Last year was a year of record-breaking weather events, ending with a bang of explosive cyclogenesis in the North Pacific on New Year's Eve.
The extratropical storm saw its central pressure fall to a record 921 millibars from 972 millibars in 24 hours, making it the strongest storm in that basin in at least 60 years, and also setting records for Alaska and the Bering Sea in its path onwards.
Meanwhile, a global record for the highest mean sea-level pressure was broken in Mongolia, central Asia, barely days before. A recording of 1094.3 millibars came hand-in-hand with bitingly low temperatures of -45.5C (-50F) in Tsetsen-Uul in the western Zavkha province.
This year, on the other hand, opened with a disruptive ice storm across the midwest and Great Lakes of the US. Ice storms, or freezing rain, occur as raindrops falling vertically through the atmosphere move into a thin layer of sub-freezing air near the earth's surface. This allows the droplets to become supercooled and freeze upon contact with any objects, creating extremely hazardous conditions such as ice coats the ground. In the southern hemisphere, the first storm of the season was birthed. Tropical Cyclone Imogen made landfall in the Shire of Carpentaria in Queensland, Australia, on Monday, with reports of over 260mm of rain falling in Karumba.
