Daily Weather in Caberra
I will be observing Australia's weather in a 3-day period. It will be from March 19-21. The forecasted high for my first day is 72ºF and the forecasted low is 47ºF. The precipitation percentage on this day is 0%. The forecasted high for my second day is 70ºF and the forecasted low is 48ºF. The precipitation percentage on this day is 0%. the forecasted high for my third day is 74ºF and the forecasted low is 48ºF. The precipitation percentage is 10%. The average pressure during the three way period was 30.05. The pressure increased over the three day period. The average wind speed over the five day period was 7 MPH.
The above diagram shows Canberra's radar. Since Australia is a desert, there are barely any clouds as you can see. Although there are clouds above the mountains, they are cold clouds. There is no precipitation whatsoever in the city of Canberra. It looks like they are having clear skies today. It should be great weather to go out and have fun. There are however clouds on the mountains that are green, which shows that there will be light to no rain over the mountains. The type of surface is pretty much a city and a few mountains, or land desert. There is a lake west of the mountain.
The area of Canberra is shown above. They are currently experiencing a cold front that is headed and located East of the country. It is a low pressure area, about 1000mb. Pressure decreases as you move South. Also to the south of Australia, there is a warm front. That location has a very low pressure.
Above photo shows the entire Australia. North of Australia is covered with low pressure system while south has both high and low pressures. Average pressure is about 1012mb. A cold front is located East of the country and will also be heading East. Highest pressure is located in the Southwest with 1024mb and low pressure system is in the Southeast with about 892mb.

Global and Local Winds in Australia
The winds in Australia is very similar to the winds found in the state of Hawaii. The latitude and longitude of 35.3080ºS, 149.1245ºE. Unlike the United States, Australia is located in the Southern Hemisphere. Being in the Southern Hemisphere, the seasons are opposite lol. Australia is located in the Hadley Cell. Australia being in the Souther Hemisphere, its planetary wind belt is is the Mid-Latitude Westerlies. The wind in Australia blows from West to East, just like the rest of the world. No place on the East coast of Australia have prevailing wind, as they change with pressure systems. Australia is dominate by a belt of the high pressure system around the earth. Australia is not located near any special location. Though it is in the subtropical highs.
Australia is the driest continent on Earth. The geological features that influence the climate of Australia most strongly is the absence of sufficiently high mountain ranges west of the Great Dividing Range running north-south near the coast of the continent. Australia is dominated by the belt of high pressure around the Earth, composed of series of high pressure systems that move from west to east near the latitude of 30ºS. In summer, these high pressure systems cover the southern parts of the continent and by winter, they have moved north to the central regions. For this being, Australia experiences mostly clear skies, the descending air being dry. Westerly winds is located immediately to the south of the high pressure zone. Fronts and depressions in this band of westerly winds are areas where the air pressures are locally lower. The southeast trade winds occur immediately to the north of the high pressure belt. These winds converge with the northeast trades of the Northern Hemisphere to form the inter-tropical convergence zone, a belt where the rising warm air containing large amounts of moisture. During the summer, there is a low pressure that remains continuously over northern Australia, the monsoon season that is hot and wet.
The absence of mountains in Australia causes the winds to blow the country's moisture away. The five types of breezes associated with mountains are country breeze, desert winds, chinook winds, katabatic winds and Santa Ana winds. The wind or breeze that Australia experiences most is the country winds. This is due to the lack of mountains. Also happens but very rarely is the desert winds. This is because there are many deserts in Australia but rarely create haboobs. There are 8 coastlines in Australia. The two breezes that are associated with coastlines are sea breeze and land breeze. Australia experiences sea breezes on the East side of the country.
