Local weather
Canterbury is on average cooler than the rest of New Zealand with below zero temperatures common in winter and occasional snow falls.
In spring and summer airflow over the Southern Alps causes a strong, hot, and dry wind known as "the nor'wester" usually along with lenticular clouds known as the "nor'west arch".
Flooding is not uncommon after heavy rainfall as the Canterbury Plains is home to a number of braided rivers, and the Ōtakaro Avon and Ōpawaho Heathcote rivers run through Christchurch city.
Christchurch records over 2000 hours of sunshine a year.

Cyclones, Hurricanes, Typhoons, and Tornadoes
What is the difference between these different kinds of weather?
A "cyclone" is a system of winds that rotate around a central area of low pressure. Cyclones that start in the North Atlantic, central North Pacific, or eastern North Pacific are called "hurricanes". When they develop over the South Pacific or Indian Ocean the are called "cyclones", and when they form in the North West Pacific they are called "typhoons".
A "tornado" is a twisting column of air that forms from a storm. They also sometimes called "twisters" or "whirlwinds". Tornadoes can have diameters in the hundreds of metres but cyclones are more likely to take up hundreds of kilometres.
Cyclones of all kinds and tornadoes all rotate in a clockwise direction in the southern hemisphere (or anti-clockwise in the northern hemisphere).
