We’ve been working on some updates over the past weeks which have been available to site Patrons (patreon.com/wxcharts) during development.
These changes are now live and available to all…so whats new?
With a second server now live we’ve started the process of adding some new models….
The most requested by patrons was UKMO data – unfortunately the UKMO do not make much of their data available for free (unlike most other major Met services) – but we’ve added what we can find. This is MSLP and 500 hPa information at hours t+72, t+96 and t+120.
CMC – CANADIAN
Next on the list of requests was data from the CMC (Canadian Met Centre) Global model. Most seem to know this by the name of GEM – for Global Enviromental Model, but as far as we can make out the correct name for this source is GDPS – Global Deterministic Prediction System. Charts for this model update twice daily and are made for all continental, regional and country sized regions. A wide selection of variables are available with the exception of convective parameters such as CAPE and Gusts.
Both the UKMO and CMC global model charts can be found by clicking the relevant selection in the top left and part of the control column:
With a growing list of model sources (and more on the way) the old version of the left hand control column was getting short on space, especially on smaller screens. Because of this we’ve opted for an accordion style system where only one of the “MODEL”, “REGION” or “CHART” lists can be viewed at one time. Just click on the one you require to expand it.
We also plan to develop an alternate grid-style selection system in the near future.
To go alongside our existing main overview (cloud, precip, pressure, temperature) and winter overview (precip, thickness, snow depth, pressure) charts we’ve added a third overview chart, called the “Convective Overview). This shows precipitation rate alongside contoured cape and either Bulk Shear barbs or 500 hPa contours depending on region size and availability.
The Convective Overview chart is available for all models that have the minimum of Precip rate and Cape available.
Locations now on GIFS
If you choose to show the location overlay, these will now be included when you make a GIF.
We plan to add a share/capture feature of static images which will merge the base chart and location overlay in the near future.
We plan to continue adding further model options and will be polling patrons soon to decide what should be next. Available options will include global ICON or regional COSMO data from the DWD, RDPS (regional det prediction system) or Ensemble data from CMC, Finnish Hirlam and Global ARPEGE from Meteo France.
We also plan to start adding more models to our database to allow creation of meteograms / skew-t plots.
There are also further new charts in the pipeline, and we haven’t forgotten about Observations – we’ll be returning to these to add more chart options and historical point plots.
We need help to fund our two Servers – with rental costs now nearly £500 per month. To have a direct say in how the site develops please consider becoming a site Patron by heading to http://patreon.com/wxcharts
The site is run on a non-profit basis in our spare time. Any income we make we plough back into the running of the site. We’re currently eating into our surplus to fund the second server, but will soon have a monthly shortfall so please join the community if you enjoy using the site and can afford to do so . Cheers!
