Tech giants and commercial weather and climate prediction

Update: See also

Much like aerospace and telecommunications the world of weather prediction has been dominated by government departments and international organisations for most of its history. However in recent years things have really started to change. Sure there have always been one man and a dog private outfits selling wishful thinking to newspapers, much as the astrologers do, but detailed accurate forecasts for the last 25 years or so have always been the product of specialised computer models running on high performance computers, the so called supercomputers from makers such as Cray.

Every country in the world has a weather service, as a minimum it makes observations that it then shares as part of a global network and issues forecasts for civil aviation. Most do a great deal more, providing valuable services that protect life and property and enable effective use of natural resources for the production of food, energy, and more. Only the very largest and wealthiest run sophisticated computer models providing accurate forecasts for land, sea and air across the globe. However an established practice of international collaboration means that weather services in even the poorest, or poorly governed, countries have access to a constant stream of forecast model output, satellite imagery and other data.

So what are these recent changes? Well two recent, and significant, news story headlines look like this -

What do these developments mean for users of weather forecasts and the established national weather services? One way of trying to evaluate these developments is through the sort of tools and thinking used by MBA graduates.  These are the type of managers who are often brought in to make such business decisions in the first place, and also to evaluate the moves being made by rivals.
One such tool would be Porter's five forces, there's a simple introduction here at MindTools
In the case of Panasonic we find that they've moved from being one of many suppliers to one, albeit globally important, national weather service to being a rival forecasting service.   Apparently this wasn't planned, so also shows how it's now relatively simple to acquire and use the technology and expertise needed to "launch" a weather forecast model.

From 2004 to 2011 it also sold its airplane weather data to NOAA. In reviews of the usefulness of that Panasonic weather information, known as Tropospheric Airborne Meteorological Data Reporting, or TAMDAR, agency employees reported that it significantly improved their forecast skill.

But when budget cuts came, the agency stopped purchasing from Panasonic. The company shifted its business to making custom forecasts for the private sector, Jacobs said, even though its original business plan was based on selling to NOAA. April 2014

Most scientists, forecasters and administrators in the existing major government owned weather services are likely, for the time being, to react - So what? We've got forecasts that are at least as good and are continuing to improve, and in those smaller services that receive free forecasts from ECMWF and similar they'll be unable to imagine ever being in a position to buy an expensive commercial service. I expect the decisions as to what happens next will likely be made elsewhere, so their position might not be all that important. There are now commercial services that can directly substitute for what are very complicated public services involving international collaboration, rapid sharing of data, the development of space programmes, standards, and much more.  I'm impressed - this will, I'm sure, very quickly change the world I work in.

Tim Hunt and being #Dawkinsed

For a couple of days my Twitter notificiations have been flowing fast and furious.  Here's why.


Getting the last laugh is (I believed) a common English idiom.  It has nothing to do with belly laughs and little to do with jokes, hence what I felt was a cleverly constructed Tweet.  Let me explain; to me it means despite early ridicule a person goes on to achieve more than those who mocked. Usage might be something like this -

They mocked him at school for his shyness with girls but got the last laugh when he married the prettiest woman in the lab, followed by a Nobel prize!

Clearly achieving greatness and then being mocked is not getting the last laugh.

Long version for those with interest in who Professor Tim Hunt is, sock puppets and more

Right now, Tuesday evening, the number of retweets and favourites for Dawkins response stands at 53 retweets and 239 favourites.  Follow the link to check for any updates, and maybe check out who all these Dawkins fans are.

Odd eh?    So what's going on?    I'll fill in more as time permits but thought I'd better jot down some notes while I have time.   I did find this rather interesting, and probably relevant blog post that seems to relate, and well worth reading.

Distinguished Me

As for Dawkins's question, I assumed it was rhetorical, since If I was properly distinguished he'd already know who I was, and perhaps even leap to my defence - after all I'm a 50 year old white Englishman and lifelong atheist.  Well except as a young child, since my parents had the sense to protect me from indoctrination.  However I did go to school, so have a reasonable, if imperfect, command of my native language.  Which, IMHO, is the significant matter here.   What??? you screech in a determined effort to be offended by my lack of regard for a Nobel laureate.  Well take a look at this -

And if you favour the spoken word there's this -

Though not distinguished I am from time to time available for a chat.  So if you'd like to meet and discuss any of the things I do have real knowledge of, and Tim Hunt isn't one, I'll be in London a couple of times in coming weeks.

Digital Design Weekend at the V&A  26 and 27 September.


Mozilla Festival 7 and 8 November.

I'll make no claim that meeting me would justify the ticket price, but fortunately it's an absolute bargain anyway if you have even a passing interest in technology, the web, and our freedom to express ourselves online.

Final word

Afterword (10 Nov 2015)

The campaign to exonerate Tim Hunt for his sexist remarks in Seoul is built on myths, misinformation, and spin.
