Rainy season in Australia
The Southern Hemisphere summer falls in the months of Dec-March. Rains are common during 70% of these months. Of all these January is the wettest.
Why and when are severe rains in Australia and New Zealand?
During summers, the Pacific waters evaporate easily. They pump up moisture in the atmosphere. When the cool breeze touches these vapours in the evening, they condense and rain! Australia (and New Zealand) also gets snow. June to August are the snow seasons in the country.
Cyclone Gabrielle spins clockwise
All the cyclones in the northern hemisphere rotate anti-clockwise. And the cyclones in the southern hemisphere rotate clockwise direction. This is because of the Coriolis force of the earth.
