An essay on Weather maps

Weather lay discloses, or synoptic charts, croup appearrather complicated. plainly when you know what thelines and symbols slopped you will and these interpretseasy to use. One of the most of the essence(predicate) features of the atmosphereand one that is genuinely frequently sum of moneyd is commit drive, or the pitch of the standard atmosphere. All credit line hasweight. speckle we cant feel it because we ar constantlysurrounded by it, sensitive instrumentscalled barometers can measure the furrow blackjack. Atmospheric air pressure measurements aregiven in hectopascals (hPa). some(prenominal) times a day,air pressure is read at assorted weather stationsaround the world. Many observers around Australiameasure air pressure and other aspects ofthe weather and send them to the national andregional centres of the Bureau of Meteorology. These observations are feature with othersmade from satellites, aircraft, ships at sea and inother countries to prepare weather map s. The main(prenominal) lines that we search on weather mapsare called isobars. Isobars are lines joining placesof enough pressure. Highs and abjectsThe average weight of air at sea occupy is 1013 hPa. If air pressure measures more than 1013 hPa, it isusually an area of sinking air and is generally anarea of towering pressure. High pressure systems areoften called anticyclones. You can see from the plank foeman what a high pressure system lookslike and the left-handed electric charge the air travelsin a high pressure system. The despicable air, knownas wind, eternally carry ons step forward of a high and into a commencementpressure system. If air pressure measures below 1013 hPa, it isusually an area of rising air, and is generally anarea of low pressure. Low pressure systems areoften called cyclones. You can see in our dodge whata low pressure system looks like and the clockwisedirection the air travels in a low pressure system. Pressure systems generally bear upon from west toeast as they move across Austra! lia and around theworld. As they move they change in shape andoften change their latitudinal position. PRESSURE SYSTEMSSometimes people confuse pressure systems withair bargaines. An air mountain is a large section of theatmosphere containing air with a alike temperatureand moisture content. A line drawn on aweather map to show where two different airmasses meet is called a front. on that point are two maintypes of fronts: insensate fronts and warm fronts. When we look at the direction of winds on aweather map we can work out if temperatures arewarmer, cooler or about conventionality for the time ofyear. In Australia, a northerly wind (coming fromthe north) means warmer than modal(prenominal) temperaturesand a southeastwarderly wind, cooler than normaltemperatures. Easterlies and westerlies meantemperatures that are around normal. communication channel MASSES AND FRONTSWINDS AND TEMPERATURESAMPLE STUDYSnowfalls to the south and centralranges of south-eastern AustraliaThe weather map below for 30 July 2003 shows a stone-cold front moving into the Tasman Sea that hasbrought a `cold snap to south-eastern Australia. Cold and moist air from the ocean to the south ofAustralia locomote across Tasmania, Victoria andNew South Wales bringing large snowfalls tothe high parts of the tablelands and ranges. Over 40 centimetres of snow cut down in the SnowyMountains and therewere falls of up to20 centimetres overthe CentralTablelands.
