AMetA

Welcome to the Australian Meteorological Association Inc.

Regular meetings resumed in February 2021

Prior to COVID-19 our bi-monthly meetings were held in a conference room at the Bureau of Meteorology in downtown Adelaide. Since February 2021, however, we have resumed meeting every two months, as in the past, but in a NEW LOCATION: St Savior’s Anglican Church, Glen Osmond.

The AMetA Committee is investigating a suitable longer-term solutions for our meeting venue.

Next Meeting on Monday 18th October 2021

Speaker: John Nairn, BOM Regional Director

Subject: Heat Waves – Our Deadliest Weather

Where: Caledonian Hotel, 219 O’Connel St, North Adelaide

Time: Meeting 6:30 PM t0 8:00 PM

Please remember that current Covid rules limit the number of attendees at a meeting. Consequently “tickets” have been considered necessary for planning purposes – these tickets are free, but please book them via eventbrite (using this LINK). This link also provides some background for the talk.


PWS Activities have Commenced !!

PWS (Personal Weather Stations) activity finally kicked off on Sunday 20th June 2021 in the Greenacres Library, which is located at 2 Fosters Rd, Greenacres (near the corner of NorthEast Rd and Fosters Rd, Greenacres).

Mark Little (AMetA President) represented AMetA at a meeting for people interested in IoT (Internet of Things). His aim was to investigate whether air-quality monitoring could be an appropriate activity for AMetA participation, at least to get us started!

This LINK will give you some idea of what the IoT is all about.

Mark has written an update on PWS activity – see page 4 of the August 2021 edition of the AMetA Newsletter (Monana).

at St Savior’s Anglican Church,

596 Portrush Road, Glen Osmond.

Weather and Climate ForecastingWhat’s Changing? Paul Lainio, BOM

Weather radar, satellites, drifting buoys, super computers –  just some of the sophisticated technology used to produce weather forecasts.

The Bureau of Meteorology is a household name. Whether we want information on heatwaves, bushfire weather, flood warnings, the likelihood of ‘opening rains’, or just the daily forecast – everyone – somehow or other – relies on meteorological information to help make decisions. An era of rapid technological change has enabled the Bureau to increasingly sharpen these services with expanded, accessible and more accurate weather information.

Our speaker, Paul Lainio is the popular and recognised face of the South Australian Weather Bureau. He will outline how short-term weather, and longer range seasonal and climate services are changing with advances in data access, radar, and atmospheric modelling.

Many will be astonished to realise that the first next-day temperature forecast in Australia only occurred in the lifetime of many current citizens! Before that the forecast was general in nature, “tomorrow will be fine, cold to cool, light variable winds”. It was only 15 years ago that the Bureau commenced 7-day temperature forecasts and the estimation of rainfall amounts. We can now examine over the web, detailed maps of rain and temperature for the whole continent for the next three months. The forecasting horizon has gone from 7 to 90 days! 

Paul has worked with the Bureau during this time of rapid changes. His easy speaking style and his depth of knowledge creates an opportunity not to be missed. With COVID restrictions, seats are limited, so please book now.


Previous Meeting (June): “Where Meteorology and Fire Come Together

Speaker: Dr Mika Peace, Bureau of Meteorology

Traditionally, meteorology concerns itself with large scale movements of weather systems over longer scale time periods. We understand that prolonged droughts coupled with hot windy weather can be a lethal combination for starting bushfires in Australia. We have had several notable reminders of this fatal relationship and the Bureau of Meteorology states that, with climate change, “Bushfire weather conditions in future years are projected to increase in severity for many regions of Australasia”.

Recent research has focussed on understanding the complex inter-relationship between meteorology and bushfires which varies with each occurrence. These fire-atmosphere interactions happen at different scales from micro to meso (intermediate) and are critically important in anticipating fire behaviour and how effectively we can react to each incident.

Dr Peace, working from the Bureau of Meteorology, is a lead researcher in the Bushfire and Natural Hazards Cooperative Research Centre. She has a national profile, extensive practical experience in fire weather and a wealth of knowledge of major bushfires across Australia. A practiced public speaker, she will discuss basic fire-atmosphere interactions, outline the learnings from the 2019-20 Black Summer fires, and emphasise the importance of developing relationships between Australia’s extensive emergency management agencies.


Monana Publications

To maintain virtual contact with our members during the hibernation, we began producing monthly newsletters, alternating between the traditional Monana series and a new series which is mainly directed at people with an interest in personal weather station (PWS) issues, although probably also of interest to most of our members. Both series of newsletters have been made visible in the Members Area of this website (Visitors Welcome!).

The June 2021 issue of Monana can be viewed HERE.

The August 2021 issue of Monana can be viewed HERE.

The March 2021 issue of the PWS newsletter can be viewed HERE


Historical weather update

Mac Benoy, AMetA Citizen Science Team Leader

An item of great interest to AMetA members was presented on page 3 of The Advertiser on Thursday 9th July 2020. It was written by Miles Kemp – read a sample below.

The discovery of an extensive 150-year-old diary has filled a key gap in Adelaide’s colonial weather history and will (complete) one of the longest continual records in the Southern Hemisphere. The diary contains crucial weather details from 1843 to 1856, including rainfall, temperatures, cloud types and even barometric pressure, meticulously recorded in longhand.

AMetA project manager Mac Benoy said the discovery was part of a 15-year search by local volunteers to find colonial Adelaide’s missing weather records.”

A comprehensive explanation of how this information is being exploited is available on pages 2-7 of the October 2020 AMetA Newsletter (Monana), which may be viewed HERE.

* * * UPDATE * * * At the recent April 2021 AMetA Meeting, Mac Benoy gave a presentation entitled “Preserving our Historical Record” to a small but enthralled audience. Mac concentrated on SA Regional Office National Weather Folios from 1879-1957, relating his story to the technological advances taking place during the early days of SA white settlement.

Slides used in this talk may be viewed HERE. Mac intends to add some text to flesh out the slides, but in the meantime it might be helpful to have first read the “comprehensive explanation” referred to in the paragraph above. PLEASE NOTE: The slides file is a fairly large (about 35MB) so might be a bit challenging for older devices! Also note that the slides reside on the Dropbox cloud so you probably need to have Dropbox installed on your device. (Meanwhile, I am trying to put an alternative version on the website server.)


Monthly Prizes still to be Won?

  • SORRY, BUT TIME HAS FINALLY RUN OUT!

You were asked to write a short article with some reference to weather and you could have w0n your choice of an Arduino or a book published by AMetA.

Any suggestions for another competition??
