Heat and cold

Australia is not only a dry country, but is also subject to fierce heat. As the sun tracks into the southern hemisphere in early spring, it begins to strongly heat northern and interior parts of the country. By November, average maximum temperatures have already climbed to the high 30s over wide areas of northern and central Australia - and into the low 40s in parts of northwestern Australia and western Queensland. The heat does not relent until the following autumn.

Heat waves

On occasions when the synoptic situation is favourable, the hot air extends south over the southern States. In South Australia and the southeast, this occurs when high pressure systems lie to the east, and a cold front is advancing from the west - a combination that directs a hot northerly airstream across these states. In southwestern Australia, the hottest conditions are normally associated with low pressure troughs that direct east to northeasterly winds from the hot interior. In both cases, eastward movement of the front or trough introduces cooler air from the oceans or higher latitudes - the so-called, and often eagerly awaited, “cool change”.


These “hot weather” patterns occasionally become slow-moving, and the trough or front bringing the cool change may stall, or even dissipate. On such occasions, very high temperatures - high 30s or even 40s - can persist for days, and in inland areas, for weeks on end. These are the “heatwaves” of the southern States. Such heatwaves can lead to heat exhaustion, and even death, particularly among the very young or old. Heatwaves have, in fact, accounted for more deaths in Australia than any other natural hazard: according to Emergency Management Australia the January 1939 heatwave in South Australia, Victoria and NSW killed 438 people.

 

Before Ash Wednesday, dry northerly winds ahead of a cold front

 “A typical hot weather situation over southeastern Australia, with hot, dry northerly winds ahead of a cold front. This situation, on 16 February 1983 - the day of the Ash Wednesday bushfires in Victoria and South Australia - produced temperatures up to 45°C”

Cold and snow

Icicles in CanberraOn the other hand, Australia is largely spared the extremes of cold that afflict many northern hemisphere countries in Europe, North America, and Asia. Snow is rare outside the highland areas of southeastern Australia, and is a noteworthy event when it does fall to low levels. Snowfalls at sea-level are rare, even in Tasmania, and exceptionally rare on the mainland. The path taken by a cold air mass largely determines the location of a snowfall, and occasionally a northward-moving pool will bring snow along the Great Divide as far north as southern Queensland. A typical synoptic situation producing a cold outbreak is when south to southwesterly winds rapidly transport very cold air northward from far southern latitudes.

Low overnight temperatures in Canberra during July 1994, combined with a malfunctioning automatic sprinkler, produced this display of icicles on play equipment at a Canberra pre-school centre (courtesy of Gary Schafer, Canberra Times).

At the higher elevations of southeastern Australia snow often persists for weeks or months at a time. In most years there is enough snow above about 1500 metres for a viable ski industry. However the amount of snow that falls can vary substantially from year to year: in some years, such as 1973 (when it was too warm) and 1982 (too little precipitation), the ski season fails. The fact that 1973 was a La Niña year (SOI highly positive) and 1982 an El Niño year (SOI highly negative) reflects a generally poor relationship between snowfall and the SOI. On the other hand, some years (such as 1981) have abundant snow and a “bumper” ski season. In recent years, snow- making machinery has reduced this uncertainty somewhat, although seasons of heavy snow are still welcomed - provided the depth does not become so great as to make ski tows inoperable.

One third of Australia braces for an Antarctic blast

While much of the country has been enjoying balmy winter days under a broad high pressure system, the far southeastern corner has been experiencing strong, brisk winds and showers throughout most of the week.

The blustery conditions have been the result of a series of fronts traversing the far south of Australia this week. The front to rule them all, however, is yet to come and is due to affect Adelaide and Melbourne first tomorrow.

Record hot June for the world

ABC image

Last month was the hottest ever June worldwide, according to the National Oceanic Atmospheric Administration in the US, which tracks climate data over ocean and land.

Records date back to the 1880s... It followed the hottest May ever.

Blair Trewin, a climatologist at the Australian Bureau of Meteorology, says the record temperatures have to do in part with the coming El Nino, which raises global ocean temperatures, meaning bigger tropical storms in the Pacific.

Sub-zero arctic blast strikes US

Sub-zero arctic blast strikes US

New York (AFP) - 6/1/14 Millions of people across the United States on Monday made last minute preparations for an unusually bitter Arctic blast that could send temperatures plummeting to their coldest in 20 years.

 

The northeastern United States and parts of Canada have endured heavy snow and deadly sub-zero conditions since the start of the year, but the deep freeze is now moving through the midwestern United States and threatening usually balmy areas further south like Tennessee and Alabama.

Frigid air from the North Pole: What's this polar vortex?

(CNN) -- Americans in two dozen states from the Midwest to the Southeast and Northeast are shivering this week courtesy of a distorted polar vortex. The rush of cold air it's sending southward is the biggest visitor from the North Pole since Santa Claus. The gifts it brings, however, are chilling and generally unwelcome. Much of the United States has plunged into a deep freeze from record low temperatures.
