Gustav and Hannah On One Map – A Tropical Pair – 8-30-98

The graphic below is a splice of the WeatherUnderground plots showing the 5 pm Eastern Daylight Time 5-day forecast for Gustav and 3-day forecast for Hanna.  Remember that the forecast is not a line; please think in terms of the circles of uncertainty.

This splice is not perfect.  It lines up at the 25th parallel.

MAKE THE GRAPHIC LARGE WITH A SINGLE LEFT CLICK.

GFDL model – A GREAT SOURCE FOR AN ANIMATION!

To view an animation of the GFDL model, I recommend going to the following page, http://tc.met.psu.edu/ . This page is provided by the Penn State University Department of Meteorology. Scroll down to the GFDL horizontal column. Notice that there are three menus on that column and a submit button.

1) Select the most recent (highest) of the system you want to observe from the menu on the left.

2) Make sure the field indicates “sea level pressure.”

3) Select “Animation” on the right side menu if it’s not already there.

4) Click the “submit” button.

5) After the graphics come up, click the forward button on the right to watch the GFDL forecast.

It should loop but if it doesn’t click FWD once again.
