The biggest Australian Weather Stories Of 2022
( source: Weatherzone )

What a year. This will be remembered as a wet year in Australia, with La Niña dominating local weather across large parts of the country. But as always, there was plenty of remarkable weather of all types in all states and territories.
Here's our quick rundown of the some of the most significant weather events, month by month, as we covered them here in our news feed at Weatherzone.

JANUARY
First Aus 50-degree day this century
January 13, 2022, was an historic day: the 50.7°C reading at Onslow Airport in northwest WA was the first time this century that any Australian location has reached the 50-degree mark. It was also WA's hottest temperature and the equal-hottest Australian temperature ever recorded.

Heaviest Aus rain day in 3 years
A whopping 674 mm of rain fell in 24 hours at the weather station at the rural locality of Marodian, about 40 km southwest of Maryborough (Qld) in the catchment of the Mary River. This was the highest 24-hour rainfall tally anywhere in Australia since 2018. As you'd imagine, flooding was severe.

FEBRUARY
Perth's hottest summer
Early in the month we wrote that Perth was on track for its highest number of 40-degree summer days, and so it turned out. In fact, the WA capital had its hottest summer on record, with an average max temp of 33.3°C – a whopping 2.5°C above the long-term average.

Heavy outback rain
It started in the last days of January but spilled into February, as Broome Airport recorded a 120-year high of 563 mm of rain in 48 hours – more than it received during the whole of 2021! Meanwhile for the second time in three months, Alice Springs saw more than 100 mm within the space of three days or less, and the normally dry Todd River again raged.

Record Brisbane rainfall
Brisbane broke two major rainfall records late in the month – with a three-day total of 676.8 mm and a weekly total of 795 mm. Widespread flooding ensued, and tragically, six people lost their lives in or near the city.

MARCH
Unbelievably soggy Sydney
Heavy rain in February (total 356 mm) ensured that Sydney recorded its wettest summer in 30 years, but that was just a sign of an extremely soggy year to come. Sydney would go on to register its wettest March on record with 554 mm. Normally the heaviest monthly rainfall totals occur along Sydney’s coastal fringe, but Penrith in the city's outer west recorded even more than the city, with 592.8 mm. Flooding was widespread.

Lismore floods
If one single event defined 2022, it was surely the Lismore floods, although the list of places that flooded in March was long, and included places as geographically diverse as Byron Bay and Broken Hill.
www.weatherzone.com.au/news/two-weeks-on-lismore-locals-fear-they-may-never-recover/536653

APRIL
More heavy rain (but no bombs)
There was yet more heavy east coast rain, as Sydney exceeded its annual average rainfall less than a third of the way through the year. But did it experience a "rain bomb" as many media outlets reported? As our story explained, no!
www.weatherzone.com.au/news/is-a-rain-bomb-hitting-nsw/536945

Surprisingly quiet tropical cyclone season
Australia's tropical cyclone season runs from the start of November until the end of April. Like the previous season, the 2021/22 season was quieter-than-average despite La Niña, which usually helps boost cyclone numbers. There were nine tropical cyclones that formed in or moved through Australia's area of responsibility, two of which made landfall over Australia. The long-term average for the Australian region is 9 to 11 tropical cyclones and four coastal crossings, according to the BoM.

MAY
Heavy flooding in SE Qld and Tas
Queensland and Tasmania are two states you don't often see mentioned together in weather, but we've thrown them in together here, because both saw exceptionally heavy rain in their southeast corners. The Tassie rain was particularly noteworthy, not just because it was so heavy, but because it fell in the (normally much drier) eastern half of the state. Southwestern Tasmania, which is Australia's wettest non-tropical area, continues to experience a rainfall deficit by historical standards, something we wrote about in March.

JUNE
Best start to Aussie snow season in decades
It was actually the best start to an Aussie snow season since 1968, after back-to-back blizzards – the first of which started in the last two days of May – left over a matre of snow in the higher mainland ski resorts. The ski season went on to be a beauty, with a peak season depth of 232 cm at Snowy Hydro's measuring site at Spencers Creek, NSW. That's around 10% higher than the average peak depth in the data set going back to 1954, although it's worth noting that the snow at lower elevations was extremely patchy this winter, and often non-existent.

JULY
Yet another east coast deluge centred around Sydney
After 300 mm in 48 hours recorded in parts of the Sydney metro and Illawarra regions, plus a whopping reading of 521 mm at one location, Sydney itself would go on to register a record total of 404 mm of rain in July, the second-wettest month of a very wet year.
www.weatherzone.com.au/news/more-than-300mm-of-rain-in-48-hours-how-unusual-for-sydney-and-illawarra/668016

AUGUST
Rare winter warmth for Tassie
Towards the end of the month, Hobart recorded a 21-degree day, while Strahan on the state's west coast registered its warmest August day in records dating back to 1971, after reaching 22.5°C. Interestingly, Tasmania had an exceptionally poor snow season, with little skiable snow all winter at its two small ski hills. This was in stark contrast to the mainland.

SEPTEMBER
Wet start to spring
There was flooding in four states after a relatively slow-moving rainband drenched eastern Australia early in the month. As Weatherzone meteorologist Ben Domensino pointed out at the time, the combination of a low pressure trough, cold front and a low pressure system being fed by abundant moisture coming from the oceans surrounding Australia is a normal kind of set-up for September.
But the atmosphere was loaded with more moisture than usual thanks to three active climate drivers: The negative Indian Ocean Dipole (IOD) to the northwest of Australia, a La Niña-like pattern to the northeast of Australia, and a positive Southern Annular Mode (SAM) to the south of Australia.

OCTOBER
You guessed it, more record-breaking NSW (and ACT) rain
On the 6th day of the month, Sydney surpassed its longstanding annual rainfall record of 2194 mm. By the 24th, it had also shattered its October rainfall record, and ended up receiving 295.4 mm for the month (for the record, Sydney would top 2500 mm by the end of December). But it wasn't just Sydney copping a drenching. Canberra had its wettest October on record with 166.2 mm, in what has been one of its wettest years on record. Outback NSW also copped some serious rain in October, all the way out the back o' Bourke.

Devastating Victorian and Tasmanian floods
Also this month, our two southernmost states, Victoria and Tasmania, got a taste of what eastern NSW and southeastern Queensland had experienced all too often in 2022, with severe floods which one local told Weatherzone was the worst he could remember. Extremely heavy falls by Victorian standards, including 224 mm in two days at Strathbogie North, inundated rivers like the Goulburn and other major tributaries of the Murray. All that water soon flowed through towns like Shepparton and Echuca, which experienced severe flooding under sunny skies when the system that brought all the rain was long gone.

NOVEMBER
Late spring Aussie avalanches!
Melbourne Cup Day was one of many freezing November days down south, and the unseasonable cold fronts that swept through the southeast delivered frequent snow to the Alps. One fall was so heavy that avalanches were triggered in the NSW back country.

Thousands were without power as intense storms moved through southeastern SA. A rare combination of factors caused the devastating storm outbreak, which we explained in this story.

DECEMBER
Cool start to summer down south, hot start up north.
Australia equalled its coldest summer temperature on record, when Perisher Valley in NSW dipped to -7°C on the morning of December 9 after yet another out-of-season cold front. Most of the southern capitals have had a relatively cool December in relation to their long-term averages, while even Brisbane failed to top 18°C during daylight hours one particularly unsummery summer day. Meanwhile there was a heatwave in WA, NT and parts of Qld and SA.

Sydney Has Longest Spell Of Days Below 30 Degrees Celsius In 140 Years
(source: farmonline weather )

As most of southern Australia sweats under a prolonged heatwave, Sydney is on the verge of recording its longest spell of days below 30 degrees Celsius in 140 years.

While the weather has definitely at least resembled a version of summer since the pre-Christmas record cold spell, Tuesday's maximum of 26.6 degrees at Observatory Hill marked the 323rd consecutive day under 30C, already the longest stretch in three decades.

Sydney's maximums are forecast to remain below 30 through the remainder of this week, extending the run of sub-30C days to at least 327, the most since the record of 339 days from 1883.

A rare year without 'hot' weather

Considering Sydney's weather station averages 15.2 days above 30C each year, to record nearly an entire year without reaching 30C is exceptionally rare.

What makes this run even more irregular is in a global warming world the number of days where the temperature reaches 30C has been increasing during recent decades.

So far this century, the average has risen to 22 days per year and each year from 2017 to 2020 saw at least 30 days.

The last day above 30C was February 21, but Sydney did not record one day last year above the Bureau of Meteorology's threshold for a "hot" day, which for non-tropical coastal regions is 32C.

This means Sydney has not officially been "hot" in more than 12 months, as 2022 was the first year since records commenced in 1859 to stay below 32C.

[graph]Sydney only recorded seven days above 30C in 2022, well below the 30-plus days from 2017 to 2020

Where have the summer scorchers gone?

The mystery of Sydney's missing heat is a similar riddle to the record wet in 2022. The answer is blowing in the wind.

Averaged across an entire year, Sydney's most common wind is a westerly, however, in the past year the most common wind was an easterly.

During the warmer months, an easterly airstream is cooler than a westerly as the water temperature in the Tasman Sea, to our east, never climbs above about 23C.

That is well below the 45C air masses inland Australia is capable of producing during summer.

Even on days when a westerly, or a warm northerly, has blown across Sydney, either a sea breeze has developed by the afternoon or skies have been cloudy enough to keep the temperature below 30C.

When will Sydney finally reach 30C?

Through this week, winds will continue to blow from the east which should keep Sydney's maximums close to average.

The next chance of either a westerly or a northerly which could send Sydney to 30C is around the middle of next week, however that is certainly not guaranteed and it will depend on the exact timing of afternoon sea breezes.

The all-time 1883 record of 339 days without reaching 30C is even under threat as the easterly wind deviation is forecast to continue into February.

To answer the questions posed by some re how heatwave warnings are issued by the BoM.

"The Bureau of Meteorology defines a heatwave as three or more days in a row when both daytime and night-time temperatures are unusually high—in relation to the local long-term climate and the recent past. There is no single temperature threshold for a heatwave in Australia. For each part of the country, the Bureau compares the forecast maximum and minimum temperatures for each three-day period in the coming week (e.g. Monday–Wednesday, Tuesday–Thursday) to the 'normal' temperatures expected for that location at that time of year, and to observed temperatures over the last 30 days. Heatwaves are classified into three types, based on intensity. Comparing forecast temperatures to the last 30 days of temperatures allows the Bureau to gauge the size of the temperature change, physical and behavioural preparedness for such heat, and how challenging it could be for people and infrastructure: 1. Low-intensity heatwaves are the most common—most people are able to cope with this level of heat.
2. Severe heatwaves are less frequent and are challenging for vulnerable people such as the elderly—particularly those with pre-existing medical conditions.
3. Extreme heatwaves are the rarest kind. They affect the reliability of infrastructure, like power and transport, and are dangerous for anyone who does not take precautions to keep cool—even those who are healthy. People who work or exercise outdoors are particularly at risk. The heatwave product includes two heatwave assessment (last two three-day periods) and five heatwave forecasts (three-day periods) starting on each of the next five days.
Caution. The maps provided by the Heatwave Forecast will show a reduced severity level or remove the indication of heatwave before the heatwave actually ends. This occurs because the maps are calculated across today, tomorrow and the next day. If the temperature is lower on the last day(s) then the map will indicate a lower risk despite unusually hot conditions being present for the first day or two. The Heatwave Assessment will show how heatwaves are finishing due to the combination of recent days with the current forecast days."

Vioolsdrif's temp record from 2019 wasn't all over the headlines for a reason.

web.archive.org/web/20191203153526/http://www.weathersa.co.za/Documents/Corporate/Medrel2Dec2019b%20Vioolsdrif%20temperature.pdf

The South African Weather Service publishes a Daily Weather Bulletin that provides weather statistics on a daily basis. This data comes directly from the instrumentation and is not yet quality controlled, therefore it is considered preliminary data. A maximum temperature record of 50.1 °C for Vioolsdrif weather station for the 28th of November was reported on the Daily Weather Bulletin last Friday (29 November 2019). The South African Weather Service realised that if the record is correct it would mean a new national record for South Africa.

Investigations into the data from the station revealed that the temperature sensor had just been replaced two days prior, and a decision was made to track the behaviour of the station over the weekend. The analysis of this data showed that the behaviour of the temperature sensor was questionable and the preliminary temperature reading of 50.1 °C as a new record is therefore invalid.
The South African Weather Service would like to thank the public for their keen interest in this matter.

It's been an snowing like crazy today. An Indian guy in work started facetiming his wife to show her and she was crying, turns out it was the first time he'd never seen snow before. It was cool to watch, but I think he enjoyed it a bit too much, he's probably out having sex with a snowman as I type this.

Well here we are in the grips of another cold spell. A lot of frost on the ground the last day in particular, but generally clear skies, of course which had allowed the temperature to drop well below freezing. The increasing light of the evenings is encouraging, and that there are merely 41 days of meteorological winter left; not withstanding that nasty cold spells are always possible well into late March, understandably.

Indoor temps in Europe in summer tend to be hotter in the south. Of course. It would be interesting to see south versus north for Spain and Italy.

A lot of Americans would consider 25C too hot inside. AC is more common here though. I don't know what the average indoor temp is. Probably hottest somewhere like Phoenix and coldest in Alaska.

Crunch41 It's a cold 68 F (20 C) in here right now so I think those southern European indoor temperatures would feel heavenly right about now!

With no AC, and radiator heat controlled by the landlord, I've seen the full gamut of indoor temperatures since moving in here in August: 17-31 C. I got to feel most of that range just in December alone (though the highest temp was on a warm humid day in September).

Lmao @ these typos in the Abstract of this study regarding explosive cyclogenesis:

journals.ametsoc.org/view/journals/mwre/116/8/1520-0493_1988_116_1568_ecoteu_2_0_co_2.xml

Cases of explosive cyclogenesis (“bombs”) were identified over the central and eastern United States and were compared with nonexplosive cyclone development in the same region. The tendency equations for vorticity and geopotential thickness, and a modified divergence equation were used to find signatures of distinction between these two types of cyclogenesis, whose recognition might improve forecasting skills.

Bombs tend to show a marked decrease of vorticity with height during their incipient and explosive stages, whereas regular cyclones reveal only weak vertical vorticity gradients in the troposphere. The low-tropospheric spin-up in bombs precedes significantly that in the upper troposphere. Preexisting low-tropospheric vorticity maxima are associated with low-level jet streaks.

Whereas regular cyclones possess an ill-defined level of nondivergence (i.e., a broad region between 800 and 400 mb, of divergence values close to zero), incipient bombs have a well-marked zero-divergence level near 500 mb, associated with a sharp maximum of rising motions.

We observed a marked increase in large-scale latent beat release between the incipient and the explosive phases of bomb development. The convective component of latent beating shows a distinct maximum in the incipient phase of bombs and a decrease which continues through the explosive and mature phases. Regular cyclones show much less heating and much less change between the phases of development than is observed with the bombs. Static stability reveals little change as the bomb grows and mature. There also is little difference between the stability associated with bombs and regular cyclones.

Steelernation That 104°F record high last year in Smithfield NC (COOP) doesn't look accurate to me (sites nearby in Clayton and Goldsboro maxed out at 99-100°F), I think the hottest legit site is 102°F @ Turnbull Creek (RAWS).
