- tropical cyclones (typhoons) may strike southeast and east Asia from May to December
Southern Ocean

- in winter the ocean freezes outward to 65 degrees south latitude in the Pacific sector and 55 degrees south latitude in the Atlantic sector, lowering surface temperatures well below 0 degrees Celsius;
- at some coastal points intense persistent drainage winds from the interior keep the shoreline ice-free throughout the winter
