Weather: Winds heads-up!

[simonjk]

Hi,

Just wanted to bring your attention to the strength of the winds which will hit the UK on Monday and Tuesday.

Starting over Ireland on Monday morning, then spreading through the north and west by early afternoon, before crossing the rest of the UK in the afternoon and evening, gusts of over 70mph are likely on coasts.

The strongest winds probably ease for a few hours very early on Tuesday morning before returning across Wales and the southern half on England on Tuesday.

The charts here shows the gusts expected and the timing of them http://www.weatherweb.net/wxwebchartsgfsopukwindgust.php

It's one to take care of especially as strong winds are something we haven't experienced much in the past few weeks.

Keep the sun shining!

Better bring some more wood in for the fire!

I thought we told you we wanted better weather for 2013 Simon! It's not been a good start so far, we may have to find someone else to put in charge* of the weather...

* We assume you're in charge because you're the only one who always seems to be right!

One comment. It would be easier to use if you had the Next, Previous. Play button just above or below the chart. Otherwise very good. . Can I suggest that you have your name or weatherWeb prominently displayed? Otherwise the page is anonymous.

Another comment, Looking at HIRLAM and the GFS, does HIRLAM really have more information or just more data? Don you know what grid length HORLAM uses?

I am writing a Weather Handbook, pocket size for Reeds. I will add a ref to your page in one of my Appendix tables. I am not quoting any URLs because they change too much- eg YR.NO. What name do you want me to put – WeatherWeb? Let me know PDQ, please.

I know, I know, I must try harder....sorry everyone

Frank, thanks for the comment. Yes, plan is to get the controls to the top of the chart, I agree it would make life much easier. Pleased you like it though. More to come soon. Any suggests for areas are more than welcome.

HIRLAM is operating at a resolution of ~11km. I have not 'pushed' the info from it before because for the past year or so I have been evaluating it. However, I have to say, I have been really impressed. It's a 'proper' model Frank so not like the artificially created 'grid fillers'.

Thanks for adding the reference. yes, Weatherweb.net is fine...believe me, that company name won't change!

Thank you. Yes, I thought that HIRLAM used about 10 or 11 km. It is not surprising that HIRLAM is not a great deal different from the GFS. Although the Met Office still produces a 11 km model- the NAE – they do not regard it as operational. They find that it gives no significant improvement over the 25 km model.

My overall impression of the various models is that there is little difference in performance between them for the first few days and that the only virtue on looking at various models is because of random differences in the analysis. On any one occasion that can make one or another model do better or worse than the rest. In the longer term, using RMSE of surface pressure, I understand that ECMWF comes out best and the others half a step behind.

I do not understand your reference to a “proper model” not using “fillers.” I know that Movingweather used to interpolate between grid points to ridiculous levels. You could get three wind vectors in Southampton Water.. Some GRIB viewers eg zyGrib do automatically interpolate unless (as I do) just ask for winds at grid points. What other services fill in?

OK. I was checking on your company name. As I mention others, I may as well include you!
