Your blog task this weekend is an easy one.
We have been talking about Weather and what causes it.
Weather in Victoria can change rapidly, and there are four key influences:
Enso: (El Niño Southern Oscillation) rounds up tropical moist air in the Equatorial Pacific Ocean.
Ridgy: (Sub-tropical Ridge) and high pressure systems can block rainfall in Victoria.
Indy: (Indian Ocean Dipole) delivers moisture from the Indian Ocean.
Sam: (Southern Annular Mode) influences the strength and frequency of cold fronts over Victoria.
This may make sense in action:

You task is to try and tell me (post a comment below) what you think it is all about!
(We will be talking more about these climate processes more in future classes)
Victoria is well known for its variable climate. From year to year, four global climate processes vary their behaviour, potentially resulting in wetter or dryer seasons.
Explore ‘The Climatedogs’ below and learn how these four drivers work by herding rain towards or away from Victoria.
