Recently I was invited to talk to the computer science students at John Monash Science School by their wonderful teacher and all round superstar, Dr Linda McIver. The students had been working on different ways to show climate change data, Linda told me. Could we talk about that?
A chance to look at visualisations of climate data? How exciting! In five minutes I had a page full of examples to think of to share with the students. The presentation pretty much made itself.Read More »
No, I’m serious! Please, tell me what you think about this scenario.
A while ago I spoke at a small research meeting. I gave a 20 minute talk on my science. I engaged with my audience, answered general and specific questions, and hopefully came across as knowledgable and measured.
I also arrived early on the day of the meeting as the organisers had mentioned they would like some support. I carried piles of papers to the meeting room, helped to fill up water jugs, and dispensed snacks. When the meeting was over, I helped clean up.
None of the other meeting attendees did this. They’re all nice guys who work hard, respect their colleagues, and have all been in the team much longer than I.
When the other members of the forum arrived, I was there setting up water glasses, looking like a meeting organiser rather than an invited meeting member. I wondered, as I handed out agendas: am I helping my career here, or being alarmingly unhelpful?
Here I was thinking that providing an extra pair of hands is generally a good thing: it seems logical to me that helping out if needed is beneficial for your interpersonal relationships and career.
But maybe that’s not true? Maybe it’s rude and condescending to help with a job that is someone else’s, or professionally a bad look to set up the chairs for a conference at which you will be speaking?
The gender issue also crossed my mind. Assisting in unpaid activities overwhelmingly falls on the shoulders of female organisation members, particularly in academia.
While I have not seen this so much in my career to date, I did wonder if the other (predominately senior, predominately male) meeting attendees thought less of me because I was doing some non-academic tasks. Would they have thought more of me if I arrived late, looking frazzled and important?
I genuinely don’t know. But the experience left me feeling slightly uneasy, as though I had made a mistake.
Tell me what you think about this?
Do you help with jobs outside your core role?
Have you found it helpful, or is being helpful sometimes, well, not?
But historical wind records can be more like a drama queen than a reliable source of climate information: irrational and highly sensitive to the smallest changes.
Wind data can be subjective
Wind observations have been taken for centuries, long before technical weather instruments like anemometers were used. Observing wind strength and direction was a vital part of any sailors’ duties, at land and sea. While direction could be recorded relatively accurately using a compass, converting what you see around you to a number is a subjective thing.
Here, for example, is the famous Beaufort scale (discussed in loving detail in this book):
Now these descriptions are poetic, but what if you aren’t near a chimney, or any small branches?
Or, what if your wind strength scale had slightly different descriptions?
Francis Beaufort was not the only guy trying to turn the chaotic experience of wind into a numerical scale. During my recent work with historical wind data in Europe, I came across the Beaufort scale, a French wind strength scale and a nine-point strength scale used in Turkey. These indices all use different definitions to approximate the strength of wind.
Even worse, today, we use the speed of the wind to study it, so these values need to be converted to something approximating metres per second, or kilometres per hour, or knots, or cyclone scales, or tornado strengths.
Do you see where I’m going with this? Combining all of these different methods of measuring how strong and/or fast the wind is it a tricky job. It also means that we are comparing data with say, 13 different levels (0–12 on the Beaufort scale), with data that have many more (an anemometer can measure at 0.05 m/s intervals).
This is almost, but not quite, an apples and oranges scenario.
Also, wind data are mighty sensitive
Even once the Beaufort scale was replaced with good ole’ technology, wind data can still easily be rubbish, because they are extremely sensitive to the local environment.
This is fine if you are recording the wind at an airport for safe landings, or to see if a wind tunnel has accidentally been made, but if you want to look at large wind patterns over a long period of time, you might be in trouble.
The growth of a tree nearby, the erection (teehee) of a building across the road, or a small change in the location or height of the instrument can have a big impact on wind data. Temperature, rainfall and other weather variables can also be affected by these things, but wind observations are particularly fussy.
It’s not all bad
I realise it sounds a lot like I’m saying observing wind is a waste of time. But things aren’t quite that bleak.
Understanding local wind is really important for many things, like renewable energy, aviation safety and urban planning.
And, to be fair, wind observations taken at sea are generally much better than on the land, due to the lack of trees, buildings and other terrestrial nonsense.
Climate models are also pretty good at deriving large-scale winds from air pressure observations, so most long-term wind studies looking at climate change use models instead.
Finally, there are methods of correcting the non-climate features in wind data, if you are careful and have good information about the weather stations (it’s been done in Canada for example, and the Iberian Pensinsula).
But be careful next time you explore some old wind data. There’s a hidden drama queen in there, who might be telling you more about the neighbour’s pine trees than climate change.
People love talking about the weather. Whether it’s on Twitter in 2017, or in letters to the Editor in 1841, we are never short of a meteorological-based conversation starter, particularly in Australia.
The aim of these posts is to share some of the events that piqued people’s interest back in the day. Not always the hottest, driest, coldest or wettest day, but some days that got people whinging.
During this week in 1844, Sydney experienced a swing of temperatures which was echoed across the colony of New South Wales.
The Morning Chroniclereported a 6am temperature of 43ºF (6.1ºC) on the morning of 26 March 1844. This was the coldest March morning in the 10 years of published observations in the paper, although there is no information about where the thermometer was kept, so the data may not be that accurate.
Chilly mornings and premature frosts were also reported in the Hunter Valley, where correspondents claimed that the nights were “unusually cold for the season of the year”.
Two day later, on Thursday 28 March 1844, hot north winds with associated dust came upon Sydney in a late summer blast. George Peacock, the trained observer at South Head, on Sydney’s coast, wrote:
“At about two o’clock am came on to blow very hard from north and north-westward, and subsequently, during the morning, moderated: atmosphere bright and clear. Just at noon a violent squall of hot wind came over from north-west by north, carrying along with it clouds of dust—and continued a hot and very strong wind till near sunset — veering towards west-north-west; atmosphere being very thick and hazy, but cloudless.”
The highest temperature Peacock recorded that day was 87 ºF (30 ºC) at 2:30 p.m., up from 74ºF (23.3 ºC) at 8:30 that morning. The Chronicle reported a noon temperature of 80ºF, but interestingly a southeasterly wind, again suggesting that the observations weren’t done under the most rigorous conditions (read: maybe the paperboy took them??)
Regional correspondents also reported the hot blustery day. In Goulburn, southern NSW, the wind on the 29th was “unusually violent. Indeed the most disagreeable day we have had for a long season. Rain is much wanted to put the land in condition for the plough”. James Waugh at Jamberoo, also in southern New South Wales, recorded a maximum temperature of 90 ºF (32.2 ºC) in his diary (available at the State Library of New South Wales), with hot and windy weather.
The Hunter Valley felt the effects of the hot northerly too. On the 2nd of April, a Morpeth resident “of upwards of forty years” wrote to the Sydney Morning Herald of their fears that their sunflowers would “be apt to blights from the hot winds – that have been the case (in a great measure) this season”.
On the 6th, the word from Muswellbrook in the upper Hunter was that “The weather has recently been very sultry, and the late corn has suffered severely from hot winds”.
Hot winds like those experienced on 28 March are a common feature of Sydney’s climate. HC Russell, NSW’s Government Astronomer from 1870–1903, was interested in Sydney’s hot winds, dedicating several pages to the subject in his extensive 1877 summary of the climate of NSW. He wrote:
“Of all the features of the climate of Australia the hot wind is in many respects one of the most remarkable and interesting, as it is the key which opens the explanation of the whole of our wind system….In character this wind is the most disagreeable known in Australia.”
While the term wasn’t used at the time, the 28th of March sounds like a classic “brickfielder”, a strong dusty wind that blows during the summer months.
The term “brickfielder” was bandied about in the mid to late 1800s across southern Australia. According to this neat article, a brickfielder in the southern states was a hot dusty northerly, while in New South Wales it originally referred to a cool southerly wind which blew red dust from the brickworks into Sydney town.
It might be that in Sydney, a “brickfielder” was any old wind that brought dust with it. On 10 March 1836 for example, The Sydney Gazette and New South Wales Advertiser reported that a brickfielder had occurred “Tuesday last”.
The weather observations for that Tuesday last show a strong north north west wind, with high temperatures too.
In 2010, the Australian Meteorological and Oceanography Society ran a competition to give Melbourne’s dusty winds their own name, with the winner being the “Northerly Duster”. Is it yet to catch on.
As a remote researcher I am free to work wherever I like, keeping my own hours, and maintaining a level of dress sense that would embarrass most of you.
But despite the freedom that working from home provides, I’ve found that the days tend to slip into a weekly cycle. This is good for my sanity, and for my tracksuit pants, that do need a wash every now and again.
Monday: Home day
I dawdle out of bed at 8:30am, safe in the knowledge that it is still Sunday night in Europe and I have the whole day to prepare things for my colleagues’ Monday morning. Also, my commute is four seconds long. Trackies will remain on all day and productivity is high due to a lack of office distractions.
At about 11:30am I remember the pot of tea I brewed at 10am, and realise why tea cosies are such a good idea. Talking to myself and singing along to the radio while working are standard behaviours on a Monday, as well as a little indulgence of daytime television.
Tuesday: Chore day
Time to brave the outside world and buy some food. Might even put a load of washing on, and do the dishes. Tracksuit pants remain the uniform until lunchtime, when I head to the market and run those mail-collecting, appointment-making errands that you can only do from 9am to 5pm. This takes up most of the afternoon, meaning I am working frantically when 6pm comes around, ready to chat to colleagues who have just started their day. Emails are the last thing I see before I go to bed.
Wednesday: Friend day
Emails are the first thing I see when I get up. For all the freedom of being a roving researcher, the time difference does make it hard to switch off from work. To combat that, I have lunch with a friend and her newborn, again relishing the things that you just can’t do if you work in an office. Plus it gets me out of the house. Cut to 7pm and I am attempting to work, bring in clothes and prepare dinner at the same time. So much for no distractions.
Thursday: Outing day
After three days of being home-based, it’s time to go rogue. My home Internet is struggling to upload the data I need to send to Europe, and my tracksuit pants are starting to smell. Off to the city for me!
I start in a café, feeling like one of those stylish people who work on their laptop in a café. I listen to some St Germain while I code and drink too much tea and try in vain to get the free wifi to upload 5GB of data. I leave, hepped up on tea and busting for the loo, and hole up in a university library instead. Here the toilets are free and (if you’re lucky) the eduroam Internet works. I might even organise a work meeting with a local collaborator, to remind myself of the wide and wonderful world of research in which I am still living. How fun to have an outing!
After yesterday’s exhausting outing. I’m ready to bring in the weekend with another productive day at home. Might even stay in my PJs for a while and start working early, before my brain wakes up enough to procrastinate.
While working from home means that you can really do it at anytime, I try to keep my weekends for living. I attempt to draw a line under what I have done for the week, and set things up to start well the following Monday. In reality, this means making a long list of things I haven’t quite finished, waiting for me and my pot of tea on Monday morning.
This, so far, has been my experience of working remotely. Is it how you work from home? How do you stay motivated when working by yourself? How does one make a good tea cosy? Please, let me know!
A couple of weeks ago I was lucky enough to receive a ERASMUS+ Mobility Grant to visit one of the pillars of climate science, The University of East Anglia’s Climatic Research Unit.
CRU is responsible for one of the most widely-used long-term climate datasets in the world, the HadCRUT record. It also has an impressively long history of historical data research. I was therefore really excited, and pretty nervous, when I got off the double decker bus at UEA on Monday morning. I was going to meet my heroes, peoples whose names I only knew from my well-thumbed copies of their papers. Eep!Read More »
This week, I have had the unadulterated luxury of being on holiday. And not a travelling holiday either: a plonk yourself next to the pool, sunset drinks, working on your tan, proper vacation. Although it’s been great, these kinds of breaks are not my usual fare. I am much better at seeing and doing than I am at sitting still.
Plus, like most scientists, I couldn’t quite shake what Dr Climate refers to as holiday guilt — the idea that I should really be working rather than lounging around. While I know this is common for most people, it seems particularly rampant in academics.
Obviously, too much work and not enough play is bad for your mental health and work productivity. But, if you have to address your gnawing conscience, is there some good that can come out of a little bit of work in between swims?Read More »
A couple of weeks ago I was lucky enough to attend the European Geosciences Union conference in Vienna, affectionately and efficiently known as EGU.
Over 13,000 scientists from across the world get together for a week to discuss the centre of the earth, far flung space and everything, literally everything, located in between. Seeing so many researchers together, in so much comfortable footwear and with such a wide array of backpacks, is a special experience indeed.
This was my second EGU, but my first as a grown-up scientist rather than a student. The first time was completely overwhelming, and I left thinking that mass meetings were not my scientific bag.
But this year was very different. I got some useful feedback on my work, met heaps of new people in my field, connected with some people I’d been longing to collaborate with, and re-connected with great old colleagues and friends.
I am a bit more experienced now it’s true, and know a few more names and faces. This year I was also fortunate to give a talk , and give it at the start of the week, meaning that a) my presentation was out of the way early and b) the few people who did see my talk had more time to catch me and ask questions.
But I was also more prepared this year, and I think I’ve figured out a few of the dos and don’ts (dont’s?) of EGU. They are, in the order that I thought of them…Read More »
When people ask me what I do here, my standard response is “Soy investigadora, en el Centro de Cambio Climatic”. Most people take this to mean that I work with the political and economic solutions required to solve the diabolical problem of climate change (which they then quiz me about), but sadly this is not true.
I work with old weather.
Yep, old numbers. Historical weather observations taken up to 250 years ago. I find them, digitise them, and check them to see how reliable they are.
When I occasionally manage to explain this in my basic Spanish, people generally look disappointed, confused, and then they slink away.
Recovering old weather data is not at the “coal face” of climate change research (haha, pun), and many people may think that it’s not really important for helping us figure out how we are going to manage the future.
Today is the anniversary of the First Fleet’s arrival in Sydney Cove, only 228 years ago. A defining moment, certainly, although more and more people agree that the 26th of January is not the right day to honour all things Australian.
To commemorate the date, let’s have a look at Australia’s earliest weather observations. Their history, funnily enough, began at exactly the same time…Read More »
