauge changes in humidity. Hygrometers play a crucial role in weather forecasting. They are particularly useful in predicting fog, dew, and precipitation, making them an indispensable tool in meteorology.","a4ebbabc-53bb-4a7c-b182-c42a1f13c83a",[1830],{"id":1831,"data":1832,"type":64,"version":24,"maxContentLevel":34},"55e28518-1100-439b-8525-7dc12044db4e",{"type":64,"reviewType":34,"spacingBehaviour":24,"multiChoiceQuestion":1833,"multiChoiceCorrect":1835,"multiChoiceIncorrect":1837,"multiChoiceMultiSelect":6,"multiChoiceRevealAnswerOption":6},[1834],"What is the purpose of a hygrometer?",[1836],"measure the amount of humidity in the atmosphere",[1838,1839,1840],"Predicting climate change","Measuring temperature","Gauging wind speed",{"id":1842,"data":1843,"type":24,"maxContentLevel":34,"version":24,"reviews":1846},"e4dbf532-004d-4927-8ce9-e7a4734839fd",{"type":24,"markdownContent":1844,"audioMediaId":1845},"An anemometer is a meteorological instrument used to measure wind speed and direction.

This marked the beginning of the development of anemometers, which have since become a common instrument in weather stations.\n\nSeveral versions have been developed since, including one devised by notable polymath Robert Hooke. Like many other meteorological instruments, the anemometer has developed through evolution and successive improvements. This has sometimes led to confusion about who deserves credit for the invention of the device.\n\nMost anemometers today have three or four cups, attached by horizontal arms to a central vertical rod. The wind blows, and as it does the cups spin round, spinning the central rod too. The number of spins is counted, and this can be used to calculate wind speed. Alternative versions of the anemometer include the hot-wire anemometer, which uses an electrically heated wire. Wind speed is calculated from how much power is needed to keep the wire at a constant temperature: the more power needed, the higher the wind speed.","72a1968c-217a-44e4-9b34-554857fe2287",[1847,1858,1874],{"id":1848,"data":1849,"type":64,"version":24,"maxContentLevel":34},"d9978701-7ddd-4c95-a233-bc3cd608fa5d",{"type":64,"reviewType":34,"spacingBehaviour":24,"multiChoiceQuestion":1850,"multiChoiceCorrect":1852,"multiChoiceIncorrect":1854,"multiChoiceMultiSelect":6,"multiChoiceRevealAnswerOption":6},[1851],"What is an anemometer used for?",[1853],"measure wind speed and direction",[1855,1856,1857],"Measure temperature","Measure humidity","Measure rainfall",{"id":1859,"data":1860,"type":64,"version":24,"maxContentLevel":34},"4eb6e461-a1b0-498f-8b2c-51ccf57cb518",{"type":64,"reviewType":229,"spacingBehaviour":24,"matchPairsQuestion":1861,"matchPairsPairs":1862,"matchPairsShowExamples":6},[89],[1863,1865,1868,1871],{"left":1864,"right":1040,"direction":34},"Barometer",{"left":1866,"right":1867,"direction":34},"Hygrometer","Measures humidity",{"left":1869,"right":1870,"direction":34},"Anemometer","Measures wind speed and direction",{"left":1872,"right":1873,"direction":34},"Radiosondes","Measuring devices carried by weather balloons",{"id":1875,"data":1876,"type":64,"version":24,"maxContentLevel":34},"5580881c-daf5-4efb-b3fa-31e6be286d3e",{"type":64,"reviewType":229,"spacingBehaviour":24,"matchPairsQuestion":1877,"matchPairsPairs":1878,"matchPairsShowExamples":6},[89],[1879,1882,1885,1888],{"left":1880,"right":1881,"direction":34},"1643","Evangelista Torricelli invented the first barometer",{"left":1883,"right":1884,"direction":34},"1714","Daniel Gabriel Fahrenheit invented the mercury thermometer",{"left":1886,"right":1887,"direction":34},"1755","Johann Heinrich Lambert invented the first modern hygrometer",{"left":1889,"right":1890,"direction":34},"1844","Lucien Vidi invented the aneroid barometer",{"id":1892,"data":1893,"type":25,"version":25,"maxContentLevel":34,"summaryPage":1895,"introPage":1903,"pages":1909},"79a0833f-f8a4-4c3c-9c6d-511a4ad79f17",{"type":25,"title":1894},"Advanced Meteorological Tools",{"id":1896,"data":1897,"type":34,"maxContentLevel":34,"version":24},"e501574c-55cd-4c7d-8e58-a2ffbbd1e934",{"type":34,"summary":1898},[1899,1900,1901,1902],"Weather balloons carry radiosondes to measure high-altitude atmospheric conditions","The first weather satellite, TIROS-1, launched in 1960, revolutionized weather observation","Weather radar detects precipitation and predicts severe weather like tornadoes","Weather stations collect data on temperature, humidity, pressure, and wind speed",{"id":1904,"data":1905,"type":27,"maxContentLevel":34,"version":24},"6ae6cfb1-66f2-4770-aa9c-d374d56b2f3f",{"type":27,"intro":1906},[1907,1908],"What significant discovery did Léon Teisserenc de Bort make using weather balloons?","How does a weather radar contribute to the accuracy of weather forecasts?",[1910,1929,1946,1962],{"id":1911,"data":1912,"type":24,"maxContentLevel":34,"version":25,"reviews":1915},"78d06aba-7e00-456e-ad60-fe99381c0ebb",{"type":24,"markdownContent":1913,"audioMediaId":1914},"A weather balloon, also known as a sounding balloon, is a high-altitude balloon that carries measuring devices called radiosondes into the sky.

When this funnel cloud touches the ground, it officially becomes a tornado.\n\nThere are several types of tornadoes, including landspouts, waterspouts, and multiple vortex tornadoes. The severity of these tornadoes is often rated on the Fujita scale or the Enhanced Fujita scale. These scales provide a standardized way to measure and compare the intensity of tornadoes, which is crucial for understanding their potential impact and for developing effective warning systems.","752138f6-2d35-43b2-8218-45ff0a63a9f7",[2006],{"id":2007,"data":2008,"type":64,"version":24,"maxContentLevel":34},"7531a111-e0ef-48cd-888c-11fbcb2b555f",{"type":64,"reviewType":34,"spacingBehaviour":24,"multiChoiceQuestion":2009,"multiChoiceCorrect":2011,"multiChoiceIncorrect":2013,"multiChoiceMultiSelect":6,"multiChoiceRevealAnswerOption":6},[2010],"How is the severity of tornadoes often rated?",[2012],"On the Fujita scale",[2014,2015,2016],"On the Richter scale","On the Beaufort scale","On the Saffir-Simpson scale",{"id":2018,"data":2019,"type":24,"maxContentLevel":34,"version":25,"reviews":2022},"191131ae-2503-40f1-9daa-86e655854a8b",{"type":24,"markdownContent":2020,"audioMediaId":2021},"A hurricane is a type of storm also known as a tropical cyclone, which forms over tropical or sub-tropical waters.

Understanding these stages is crucial for predicting the behavior and potential impact of these storms.\n\nThe mechanics of lightning and thunder are fascinating. Lightning, a powerful electrical discharge, produces light and heat, which in turn causes the surrounding air to expand rapidly and then contract, creating the sound we know as thunder. Lightning is also a significant hazard, killing more people each year than hurricanes or tornadoes. It can travel 10 - 12 miles (16 - 19 kilometers) from a thunderstorm, striking the ground with deadly force.\n\nThere are an estimated 16 million thunderstorms each year.

Ocean currents play a crucial role in regulating the Earth's climate by distributing heat around the globe.\n\nChanges in ocean currents due to climate change can have significant impacts on marine ecosystems and global weather patterns. For example, changes in ocean currents can alter the distribution of nutrients in the ocean, affecting the productivity of marine ecosystems. They can also influence weather patterns, potentially leading to more extreme weather events.\n\nClimate models suggest that climate change could weaken the Atlantic Meridional Overturning Circulation, a major ocean current system.
