The causes of different weather is the entire atmosphere surrounding earth is in constant motion caused by the uneven heating effect of the sun due to the spin of the Earths axis as it obits the Sun. This causes the atmosphere to be composed of distinct air masses that have different temperatures, different amounts of moisture and different atmospheric pressures. To add to the complexity the air masses are moving at different speeds and different levels above the earths surface. The Sun shines directly on the equator causing the countries surrounding or near the equator to be warmer. Whereas the polar regions (Antarctica) have very little or no contact with the sun meaning that the temperature in places like Antarctica would be very low and very cold. When the air in one region is warmer than the surrounding air, it becomes less dense and begins to rise drawing more air in underneath ( low pressure systems). Elsewhere, cooler denser air sinks,pushing air outwards to flow along the surface and complete the cycle ( high pressure systems). El Niño refers to the warm phases of ENSO (sea surface temperatures which are warm or cold for large periods of time). La Nino is referred to the cold phase. Temperatures and what to wear. Summer- Loose clothing, t-shirts, shorts etc Average temperatures :
QLD- 35-400c NSW- 30-350C
ACT- 25-300C
VIC- 25-300C
SA- 35-400C
NT-40-450C
WA- 30-400C
AUTUMN-
Warm during daytime- loose clothing, t-shirts,shorts. Cold during the night and early morning- warm clothing
weather- the weather is what the weather is currently in a short period of time. Climate- What the weather usually is overall throughout a long period of time.
2nd of march
partly cloudy southerly wind (20-25km/h) becoming light into evening anti clockwise around high pressure system o.5-1.0 swell 0-10mm rain 24-27 0c possible chance of rain 60-70% humidity 3rd march
mostly clear winds east to northerly (15-20km/h) Becoming light late evening a light troph coming in from the west causing light shades the next day no rain 0.5-1.0 meter waves 24-27 0c no storms
WINTER-
Very cold in the night and early mornings- Jeans, Tracksuit pants, Jumpers,Long sleeved shirts etc. Quite cold through the day- Jeans, Jumpers, Jackets, leggings etc.
A little less cooler than Summer but a little more warmer Autumn. A mixed arrangement of loose and snug clothing e.g- Jeans, t-shirts,shorts,jackets, jumpers etc
The difference in the climate around Australia is very significant according to the placement of the area. Northern Territory has the hottest climate because it is closer to the equator, whereas Tasmania has the coolest temperature as it is further away from the equator and closer to Antarctica creating a cold climate.
KEY:
Orange= A hot,humid summer
Lighter Orange= Warm, humid summer
Beige= Hot,dry summer. Mild winter
Yellow= Hot, dry summer. Cold winter
Green= Warm summer. cold winter
Blue= Mild/warm summer. cold winter
CLIMATE GRAPHS TO SHOW THE DIFFERENCE
This graph shows the average climate for Darwin 2014. As you can see, the lowest minimum temperature is 20 degrees c, which shows it does not get very cold in these areas. The rainfall statistics obviously show there is a great difference of the amount of rainfall throughout the year as there is a maximum of over 40 cm of rain in January and an average of 0 cm in July showing a great difference.The average highest temperature is up to 34 degrees c in September/October. The highest percentage humidity is 41%.
This graph shows the average climate of Hobart 2014. As you can see the lowest temperature on average is 5 degrees c which is a major difference with Darwin's at 20 degrees c, this shows that it is possible to get very cold in Hobart. The rainfall statistics show that Hobart gets 7cm maximum of rainfall on average in October whereas Darwin gets 4cm in October showing another great difference.The average highest temperature is up to 21 degrees c in January. The highest percentage humidity is 23%.
