Recent Australian flooding and cyclonic events can be largely explained by a strong La Niña.

Modern technology lets us see how big hurricanes are and track them through satellite imagery, while storm-penetrating aircraft measure their strength, in terms of wind speeds and atmospheric pressure. That technology gives us detailed warnings that people a century ago never had. Hurricanes usually form in the tropical zones north and south of the equator, where warm waters offer ample fuel for storm formation.
