ECMWF MODEL RUN – THE EUROPEAN MODEL

When the European Center for Medium-Range Weather Forecast model is running, here is my favorite site for viewing:

For a lot of different reasons, but mainly because I enjoy the insights of Dr. Jeff Masters in his weather blog, I use WeatherUnderground.com.  For future reference, a link to his blog is under the Blogroll category at the right margin of this page.  In fact, it’s the first listed.

For the ECMWF Model Run, click on the following link and then follow my instructions exactly:  NOTE:  YOU MIGHT WANT TO COPY THE INSTRUCTIONS BECAUSE ONCE YOU CLICK ON THE LINK THIS PAGE WILL BE GONE UNLESS YOU CLICK BACK –

  1. At the upper left of the image, click on the “continent” tab.
  2. Scroll down the menu on the right margin and click in the box labeled “model data”.
  3. Another menu dropped down. Click on the “model” arrow and select ECMWF.
  4. Make sure the “map type” remains on MSL which stands for “mean sea level.”
  5. Click on the “forecast” arrow and wait patiently for the load.
  6. After it has loaded fully it should loop. If you want it to stop click on the button at “forecast.”

Though the European Model is not always right (none of them are) it has done the best job for the last two years in situations akin to this one with hurricane Irene.  The National Weather Service gives credence to this model though you will not see it indicated on the official spaghetti charts and such.  In fact, lately, the NWS official forecasts have been close to that of the ECMWF model runs or, if you please, the ECMWF model runs have been close to the official forecasts of the NWS.  To be sure, there will be times when there is little agreement – at which time I expect to lean toward the NWS advisories.

I LIKE IKE! (the President – Not the Storm!)

If I had been old enough to vote for Ike in 1953, I would have.  But I’m not thrilled with the “Ike” out there in the Atlantic today.  I have a very uncomfortable feeling about him.  Furthermore, it probably won’t be long before Josephine is on his tail.

Dr. Jeff Masters of WeatherUnderground.com in this afternoon’s discussion of tropical storm Ike does not envision it re-curving up the Atlantic during its approach on the Bahamas or Hispaniola.  However, he states that “our skill in predicting such things five days in advance is nil.”

None-the-less, at this moment – the longer range ECMWF has Ike in the Gulf of Mexico by Sept. 9. (European Center for Medium-Range Weather Forecasting).

If you are truly interested in concise and clear hurricane discussions I urge you to read Dr. Masters’ web-log at:

http://www.wunderground.com/tropical/

His statements which are pretty much daily during busy times of the hurricane season, are archived at the site.  I have been following his work for quite some time and have grown to enjoy his insight.

According to Dr. Masters, the GFDL and HWRF “are the only models that incorporate detailed depictions of the thermal structure of the Gulf of Mexico into their runs.”

I have been especially impressed with the GFDL over the last two or three years, the dynamic model from NOAA’s Geophysical Fluid Dynamics Laboratory. In my opinion, it did a very good job on the recent elusive storm, Fay.  I’m not sure that it has been correct to call Fay erratic.  It seems to me that it was the forecast models that were erratic.  What a tough job it is to try to figure out where a storm is going to track when the steering forces are so very weak as they were with Fay!

The image below is another attempt of mine to splice two images with scales that don’t match perfectly.  It was done for your convenience.
