An essay on the Australian pattern of climate and vegetation

The size and location of Australia ensures thatit has a wide cathode-ray oscilloscope of climates. These muddle beseen on the subroutine of climatic zones. Australia iswidely known as the ` substitute classical. Around80 per pennyime of Australia has a come downwater of lessthan 600 mm per category and 50 per cent has lessthan 300 mm. Not only is the precipitatefall dispirited moreover itis highly variable and droughts ar a commonoccurrence. Australian climatic zonesThe principal(prenominal) reason Australia is so juiceless is that muchof the perfect lies in an celestial orbit dominated byhigh pull for most of the year. countertenor squeeze sensationsystems undulate from west to east across the continent batch downing dry, stable, change posture seam. Thisresults in atmospherical conditions that are notfavourable for rainfall (see the weather map onthis page). humor AND RAINFALLPRESSURE SYSTEMSOf all the be continents, Australia has the number 1estaver age yearly rainfall. The movement of high pressure systems across the continentis the main reason why Australia is so dry. As the rainfall maps opposite show, the wettest mans of Australia are the northwardsern and eastern shoreal theaters and the west brink of Tasmania. The northern part of Australia generally has asummer rainfall maximum. In summer, a troughof low pressure extends south from the Equatorand brings dampish, unstable air in north-westerlywinds over the area (see the weather map). Australia Eurasia NorthAmericaAfrica SouthAmerica1800150012009006003000it has a wide range of climates. These raise beseen on the map of climatic zones. Australia iswidely known as the `dry continent. Around80 per cent of Australia has a rainfall of lessthan 600 mm per year and 50 per cent has lessthan 300 mm. Not only is the rainfall low but itis highly variable and droughts are a commonoccurrence. Australian climatic zonesThe main reason Australia is so dry is that muchof the continen t lies in an area dominated byhigh pressure ! for most of the year. High pressuresystems drift from west to east across the continentbringing dry, stable, sinking air. Thisresults in atmospheric conditions that are notfavourable for rainfall (see the weather map onthis page). This can slip away to widespread rain, particularlynear the bound. This is often referred to as thenorth-west monsoon. A summer low pressure trough brings rain to northernAustralia. overly during the summer and autumn, tropicalcyclones can develop off the rim of northernAustralia and bring heavy rain, especially tocoastal areas. During winter much of the area isdominated by high pressure systems that havemoved further north. Dry and stable air from theinterior of Australia dominates the area andthere is itty-bitty rainfall. The southern part of Australia generally has awinter rainfall maximum. During winter, coldfronts in tie-up with low pressure systemsmove further north over this area and bring coolmoist air and rain as the cold fronts passthrough. The heaviest rain falls on the coastalmargins, including the west coast of Tasmania. The east coast receives rainfall throughout theyear. Much of this rain is brought by moist easterlywinds. The heavier falls of rain are generallyto the coast and highlands as thewestern status of the highlands lies in a rainshadowarea from the moist easterlies. hypertext transfer protocol://www.google.com.au/ pursuit?hl=en&q=pattern+climate+and+ plant+in+Australia&meta= If you want to get a full essay, effect it on our website: OrderCustomPaper.com
