  1. ARCHIVED CHARTS LIBRARY Please note that this archived charts library will evolve during the course of this year and we will be adding more topics as well as expanding on many of the existing topics – so please keep checking in. Introduction: Our small team who have been working on the Research Portal have been discussing various ways of expanding what it covers and add even more value to the service. Many of us who write specialist posts often wish to access archived charts to make comparisons with current output and forecasts. Many of these charts are not available in an archived format. Some sites that do have access to some of the old records are no longer updated and may close at any time in the future or have already closed with the data being lost. The purpose of this archived charts library is to provide access to this data. Some of it will simply be through a link to certain sites (such as some of the NOAA ENSO, MJO and Stratosphere records), some will be building up a comprehensive record of archived charts and some will involve both. Some charts (such as those for mountain torque) cover a 3 month period and (where available) 4 charts for each year may suffice. There will be many gaps which we hope to gradually fill in. Some historic information is simply not available. Trawling through past papers, presentations, archived threads and old posts from various forums and discussion groups as well as certain specialist meteorological websites, can often help to locate a few specific charts. Some data is behind a paywall. Sometimes the raw data is available but it would be very costly and time consuming to reproduce it. We are considering some of the options here and discussing this with the "33" forum administrators. If any member has access to particular archived data or access to some individual charts which will help us to fill in the gaps, then please PM any of our portal admin team with the links or the actual charts. Our team is currently (in alphabetical order): @Armando S (Armando), @Blessed Weather (Malcolm), @Bring Back 1962-63 (David) and @Snowy Hibbo (Zac). Each topic will appear on a separate page but as this library evolves, we shall see a good number of topics covered and some will be broken down into sub categories. These may not always be in the right order but there is a full index below. We will always welcome ideas, requests and feedback on our project at any time, particularly in this early development stage. Apart from PMing any of us, you can also use the Interactive Area in the Research Portal - just click on this link: Interactive Area for Members - Feedback and Comments Index to Archived Charts: This index will evolve steadily as we introduce new topics and sub categories. Some similar titles may appear more than once but will link to the same page.

  2. Introduction to the Research Portal We wish all visitors a very warm welcome to this Research Portal and we hope that there will be something useful here for everyone from early learners right through to professional meteorologists. The main purpose of the portal is to provide back-up and various types of support for the "Teleconnections: A More Technical Discussion" thread, "The Arctic Thread" and the "Stratospheric Discussion and Forecasting" thread (click on any of the titles for direct links) as well as some other specialist threads. Many of the features in this portal will evolve steadily over a period of time in a number of different ways. I summarise them below: Links to Research Papers and Specialist Sites There is a vast amount of information on teleconnections and related matters available through the internet. We are building up a library or store of research papers and articles - not the actual papers but the links to them. We are providing an abstract or summary of each paper which has been reviewed and allocated tags to enable specific topic searches so that you can easily find papers relating to your particular area of interest. Please refer to the "User Guide, Searching By Tag and Key To Tags" page for a full explanation on how to use this facility and a list of all the tags. Here's a direct link to that page: User Guide Index to Papers and Arcticles We have created a comprehensive "Index to Papers and Articles" page which lists all the titles under specialist topic headings. Where papers cover several topics the title will appear under multiple headings. Many visitors seem to prefer browsing through the index rather than completing a tag search. We recommend that you try out both of the options so that you can decide which one is your preference. Here's a direct link to that page: Index to Papers and Arcticles Where papers appear on the teleconnections or other specialist threads in any post, the link to that paper is quite likely to find its way into this portal. Some of the papers in the portal will be particularly relevant to a current topic and then one or more posts might appear on the thread with a review of the paper(s). We intend to prioritise adding a number of relevant papers to support some of the ongoing discussions and debates. To access data, charts, the models etc there are already links to various sites provided elsewhere on the forum. This is fine for standard purposes. Some sites (such as NOAA) are vast and certain specialist data and/or archive records can be very difficult to locate and can take many hours to find. We have been adding links to some of this data in the portal using the same process as for the research papers. You will be able to post comments about individual papers/articles/sites listed in the portal by using the standard "reply to topic" option on that particular page. You may wish to provide your own review of a specific paper and/or author and we shall be happy for these to appear. This might be particularly relevant to very recent papers. For more general comments see below. Interactive Area for Members Please note that we have provided an "Interactive Area for Members" where you will be able to give your views, comments, feedback and ideas about any aspect of this Research Portal by using the standard "reply to topic" option below that page. This might be used for a number of reasons including: 1. To help other visitors and researchers (e.g. recommending further reading and suggesting other suitable papers covering specific "teleconnection" related subjects). If you provide details, then we can add this (or these) to the portal. The full instructions, including an example paper and shown in the "Interactive Area". 2. You might wish to make comments or suggestions to the research portal moderators. For example you might be aware that a particular author or paper has been discredited or the paper or theory has been superseded or supplemented by a later paper. We do not wish to or cannot be "judge and jury" and we will rely on input and feedback from the readers. 3. You may wish to provide a link to a special site where you feel certain information/data/charts are very useful and this is not easy to find in a run of the mill search. Here's a direct link to that page: Interactive Area Future Development Plans for the Research Portal A feature that some of you might find very useful is a "Glossary of Terms and Short Definitions" section. This is intended to be more than a standard glossary as we are aiming to provide simple and concise dictionary type definitions of each of the teleconnections. This section is currently hidden as we have not had the time to develop hit. Our intention is to prioritise placing links to papers and articles into the Research Portal. Apart from links to papers and specialists sites, another exciting feature that we are planning for this Research Portal "will be" the"Learning Area". The main theme will be to provide various aids to assist everyone who wants to learn more about the teleconnections. There will be guides and direct access to educational sites. We will be producing a few of our own simple guides to "Understanding the Basics" of different teleconnections (such as the SPV - Stratospheric Polar Vortex or MT - Mountain Torque). These will usually contain helpful annotated charts and diagrams. The idea will be that those reading some of the more advanced posts on the main teleconnections thread may wish to learn more about the basics or to remind themselves of one or two of the key points. As each guide in the series is written, it would appear on the main thread. The learning area will provide access to the full list of the titles (with direct links to each one). This would allow any forum members to focus on them and perhaps read through a number of them at the same time. We may add a more advanced learning section at a later stage. Due to time constraints and the other priorities, it may be well into 2019 before we are ready to roll this out. Supporting the 33andrain Forum - Making a Donation As most members are probably aware, this site is run entirely by volunteers and weather enthusiasts. Many of us are happy to support and to contribute towards the ongoing development of this forum. There are substantial costs in maintaining the site, providing the software and developing new functionality. The space is hired and as the site expands, yet more space is required and costs start to escalate. This research portal is likely to take up a lot of space but we hope that many of the facilities will prove to be popular and will also help to attract new members. Some of you may wish to access many different papers and use the portal regularly. Whilst the portal moderators/editors/administrators are happy to provide their time on a purely voluntary basis out of their love for this wonderful subject we do need to ensure that all these costs are covered. Perhaps you might consider making a donation (or even an additional donation if you've already made one). The blue "Donate Today" tab appears at the top of this page or the donation table appears to right on this thread's homepage. Here's the link: Donate Please Note: If anyone wishes to discuss anything that appears on this page, please do so in our “Interactive Area”. Here’s the link: Interactive Area
  3. Learning All About the MJO (An Educational Paper) By: Professor Adrian Matthews (School of Environmental Sciences and School of Mathematics, University of East Anglia, Norwich, UK) Last Updated: 2016/17 Summary and Review (By Bring Back 1962-63 on 12th April, 2018): In my searches I came across this educational paper which I feel is one of the best that I have seen on introducing and explaining the MJO. It is very well written, easy to understand with some simple diagrams and charts. It contains many links for further learning including more advanced papers, many of which will appear in this research portal shortly. No title was shown, so I gave it one. This is how it starts off: ...."Introduction to the MJO: The tropical atmosphere-ocean system varies on many time scales, including: The diurnal or daily cycle, forced by the daily cycle of the sun due to the rotation of the Earth about its axis Synoptic weather systems (e.g., tropical cyclones, hurricanes, typhoons, and others) that last up to a few days Intraseasonal or month-to-month variability (the Madden-Julian oscillation). The seasonal/annual cycle, forced by the annual cycle of the sun due to the rotation of the Earth about the sun. Interannual or year-to-year variability, such as El Nino...."
